  • Resizing layouts for orientation change?

    - by Cole
    Normal: Landscape: See how the ListView overlaps other things on the screen when in landscape mode? How can I keep this from happening? XML: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:id="@+id/main" > <RelativeLayout android:id="@+id/myWishLists" android:layout_width="fill_parent" android:layout_height="50dp"> <Spinner android:id="@+id/spinner1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:prompt="@string/optionsSpinner" android:entries="@array/options" /> </RelativeLayout> <TextView android:id="@+id/myListsText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/myWishLists" android:layout_centerHorizontal="true" android:text="My Wish Lists" android:textStyle="bold" android:textAppearance="?android:attr/textAppearanceLarge" /> <RelativeLayout android:id="@+id/listsList" android:layout_width="fill_parent" android:layout_height="445dp" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true"> <ListView android:id="@+id/lists" android:layout_width="fill_parent" android:layout_height="fill_parent" android:entries="@array/entries" > </ListView> </RelativeLayout> </RelativeLayout>

  • Sharing a file from Android to Gmail or to Dropbox

    - by Calaf
    To share a simple text file, I started by copying verbatim from FileProvider's manual page: <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <provider android:name="android.support.v4.content.FileProvider" android:authorities="com.mycorp.helloworldtxtfileprovider.MainActivity" android:exported="false" android:grantUriPermissions="true" > <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/my_paths" /> </provider> <activity android:name="com.mycorp.helloworldtxtfileprovider.MainActivity" ... Then I saved a text file and used, again nearly verbatim, the code under Sending binary content. (Notice that this applies more accurately in this case than "Sending text content" since we are sending a file, which happens to be a text file, rather than just a string of text.) For the convenience of duplication on your side, and since the code is in any case so brief, I'm including it here in full. public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); String filename = "hellow.txt"; String fileContents = "Hello, World!\n"; byte[] bytes = fileContents.getBytes(); FileOutputStream fos = null; try { fos = this.openFileOutput(filename, MODE_PRIVATE); fos.write(bytes); } catch (IOException e) { e.printStackTrace(); } finally { try { fos.close(); } catch (IOException e) { e.printStackTrace(); } } File file = new File(filename); Intent shareIntent = new Intent(); shareIntent.setAction(Intent.ACTION_SEND); shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file)); shareIntent.setType("application/txt"); startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to))); file.delete(); } } Aside from adding a value for send_to in res/values/strings.xml, the only other change I did to the generic Hello, World that Eclipse creates is to add the following in res/xml/my_paths.xml (as described on the page previously referenced. <paths xmlns:android="http://schemas.android.com/apk/res/android"> <Files-path name="files" path="." /> </paths> This code runs fine. It shows a list of intent recipients. But sending the text file to either Dropbox or to Gmail fails. Dropbox sends the notification "Uploading to Dropbox" followed by "Upload failed: my_file.txt". After "sending message.." Gmail sends "Couldn't send attachment". What is wrong?

  • phpbb3 email settings for Zoho SMTP server

    - by SkylarMT
    I've spent a while guessing and googling, and haven't found an answer. In the past I setup my forums to send via my Gmail account, but spambots with fake emails have flooded my inbox, so I setup [email protected] with Zoho mail. Zoho works great, but I need to have my installation of phpbb3 send mass emails through the smtp.zoho.com mail server, and I can't figure out what settings I should use. The instructions on https://www.zoho.com/mail/help/pop-access.html are a little vague for anything that doesn't auto-detect the exact settings.

  • Android ListView appears empty, but contains objects

    - by Lethjakman
    I'm having a really odd problem with my android listview. The listview is inside of a fragment, everything's compiling and I'm no longer getting a nullpointer error, but the listview is appearing empty. Even though it's appearing empty, the log is stating that the listview has 385 objects. I can't figure out why it's empty. I do get a blue fragment, and the listview is populated. Any ideas? How I set the adapter: ActivePackages = getList(); LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); LinearLayout mContainer = (LinearLayout) inflater.inflate(R.layout.tab_frag1_layout, null); ListView activeList = (ListView) mContainer.findViewById(R.id.activelist); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, ActivePackages); Log.i("valueof activeList",String.valueOf(activeList.getCount())); //returns 0 activeList.setAdapter(adapter); adapter.notifyDataSetChanged(); Log.i("valueof activeList",String.valueOf(activeList.getCount())); //returns 385. This is the xml for the fragment: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ListView android:id="@+id/activelist" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#0073fd"> </ListView> </LinearLayout>

  • Android, FragmentActivity and prevent Swipe

    - by FIG-GHD742
    I use android.support.v4.app.FragmentActivity for create a app with multi fragment/panels that can be access by drag/swipe between different part of the app. In one of my fragment I has a zoomable view and my problem is in case I is on the zoomable view I will prevent the use for drag/swipe to a other fragment. I has try to hack into android.support.v4.view.ViewPager for get the action from on Touch event but not work. I has try all of this case but not work: (All code is a a part of subclass to android.support.v4.view.ViewPager) Case 1: // Not working @Override protected void onPageScrolled(int position, float offset, int offsetPixels) { if (isPreventDrag()) { super.onPageScrolled(position, 1, 0); } else { super.onPageScrolled(position, offset, offsetPixels); } } Case 2: // Work but stop all event include the event to the target image view. @Override public boolean onInterceptTouchEvent(MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_DOWN: lastX = ev.getX(); // float lockScroll = false; return super.onInterceptTouchEvent(ev); case MotionEvent.ACTION_MOVE: this.lockScroll = this.isPreventDrag(); break; } if (lockScroll) { ev.setLocation(lastX, ev.getY()); return super.onInterceptTouchEvent(ev); } else { return super.onInterceptTouchEvent(ev); } } Case 3: // Work good, but by some unknown error I can drag the screen // some pixels before this stop the event. @Override public boolean onTouchEvent(MotionEvent ev) { if (this.isPreventDrag()) { return true; } else { return super.onTouchEvent(ev); } } I want a easy way to deactivate stop or deactivate if the use is allow to switch to a other Fragment. Here is a working code for me, I don't know what error I do before. // This work for me, @Override public boolean onInterceptTouchEvent(MotionEvent ev) { if (this.isPreventDrag()) { return false; } else { return super.onInterceptTouchEvent(ev); } }

  • Unable to stretch TableLayout to screen width

    - by Rendrik
    I've tried unsuccessfully for quite a few hours now to simply get a TableLayout to scale to the full screen. I've tried stretchColumns, shrinkColumns, (specifying the column index or using *) you name it. It's almost as if the parent element (TableLayout) is completely ignoring 'android:layout_width="fill_parent"'. I've read through similar questions here, though they haven't solved it for me. The XML below has 3 rows, and the table always shrink wraps to the size of the content. Apparently I'm too new to post pictures(?) Here is the XML rendered into the project i'm working on. http://www.dashiva.com/images/Capture.png What am I missing here, it's quite frustrating! <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:stretchColumns="*"> <TableRow> <TextView android:id="@+id/AmountText" android:text="@string/general_amount" android:paddingRight="8dip" android:layout_gravity="center"></TextView> <TextView android:id="@+id/CardText" android:text="@string/general_card" android:paddingRight="8dip" android:layout_gravity="center"></TextView> <TextView android:text="@string/general_date" android:id="@+id/DateText" android:paddingRight="8dip" android:layout_gravity="center"></TextView> <TextView android:id="@+id/ErrorText" android:text="@string/general_error" android:paddingRight="8dip" android:layout_gravity="center"></TextView> </TableRow> <TableRow> <TextView android:text="Amount here..." android:id="@+id/AmountNum" android:paddingRight="8dip" android:layout_gravity="center"></TextView> <TextView android:id="@+id/CardNum" android:text="Num here..." android:paddingRight="8dip" android:layout_gravity="center"></TextView> <TextView android:text="date here..." android:id="@+id/DateDate" android:paddingRight="8dip" android:layout_gravity="center"></TextView> <TextView android:text="Code here..." android:id="@+id/ErrorCode" android:paddingRight="8dip" android:layout_gravity="center"></TextView> </TableRow> <TableRow> <ImageView android:id="@+id/cc_image" android:src="@drawable/mastercard" android:background="@drawable/row_bg2" android:layout_gravity="center" android:layout_weight="1"></ImageView> <TextView android:id="@+id/ResponseText" android:layout_span="4" android:text="Response text here..." android:textSize="18dip" android:layout_weight="1"></TextView> </TableRow> <ImageView android:layout_gravity="center_vertical" android:background="@drawable/gradient_bg" android:layout_height="3dip" android:layout_width="fill_parent"></ImageView> </TableLayout>

  • Newbie question: How do you layout an icon, 2 text lines and a button?

    - by Keith Barrows
    I am trying to extend a sample I found at http://developer.android.com/resources/articles/layout-tricks-efficiency.html. I am a brand new MonoDroid developer, just installed it yesterday, and trying to jump right into UI design and so far it is not clicking for me completely. I have this main.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_marginRight="6dip" android:src="@drawable/icon" /> <TextView android:id="@+id/secondLine" android:layout_width="200dip" android:layout_height="26dip" android:layout_toRightOf="@id/icon" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:singleLine="true" android:ellipsize="marquee" android:text="Second line which is a long line of text and needs to scroll" /> <TextView android:id="@+id/firstLine" android:layout_width="200dip" android:layout_height="wrap_content" android:layout_toRightOf="@id/icon" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_above="@id/secondLine" android:layout_alignWithParentIfMissing="true" android:singleLine="true" android:ellipsize="marquee" android:gravity="center_vertical" android:text="First line" /> <Button android:id="@+id/logonButton" android:layout_width="50dip" android:layout_height="wrap_content" android:layout_toRightOf="@id/secondLine" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:gravity="center_vertical" android:text="Login" /> /> </RelativeLayout> What I am trying to do is have an icon on the left, 2 lines of text stacked in the middle and a button on the right. When I run this in my emulator I am seeing: The second line is not scrolling. The button does not show up. Is there by any chance a simple WYSIWYG editor for layout? Or is there an app to give me a quick view of my layout XML? Something like FireBug in FireFox would be fine. Barring the slim chance there are UI helpers for Droid, what am I doing wrong? :)

  • Unable to Start Activity ComponentInfo when Starting a New Activity

    - by Timtim17
    {I know there's already a whole bunch of questions like this, but I can't see any problems that related to my program.} I have an Android App that is supposed to take a name from a EditText and put it in a TextView in another activity. It previously worked, but then I wanted it to start another activity if the EditText's value was equal to "ANDROID". However, now the app crashes whenever I try to start either activity. First Activity: package net.timtim17.dev.android.fun.nametag; import android.os.Bundle; import android.app.Activity; import android.content.Intent; import android.view.View; import android.view.View.OnClickListener;

  • Android: Adding extended GLSurfaceView to a Layout don't show 3d stuff

    - by Santiago
    I make a game extending the class GLSurfaceView, if I apply SetContentView directly to that class, the 3d stuff and input works great. Now I want to show some items over 3d stuff, so I create a XML with a layout and some objects, and I try to add my class manually to the layout. I'm not getting errors but the 3d stuff is not shown but I can view the objects from XML layout. source: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); layout = (RelativeLayout) inflater.inflate(R.layout.testlayout, null); //Create an Instance with this Activity my3dstuff = new myGLSurfaceViewClass(this); layout.addView(my3dstuff,4); setContentView(R.layout.testlayout); } And testlayout have: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/Pantalla"> <ImageView android:id="@+id/zoom_less" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/zoom_less"></ImageView> <ImageView android:id="@+id/zoom_more" android:layout_width="wrap_content" android:src="@drawable/zoom_more" android:layout_height="wrap_content" android:layout_alignParentRight="true"></ImageView> <ImageView android:id="@+id/zoom_normal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/zoom_normal" android:layout_centerHorizontal="true"></ImageView> <ImageView android:id="@+id/stop" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/stop" android:layout_centerInParent="true" android:layout_alignParentBottom="true"></ImageView> </RelativeLayout> I also tried to add my class to XML but the Activity hangs up. <com.mygame.myGLSurfaceViewClass android:id="@+id/my3dstuff" android:layout_width="fill_parent" android:layout_height="fill_parent"></com.mygame.myGLSurfaceViewClass> and this don't works: <View class="com.mygame.myGLSurfaceViewClass" android:id="@+id/my3dstuff" android:layout_width="fill_parent" android:layout_height="fill_parent"></View> Any Idea?

  • Nested Linear layout only shows first view after being set from gone to visible in Android

    - by Adam
    Hi guys, I am developing an Android app but I'm still pretty new. I want to have a button, and when you push that button, a few TextViews and Buttons will appear. So I have a main linear layout, and then another linear layout nested inside containing the things I want hidden. I have the nested linear layout set to android:visibility="gone". The problem I am having is that it only shows the first item inside the hidden linear layout instead of all of them. The way I try to make it appear is vgAddView = (ViewGroup)findViewById(R.id.add_details); btnAche.setOnClickListener(new OnClickListener(){ public void onClick(View v){ vgAddView.setVisibility(0); } }); My XML file is this <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:text="@string/but_stomach_ache" android:id="@+id/but_stomach_ache" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> <Button android:text="@string/but_food" android:id="@+id/but_food" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/add_details" android:visibility="gone"> <TextView android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/when_happen"> </TextView> <Button android:text="@string/happen_now" android:id="@+id/happen_now" android:layout_width="fill_parent" android:layout_height="wrap_content"> </Button> </LinearLayout> </LinearLayout>

  • Android local search

    Hi! I'm trying to implement a local search in my activity.

  • How do you set Android ViewPager to encompass only one View or Layout?

    - by Kyle
    I am struggling with the concepts needed to properly implement a view pager. By following some tutorials and referencing developer.android.com, I am able to get a view pager almost fully functional. The pager will flip through several text views that have been setup to say "My Message 0" through "My Message 9". The problem is that the view pager also flips the button on the bottom of the activity and the red block that is right above the button. I would like to have the view pager only cycle through the text. Would you please help me understand what I'm doing wrong? I have an activity that represents a dashboard: public class DashBoard extends FragmentActivity { private static final int NUMBER_OF_PAGES = 10; private ViewPager mViewPager; private MyFragmentPagerAdapter mMyFragmentPagerAdapter; public void onCreate(Bundle icicle){ super.onCreate(icicle); setContentView(R.layout.dashboard); mViewPager = (ViewPager) findViewById(R.id.viewpager); mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager()); mViewPager.setAdapter(mMyFragmentPagerAdapter); } private static class MyFragmentPagerAdapter extends FragmentPagerAdapter{ public MyFragmentPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int index) { return PageFragment.newInstance("My Message " + index); } @Override public int getCount(){ return NUMBER_OF_PAGES; } } and a class for the page fragment: public class PageFragment extends Fragment { public static PageFragment newInstance(String title){ PageFragment pageFragment = new PageFragment(); Bundle bundle = new Bundle(); bundle.putString("title", title); pageFragment.setArguments(bundle); return pageFragment; } @Override public void onCreate(Bundle icicle){ super.onCreate(icicle); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle icicle){ View view = inflater.inflate(R.layout.dashboard, container, false); TextView textView = (TextView) view.findViewById(R.id.textViewPage); textView.setText(getArguments().getString("title")); return view; } } and finally, my xml for the dashboard: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/dashbaordLabel" android:layout_width="match_parent" android:layout_height="wrap_content" > <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" /> <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> <Button android:id="@+id/newGoalButton" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/stringNewGoal" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:onClick="createNewGoal" /> <RelativeLayout android:id="@+id/SpaceBottom" android:layout_width="match_parent" android:layout_height="75dp" android:layout_above="@id/newGoalButton" android:background="@color/red" > </RelativeLayout> </RelativeLayout> A note about my xml, I tried wrapping the text view in some view pager tags eg: <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" > <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> </android.support.v4.view.ViewPager> But all that did was make the text view disappear from the screen, while the button and red block still cycled as in the original issue.

  • Sending emails - providers

    - by nrph
    I need to send emails from my social service (this is continuation of Experiences in mailing to registered users). I got strong feeling that it's better to avoid problems with email server configuration and maintance and to choose email provider which will take care of all painful problems. So several offers were compared: http://imgur.com/JkK2X.jpg Three of them look very attractive: Postageapp / Sendgrid / CritSend Which provider works for you and is worth choosing?

  • Remote Email Access?

    - by Tyler
    I have remote email access from an iPhone or my Android phone, but I cannot setup a Windows Email Client to check my email using the exact same information I provided in my phones. The email system is an Exchange 2003 and I hate using the cheap Outlook Web App that it has. User: [email protected] Password: 1234 Server: mail.domain.com And that works for they phones. So why can't I get it to work on my email client? Maybe a DNS problem?

  • Email deliverability -- Whitelist solution or Email delivery service?

    - by JoefrshnJoeclean
    Hey Folks -- our company is encountering the same recurring problem - email deliverability. A lot of our emails are still getting trapped in yahoo and gmail spam filters. We followed yahoo's best practices guide as well as tips Ive found on serverfault. (setting up DKIM, SPF) And even took the Email Server Test (http://www.allaboutspam.com/email-server-test/) Now my question is: has anyone had success using whitelist solutions like goodmail or EmailReach? Alternatively, Im beginning to think that going with a email delivery service like Mailchimp will save me the headache and future stress of managing our email lists. So whitelist solution or just fork up the money and send via an email delivery service? Thanks!
