• 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? :)

• My google map android app keeps crashing

  - by Manny264

  I have followed about two tutorials from vogella and some other tutorial that looked similar...very similar but to no avail. I load the app on my nexus 7 and it just crashes "Unfortunately MyMapView has stopped working" on launch.This is the manifest: ` <uses-sdk android:minSdkVersion="17" android:targetSdkVersion="17" /> <uses-feature android:glEsVersion="0x00020000" android:required="true"/> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <uses-library android:name="com.google.android.maps" /> <activity android:name="com.macmozart.mymapview.MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="AIzaSyBZ1Bt7rjB863Jy-B05zls6k8XZsBGQ6-4" /> </application> ` Followed by my main layout: <fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.MapFragment" /> and finally my java class: package com.macmozart.mymapview; import android.app.Activity; import android.os.Bundle; import com.google.android.gms.maps.CameraUpdateFactory; import com.google.android.gms.maps.GoogleMap; import com.google.android.gms.maps.MapFragment; import com.google.android.gms.maps.model.BitmapDescriptorFactory; import com.google.android.gms.maps.model.LatLng; import com.google.android.gms.maps.model.Marker; import com.google.android.gms.maps.model.MarkerOptions; import com.google.android.maps.*; public class MainActivity extends Activity { static final LatLng HAMBURG = new LatLng(53.558, 9.927); static final LatLng KIEL = new LatLng(53.551, 9.993); private GoogleMap map; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)) .getMap(); if (map != null) { Marker hamburg = map.addMarker(new MarkerOptions() .position(HAMBURG).title("Hamburg")); Marker kiel = map.addMarker(new MarkerOptions() .position(KIEL) .title("Kiel") .snippet("Kiel is cool") .icon(BitmapDescriptorFactory .fromResource(R.drawable.ic_launcher))); map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15)); // Zoom in, animating the camera. map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null); } } } Any idea what im doing wrong I really need this to work

• 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;

if(text.equals("ANDROID")){ Intent android = new Intent(MainActivity.this, AndroidNameTag.class); startActivity(android); }else{ Intent intent = new Intent(MainActivity.this, NameTag.class); intent.putExtra("name", text); startActivity(intent); } } }); } } NameTag Activity: package net.timtim17.dev.android.fun.nametag; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class NameTag extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

• 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>

• 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.

• Android project problem

  - by qwerty

  Hello, here I uploaded my Android project made in Eclipse. The idea is that i have a service, which computes the sum of two random numbers. But when i press the OK Button, i don't see the result in that edit box... why? What i'm doing wrong? Please help Thanks! EDIT: The code: //service class package service; import java.util.Random; import com.android.AplicatieSuma; import android.widget.EditText; import android.widget.TextView; public class ServiciuSuma { public ServiciuSuma() { } public int CalculateSum() { Random generator=new Random(); int n=generator.nextInt(); int m=generator.nextInt(); return n+m; } } The Application class: package com.android; import android.app.*; import service.*; public class ApplicationSum extends Application { public ServiciuSuma service = new ServiciuSuma(); } and the main Activity class: package com.android; import com.android.R; import android.app.Activity; import android.content.Intent; import android.graphics.Color; import android.graphics.PorterDuffColorFilter; import android.graphics.drawable.Drawable; import android.graphics.PorterDuff; import android.os.Bundle; import android.provider.Settings; import android.view.View; import android.view.View.OnClickListener; import android.widget.EditText; import android.view.Menu; import android.view.MenuInflater; import android.view.MenuItem; public class Activitate extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); View btn_ok = findViewById(R.id.btn_ok); btn_ok.setOnClickListener(new OnClickListener() { public void onClick(View v) { CalculeazaSuma(); } }); } private void CalculeazaSuma() { AplicatieSuma appState = ((AplicatieSuma)this.getApplication()); EditText txt_amount = (EditText)findViewById(R.id.txt_amount); txt_amount.setText(appState.service.CalculateSum()); //BindData(); } } So that edit text does not show the sum of the random generated numbers, by the service. What's wrong?

• Android Augmented Reality

  - by Azooz Totti

  I'm working on my first Android Augmented Reality application. The application works pretty good if the ARActivity runs as the first class (android.intent.category.LAUNCHER) in the manifest file. But when I added a splash screen which means the ARActivity will be the second to run(android.intent.category.DEFAULT), the camera seems not detecting the marker. I believe the problem is all in the manifest file. Any suggestions ?

• What is the best practice for using lock within inherited classes

  - by JDMX

  I want to know if one class is inheriting from another, is it better to have the classes share a lock object that is defined at the base class or to have a lock object defined at each inheritance level. A very simple example of a lock object on each level of the class public class Foo { private object thisLock = new object(); private int ivalue; public int Value { get { lock( thisLock ) { return ivalue; } } set { lock( thisLock ) { ivalue= value; } } } } public class Foo2: Foo { private object thisLock2 = new object(); public int DoubleValue { get { lock( thisLock2 ) { return base.Value * 2; } } set { lock( thisLock2 ) { base.Value = value / 2; } } } } public class Foo6: Foo2 { private object thisLock6 = new object(); public int TripleDoubleValue { get { lock( thisLock6 ) { return base.DoubleValue * 3; } } set { lock( thisLock6 ) { base.DoubleValue = value / 3; } } } } A very simple example of a shared lock object public class Foo { protected object thisLock = new object(); private int ivalue; public int Value { get { lock( thisLock ) { return ivalue; } } set { lock( thisLock ) { ivalue= value; } } } } public class Foo2: Foo { public int DoubleValue { get { lock( thisLock ) { return base.Value * 2; } } set { lock( thisLock ) { base.Value = value / 2; } } } } public class Foo6: Foo2 { public int TripleDoubleValue { get { lock( thisLock ) { return base.DoubleValue * 3; } } set { lock( thisLock ) { base.DoubleValue = value / 3; } } } } Which example is the preferred way to manage locking within an inherited class?

• How to add a Fragment inside a ViewPager using Nested Fragment (Android 4.2)

  - by sabadow

  I have a ViewPager with three Fragments, each one shows a List (or Grid). In the new Android API level 17 (Jelly Bean 4.2), one of the features is Nested Fragments. The new functionality description says: if you use ViewPager to create fragments that swipe left and right and consume a majority of the screen space, you can now insert fragments into each fragment page. So, if I understand right, now I can create a ViewPager with Fragments (with a button inside for example) inside, and when user press the button show another Fragment without loose the ViewPager using this new feature. I expend my morning trying to implement this on several ways but I can´t made it... Can somebody show a simple example of how to do this? PS: I'm only interested in doing at this way, with getChildFragmentManager to learn how works.

• Android Emulator - Cannot get keyboard to display

  - by Ash

  Basically I cannot get the onscreen keyboard to display at all. I've tried every solution I've read to make it appear within my application, and now I've come to the conclusion that it must be the emulator as it isn't appearing when using Messages, writing e-mails etc. I've looked in Language & input within settings and checked Sample Soft Keyboard, rebooted the emulator with no change. Using Android SKD 2.3.3 3.7in WVGA (Nexus One) I'm hoping someone can maybe guess what's going on. Many thanks
