Adding View extending from SurfaceView to layout gives me a blank screen

- by JonF

I'm very new to Android programming, so this is probably something pretty basic. I just have an xml layout with a few buttons. I'm trying to follow the model given by the JetBoy demo, so I'm adding a view to the layout which extends SurfaceView. When this new view is put in my xml layout, I just get a blank screen. Here's the XML layout if it helps. The gameview element is what causes the screen to be blank <?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" android:alwaysDrawnWithCache="true"> <game.test.gameEngine android:id="@+id/gameView" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <Button android:text="Easy" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/EasyButton"></Button> <Button android:text="Medium" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/MedButton"></Button> <Button android:text="Hard" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/HardButton"></Button> <DatePicker android:id="@+id/DatePicker01" android:layout_width="wrap_content" android:layout_height="wrap_content"></DatePicker><Button android:id="@+id/Button04" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Exit"></Button> </LinearLayout>

Make part of layout invisible and the other part visible

- by JonF

I would like to make a LinearLayout that was created from xml invisible, and another LinearLayout visible to replace it. The replacement layout starts out as invisible. When I make the originally visible layout invisible, it still leaves space for it on the screen. How can I refresh the screen so that space is gone?

Android pattern locking

- by JonF

I have been able to lock the screen using LOCK_PATTERN_ENABLED, however in many cases when I enable this pattern locking it will take any pattern and move past the pattern check. Has anyone else run across this?

Continuously checking database from a Windows service

- by JonF

I am making a Windows service which needs to continuously check for database entries that can be added at any time to tell it to execute some code. It is looking to see if it's status is set to pending, and it's execute time entry is than the current time. Is the only way to do this to just run select statements over and over? It might need to execute the code every minute which means I need to run the select statement every minute looking for entries in the database. I'm trying to avoid unneccesary cpu time because I'm probably going to end up paying for cpu cycles on the hosting provider

Basically I just can a icon that they can press which will flip the value of a boolean in the broadcast receiver, and change the icon to indicate something happened. I think I need to do something with a widget? Could anyone point me in the direction of some tutorial I could check out?

Displaying bitmaps in relative positions

- by JonF

I'd like to put a couple images on a surfaceview. I understand that the screen sizes of android devices can vary, so I don't think I can just use an x y position or I might end up placing it off different screens. Say I want to put two boxes in the center of the screen, a blue one and a red one. The blue one is to the left of the red one. How can I accomplish that while accounting for different screen sizes?

Troubleshooting occasional timeout of select() in windows

- by JonF

I'm having an occasional problem with select() timing out on me. I have it set for twenty seconds. The system will handle 100's of transactions correctly, but occasionally one fails with the selet timing out. It does about 1 transaction every few seconds, opening and closing the tcp conncetion with each transaction. I thought the server my app was connecting to might have to many connection attempts pending, but no 4226 events are showing up in the logs One more point thing I noticed when using wireshark that I'm getting a SYN,RST in response to the SYN I am appearently sending. This only happens a few times over the first second or two, then I don't see any more activity in Wireshark

Modify Gridview as it's being rendered through javascript

- by JonF

I'm trying to modify a field in each row of my gridview as it is rendered. I need to modify it with client side Javascript. I'm somewhat new to asp.net, but I think I should be doing something with clientscriptmanager. I came up with a simple scenario which is basically what I want to do to avoid getting bogged down in the details. If I could accomplish the following I could accomplish my goal. Say I have a grid view of names and salaries. I want to double each persons salary before displaying it. Obviously I can do it in the code behind, but due to the nature of the more complex actual thing I'm doing, I need to do it in javascript <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" onrowdatabound="GridView1_RowDataBound" > <Columns> <asp:BoundField HeaderText="Full Name" DataField="Name" ></asp:BoundField> <asp:BoundField HeaderText="Salary" DataField="Salary" /> </Columns>

Finding databases for use in applications

- by JonF

Does anyone have some recommendations on how I can find databases for random things that I might want to use in my application. For example, a database of zip code locations, area code cities, car engines, IP address locations, or whatever. I'm just asking generally when you decide you need a bunch of data where are some good places to start looking other than google?
