reposted here from the android developers group because this is a beginner question; sorry about the duplication
I got a simple layout working and displaying by only editing the layout xml. Basically it was the layout below without my BoardView in there. Now I'm trying to write my own View class to handle various onFoo() events, using LunarLander as an example. Here's my simple layout and class: <?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" <com.my.package.BoardView android:id="@+id/board" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <TextView android:id="@+id/TopText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="play area" /> <LinearLayout android:id="@+id/rowButtons" android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" > <Button android:id="@+id/btnPlay" android:text="Play" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <Button android:id="@+id/btnInfo" android:text="Info" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <Button android:id="@+id/btnSetup" android:text="Setup" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> <TextView android:id="@+id/InfoText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="screen size:" /> </LinearLayout> public class BoardView extends SurfaceView { public BoardView(Context context, AttributeSet attrs) { super(context, attrs); } @Override protected void onSizeChanged(int w, int h, int oldw, int oldh) { // TODO Auto-generated method stub super.onSizeChanged(w, h, oldw, oldh); TextView info = (TextView) findViewById(R.id.InfoText); //info.setText("width : " + w + ", height : " + h); } } When I first ran it, it blew up with a NPE in onSizeChanged. So at least I knew it was getting there. I commented out the info.setText line and it ran fine, but the view is blank on the screen. Why are the various TextViews and buttons not visible? I couldn't find any guidelines in the docs as to how/where to place your View class in the layout.xml. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
