android Custom View display

            
Ask a question I want to use a custom GameView main.xml layout file, there have been unexpected stop condition
If the layout setContentView (R.layout.main); instead setContentView (gameView); no problem, but I also need to display a page other content

TestdActivity.java

public class TestdActivity extends Activity {
GameView gameView = null;
public void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);
gameView = new GameView (this);
setContentView (R.layout.main);
/ / SetContentView (gameView);
}
}


main.xml


android: layout_width = "fill_parent"
android: layout_height = "fill_parent"
android: orientation = "vertical">

android: layout_width = "wrap_content"
android: layout_height = "wrap_content"
/>



GameView.java

public class GameView extends View {

public GameView (Context context) {
super (context);
}

protected void onDraw (Canvas canvas) {
super.onDraw (canvas);
}
}


My GameView inside nothing to write, I do not know whether the layout file main.xml wrong, can yield components such as the GameView used
Because I need to show other groups such as button in a window, etc., which show how

When the components used, the constructor parameters changed to two.

There should be a problem constructor needs to be rewritten
public GameView (Context context, AttributeSet attributeSet)
{
supe (context, attributeSet);
}

To configure a custom View controls to xml file must be replicated supe (context, attributeSet) constructor, which is AttributeSet attributeSet parameter must have, otherwise configured to xml can not run,
public GameView (Context context, AttributeSet attributeSet)
{
supe (context, attributeSet);
}
