Android:How to add a button in surface view

Question

I'm drawing some graphics and i would like to add a couple of buttons to it. But with the surface view how do we add these buttons programatically ?

Answer 1

Enclose your surfaceView with a FrameLayout in your xml Layout. Then add your buttons to the same FrameLayout. Make sure they are placed below the surface view so they get drawn on top of it. (Might be a good idea to bundle them in another Layout and add that to the FrameLayout.)

<FrameLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
    <SurfaceView android:id="@+id/surfaceView1" android:layout_width="wrap_content" android:layout_height="wrap_content"></SurfaceView>
    <LinearLayout android:id="@+id/linearLayout1" android:layout_width="wrap_content" android:layout_height="wrap_content">
        <Button android:text="Button" android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
        <Button android:text="Button" android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
    </LinearLayout>
</FrameLayout>

Thank you so much Androidica..

Your xml has helped me to figure out the following solution programatically without using any xml..

public class LudoActivity extends Activity implements OnClickListener {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);

        FrameLayout game = new FrameLayout(this);
        GameView gameView = new GameView (this);
        LinearLayout gameWidgets = new LinearLayout (this);

        Button endGameButton = new Button(this);
        TextView myText = new TextView(this);

        endGameButton.setWidth(300);
        endGameButton.setText("Start Game");
        myText.setText("rIZ..i");

        gameWidgets.addView(myText);
        gameWidgets.addView(endGameButton);       

        game.addView(gameView);
        game.addView(gameWidgets);

        setContentView(game);
        endGameButton.setOnClickListener(this);
    }

    public void onClick(View v) {
         Intent intent = new Intent(this, LudoActivity.class);
         startActivity(intent);
         // re-starts this activity from game-view. add this.finish(); to remove from stack
    }
}

while GameView is;

public class GameView extends SurfaceView {

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

        /*
         * your code
         */
    }
}
