添加按钮在Android的自定义视图 [英] Add Button on custom View in Android

问题描述

我有下面的类

I have the following class

public class GameActivity extends Activity {
   @Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      View gameView = new GameView(this);
      setContentView(gameView);
   }
}

现在我想将按钮添加到我的课GameView。

and now I'd like to add a Button to my class GameView.

public GameView(Context context) {
        super(context);
// Code ...
}

我在我的游戏过程中需要这个键，所以它应该是在所有其他的帆布我画的前面alywas。
我该怎么办呢？

I need this button during my game, so it should be alywas in front of all the other canvas' I'm drawing.
How can I do that?

推荐答案

你想创建一个新的按钮？

                                   LayoutParams.WRAP_CONTENT)); 

gameView.addView(b);

使用的ViewGroup 为 GameView 父insted的简单视图

Use ViewGroup as GameView parent insted of simple View

ViewGroup gameView = new GameView(this);


public class GameView extends ViewGroup { //...
