java - Android 切换 Activity 后无法单击按钮

Question

我正在将 Activity 从 SurfaceView(游戏内 Activity)切换到 MenuActivity。

切换后，我的听众不再使用我的按钮。

My menu activity
public class MenuActivity extends Activity {

    private ImageButton startButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.d("Switchujem","test");

        setContentView(R.layout.main_activity);

        initButtons();
    }

    public void playGame(View view){
        Constants.mediaPlayer.stop();
        Intent game = new Intent(Constants.context, GameActivity.class);
        startActivity(game);
    }

    private void initButtons(){

        //INIT PLAY BUTTON
        startButton = (ImageButton) findViewById(R.id.playButton);
        startButton.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.d("Click","ME");
                switch(event.getAction()) {
                    case MotionEvent.ACTION_DOWN:
                        // Do something
                        startButton.setImageResource(R.drawable.play_clicked);
                        return true;
                    case MotionEvent.ACTION_UP:
                        startButton.setImageResource(R.drawable.play);
                        playGame(startButton.getRootView());
                        return true;
                }
                return false;
            }
        });
    }

}

GameView切换方法

    public void update(){
        ....

        if(player.isDead()) {
            Log.d("DEAD", String.valueOf(player.isDead()));
            mediaPlayer.stop();
            Intent i = new Intent(this.context, MenuActivity.class);
            context.startActivity(i);
            thread.setRunning(false);
            ((GameActivity) context).switchScene();
        }
    }

GameActivity切换方法

    public void switchScene(){
        Intent menu = new Intent(this.getApplicationContext(), MainActivity.class);
        startActivity(menu);
    }

我开始游戏后我的游戏 Activity 像这样运行:1.MainActivity -> 只需初始化一些常量并运行 MenuActivity2.MenuActivity ->现在一切正常，按钮可以点击3.GameActivity(带有自定义GameView)->当我切换回菜单 Activity 按钮时不可点击。

更新::我终于切换了场景，但切换游戏崩溃了。这是我现在的输出:

您的回调被错过了，所以当您进入 GameActivity 时，它们被错过了，所以像这样重写 onResume() :

@Override
public void onResume(){
    super.onResume();
    initButtons();

}

希望这有帮助
