当我的自定义视图失去焦点时(当按下 LockScreen 按钮时)我试图播放/暂停音乐到应用程序以后的音乐不播放。任何人都可以帮助我或告诉我我缺少什么 Api 级别是 8-16。提前感谢
公共类 StartGameActivity 扩展 BaseActivity 实现 OnFocusChangeListener { 私有 PuzzleView 拼图视图;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// custom View for activity set to focusable(true), & focusable
// inTouchmode(true)
puzzleview = new PuzzleView(this);
puzzleview.setOnFocusChangeListener(this);
setContentView(puzzleview);
}
protected void onResume() {
super.onResume();
}
protected void onPause(){
super.onPause();
StopMusic();
}
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
Initialize_Music_Player():
}
if (!hasFocus) {
StopMusic();
}
}
}
