bug在demo中没有复现,发现只在RecyclerView中适配器里面,才会出问题。解决方案是停止播放的代码需要加两行代码,如下:
animationDrawable.stop();
animationDrawable.selectDrawable(0);
ivPlaySound.setImageDrawable(null);
ivPlaySound.setImageResource(R.drawable.animate_sound_play);
完整Activity代码:
public class MainActivity extends AppCompatActivity {
ImageView ivPlaySound;
private AnimationDrawable animationDrawable;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ivPlaySound = findViewById(R.id.iv_play_sound);
}
public void startAnim(View view) {
Log.i("xx", "开始");
animationDrawable = (AnimationDrawable) ivPlaySound.getDrawable();
animationDrawable.start();
}
public void stopAnim(View view) {
Log.i("xx", "结束");
animationDrawable.stop();
animationDrawable.selectDrawable(0);
// RecyclerView中停止,需要加下面这两行代码
// ivPlaySound.setImageDrawable(null);
// ivPlaySound.setImageResource(R.drawable.animate_sound_play);
}
}
