Question

我正在制作一个媒体播放器, 需要使用“ 搜索棒” 来设置平衡效果, 使用“ 回收棒 ” 、 “ 可怕的 ” 、 “ 洛克 ” 、 “ Pop ” 、 “ Medium ” 。我有一个链接, 用于做这个操作的一些 NDK 库。是否有任何 Java 图书馆可以这样做, 请解释这样做的逻辑。

 @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.equalizertab);


      f
   }
  } else {
   try {
    ((GlobalState) getApplicationContext())
      .resetEQ();
   } catch (RemoteException re) {
    // TODO:
   }
  }
 }
});

以下的日志标记 :
