我想使用音量按钮在我的Andr​​oid应用程序别的东西。海豚浏览器做到这一点，我说。任何人都知道怎么样？

I'd like to use the volume buttons for something else in my Android application. The Dolphin browser does this I am told. Anyone know how?

推荐答案

我想它看起来是这样的：

I imagine it looks something like this:

public boolean onKeyDown(int keyCode, KeyEvent event) 
{ 
   if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN || keyCode == KeyEvent.KEYCODE_VOLUME_UP) { 
       // Do your thing 
       return true;
   } else {
       return super.onKeyDown(keyCode, event); 
   }
}
