电源按钮，在Android的音量按钮组合 [英] Combination of power button and volume up button in android

问题描述

像电源按钮和音量减小键的组合 - 采用手机的截图......同样，我试图访问音量和电源按钮长$ P $在我的应用程序pssed键，给一个快捷方式。这可能吗？

Like the combination of Power button and Volume down button - takes a screenshot of the phone... similarly I am trying to access volume up and power button long pressed keys in my app and give a shortcut. Is this possible?

我知道如何让两个按钮分别，但不能合并在同一时间的访问。

I know how to get the access of both buttons individually but not combined at the same time.

      @Override
      public boolean onKeyLongPress(int keyCode, KeyEvent event) {

    if (keyCode == KeyEvent.KEYCODE_POWER){
        Log.w("LongPress", "power LONG PRESS");
    }

                if (keyCode == KeyEvent.KEYCODE_VOLUME_UP){
        Log.w("LongPress", "Volume Up LONG PRESS");
    }

    return super.onKeyLongPress(keyCode, event);
   }

    @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_VOLUME_UP){
        event.startTracking();
        return true;
    }
    return super.onKeyDown(keyCode, event);
  }

如何获得组合在这里做'和;＆功放;不工作？

How to get the combination done here '&&' doesn't work?

推荐答案

我不明白，在机器人编程，但我看到它使用的Java类，那么试试这个

I don't understand programming under android, but I see it uses Java classes, so try this

public class BitKeys implements KeyListener {

    private BitSet keyBits = new BitSet(256);

    @Override
    public void keyPressed(final KeyEvent event) {
        int keyCode = event.getKeyCode();
        keyBits.set(keyCode);
    }

    @Override
    public void keyReleased(final KeyEvent event) {
        int keyCode = event.getKeyCode();
        keyBits.clear(keyCode);
    }

    @Override
    public void keyTyped(final KeyEvent event) {
        // don't care
    }

    public boolean isKeyPressed(final int keyCode) {
        return keyBits.get(keyCode);
    }

}

我发现这个在这里： <一href="http://stackoverflow.com/questions/11851155/handle-multiple-key-$p$psses-ignoring-repeated-key">handle多键presses忽略重复键

I found this here : handle multiple key presses ignoring repeated key
