Android捕获home键

在Activity界面重写onAttachedToWindow方法

Java代码

 

@Override 
 public void onAttachedToWindow() {
  this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD); 
  super.onAttachedToWindow();
 }

 

 

switch (keyCode) {
     case KeyEvent.KEYCODE_HOME:
      Log.i(TAG,"KEYCODE_HOME");
      Toast.makeText(Test1Activity.this, "你按下了Home键", Toast.LENGTH_SHORT).show();
      return true;
