Android中Home键及返回键的屏蔽

1.只屏蔽Home键，只需在Activity中重写onAttachedToWindow()方法

public static final int FLAG_HOMEKEY_DISPATCHED = 0x80000000;

  @Overridepublic void onAttachedToWindow() {    
    //关键：在onAttachedToWindow中设置FLAG_HOMEKEY_DISPATCHED                 
    this.getWindow().addFlags(FLAG_HOMEKEY_DISPATCHED);    
    super.onAttachedToWindow();}

2.只屏蔽返回键，只需在Activity中重写onBackPressed()方法

 public void onBackPressed() {
//        super.onBackPressed();
//        屏蔽掉返回按键
 }
