Android实现对HOME键的捕获和屏蔽

1.1. 在AndroidManifest.xml中加上权限，禁止HOME键。

<uses-permission android:name="android.permission.DISABLE_KEYGUARD"/>

public static final int FLAG_HOMEKEY_DISPATCHED = 0x80000000;

public void onAttachedToWindow(){  
    getWindow().setFlags(FLAG_HOMEKEY_DISPATCHED,FLAG_HOMEKEY_DISPATCHED); 

super.onAttachedToWindow(); 

}

public boolean dispatchKeyEvent(KeyEvent e) {

        if (e.getKeyCode() == KeyEvent.KEYCODE_HOME)

        return true;

    }
