创建一个广播接收器

class InnerRecevier extends BroadcastReceiver {
        final String SYSTEM_DIALOG_REASON_KEY = "reason";
        final String SYSTEM_DIALOG_REASON_RECENT_APPS = "recentapps";
        final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";

        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (Intent.ACTION_CLOSE_SYSTEM_DIALOGS.equals(action)) {
                String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);
                if (reason != null) {
                    if (reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) {
                        Toast.makeText(MainActivity.this, "Home键被监听", Toast.LENGTH_SHORT).show();
                    } else if (reason.equals(SYSTEM_DIALOG_REASON_RECENT_APPS)) {
                        Toast.makeText(MainActivity.this, "多任务键被监听", Toast.LENGTH_SHORT).show();
                    }
                }
            }
        }
    }

在Activity中的onCreate()方法中注册广播

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //创建广播
    InnerRecevier innerReceiver = new InnerRecevier();
    //动态注册广播
    IntentFilter intentFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
    //启动广播
    registerReceiver(innerReceiver, intentFilter);
}

上面代码即可实现对home键、多任务键进行监听，但是无法屏蔽系统的行为
