從活動開始BroadCastReceiver

Question

我想從Activity開始BroadcastReceiver。我怎樣才能做到這一點？

Answer 1

定義你的廣播接收器：

private final BroadcastReceiver    receiver 
    = new BroadcastReceiver() { 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     // Do something 
    } 
}; 

填寫您的接收器中的onResume：

@Override 
protected void onResume() { 
    super.onResume(); 

    IntentFilter filter = new IntentFilter(); 
    filter.addAction("SOME_ACTION"); 
    registerReceiver(receiver, filter); 
} 

註銷接收器的onPause：

@Override 
protected void onPause() { 
    super.onPause(); 

    unregisterReceiver(receiver); 
}
