当电话铃响时,我设法准备了一项活动.现在我需要知道如何取消这个活动,当我打电话或拒绝电话时.我是否打电话给EXTRA_STATE_IDLE？EXTRA_STATE_OFFHOOK？

有任何想法吗？

<receiver android:name=".IncomingBroadcastReceiver">                     
        <intent-filter>                                                   
            <action android:name="android.intent.action.PHONE_STATE"/>   
        </intent-filter>
    </receiver> 



public class IncomingBroadcastReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
    // If an incoming call arrives
    if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
    { //Did my work }
