IMAGE 我有代碼。這工作正常，並關閉通知。但是當我點擊「解除」按鈕時，它會打開應用程序並關閉對話框。這對我不是必需的。實際上，我想要的是，在不打開任何活動的情況下單擊「DISMISS」按鈕後關閉通知對話框。如何在點擊退出按鈕後關閉通知對話框，無需調用任何活動
MainActivity.java
public class MainActivity extends Activity{
static int numMessages = 0;
Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.notificationmain);
context = getApplicationContext();
Button bcustomnotifyaction = (Button) findViewById(R.id.customnotificationaction);
bcustomnotifyaction.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
CustomNotificationAction();
}
});
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void CustomNotificationAction() {
// Set Notification Title
String strtitle = "You Got New Notification.";
// Set Notification Text
String strtext ="Hi,How are You?";
// Open NotificationView Class on Notification Click
Intent intent = new Intent(this, NotificationView.class);
// Send data to NotificationView Class
intent.putExtra("title", strtitle);
intent.putExtra("text", strtext);
// Open NotificationView.java Activity
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
int notificationId = new Random().nextInt(); // just use a counter in some util class...
PendingIntent dismissIntent = NotificationActivity.getDismissIntent(notificationId, getApplicationContext());
//Create Notification using NotificationCompat.Builder
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
// Set Icon
.setSmallIcon(R.drawable.logosmall)
// Set Ticker Message
.setTicker(strtitle)
// Set Title
.setContentTitle(strtitle)
// Set Text
.setContentText(strtext)
// Add an Action Button below Notification
.addAction(android.R.drawable.ic_menu_close_clear_cancel, "Dismiss", dismissIntent)
.addAction(android.R.drawable.ic_menu_info_details, "Info", pIntent)
// Set PendingIntent into Notification
.setContentIntent(pIntent)
// showing action button on notification
.setPriority(Notification.PRIORITY_MAX)
.setWhen(0)
/* Increase notification number every time a new notification arrives */
.setNumber(++numMessages)
// Dismiss Notification
.setAutoCancel(true);
// Create Notification Manager
NotificationManager notificationmanager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// Build Notification with Notification Manager
notificationmanager.notify(0, builder.build());
}
}

String text;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.notificationview);
// Create Notification Manager
NotificationManager notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Dismiss Notification
notificationmanager.cancel(0);
// Retrive the data from MainActivity.java
Intent i = getIntent();
title = i.getStringExtra("title");
text = i.getStringExtra("text");
// Locate the TextView
txttitle = (TextView) findViewById(R.id.title);
txttext = (TextView) findViewById(R.id.text);
// Set the data into TextView
txttitle.setText(title);
txttext.setText(text);
}
}
notificationview.xml
NotificationActivity.java
public class NotificationActivity extends Activity {
public static final String NOTIFICATION_ID = "NOTIFICATION_ID";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.cancel(0);
finish(); // since finish() is called in onCreate(), onDestroy() will be called immediately
}
public static PendingIntent getDismissIntent(int notificationId, Context context) {
Intent intent = new Intent(context, NotificationActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.putExtra(NOTIFICATION_ID, notificationId);
PendingIntent dismissIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
return dismissIntent;
}
}
解決方案：
我通過廣播接收器得到了我的解決方案。
CODE我改變： 我在加入此代碼MainActivity.java CustomNotificationAction（）。
//Create an Intent for the BroadcastReceiver
Intent buttonIntent = new Intent(context, ButtonReceiver.class);
//Create the PendingIntent
PendingIntent btPendingIntent = PendingIntent.getBroadcast(context, 0, buttonIntent,0);
，改變了這條線從
.addAction(android.R.drawable.ic_menu_close_clear_cancel, "Dismiss", dismissIntent)
要
.addAction(android.R.drawable.ic_menu_close_clear_cancel, "Dismiss", btPendingIntent)
並添加一個Java文件
ButtonReceiver。java的
public class ButtonReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Notification Dialog Closed",
Toast.LENGTH_LONG).show();
Log.d("Notification:","Notification Dialog Closed");
NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancel(0);
PendingIntent resultPendingIntent = PendingIntent.getActivity(context, 0, new Intent(), 0);
NotificationCompat.Builder mb = new NotificationCompat.Builder(context);
mb.setContentIntent(resultPendingIntent);
}
}
而且註冊廣播在Mainfest文件
<receiver android:name=".ButtonReceiver"/>
我的問題解決了:)

我有2個操作按鈕「解僱」和「信息」。對於信息我會打開一個活動，顯示一些消息，「解僱」按鈕我想通知對話框將解僱，而不打開活動：/ – lisha
