如何在不关闭先前活动的情况下从通知中打开对话框样式的活动? [英] How to open dialog styled activity from notification without previous activity closing?

问题描述

1. 我有一个具有对话框样式的活动，因此它在上一个活动的顶部以可视方式打开.
2. 我有一条通知会打开此活动，如下所示:

Intent intent = new Intent(this, CalcActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
((NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE)).notify(0, builder.build());

问题在于，当用户点击我的通知时，先前的可见活动关闭，出现主屏幕，并且我的对话框显示在主屏幕顶部.如何防止关闭先前的活动?请注意，以前的活动可能不是来自我的应用.

The problem is that when user taps my notification, previous visible activity closes, home screen appears and my dialog is displayed on top of home screen. How to prevent closing of previous activity? Please note that previous activity might not come from my app.

推荐答案

使用Intent如下:

Use Intent as below :

Intent intent = new Intent(this,MainActivity.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

并在AndroidManifest.xml中注册活动并将主题用作dialog:

and in AndroidManifest.xml register activity and use theme as dialog:

<activity android:name=".MainActivity" android:theme="@style/Theme.AppCompat.Light.Dialog"/>
