Android的 - 建立一个通知,TaskStackBuilder.addParentStack不工作 [英] Android - Build a notification, TaskStackBuilder.addParentStack not working
问题描述
我试图启动从通知的活动,如Android的文档说明,但是当我打开通知,然后preSS后退按钮时,HomeActivity(父母)不开,而不是应用程序关闭。我究竟做错了什么?
意图resultIntent =新的意图(背景下,MatchActivity.class);;
resultIntent.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(上下文);
//添加背部栈的意图(而不是意图本身)
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
您需要添加父堆栈为你推出了它,而不是父母的活动。
替换:
stackBuilder.addParentStack(MainActivity.class);
与
stackBuilder.addParentStack(MatchActivity.class);
这假定您已经定义了父在清单(API 16 +):
<活动机器人:名称=。MatchActivity
机器人:parentActivityName =。MainActivity
... />
如果你在16 API开发,那么你必须定义父为:
<活动机器人:名称=。MatchActivity>
&所述;元数据
机器人:名称=android.support.PARENT_ACTIVITY
MainActivity:机器人值= />
< /活性GT;
I'm trying to launch an activity from a notification like the Android docs explain, but when I open the notification and then press the back button, the HomeActivity (parent) doesn't open, instead the application closes. What am I doing wrong?
Intent resultIntent = new Intent(context, MatchActivity.class);;
resultIntent.setFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
You need to add the parent stack for the activity you're launching, not the parent of it.
Replace:
stackBuilder.addParentStack(MainActivity.class);
with:
stackBuilder.addParentStack( MatchActivity.class );
This assumes that you've defined the parent in your Manifest (API 16+):
<activity android:name=".MatchActivity"
android:parentActivityName=".MainActivity"
... />
If you're developing for under API 16, then you have to define the parent as:
<activity android:name=".MatchActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity" />
</activity>
