如果您点击通知上的快速回复按钮,我正在尝试创建一个小窗口打开.在WhatsApp中,它打开了一个半屏幕窗口.目前我正在做以下事情：
我打开一个名为NotificationActivity的活动.在AndroidManifest.xml中,我将活动注册为
<activity
android:name=".activity.NotificationActivity"
android:theme="@style/Theme.AppCompat.Light.Dialog.custom"
android:label="@string/title_activity_notification"
android:screenorientation="portrait"
android:windowSoftInputMode="adjustResize|stateHidden" />
这是风格：
<style name="Theme.AppCompat.Light.Dialog.custom">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
</style>
现在,当应用程序完全关闭(关闭然后滑开),它的工作完美.
但是,如果应用程序被最小化,当有人点击回复按钮时,它会打开应用程序,然后在其上粘贴NotificationActivity.如何防止应用程序在后台打开,只有半屏幕通知活动被打开.
非常感谢
编辑：我在想,也许xml文件是相关的？

还不知道这是否相关,但这里是如何创建回复
String KEY_TEXT_REPLY = "key_text_reply";
String replyLabel = "Type here";
Intent intent = new Intent(context,NotificationActivity.class);
intent.putExtra(Constants.REQUEST_ID,messageData.taskid);
intent.putExtra(Constants.JUDE_ID,messageData.from);
intent.putExtra(Constants.FROM,Constants.NOTIFICATION);
PendingIntent pendingIntent = PendingIntent.getActivity(
context,intent,PendingIntent.FLAG_UPDATE_CURRENT);
RemoteInput remoteInput = new RemoteInput.Builder(KEY_TEXT_REPLY)
.setLabel(replyLabel)
.build();
NotificationCompat.Action replyAction = new NotificationCompat.Action.Builder(
R.drawable.send_button,"Reply",pendingIntent)
.addRemoteInput(remoteInput)
.build();
builder.addAction(replyAction);
解决方法
要实现你想要的,你需要使用属性
android:launchMode的值为singleInstance：
Same as
"singleTask",except that the system doesn’t launch any other
activities into the task holding the instance. The activity is always
the single and only member of its task.
您还应该添加android：excludeFromrecents =“true”,以将您的活动从最近使用的应用程序列表中排除,如documentation所述：
Whether or not the task initiated by this activity should be excluded
from the list of recently used applications,the overview screen. That
is,when this activity is the root activity of a new task,this
attribute determines whether the task should not appear in the list of
recent apps. Set “true” if the task should be excluded from the list;
set “false” if it should be included. The default value is “false”.
总而言之,您需要更改您的AndroidManifest.xml,如下所示：
<activity
android:name=".activity.NotificationActivity"
android:theme="@style/Theme.AppCompat.Light.Dialog.custom"
android:label="@string/title_activity_notification"
android:screenorientation="portrait"
android:windowSoftInputMode="adjustResize|stateHidden"
android:launchMode="singleInstance"
android:excludeFromrecents="true" />
