[英]resuming activity in Android using Service
I have a mainActivity
. 我有一个
mainActivity
。
When starts, it starts a service and bonds it. 启动时,它将启动服务并将其绑定。
There is a timer which will send the mainActivity
(this) to back after X seconds, while the service keep running and listening, i use moveTaskToBack (true)
. 有一个计时器,它将在X秒后将
mainActivity
(this)发送回去,同时该服务保持运行和侦听,我使用moveTaskToBack (true)
。
When the service listener triggered, the service starts the activity, but instead of the activity to be called through onResume()
(since it was sent to back) its called through onCreate()
, to call the activity currently i use : 当服务侦听器触发时,服务将启动活动,但不是通过
onResume()
调用活动(因为它已发送回),而是通过onCreate()
调用了该活动,以调用当前使用的活动:
Intent dialogIntent = new Intent(getBaseContext(), MainActivity.class);
dialogIntent.addFlags(Intent.FLAG_FROM_BACKGROUND);
getApplication().startActivity(dialogIntent);
Which explains why the activity is created all over again. 这说明了为什么要重新创建活动。 I tried using
FLAG_ACTIVITY_REORDER_TO_FRONT
but got an exception. 我尝试使用
FLAG_ACTIVITY_REORDER_TO_FRONT
但是遇到了异常。
add this attribute in activity of AndroidManifest.xml android:launchMode="singleInstance"
in AndroidManitest.xml 在AndroidManifest.xml的活动中将此属性添加到AndroidManitest.xml中的
android:launchMode="singleInstance"
AndroidMenifest.xml AndroidMenifest.xml
<application>
<activity
android:launchMode="singleInstance">
</activity>
</application>
