问题描述
在menifest |keyboardHidden方向configChanges =:我使用的机器人。但它仍然刷新我的活动。这里是我的menifest活动标记。
<活动
机器人:名字=com.paksoft.people.MiActivity
机器人:标签=@字符串/ APP_NAME
机器人:configChanges =方向| keyboardHidden
机器人:screenOrientation =画像
机器人:windowSoftInputMode =adjustPan>
< /活性GT;
这有可能是 ACTION_IMAGE_CAPTURE
意图推出将推动你的活动内存不足。参见例如: Android startCamera给我空意图和......它毁了我的全局变量?
在这种情况下,的onCreate()您的活动
之前所谓的onActivityResult()
。你应该prepare你的活动重新初始化本身,可能使用的onSaveInstanceState(捆绑)
。
请注意,该决定是否关闭活动,或保持在后台,取决于超出你的控制系统的整体状态。
PS:的android:configChanges
因为活动不被破坏的系统响应方向开关(这不能用发生属性无关机器人:screenOrientation =肖像
),但由于系统资源被启动相机应用fullfill的 ACTION_IMAGE_CAPTURE
意图倒掉
I am using android:configChanges="orientation|keyboardHidden" in menifest. But still its refresh my activity. Here is my activity tag in menifest.
<activity
android:name="com.paksoft.people.MiActivity"
android:label="@string/app_name"
android:configChanges="orientation|keyboardHidden"
android:screenOrientation="portrait"
android:windowSoftInputMode="adjustPan" >
</activity>
It's possible that launching of ACTION_IMAGE_CAPTURE
intent will push your activity out of memory. See for example: Android startCamera gives me null Intent and ... does it destroy my global variable?
In this situation, onCreate()
of your activity is called before onActivityResult()
. You should prepare your activity to reinitialize itself, probably using onSaveInstanceState(Bundle)
.
Note that the decision whether to shut down the activity, or keep it in background, depends on the overall system state that is beyond your control.
PS: android:configChanges
attribute is irrelevant because the activity is destroyed not as response of the system to orientation switch (and this cannot happen with android:screenOrientation="portrait"
), but because the system resources are drained by launching the Camera app to fullfill the ACTION_IMAGE_CAPTURE
intent.
