Question

I am creating an application in which an alert dialog box pops up when i click on a button.Now when the phone is rotated this view gets disappears.Can anyone help me to retain this alert view even if phone is rotated?

Answer 1

The matter is that the system destroys the activity when a change in the configuration occurs.
See http://developer.android.com/reference/android/app/Activity.html#ConfigurationChanges

You have to add this to the activity declaration in the manifest:

android:configChanges=”orientation”

so it looks like

<activity android:label="@string/app_name" 
android:configChanges="orientation|keyboardHidden" 
android:name=".your.package">

So putting that in the configuration file avoids the system to destroy your activity. Instead it invokes the onConfigurationChanged(Configuration) method.

Or you can “force” your activity to be fixed on landscape or portrait mode and then the alertview will be retained but the view will be fixed whether the phone rotates or not .
It can be made by adding this to your manifest file (in your activity) :

android:screenOrientation=”portrait” or android:screenOrientation=”landscape”
