Android Activity as a dialog
To start activity as dialog I defined it like this in AndroidManifest.xml
:
<activity android:theme="@android:style/Theme.Dialog" />
Use this property inside your activity
tag to avoid that your Dialog appears in the recently used apps list
android:excludeFromRecents="true"
If you want to stop your dialog / activity from being destroyed when the user clicks outside of the dialog:
After setContentView()
in your Activity
use:
this.setFinishOnTouchOutside(false);
Now when I call startActivity()
it displays as a dialog, with the previous activity shown when the user presses the back button.
Note that if you are using ActionBarActivity
(or AppCompat theme), you'll need to use @style/Theme.AppCompat.Dialog
instead.
Use this code so that the dialog activity won't be closed when the user touches outside the dialog box:
this.setFinishOnTouchOutside(false);
requires API level 11
You can define this style in values/styles.xml to perform a more former Splash :
<style name="Theme.UserDialog" parent="android:style/Theme.Dialog"> <item name="android:windowFrame">@null</item> <item name="android:windowIsFloating">true</item> <item name="android:windowIsTranslucent">true</item> <item name="android:windowNoTitle">true</item> <item name="android:background">@android:color/transparent</item> <item name="android:windowBackground">@drawable/trans</item> </style>
And use it AndroidManifest.xml:
<activity android:name=".SplashActivity" android:configChanges="orientation" android:screenOrientation="sensor" android:theme="@style/Theme.UserDialog">
