Android Activity as a dialog
-

Question
I have an Activity named whereActity
which has child dialogs as well. Now, I want to display this activity as a dialog for another activity.
How can I do that?
Solution
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.
OTHER TIPS
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">
1 - You can use the same activity as both dialog and full screen, dynamically:
Call setTheme(android.R.style.Theme_Dialog)
before calling setContentView(...)
and super.oncreate()
in your Activity.
2 - If you don't plan to change the activity theme style you can use
<activity android:theme="@android:style/Theme.Dialog" />
(as mentioned by @faisal khan)
If you need Appcompat Version
style.xml
<!-- Base application theme. -->
<style name="AppDialogTheme" parent="Theme.AppCompat.Light.Dialog">
<!-- Customize your theme here. -->
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
</style>
yourmanifest.xml
<activity
android:name=".MyActivity"
android:label="@string/title"
android:theme="@style/AppDialogTheme">
</activity>
If your activity is being rendered as a dialog, simply add a button to your activity's xml,
<Button
android:id="@+id/close_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Dismiss" />
Then attach a click listener in your Activity's Java code. In the listener, simply call finish()
Button close_button = (Button) findViewById(R.id.close_button);
close_button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
That should dismiss your dialog, returning you to the calling activity.
If you want to remove activity header & provide a custom view for the dialog add the following to the activity block of you manifest
android:theme="@style/Base.Theme.AppCompat.Dialog"
and design your activity_layout with your desired view
Set the theme in your android manifest file.
<activity android:name=".LoginActivity"
android:theme="@android:style/Theme.Dialog"/>
And set the dialog state on touch to finish.
this.setFinishOnTouchOutside(false);
