应用如何在Android活动中临时显示全屏动画？

Question

Similar questions have been asked before, but I couldn't find an answer to how to make one element full screen. I would like to temporarily display a full-screen animation in my Android app without moving to a new Activity. The app has an ImageView for the animation and I show the animation with:

image.setBackground(animation);

and make it "go away" with:

image.setBackground(null);

For the ImageView, both android:layout_width and android:layout_height are set to "match_parent". It works, but of course the animation doesn't include the title bar at the top or the icons at the bottom. I even tried setting the layout_marginTop and layout_marginBottom to negative values, but I know that can't be the best solution for every device or orientation which may run this app.

How can I change the size of the ImageView to full screen so I can show it as needed, or is there a better way to do what I want?

Answer 1

Duplicate of Fullscreen Activity in Android? .

Just set the right flags and dismiss the activity when it's finished its animation.

Answer 2

Your ImageView is stuck inside the bounds of your Activity. And I don't think there is a way for you to change your Activity to be full screen sometimes but not others.

If you want your Activity to be fullscreen always you can set the theme in the manifest like this:

<activity
    android:name="com.your.package.name.YourActivity"
    android:label="@string/app_name" 
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
</activity>

Answer 3

Combine both answers. Create a new activity to play your animation and set the theme of your animation activity to fullscreen.
