Change Remoteview Imageview Background

I have some remoteView with ImageViews, and I need to change the 'android:background' programmatically. I know how to change the 'android:src' with: remoteView.setImageViewResource

Solution 1:

You can use public void setInt (int viewId, String methodName, int value) method.

remoteView.setInt(R.id.viewid, "setBackgroundResource", R.color.your_color)

Solution 2:

Use setBackgroundResource(int).

Also, here is something you may take note of. When you look at Android documentation, if there is an xml element for a View that you can change, it normally points to the method to make the change at runtime.

Solution 3:

The jerry-rig way

I think you could do it using the jerry-rig way doing a second layout with the new background, then you create your remoteView using this new layout, like this:

• RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget1);
• RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget2);

after all, a layout isn't so expensive.
