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(int viewId, int srcId);
And it works fine, but how do I change the “android:background”?
You can use
public void setInt (int viewId, String methodName, int value) method.
remoteView.setInt(R.id.viewid, "setBackgroundResource", R.color.your_color)
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.
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.
