I'm currently making an android app in which I'd like the user to be able to change the background image.
I've got 3 images and a screen where I can choose a picture and a button for applying.
I can allow the user to see all images in the way I want, but I don't know how to set the selected image as app background.
What I want to do:
I want the user to click a button, which exports the selected image to "bakgrund.png" in "/res/drawable-mdpi" and replaces the current one. This would allow me to easily integrate the background switcher. Renaming of current files also works.
PS: My current background images are located in /res/drawable-mdpi named 1.png 2.png and 3.png.
Easiest way would be to call the
setBackgroundResource(image_id) method on the root layout. Like if you have a
LinearLayout which has
android:id="@+linear" as the root layout in the layout xml, then this code will help:-
LinearLayout linearLayout=(LinearLayout) findViewById(R.id.linear); linear.setBackgroundResource(R.drawable.1);//call this in the OnClickListener's OnClick Method
