How to create Drawable from resource
This code is deprecated:
Drawable drawable = getResources().getDrawable( R.drawable.icon );
Use this instead:
Drawable drawable = ContextCompat.getDrawable(getApplicationContext(),R.drawable.icon);
The getDrawable (int id)
method is deprecated as of API 22.
Instead you should use the getDrawable (int id, Resources.Theme theme)
for API 21+
Code would look something like this.
Drawable myDrawable;
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
myDrawable = context.getResources().getDrawable(id, context.getTheme());
} else {
myDrawable = context.getResources().getDrawable(id);
}
Your Activity should have the method getResources. Do:
Drawable myIcon = getResources().getDrawable( R.drawable.icon );
As of API version 21 this method is deprecated and can be replaced with:
Drawable myIcon = AppCompatResources.getDrawable(context, R.drawable.icon);
If you need to specify a custom theme, the following will apply it, but only if API is version 21 or greater:
Drawable myIcon = ResourcesCompat.getDrawable(getResources(), R.drawable.icon, theme);
I would just like to add that if you are getting "deprecated" message when using getDrawable(...) you should use the following method from the support library instead.
ContextCompat.getDrawable(getContext(),R.drawable.[name])
You do not have to use getResources() when using this method.
This is equivalent to doing something like
Drawable mDrawable;
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
mDrawable = ContextCompat.getDrawable(getContext(),R.drawable.[name]);
} else {
mDrawable = getResources().getDrawable(R.id.[name]);
}
This works on both pre and post Lollipop versions.
