Android getResources().getDrawable() deprecated API 22

Question

With new android API 22 getResources().getDrawable() is now deprecated. Now the best approach is to use only getDrawable().

What changed? <

Answer 1

Build.VERSION_CODES.LOLLIPOP should now be changed to BuildVersionCodes.Lollipop i.e:

if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop) {
    this.Control.Background = this.Resources.GetDrawable(Resource.Drawable.AddBorder, Context.Theme);
} else {
    this.Control.Background = this.Resources.GetDrawable(Resource.Drawable.AddBorder);
}

Answer 2

Just an example of how I fixed the problem in an array to load a listView, hope it helps.

 mItems = new ArrayList<ListViewItem>();
//    Resources resources = getResources();

//    mItems.add(new ListViewItem(resources.getDrawable(R.drawable.az_lgo), getString(R.string.st_az), getString(R.string.all_nums)));
//    mItems.add(new ListViewItem(resources.getDrawable(R.drawable.ca_lgo), getString(R.string.st_ca), getString(R.string.all_nums)));
//    mItems.add(new ListViewItem(resources.getDrawable(R.drawable.co_lgo), getString(R.string.st_co), getString(R.string.all_nums)));
    mItems.add(new ListViewItem(ResourcesCompat.getDrawable(getResources(), R.drawable.az_lgo, null), getString(R.string.st_az), getString(R.string.all_nums)));
    mItems.add(new ListViewItem(ResourcesCompat.getDrawable(getResources(), R.drawable.ca_lgo, null), getString(R.string.st_ca), getString(R.string.all_nums)));
    mItems.add(new ListViewItem(ResourcesCompat.getDrawable(getResources(), R.drawable.co_lgo, null), getString(R.string.st_co), getString(R.string.all_nums)));

Answer 3

In Kotlin you can use extension

fun Context.getMyDrawable(id : Int) : Drawable?{

    return  ContextCompat.getDrawable(this, id)
}

then use like

context.getMyDrawable(R.drawable.my_icon)

Answer 4

getResources().getDrawable() was deprecated in API level 22. Now we must add the theme:

getDrawable (int id, Resources.Theme theme) (Added in API level 21)

This is an example:

myImgView.setImageDrawable(getResources().getDrawable(R.drawable.myimage, getApplicationContext().getTheme()));

This is an example how to validate for later versions:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { //>= API 21
     myImgView.setImageDrawable(getResources().getDrawable(R.drawable.myimage, getApplicationContext().getTheme()));
   } else { 
     myImgView.setImageDrawable(getResources().getDrawable(R.drawable.myimage));
}

Answer 5

Now you need to implement like this

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { //>= API 21
        //
    } else {
        //
    }

Following single line of code is enough, everything will take care by ContextCompat.getDrawable

ContextCompat.getDrawable(this, R.drawable.your_drawable_file)

Answer 6

If you are targeting SDK > 21 (lollipop or 5.0) use

context.getDrawable(R.drawable.your_drawable_name)
