Android getResources().getDrawable() deprecated API 22

问题

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

What changed?

回答1:

You have some options to handle this deprecation the right (and future proof) way, depending on which kind of drawable you are loading:

---

A) drawables with theme attributes

ContextCompat.getDrawable(getActivity(), R.drawable.name);

You'll obtain a styled Drawable as your Activity theme instructs. This is probably what you need.

---

B) drawables without theme attributes

ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

You'll get your unstyled drawable the old way. Please note: ResourcesCompat.getDrawable() is not deprecated!

---

EXTRA) drawables with theme attributes from another theme

ResourcesCompat.getDrawable(getResources(), R.drawable.name, anotherTheme);

You should use the following code from the support library instead:

ContextCompat.getDrawable(context, R.drawable.***)

Using this method is equivalent to calling:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    return resources.getDrawable(id, context.getTheme());
} else {
    return resources.getDrawable(id);
}

As of API 21, you should use the getDrawable(int, Theme) method instead of getDrawable(int), as it allows you to fetch a drawable object associated with a particular resource ID for the given screen density/theme. Calling the deprecated getDrawable(int) method is equivalent to calling getDrawable(int, null).

Replace this line : getResources().getDrawable(R.drawable.your_drawable)

with ResourcesCompat.getDrawable(getResources(), R.drawable.your_drawable, null)

EDIT

ResourcesCompat is also deprecated now. But you can use this:

ContextCompat.getDrawable(this, R.drawable.your_drawable) (Here this is the context)

for more details follow this link: ContextCompat

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));
}

回答5:

You can use

ContextCompat.getDrawable(getApplicationContext(),R.drawable.example);

that's work for me

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)));

Try this:

public static List<ProductActivity> getCatalog(Resources res){
    if(catalog == null) {
        catalog.add(new Product("Dead or Alive", res
                .getDrawable(R.drawable.product_salmon),
                "Dead or Alive by Tom Clancy with Grant Blackwood", 29.99));
        catalog.add(new Product("Switch", res
                .getDrawable(R.drawable.switchbook),
                "Switch by Chip Heath and Dan Heath", 24.99));
        catalog.add(new Product("Watchmen", res
                .getDrawable(R.drawable.watchmen),
                "Watchmen by Alan Moore and Dave Gibbons", 14.99));
    }
}

回答8:

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

context.getDrawable(R.drawable.your_drawable_name)

See docs

回答9:

en api level 14

marker.setIcon(ResourcesCompat.getDrawable(getResources(), R.drawable.miubicacion, null));

回答10:

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)

回答11:

getDrawable(int drawable) is deprecated in API level 22. For reference see this link.

Now to resolve this problem we have to pass a new constructer along with id like as :-

getDrawable(int id, Resources.Theme theme)

For Solutions Do like this:-

In Java:-

ContextCompat.getDrawable(getActivity(), R.drawable.name);   

or

 imgProfile.setImageDrawable(getResources().getDrawable(R.drawable.img_prof, getApplicationContext().getTheme()));

In Kotlin :-

rel_week.background=ContextCompat.getDrawable(this.requireContext(), R.color.colorWhite)

or

 rel_day.background=resources.getDrawable(R.drawable.ic_home, context?.theme)

Hope this will help you.Thanks.

回答12:

For some who still got this issue to solve even after applying the suggestion of this thread(i used to be one like that) add this line on your Application class, onCreate() method

AppCompatDelegate.setCompatVectorFromResourcesEnabled(true)

As suggested here and here sometimes this is required to access vectors from resources especially when you're dealing with menu items, etc

回答13:

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)

回答14:

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);
}
