ResourcesCompat.getDrawable() vs AppCompatResources.getDrawable()

Question

I\'m a bit confused with these two APIs.

ResourcesCompat.getDrawable(Resources res, int id, Resources.Theme theme)

Return a drawable

Answer 1

API 19+ workaround

package com.example;

import android.content.Context;
import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.view.View;

import androidx.annotation.DrawableRes;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.appcompat.content.res.AppCompatResources;
import androidx.core.content.ContextCompat;
import androidx.vectordrawable.graphics.drawable.VectorDrawableCompat;

/**

 */
public class AppDrawableCompat {

    public static Drawable getDrawable(@NonNull Context context, @DrawableRes int resId) {
        try {
            return AppCompatResources.getDrawable(context, resId);
        } catch (Resources.NotFoundException e1) {
            try {
                return ContextCompat.getDrawable(context, resId);
            } catch (Resources.NotFoundException e2) {
                return VectorDrawableCompat.create(context.getResources(), resId, context.getTheme());
            }
        }
    }

    @Nullable
    public static Drawable findDrawable (@NonNull Context context, @DrawableRes int resId) {
        try {
            return getDrawable(context, resId);
        } catch (Resources.NotFoundException e) {
            return null;
        }
    }

    public static void setViewBackgroundDrawable(@NonNull View view, @NonNull Context context, @DrawableRes int resId) {
        Drawable drawable = findDrawable(context, resId);
        if (drawable != null) {
            view.setBackground(drawable);
        }
    }
}

Using example (MainActivity#onCreate)

ImageView icon = findViewById(R.id.icon);
AppDrawableCompat.setViewBackgroundDrawable(icon, this, R.drawable.bg_icon);
