对于新的android API 22,getResources().getDrawable()现在已被弃用。现在最好的方法是只使用getDrawable()。

什么改变了?

对于一些即使在应用了这个线程的建议(我以前也是这样的)之后仍然需要解决这个问题的人,请在Application类上添加这行,onCreate()方法

AppCompatDelegate.setComptVectorFromResourcesEnabled(true)

正如这里和这里所建议的,有时需要从资源中访问向量,尤其是在处理菜单项等时

如果您需要从其他SDK 23及以上版本的应用程序中提取

PackageManager manager = getApplicationContext().getPackageManager();
Resources resources = null;
try {
    resources = manager.getResourcesForApplication("com.anyapp");
    } 
catch (PackageManager.NameNotFoundException e) {
   e.printStackTrace();
   }
assert resources != null;
Drawable notiIcon = ResourcesCompat.getDrawable(resources, current.iconId/* drawable resource id */, null);

getResources().getDrawable()在API级别22中被弃用。现在我们必须添加主题:

getDrawable(int id,Resources.Theme主题)(在API级别21中添加)

这是一个示例:

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

以下是如何验证更高版本的示例:

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));
}

这只是我如何在数组中修复问题以加载listView的一个示例,希望它有所帮助。

 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)));

替换此行:getResources().getDrawable(R.drawable.your_drawable)

使用ResourcesCompat.getDrawable(getResources(),R.draable.your_drawable,null)

EDIT

ResourcesCompat现在也被弃用。但您可以使用此选项:

ContextCompat.getDrawable(this,R.drawable.your_drawable)(这里是上下文)

试试看:

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));
    }
}
