从Uri检索可绘制资源

Question

我以这种方式将可绘制资源路径存储在Uri中:

Uri uri = Uri.parse("android.resource://my_app_package/drawable/drawable_name");

如何获得uri引用的Drawable？

我不想把它放在ImageView中,只需检索Drawable(或Bitmap)对象.

Answer 1

getContentResolver cr object 然后打电话:

is = cr.openInputStream(uri) 

最后打电话给:

Drawable.createFromStream(InputStream is, String srcName)

...这是一个实际的工作代码示例,您可以自己查看:

try {
    InputStream inputStream = getContentResolver().openInputStream(yourUri);
    yourDrawable = Drawable.createFromStream(inputStream, yourUri.toString() );
} catch (FileNotFoundException e) {
    yourDrawable = getResources().getDrawable(R.drawable.default_image);
}
