Android-based R. drawable. *** generate Drawa and Bitmap

Files in R. drawable. *** are commonly used, but sometimes there is no direct way to obtain images through the R file. At this time, we need to directly convert them.

The following provides four methods for your reference:

1,

Resources resources = mContext. getResources ();
Drawable drawable = resources. getDrawable (R. drawable .***);

2,

Resources resources = this. getContext (). getResources ();
Inputstream is = resources. openRawResource (R. drawable ***);
BitmapDrawable BMP draw = new BitmapDrawable (is );
Bitmap bmp = bmp draw. getBitmap ();

3,

Resources resources = this. getContext (). getResources ();

Bitmap bmp = BitmapFactory. decodeResource (resources, R. drawable .***);

Bitmap newb = Bitmap. createBitmap (300,300, Config. ARGB_8888 );

4,

InputStream is = getResources (). openRawResource (R. drawable .***);

Bitmap mBitmap = BitmapFactory. decodeStream (is );
