这是另一个:

Drawable drawable = RoundedBitmapDrawableFactory.create(context.getResources(), bitmap);

这是另一个:

Drawable drawable = RoundedBitmapDrawableFactory.create(context.getResources(), bitmap);

我使用了上下文

//Convert bitmap to drawable
Drawable drawable = new BitmapDrawable(context.getResources(), bitmap);

1)位图到可绘制:

Drawable mDrawable = new BitmapDrawable(getResources(), bitmap);
// mImageView.setDrawable(mDrawable);

2)可绘制位图:

Bitmap mIcon = BitmapFactory.decodeResource(context.getResources(),R.drawable.icon_resource);
// mImageView.setImageBitmap(mIcon);

只要这样做:

private void setImg(ImageView mImageView, Bitmap bitmap) {

    Drawable mDrawable = new BitmapDrawable(getResources(), bitmap);
    mImageView.setDrawable(mDrawable);
}

官方位图绘制文档

这是一个关于如何将位图转换为可绘制的示例

Bitmap bitmap;  
//Convert bitmap to drawable
Drawable drawable = new BitmapDrawable(getResources(), bitmap);
imageView.setImageDrawable(drawable);
