我使用了上下文

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

隐蔽位映射绘制在草图应用程序使用代码

    android.graphics.drawable.BitmapDrawable d = new android.graphics.drawable.BitmapDrawable(getResources(), bitmap);

尝试一下，它将位图类型的图像转换为可绘制

Drawable d = new BitmapDrawable(getResources(), bitmap);

如果你有一个位图图像，你想用它来绘图，比如

Bitmap contact_pic;    //a picture to show in drawable
drawable = new BitmapDrawable(contact_pic); 

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);

这是另一个:

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