Sounds like you want to use BitmapDrawable
听起来你想使用 BitmapDrawable
From the documentation:
从文档：
A
Drawablethat wraps a bitmap and can be tiled, stretched, or aligned. You can create aBitmapDrawablefrom a file path, an input stream, through XML inflation, or from aBitmapobject.
一个
Drawable一个包装了位图，可以平铺，拉伸，或对齐。您可以BitmapDrawable从文件路径、输入流、通过 XML 膨胀或从Bitmap对象创建 。

Try this it converts a Bitmaptype image to Drawable
试试这个它将Bitmap类型图像转换为Drawable
Drawable d = new BitmapDrawable(getResources(), bitmap);

Having seen a large amount of issues with bitmaps incorrectly scaling when converted to a BitmapDrawable, the general way to convert should be:
在转换为 a 时BitmapDrawable，看到大量位图缩放不正确的问题，转换的一般方法应该是：
Drawable d = new BitmapDrawable(getResources(), bitmap);
Without the Resources reference, the bitmapmay not render properly, even when scaled correctly. There are numerous questions on here which would be solved simply by using this method rather than a straight call with only the bitmapargument.
如果没有Resources reference，则bitmap可能无法正常正确缩放时渲染，甚至。这里有许多问题可以通过使用此方法而不是仅使用bitmap参数的直接调用来解决。

If you have a bitmap image and you want to use it in drawable, like
如果你有一个位图图像并且你想在 drawable 中使用它，比如
Bitmap contact_pic; //a picture to show in drawable
drawable = new BitmapDrawable(contact_pic);

Just do this:
只需这样做：
private void setImg(ImageView mImageView, Bitmap bitmap) {
Drawable mDrawable = new BitmapDrawable(getResources(), bitmap);
mImageView.setDrawable(mDrawable);
}

1) bitmap to Drawable :
1) 位图到 Drawable ：
Drawable mDrawable = new BitmapDrawable(getResources(), bitmap);
// mImageView.setDrawable(mDrawable);
2) drawable to Bitmap :
2）可绘制到位图：
Bitmap mIcon = BitmapFactory.decodeResource(context.getResources(),R.drawable.icon_resource);
// mImageView.setImageBitmap(mIcon);

here's another one:
这是另一个：
Drawable drawable = RoundedBitmapDrawableFactory.create(context.getResources(), bitmap);

covert bit map to drawable in sketchware app using code
使用代码将位图隐藏到可在 Sketchware 应用程序中绘制
android.graphics.drawable.BitmapDrawable d = new android.graphics.drawable.BitmapDrawable(getResources(), bitmap);
