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);

Bitmap bitmap;

Drawable drawable = new BitmapDrawable(getResources(), bitmap);
imageView.setImageDrawable(drawable);

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);

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);

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); 

只要这样做:

private void setImg(ImageView mImageView, Bitmap bitmap) {

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