来自assest文件夹的Android画廊设置图像

Question

我想使用assest文件夹中的文件设置画廊的图像。

Answer 1

Try the following with an assets folder such as /assets/images/myimage.jpg

String imagePath =  "images/myimage.jpg"

Bitmap bmp = null;
try{
   InputStream is = getAssets().open(imagePath);        
   bmp = BitmapFactory.decodeStream(is);
}
catch(Exception exception)
{
    bmp = BitmapFactory.decodeResource(getResources(), R.drawable.icon_grey_box);
}
((ImageView)findViewById(R.id.myimage)).setScaleType(ImageView.ScaleType.CENTER_CROP);
((ImageView)findViewById(R.id.myimage)).setImageBitmap(bmp);

Just also thought, if your using GalleryView, and have a dataprovider then you might be able to format the image paths using

file://mnt/sdcard/imageassets/

I think there is also a way to access your apk assets folder, using a URI path, similar to

"android.resource://[package]/[res id]"

This explains it well.
