How can I show some drawable programmatically created using ImageLoader.displayImage()?
According to documentation:
String imageUri = "drawable://" + R.drawable.image; // from drawables (only images, non-9patch)
This only works using resource drawables
EDIT: I want to do something like:
Drawable drawable = ...
myImageView.setImageDrawable(drawable); // Using ImageLoader
if(url != null && url != "")
loader.displayImage(URLProtocol.parseURL(url, false), image)
else
image.setImageResource(R.drawable.yourdrawable)
If you want to display a local drawable instead of a URL image with ImageLoad plugin, you can simply check if your URL exists and, if not, you can simply set the drawable as the image fir the ImageView.
The best solution would be if you create a Bitmap from that Drawable and then save it to a File.
Use this to get the Bitmap from Drawable:
Drawable yourDrawable;
Bitmap bitmap = ((BitmapDrawable)yourDrawable).getBitmap();
Create a File from Bitmap:
//create a file to write bitmap data
File f = File(context.getCacheDir(), filename);
f.createNewFile();
//Convert bitmap to byte array
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0 /*ignored for PNG*/, bos);
byte[] bitmapdata = bos.toByteArray();
//write the bytes in file
FileOutputStream fos = new FileOutputStream(f);
fos.write(bitmapdata);
fos.flush();
fos.close();
Dont forget manifest permission:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
After you do this you can use Universal Image Loader to load the file to your ImageView
