Can specific point method under toDrawable

Drawable landlord static method createFromXml () try:
public static Drawable createFromXml (Resources r, XmlPullParser parser)

The following is a simple example code, the principle is to be read out to the xml file FileReader object, and then used as an input stream to XmlPullParser object.

 XmlPullParser xmlParser = null; 
File file = new File ("your storage xml file path"); 

FileReader fileReader = null; 
try {
fileReader = new FileReader (file); 
xmlParser = Xml.newPullParser (); 
xmlParser.setInput (fileReader); 
Drawable drawable = Drawable.createFromXml (getResources (), xmlParser); 

} Catch (FileNotFoundException e) {

} Catch (Exception e) {

} Finally {
try {
if (fileReader! = null) {
fileReader.close (); 
} 
} Catch (IOException e) {
} 
}

You downloaded files into byte, then by byte then converted into bitmap drawable

Should not be an external address to use it

Drawable.createFromXml method should be used for internal xml, use the drawable id res no problem, copy your code, an exception will be resolved outside of the file, returns null

simple terms, you're reading via binary file, generate the corresponding Bitmap in Android in the OK

NOT true code returns empty?

The xmlParser type mismatch fact, I told the source code. Eventually returned drawable is empty.

If I write an analytic category, it seems too difficult. But now reduced customer demand, simply set the color of the lines and so on. It is a new problem encountered is
There are two methods GradientDrawable setColors (int [] colors) setOrientation () API Level16 is added, I need to support the 2.3 seems these two methods have to write their own, but this is another issue a new one.
