I wanted to set Linear Layout background dynamically in the following way:
Fetch image from web url through XML parsing and then store that image into sd card.
Now the image saved into sd card.
Set that image as a linear layout background in the app.
Now I am stuck in the third step. Can anyone help?
Use this:
Bitmap bmImg = BitmapFactory.decodeStream(is);
BitmapDrawable background = new BitmapDrawable(bmImg);
linearLayout.setBackgroundDrawable(background);
Also check this: How to convert a Bitmap to Drawable in android?
bmImg = BitmapFactory.decodeStream(is); BitmaBitmapDrawable background = new BitmapDrawable(bmImg); linearLayout.setBackgroundDrawable(background);
new BitmapDrawable(bmImg) is deprecated. Use new BitmapDrawable(getContext().getResources(), bmImg) instead.I have done this way:
private RelativeLayout relativeLayout;
onCreate:
relativeLayout= (RelativeLayout)findViewById(R.id.relativeLayout);
new LoadBackground("http://www.tmonews.com/wp-content/uploads/2012/10/androidfigure.jpg",
"androidfigure").execute();
AsyncTask to load image in background:
private class LoadBackground extends AsyncTask<String, Void, Drawable> {
private String imageUrl , imageName;
public LoadBackground(String url, String file_name) {
this.imageUrl = url;
this.imageName = file_name;
}
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected Drawable doInBackground(String... urls) {
try {
InputStream is = (InputStream) this.fetch(this.imageUrl);
Drawable d = Drawable.createFromStream(is, this.imageName);
return d;
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
private Object fetch(String address) throws MalformedURLException,IOException {
URL url = new URL(address);
Object content = url.getContent();
return content;
}
@Override
protected void onPostExecute(Drawable result) {
super.onPostExecute(result);
relativeLayout.setBackgroundDrawable(result);
}
}
Hope this will help you.
An easier way:
BitmapDrawable d = new BitmapDrawable("/sdcard/data/image.jpg");
linearLayout.setBackgroundDrawable(d);
API are deprecated you can use the below code
BitmapDrawable background = new BitmapDrawable(getResources(), bitmapImage);
linearLayout.setBackground(background);
Try to use this:
Bitmap bmpOriginal = BitmapFactory.decodeResource(getResources(), R.drawable.img);
BitmapDrawable bmpBackground = new BitmapDrawable(getResources(), bmpOriginal)
Use @Deimos's answer, but like this since some methods are deprecated now
Bitmap bmImg = BitmapFactory.decodeStream(is);
BitmapDrawable background = new BitmapDrawable(context.getResources(), bmImg);
linearLayout.setBackground(background);
You can also set image from drawable folder.
yourView.setBackgroundResource(R.drawable.FILENAME);
That set FILENAME as background image.
