I'm using Textview with ImageGetter to display html with images. The problem is if there is many images i will face out of memory problems because of the bitmap take too much memory. What should I do to prevent that ?
This is my ImageGetter code :
private class ImageGetter implements Html.ImageGetter {
@Override
public Drawable getDrawable(String source) {
LevelListDrawable d = new LevelListDrawable();
Drawable empty = getResources().getDrawable(R.drawable.indicator_loading);
d.addLevel(0, 0, empty);
d.setBounds((size.x - size.x/5) / 2, 0, size.x/5, size.x/5);
new LoadImage().execute(source, d);
return d;
}
};
class LoadImage extends AsyncTask<Object, Void, Bitmap> {
private LevelListDrawable mDrawable;
@Override
protected Bitmap doInBackground(Object... params) {
String source = (String) params[0];
mDrawable = (LevelListDrawable) params[1];
try {
return picasso.load(Uri.parse(source)).get();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Bitmap bitmap) {
if (bitmap != null) {
if (bitmap.getWidth() < 50) {
return;
}
BitmapDrawable d = new BitmapDrawable(resources, bitmap);
//
mDrawable.addLevel(1, 1, d);
int width = size.x * 90 / 100;
int height = bitmap.getHeight() * width / bitmap.getWidth();
mDrawable.setBounds((size.x - width) / 2, 0, width, height);
mDrawable.setLevel(1);
CharSequence t = textView.getText();
textView.setText(t);
}
}
}
