Issue
I'm trying to make a button with StateListDrawable but with 2 remote images.
I'm trying like this :
package com.mylisabox.common.helpers;
import android.graphics.drawable.Drawable;
import android.graphics.drawable.StateListDrawable;
import android.os.AsyncTask;
import java.io.InputStream;
import java.net.URL;
/**

public class RemoteStateListDrawable extends StateListDrawable
{
Drawable drawableOn;
Drawable drawableOff;
public RemoteStateListDrawable(String urlOn, String urlOff)
{
loadImageAsDrawable(urlOff, false);
loadImageAsDrawable(urlOn, true);
}
@Override
protected boolean onStateChange(int[] stateSet)
{
return super.onStateChange(stateSet);
}
@Override
public boolean isStateful()
{
return true;
}
public void loadImageAsDrawable(final String url, final boolean isOnState)
{
new AsyncTask<Void, Void, Drawable>()
{
@Override
protected Drawable doInBackground(Void... params)
{
try
{
// open the stream
InputStream is = new URL(url).openStream();
String imageName = "src";
Drawable draw = Drawable.createFromStream(is, imageName);
return draw;
}
catch (Exception e)
{
// something went wrong
return null;
}
}
@Override
protected void onPostExecute(Drawable drawable)
{
super.onPostExecute(drawable);
if (isOnState)
{
drawableOn = drawable;
addState(new int[]{android.R.attr.state_pressed, android.R.attr.state_selected}, drawableOn);
}
else
{
drawableOff = drawable;
addState(new int[]{}, drawableOff);
}
}
}.execute();
}
}
But it's not working... The off image was show but never the on image if I click on the button.
Solution
android.R.attr.state_pressed, android.R.attr.state_selected is mean pressed and selected , remove selected and try again 2.try to exchange the off and on drawable 3.try to use diffenent imageName
String imageName = "src";
