BlurStickyHeaderListView

What is BlurStickyHeaderListView?

It is a custom ListView with a header that displays pictures from an URL. It then adds a nice blur/parallax effect to the downloaded picture. It also provides the option of a sticky title. Here is a video of it in action.

How do I use the thing?

Add compile 'me.emmano:blurstickyheaderlistview:0.1.+' to the dependencies{} in your build.gradle. If you do not aleady have jcenter() added to your project, do so by adding the following to build.gradle:

repositories {
    jcenter()
}

You also need to add renderscript to your project. If using android studio add the following to defaultConfig{} inside build.gradle:

defaultConfig {
    //Other config...
    renderscriptTargetApi 19
    renderscriptSupportMode true
}

BlurStickyHeaderListView is pretty straight forward to use. You have two alternatives:

1. Using BlurListFragment.
2. Using BlurListView.

Regardless of which option you use the API is the same. Here is a snippet for your reference.

import com.emmano.blurstickyheaderlistviewlib.fragment.BlurListFragment;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;

import java.util.Arrays;


public class MyActivity extends FragmentActivity {

    public static final String DUMMY_TEXT =
            "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore "
                    + "magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
                    + " Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur."
                    + " Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
        if (savedInstanceState == null) {
            final ArrayAdapter<String> listAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, Arrays.asList(DUMMY_TEXT, DUMMY_TEXT));
            
          final BlurListFragment blurListFragment = new BlurListFragment();
            //Set up the BlurListFragment before you call FragmentTransaction.commit() methods called after commit() will do nothing.
            blurListFragment.setRetainInstance(true); // for configuration changes.
            blurListFragment.controlActionBar(true);
            blurListFragment.setActionBarColor("#RRGGBB") //adds Google+ effect to ActionBar.
            blurListFragment.setEnableLogging(true);
            
            // For more image configuration stuff BlurListFragment.loadHeaderImage(RequestCreator picassoCreator) could be used

            blurListFragment.loadHeaderImage("http://someimage",R.drawable.ic_launcher);
            blurListFragment.setBlurHeaderListAdapter(listAdapter);
            blurListFragment.shouldTitleStick(true);
            getSupportFragmentManager().beginTransaction().add(R.id.container, blurListFragment,BlurListFragment.class.getSimpleName()).commit();

        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.my, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

Limitations

1. In order for this library to work, you need to set your ActionBar to overlay mode. Go here for steps on how to set your ActionBar to overlay mode.
