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.
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:
- Using BlurListFragment.
- 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("https://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);
}
}
- In order for this library to work, you need to set your
ActionBar
to overlay mode. Go here for steps on how to set yourActionBar
to overlay mode.
