Android ViewFlipper

Android ViewFlipper

-->

Simple ViewAnimator that will animate between two or more views that have been added to it. Only one child is shown at a time. If requested, can automatically flip between each child at a regular interval.

Below i wrote the code for through flipping you can see the next ITEM or Previous Item with Animation.

Android Adapterview

Android Adapterview

An AdapterView is a view whose children are determined by an Adapter.

See Listview, Gridview, Spinner and Gallery for commonly used subclasses of AdapterView.
Below the example just i create array of values and set that values into ArrayAdapter.
Array of string  values 
Step 1

private static final String[] AndroidVersion = {

"Android2.1", "Android2.2", "Android2.3",

"Android3.0", "Android3.2", "Android4.0",

"Android4.1"

};

Step 2. i created one XML in that having Spinner lauout.
Spinner s = (Spinner) findViewById(R.id.spinner);

Step 3

then i added the array of values to ArrayAdapter

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,

android.R.layout.simple_spinner_item, AndroidVersion);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

Step 4.

Then Set the adapter to spinner 

s.setAdapter(adapter);

*Same like listview and Galleryview and Gridview

Step 5. Output -run the application

Android AnalogClock

Android AnalogClock

This widget display an analogic clock with two hands for hours and minutes.  

 a) Anlogclock

Like AnalogClock, but digital. Shows seconds. FIXME: implement separate views for hours/minutes/seconds, so proportional fonts don't shake rendering 

 b) Digitalclock

Android Action Bar

Android ActionBar 

The action bar is a window feature that identifies the application and user location, and provides user actions and navigation modes. You should use the action bar in most activities that need to prominently present user actions or global navigation, because the action bar offers users a consistent interface across applications and the system gracefully adapts the action bar's appearance for different screen configurations. You can control the behaviors and visibility of the action bar with the ActionBar APIs, which were added in Android 3.0 (API level 11).

i) Using Tabs ActionBar
ii)Demonstrates idiomatic usage of the Action Bar.

i) Using Tabs ActionBar

A tab in the action bar.

Tabs manage the hiding and showing of Fragments.

 ii)Demonstrates idiomatic usage of the Action Bar.

This demonstrates idiomatic usage of the Action Bar. The default Honeycomb theme includes the action bar by default and a menu resource is used to populate the menu data itself. If you'd like to see how these things work under the hood, see ActionBarMechanics.
Android  Quick Action Bar.
Quick Actions are basically actions/functions in a popup bar that are triggered by specific visual elements/buttons/items on the screen. Quick Actions are used to display contextual actions typically used in list views but not limited to it. You can imagine a phone-book or contact list on the phone. Now, there are certain set of actions that will be common to all contacts in the views like; make a call, send message, edit contact or may be even transfer files by  Email, Bluetooth etc. Basically these functions that are common to items in a context can be put in the Quick Action bar. This way the screen is uncluttered and simple and more importantly we needn’t sacrifice on the actions needed.

Create Actionable Items:
The below code snippet is used to create an actionable item i.e. the actions you would want to place in the quick action bar. Creating an actionable item involves specifying the title, setting an icon that represents the item which will help you relate to the action, and finally set a Listener for the action. The term itself is self-explanatory. Yes, it is used to determine the action to be performed when clicked or pressed. As far as the icon /image goes, it can be easily set by referring to it from the resources as is the case with any external resource set in android which you would aware of, I am most certain.

final QuickActionIcons edit = new QuickActionIcons();;
 edit.setTitle("Edit");
 edit.setIcon(getResources().getDrawable(R.drawable.edit));
 edit.setOnClickListener(new OnClickListener()
 {
 public void onClick(View v)
 {
// add u r action
 }

 });]


Create Quick Action Dialog:

This part is even simpler. Like in this example, when an item in the list view is clicked / pressed, a new quick action bar/dialog is created. Then all the actionable items that you have created in the previous step are appended one by one to the quick action bar. After this you simply have to specify the animation style i.e. how do you want the dialog to be displayed on screen.

resultPane.setOnItemClickListener(new OnItemClickListener()
    {
    public void onItemClick(AdapterView<?> parent, View view, int position, long id)
    {
      QuickActionBar qab = new QuickActionBar(view);

      qab.addItem(edit);
      qab.addItem(call);
      qab.addItem(send_data);
      qab.setAnimationStyle(QuickActionBar.GROW_FROM_LEFT);

      qab.show();
    }
    });
