See more basics on Android along with interview questions The Android Spinner Control is definitely the equivalent of the drop-down selector . By making use of spinner control you basically obtain the capability to choose from a list without taking up all of the display screen space of a ListView. Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one. You can add a spinner to your layout with the Spinner object. You should usually do so in your xml layout with a  <spinner>   element. For example: <Spinner     android:id="@+id/myspinner"     android:layout_width="fill_parent"     android:layout_height="wrap_content" /> Also See....Simple Spinners In Android Here we are going to deal with Customized Spinners.Her...

Falling animation is used to bring transition to a view between two X points or two Y points.

An Alpha Animation is animation that controls the alpha level of an object, i.e. fading it in and out. In Android, you can apply that fading effect to almost anything, from simple text, to images, buttons, check boxes, etc…   This can be done both from xml and from java class. Here I will explain a simple way to give a FadeIn and FadeOut for a textview on button click.. public class Textviewanimation extends Activity { Animation fadeIn,fadeOut; TextView tv; Button startanimation; Boolean fadeflag=true; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_textviewanimation); tv=(TextView) findViewById(R.id.textview); startanimation=(Button) findViewById(R.id.button1); fadeIn = new AlphaAnimation(0.0f , 1.0f ) ; fadeIn.setDuration(1200); fadeIn.setFillAfter(true); fadeOut = new AlphaAnimation(1.0f , 0.0f); fadeO...
