Handling Views

 

 

Handling different Views in Android: There are different types of Views in Android.

They are 1) TextView

2) EditText
3) Button

4) RadioButton

5) CheckBox

6) Switch

7) ToggleButton | | | |

To work with all the above views, there are some common steps. They are
1) Create View in XML

2) Set id for the View

3) Identify the same View in Activity

4) Set appropriate listeners for each View.

The purpose of the listener is to identify the behavioral change in Views and events. So, whenever there is any change happened in View runtime, this listener tracks that and appropriate overridden method called.
The listeners for different views are as follows
-> For all the Views. Mainly for Buttons – OnClickListener -> RadioButton, RadioGroup, CheckBox, Switch, ToggleButton – OnCheckedChangedListener -> RatingBar – OnRatingBarChangeListener -> SeekBar – OnSeekBarChangeListener
