Auto-complete Text view in android.

In this post we look into the auto complete text view and how it will be used in your app.

Steps 1)Include the Auto-complete Text-view in your XML as following:-

<AutoCompleteTextView
                    android:id="@+id/txt_autoview"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:singleLine="true"
                    android:text=""
                    android:textColor="#000000"
   />

Steps 2)Implements an interface as following:-

public class Depots extends Activity implements TextWatcher {

AutoCompleteTextView  txt_market;
List<String> market;

}

Steps 3)Add the following in your onCreate():-

market = new ArrayList<String>();
txt_market = (AutoCompleteTextView) findViewById(R.id.txt_autoview);

//Before you setting an adapter to the textview you have to add an items to the arraylist.

txt_market.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, market));


Steps 4)Add the Unimplemented methods for your Text Watcher interface.

How To Change Modes Of Phone(Normal,Silent,vibrate) Programmatically.

Today we have seen how to change the modes of phone using audio manager in Android.

1)Declare the Audio manager class.

   AudioManager am;

   am= (AudioManager) getBaseContext().getSystemService(Context.AUDIO_SERVICE);

2)Next, we have to perform an action on particular button to change the mode.

   @Override
   public void onClick(View view) {

        switch (view.getId())
        {

   //For Normal Mode
            case R.id.btn_normal:

                         am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
            break;

   //For Silent Mode
            case R.id.btn_silent:

                        am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
            break;

   //For Vibrate Mode
            case R.id.btn_dnd:
          
                      am.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
          break;
      }
 }
