List Background not Transparent when Scrolling

 If you want a ListView with a transparent background you need to add either:

In the xml-declaration of it, or something like:

ListView v = getListView();

v.setCacheColorHint(0);

How to get Phone Number in Android application..???

import android.app.Dialog;
import android.content.Context;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;

public class ClsGetPhoneNumber_UI {
 Dialog dialog;
 String strPHNo;
 StringBuffer sb;

 public String getMyPhoneNumber(Context context){
   
    TelephonyManager mTelephonyMgr;
       mTelephonyMgr = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
       try
       {
        sb=new StringBuffer(mTelephonyMgr.getLine1Number());
        System.out.println("Sb"+sb.toString());
      
        if(sb==null)
        {
         strPHNo= "NOPHONE";
         System.out.println("strPHNo1"+strPHNo);
        }
        else if(sb.toString().equals(""))
        {
         return "NOPHONE";
        }
        else
        {
         sb.reverse().setLength(10);
         String ReverseNumber=sb.toString().trim();
         strPHNo= ReverseNumber;
         System.out.println("strPHNo2"+strPHNo);
        }
       }
       catch(Exception e)
       {
        System.out.println("strPHNo3"+strPHNo);
        return "NOPHONE";
       }
    return strPHNo;
 }
}
It will return Phone Number. If it will not able to get phone number then it will return NOPHONE.

Add Email Address from Contact Picker

1). Add permission in to the Menifest.xml
