private ReadNameAndNum rnan;
private Thread t1 ;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    callView=View.inflate(this, R.layout.call, null);
    callViewLayer=new LockUtil(this);
    callViewLayer.setLockView(callView);
    callViewLayer.lock();
    callView.findViewById(R.id.callBack).setOnClickListener(this);

    rnan=new ReadNameAndNum();
    t1=new Thread(rnan);
    t1.start();


}
class ReadNameAndNum implements Runnable{
    ContentResolver cr= getContentResolver();
    Cursor c=cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
    @Override
    public void run() {
        System.out.println(">>>>>RUN");
        while (c.moveToNext()) {
            int nameFieldColumnIndex= c.getColumnIndex(PhoneLookup.DISPLAY_NAME);
            String contact=c.getString(nameFieldColumnIndex);

            int numberFieldColumnIndex=c.getColumnIndex(PhoneLookup.NUMBER);
            String number=c.getString(numberFieldColumnIndex);

            System.out.println(">>>>>"+contact+">>>>"+number);
        }
        c.close();
    }}
