In this tutorial implement the circle ImageView in Android.we will drow the design in xml using eclipse.
first, we will create a gradient class in Drawable folder my class is cercle_image.xml.



...................................................................................................................................................................
<?xml version="1.0" encoding="UTF-8" ?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android">
  <solid android:color="#000000" />
  <stroke android:width="3dp" android:color="#776da8" />
  <corners android:bottomRightRadius="100dp" android:bottomLeftRadius="100dp" android:topLeftRadius="100dp" android:topRightRadius="100dp" />
  <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
  </shape>





then you have set the class in ImageView in main class
..............................................................................................................................................................
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
     android:background="#000000">

    <ImageView
        android:id="@+id/image"
        android:layout_width="200dip"
        android:layout_height="200dip"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:scaleType="centerCrop"
        android:background="@drawable/cercle_image"
        android:src="@drawable/iconprofile" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

In this Tutorial we will explain how to implement animated Numberpicker dialog with bounce.

first we will create animated xml class ,

res/anim/bounce.xml
..............................................................................................................................................................
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/bounce_interpolator">
    <translate
        android:fromYDelta="-100%p"
        android:toYDelta="0"
        android:duration="2000"/>

           android:duration="@android:integer/config_mediumAnimTime"/> 

................................................................................................................................................................
res/value/styles
Then both anim class add in style theam,  how explain below
...................................................................................................................................................................

In this tutorial we will explain how to create TabLayout in android.explain below.Tabhost show as multiple options menu .Now we created 3 Activity and 3 xml class.

 main.xml

In this class create Tablayout android wigdets.
........................................................................................................................................................
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"

In this tutorial we will explain how to detect Internet connection. the internet connection we will find before  call http request and json etc , in our android application.

first you have declare internet accuses permission in Manifest.xml.



 <uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Internet_Status.java
..........................................................................................................................................................

package com.androidbeginnerpoint.testapplication;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;

public class Internet_Status {
   
    private Context _context;
   
    public Internet_Status(Context context){
        this._context = context;
    }

    public boolean isConnectingToInternet(){
        ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService(Context.CONNECTIVITY_SERVICE);
          if (connectivity != null)
          {
              NetworkInfo[] info = connectivity.getAllNetworkInfo();
              if (info != null)
                  for (int i = 0; i < info.length; i++)
                      if (info[i].getState() == NetworkInfo.State.CONNECTED)
                      {
                          return true;
                      }

          }
          return false;
