Swap Tabs / ViewPagers in Android 












" Jai Saraswati Maa" 
Hi ... Dear All ..Today I am uploading a superb example of  Swap Tabs using View Pagers.
This example you can add with your app to give a look like our Phone Dial App.
I am using Android Studio 1.5.1
Minimun SDK API 19
Target SDK API 23
Please Like us & put your valuable suggestions in comment box.

***** Add Dependency in build.gradle file 


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])


    testCompile 'junit:junit:4.12'



    compile 'com.android.support:appcompat-v7:23.3.0'



    compile 'com.android.support:design:23.3.0'



    compile 'com.android.support:support-v4:23.3.0'}






A. ***** Create your own toolbar 


 My toolbar_lay.xml is as and add this with MainActivity Layout file 






<?xml version="1.0" encoding="utf-8"?><android.support.v7.widget.Toolbar



    xmlns:android="http://schemas.android.com/apk/res/android"



    xmlns:app="http://schemas.android.com/apk/res-auto"



    android:layout_width="match_parent" android:layout_height="wrap_content"



    android:background="?attr/colorPrimary"



    android:minHeight="?attr/actionBarSize"



    android:fitsSystemWindows="true"



    android:id="@+id/toolBar"



    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"    >
</android.support.v7.widget.Toolbar>




B. Output screen will be like this


a.     








b.    


    








c.

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;

public class MainActivity extends AppCompatActivity {
    Toolbar toolbar;
    TabLayout tabLayout;
    ViewPager viewPager;
    PagerAdapter pagerAdapter;
    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar = (Toolbar) findViewById(R.id.toolBar);
        setSupportActionBar(toolbar);
        tabLayout = (TabLayout) findViewById(R.id.tabLay);
        viewPager = (ViewPager) findViewById(R.id.viewpager);
        pagerAdapter = new PagerAdapter(getSupportFragmentManager());
        pagerAdapter.addFrag(new Fragment1(), "Ravi");
        pagerAdapter.addFrag(new Fragment2(), "Kumar");

Android Instrumentation Testing  












" Jai Saraswati Maa" 
Hi ... Dear All ..Today I am uploading a superb example of Android Instrumentation Test.
It will l test your code with your emulator or physical device.

In MainActivity i am inserting simple text in edit text and on button click i will display text inserted into TextView.

Its also known as Activity Test. 

I am using Android Studio 1.5.1
Minimun SDK API 19
Target SDK API 23
Please Like us & put your valuable suggestions in comment box.
Just Read Carefully ........ There is some configuration tips required.
**** Nothing added in manifest file or build gradle file so don't worry its very easy.

********* See when you run this test your application runs and disappear.

A.  Layout will be like ....









  

B.    xml code   activity_main.xml




<?xml version="1.0" encoding="utf-8"?>



<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"



    xmlns:tools="http://schemas.android.com/tools"



    android:layout_width="match_parent"



    android:layout_height="match_parent"



    android:paddingBottom="@dimen/activity_vertical_margin"



    android:paddingLeft="@dimen/activity_horizontal_margin"



    android:paddingRight="@dimen/activity_horizontal_margin"



    android:paddingTop="@dimen/activity_vertical_margin"



    tools:context="com.exam.ravi.junittestex1.MainActivity">

    <EditText        android:layout_width="wrap_content"



        android:layout_height="wrap_content"



        android:id="@+id/editText"



        android:layout_alignParentTop="true"



        android:layout_alignParentStart="true"



        android:layout_alignParentEnd="true" />

    <Button        android:layout_width="wrap_content"



        android:layout_height="wrap_content"






        android:text="Click Me"



        android:id="@+id/button"        android:layout_below="@+id/editText"



        android:layout_centerHorizontal="true"



        android:layout_marginTop="42dp"



        android:onClick="clickButton" />

    <TextView        android:layout_width="wrap_content"



        android:layout_height="wrap_content"



        android:textAppearance="?android:attr/textAppearanceLarge"



        android:text="Large Text"



        android:id="@+id/textView"



        android:layout_centerVertical="true"



        android:layout_centerHorizontal="true" />
</RelativeLayout>



C.  Java code  MainActivity.java is as 




package com.exam.ravi.junittestex1;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void clickButton(View view) {
        EditText editText =
                (EditText) findViewById(R.id.editText);

        String name = editText.getText().toString();
        String setData = String.format("Hello, %s!", name);

        TextView textView =
                (TextView) findViewById(R.id.textView);

        textView.setText(setData);
    }
}




*************  Now Test Procedure started .....




1.  Create a Java Class under androidTest Package to test your MainActivity


****** i had created MainActTest which is as 




package com.exam.ravi.junittestex1;

import android.test.ActivityInstrumentationTestCase2;
import android.test.TouchUtils;
import android.widget.Button;
import android.widget.TextView;

public class MainActTest extends ActivityInstrumentationTestCase2<MainActivity> {
    public MainActTest() {
        super(MainActivity.class);
    }

    public void testActivityExists() {
        MainActivity activity = getActivity();
        assertNotNull(activity);
    }
    public void testApply() {
        MainActivity activity = getActivity();
        getInstrumentation().waitForIdleSync();
        getInstrumentation().sendStringSync("Ravi");
        Button button =
                (Button) activity.findViewById(R.id.button);

        TouchUtils.clickView(this, button);
        TextView message = (TextView) activity.findViewById(R.id.textView);
        String actualText = message.getText().toString();
        assertEquals("Hello, Ravi!", actualText);

    }


} 


2.  How configure ......


step 1. Select Android Instrumentation Tests in Build Variant  as  








step 2. configure your AndroidTest Package using Edit Configuration with Run 










step 3 Run your Test 


3.1   Successful ..... when inserted and expected are same Text .... 










3.2   Failed ....  when inserted and expected are not same  Text ....

Android Testing - JUnit Test












" Jai Saraswati Maa" 
Hi ... Dear All ..Today I am uploading a superb example of JUnit test.

JUnit test will test your code on JVM basis.

I had created one simple class NumAdder with a method addNumber which returns only addition of two numbers..



I am using Android Studio 1.5.1

Minimun SDK API 19
Target SDK API 23
Please Like us & put your valuable suggestions in comment box.

Just Read Carefully ........ There is some configuration tips required.

**** No layout file required for this example.

**** Nothing added in manifest file or build gradle file so don't worry its very easy.



A. My Java class look like this -  in my package




package com.exam.ravi.junittestex1;

public class NumAdder
{
 public static  int addNumber(int first,int second)
 {
     return first+second;
 }
}




B. My Test class .... i am using default created class by AndroidStudio


which is ExampleUnitTest.java  in test folder(with same package name).




package com.exam.ravi.junittestex1;

import org.junit.Test;
import static org.junit.Assert.*;
public class ExampleUnitTest {
    @Test    public void addition_isCorrect() throws Exception
    {
        int result = NumAdder.addNumber(2,3);
        assertEquals(5, result);
    }
}




C. How configure ..... 






step 1. please select option Unit Tests in build variant see below 


        













step 2. Edit Run configuration  like 










step 3. Run ExampleUnitTest and see the result 






1. successful ------ see It's Green  






 










2. Fail ---- Please change expected result and actual result in ExampleUnitTest
