Different types of SnackBar in Android Studio

About Example:- Here is the basic example that "How to Show different Types of Snackbar  in Android Application By Coding"

Basic Requirement:-
1. MainActivity.java  | activity_main.xml
Steps are:-

Step 1:Add a new project and open build.gradle and add one line inside dependencies:-

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

   // CardView       compile 'com.android.support:cardview-v7:26+'

        compile 'com.android.support:design:26.+'    }) 
}

Step 2:  Open activity_main.xml and write following code:-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center"
    tools:context="com.example.supriyabharti.snackbarexample.MainActivity">
<android.support.v7.widget.CardView
    android:layout_width="match_parent"
    android:layout_height="240dp"
    android:layout_margin="40dp"
    android:elevation="3dp"
    app:cardCornerRadius="4dp"
    android:layout_gravity="center">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:gravity="center">
        <Button
            android:id="@+id/simpleSank"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:text="Simple Snackbar View"/>
        <Button
            android:id="@+id/actionSank"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:text="Action Callback Snackbar"/>
        <Button
            android:id="@+id/customSank"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:text="Simple Snackbar View"/>
    </LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>

Step 3:Open MainActivity.java and do the following coding:-

package com.example.supriyabharti.snackbarexample;

import android.graphics.Color;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {
    Button btnSimple,actionSnackar,customSnackbar;

    @Override   

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btnSimple=(Button)findViewById(R.id.simpleSank);
        actionSnackar=(Button)findViewById(R.id.actionSank);
        customSnackbar=(Button)findViewById(R.id.customSank);

        //listner on button...     

   btnSimple.setOnClickListener(new View.OnClickListener() {
            @Override        

    public void onClick(View view) {
                Snackbar simpleSnackbar=Snackbar.make(view,"Please check your Internet connection!!",Snackbar.LENGTH_SHORT);
                simpleSnackbar.show();
            }
        });

        //action callback....     

   actionSnackar.setOnClickListener(new View.OnClickListener() {
            @Override           

 public void onClick(View view) {
                Snackbar actionSnack=Snackbar.make(view,"Service Unavailable",Snackbar.LENGTH_LONG)
                        .setAction("Retry", new View.OnClickListener() {
                            @Override  

                          public void onClick(View view) {
                            Snackbar snackbar1=Snackbar.make(view,"Connected Successfully",Snackbar.LENGTH_LONG);
                                snackbar1.show();
                            }
                        });
                actionSnack.show();
            }
        });

        //custom snackbar....       

        customSnackbar.setOnClickListener(new View.OnClickListener() {
        @Override        

        public void onClick(View view) {
        Snackbar customSnackbar=Snackbar.make(view,"Message Deleated",Snackbar.LENGTH_LONG).setAction("UNDO", new View.OnClickListener() {
        @Override            

        public void onClick(View view) {
                        Snackbar snackbar2=Snackbar.make(view,"Message Stored",Snackbar.LENGTH_LONG);
                        snackbar2.show();
                    }
                });
                customSnackbar.setActionTextColor(Color.RED);
                //change snackbar message color.....      

          View sView=customSnackbar.getView();
                TextView tv=(TextView)sView.findViewById(android.support.design.R.id.snackbar_text);
                tv.setTextColor(Color.YELLOW);
                customSnackbar.show();

            }
        });

    }
}

Step 3:- Output will be like:-

Simple Snackbar View

Action callback Sbackbar

Custom design of Snackbar

Step 4:Output are:-

Adding TabsLayout (Tabs) | With Text and Icon in Android Studio

About Example:- Here is the basic example that "How to Add TabsLayout   in Android Application By Coding"

Basic Requirement:-
1. MainActivity.java  | activity_main.xml
Steps are:-

Step 1: Add a new project and open activity_main.xml and write following code:-<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" 

android:orientation="vertical"

android:layout_width="match_parent" 

android:layout_height="match_parent">

    <android.support.design.widget.TabLayout 

    android:id="@+id/tabsLayout1"    

    android:layout_width="match_parent"

    android:layout_height="wrap_content" 

    app:tabMode="fixed"       

    app:tabGravity="fill">

</android.support.design.widget.TabLayout>

<android.support.v4.view.ViewPager   

 android:id="@+id/viewPager1"   

 android:layout_width="match_parent"  

 android:layout_height="match_parent">

</android.support.v4.view.ViewPager>
</LinearLayout>

Step 2: Add some Fragment classes as much as u needs to show in tabs, here i am adding 3 classe:- Right click on your package and add new java class:-

 A). GameFragment.java | SongFragment.java | MovieFragment.java

B) In every class code will be like following:-

public class GameFragment extends android.support.v4.app.Fragment {
    public static final String ARG_OBJECT = "object";
    @Nullable    

@Override    

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
        View v=inflater.inflate(R.layout.gamefargment,container,false);
        Bundle args=getArguments();
        TextView tv=(TextView)v.findViewById(R.id.tvgame);
        tv.setOnClickListener(new View.OnClickListener() {
            @Override            public void onClick(View view) {
                Toast.makeText(getActivity(),"Click 1",Toast.LENGTH_LONG).show();
            }
        });
        
        return v;
    }
}

C) gamefragment.xml will be like following:-

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

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

 android:orientation="vertical" 

android:layout_width="match_parent"    

android:layout_height="match_parent"  

  android:background="#DAF7A6"   

 android:gravity="center">
    <TextView        

android:id="@+id/tvgame"  

      android:layout_width="match_parent"       

 android:layout_height="wrap_content"      

  android:text="Game"      

  android:textSize="30sp"      

  android:gravity="center"/>


</LinearLayout>

Step 3:  Open MainActivity  and write following code:-

public class MainActivity extends AppCompatActivity{


    ViewPager viewPager;
    TabLayout tabLayout;
    int[] iconList={R.drawable.game,R.drawable.song,R.drawable.mov};
    @Override    

protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tabLayout=(TabLayout)findViewById(R.id.tablaout3);
        viewPager=(ViewPager)findViewById(R.id.viewPager3);
        tabLayout.setupWithViewPager(viewPager);
        setViewAdapter4(viewPager);
        setIcon();

    }

    //set class to releted tabs....    public void setViewAdapter4(ViewPager vp){
        ViewPagerAdapterClasss3 adapter=new ViewPagerAdapterClasss3(getSupportFragmentManager());
        adapter.addFragment(new GameFragment(),"Game");
        adapter.addFragment(new SongFragment(),"Song");
        adapter.addFragment(new MovieFragment(),"Movie");
        vp.setAdapter(adapter);

    }
    //set icon method start..    public void setIcon(){
        tabLayout.getTabAt(0).setIcon(iconList[0]);
        tabLayout.getTabAt(1).setIcon(iconList[1]);
        tabLayout.getTabAt(2).setIcon(iconList[2]);
    }
}
class ViewPagerAdapterClasss3 extends FragmentPagerAdapter {
    final List<Fragment> mFragmentAdd4=new ArrayList<>();
    final List<String> mTitel4=new ArrayList<>();
    @Override   

 public Fragment getItem(int position) {
        return mFragmentAdd4.get(position);
    }

    @Override   

 public int getCount() {
        return mFragmentAdd4.size();
    }

    @Override    

public CharSequence getPageTitle(int position) {
        return mTitel4.get(position);
    }
    public void addFragment(Fragment fragment,String titel){
        mFragmentAdd4.add(fragment);
        mTitel4.add(titel);

    }

    public ViewPagerAdapterClasss3(FragmentManager fm) {
        super(fm);
    }
}

Step 4: Open build.gradle and add following:-

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'    })
    compile 'com.android.support:appcompat-v7:26.+'    compile 'com.android.support:design:26.+'
    
}

Step 1: Output will be like:-

     android:layout_height="wrap_content"       

     android:text="Hello World!"     

     app:layout_constraintBottom_toBottomOf="parent"       

     app:layout_constraintLeft_toLeftOf="parent"       

     app:layout_constraintRight_toRightOf="parent"    

     app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

Step 2:- MainActivity.java

import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;

public class MainActivity extends AppCompatActivity {

    @Override    
        protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //code for changing ActionBar color of an activity       
       getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.colorAccent)));

        //code for to change statusbar color of an activity.....        
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Window window = getWindow();
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.setStatusBarColor(Color.RED);
        }
    }
}

SignUp | Login | User's Setting by using SharedPreferences in Android

About Example:- Here is the example that "How to do SignUp | Login and Update user's Profile  in Android Application By using Coding"

Basic Requirement:-
1. MainActivity.java  | activity_main.xml
2.Login |   login.xml
3.Signup | signup.xml
4.UserProfile   |   user_profile.xml
5.UserProfileUpdate   | user_profile_update.xml
6.SharedConstant

Steps are:-
Step 1: Add a new project and open activity_main.xml and write following code:-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
    android:orientation="vertical"
    android:gravity="center"
    android:layout_height="match_parent">

    <TextView
        android:textSize="20sp"
        android:id="@+id/uerName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="30dp"
        android:text="Welcome"/>

</LinearLayout>

Steps 2: MainActivity.java

package com.example.supriyabharti.profilesettingexmp;


import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.os.Handler;
import android.preference.PreferenceManager;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    SharedConstant sharedConstant;
    @Override   

       protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        sharedConstant=new SharedConstant(MainActivity.this);

        new Handler().postDelayed(new Runnable(){
            public void run(){
                String strUserPhone=sharedConstant.getStringPref("userPhone");
                if(strUserPhone.matches("")){
                    startActivity(new Intent(MainActivity.this,SignUp.class));
                    finish();
                }else {
                    startActivity(new Intent(MainActivity.this, UserProfile.class));
                    finish();
                }
            }

        },3000 );

    }
}

Steps 3: SharedConstant.java

package com.example.supriyabharti.profilesettingexmp;

import android.content.Context;
import android.content.SharedPreferences;
public class SharedConstant  {

    SharedPreferences preferences;
    SharedPreferences.Editor editor;
    public SharedConstant(Context context) {
        preferences=context.getSharedPreferences("MyData", Context.MODE_PRIVATE);
    }

    public  void setPrefString(String key,String value){
        editor=preferences.edit();
        editor.putString(key,value);
        editor.commit();
    }
    public  String getStringPref(String key){
        return preferences.getString(key,"");
    }
}
