Send object one activity to another activity (Using intent)

First of all create Serializable interface

like :-

          public class Model implements Serializable {

Create model Class implement Serializable 

import java.io.Serializable;

public class Model implements Serializable{




public String Userid, Type;


public String getUserid() {
return Userid;
}

public String setUserid(String Userid) {
this.Userid = Userid;
return Userid;
}

public String getType() {
return Type;
}

public String setType(String Type) {
this.Type = Type;
return Type;
}

and then pass object Model class

Model mod = new Model();

Intent intent = new Intent(firstactivity.this, Secondactivity.class);
intent.putExtra('Name',mod);

Retrive value from one activity to another activity 

Model object  = getIntent().getSerializableExtra("name");

Reference:-

Android intent

how to store web service result in array list in android

Final Result of Webservice 

[{

 "Type": "Data",
 "d": {
  "UserID": "30Bq33f685k=",
  "Name": "testing13",
  "TuitionID": "30Bq33f685k=",
  "ContactNo": "",
  "UserType": "UserAdmin"
 }
}, {
 "Type": "Message",
 "d": ""
}]

In my case one json array and two object

Step-1

Store result to resultstring

resultString = (SoapPrimitive) envelope.getResponse();

Step-2

 Store result in jsonstring for create json array               

                String jsonStr = String.valueOf(resultString);
                Log.e(TAG, "Response from result" + resultString);


                if (jsonStr != null) {

Step-3

Create json array and parameter

                    JSONArray jsonArray = new JSONArray(jsonStr);
                    Log.e(TAG, resultString.toString());

                    for (int i = 0; i < jsonArray.length(); i++) {
//                        Toast.makeText(Loginscreen_activity.this, "demo.....", Toast.LENGTH_SHORT).show();
                        JSONObject c = jsonArray.optJSONObject(0);

                        if (i == 0 && c.optString("d").equalsIgnoreCase("Invalid login")) {

                            runOnUiThread(new Runnable() {
                                @Override                                public void run() {
                                    Toast.makeText(Loginscreen_activity.this, "Error", Toast.LENGTH_SHORT).show();
                                }
                            });

                        } else {

                            final JSONObject data = c.optJSONObject("d");

                            model model = new model();
                            model.setUserid(data.optString("UserID"));
                            model.setName(data.optString("Name"));
                            model.setTuitionid(data.optString("TuitionID"));
                            model.setContactno(data.optString("ContactNo"));
                            model.setUsertype(data.optString("UserType"));

                            list.add(model);
                            Log.d("ARRAY>> ", "" + list.size());
                        }
                    }

                    Log.d("ArraySize", String.valueOf(jsonArray));
                }

Simple music player in android

Step1:  create xml file and add three button 
              Name is start stop and pause 
Step2: add music in res->raw folder
Step3: create java file and add this code




MainActivity.java


package com.example.anshu.music;

import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    MediaPlayer Song;
    int pause;
    int stop;

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

    public void play(View view){
        if(Song == null){
            Song = MediaPlayer.create(this , R.raw.song);
            Song.start();
            Toast.makeText(MainActivity.this, "Song Play", Toast.LENGTH_SHORT).show();    }

        else if(!Song.isPlaying()){
            Song.seekTo(pause);
            Song.start();
            Toast.makeText(MainActivity.this, "Song Play", Toast.LENGTH_SHORT).show();
    }
    }
    public void pause(View view){
        if(Song!= null){
            Song.pause();
            pause = Song.getCurrentPosition();
            Toast.makeText(MainActivity.this, "Song Pause", Toast.LENGTH_SHORT).show();
        }
    }
    public void stop(View view){

        if (Song!=null)
        {
            Song.stop();
            Song.release();
            Song.reset();

            Song = null;
        }

        /*Song.stop();
       Song = null;
        Toast.makeText(MainActivity.this, "Song Stop", Toast.LENGTH_SHORT).show();*/

expand and collapse example with animation in android

smooth expand/collapse animation in android 

Screenshot

When you click on plus(+) button it will Expand and Collapse Layout

Step1: Create animation folder under res folder 

              then Create Expand.xml and Collapse.xml file in animation folder

Expand.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:fillAfter="true">

    <scale        android:duration="500"        android:fromXScale="1.0"        android:fromYScale="0.0"        android:interpolator="@android:anim/linear_interpolator"        android:toXScale="1.0"        android:toYScale="1.0" />

</set>

Collapse.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:fillAfter="true" >

    <scale        android:duration="500"        android:fromXScale="1.0"        android:fromYScale="1.0"        android:interpolator="@android:anim/linear_interpolator"        android:toXScale="1.0"        android:toYScale="0.0" />
