Sending data from one activity to other using bundle

Send data from  Activity

Intent intent =new Intent(this,nextactvitiy.class);
Bundle bundle=new Bundle();
bundle.putString("key",value);
bundle.putString("another key",another value);
intent.putExtras(bundle);
startactivity(intent);


Get data in another Activity

Bundle bundle=getIntent().getExtras();
String s =bundle.getString("key");
String s2=bundle.getString("key2");

Comparing Two dates in Android

 SimpleDateFormat  simpledateformat  = new SimpleDateFormat("yyyy-MM-dd"); 

        Date d1 = simpledateformat  .parse("2018-03-31"); 

        Date d2 = simpledateformat  .parse("2012-03-31"); 

  

        if (d1before  d2) { 

  

            System.out.println("Date1 is before Date2"); 

        } 

  

        else if (d1 after d2) { 

              System.out.println("Date1 is afterrDate2"); 

  

        }



Kindly note:The date formats of both the dates must be same.

CardView in android

Cardview is another material added for designing a layout.It resprents your designin a card manner with the corner radius and  drop elevation (shadow).

Steps to Add CardView in your android studio:

1. Adding Design Dependency

       Build Gradle (Module:App)

dependencies {

implementation 'com.android.support:design:28.0.0'

}

2. Add the <android.support.v7.widget.CardView> widget to your layout and place UI widgets like TextViews, ImageViews inside it.

activity_main.xml

<android.support.constraint.ConstraintLayout
 xmlns:android="http://schemas.android.com/apk/res/android"

    app:layout_constraintTop_toTopOf="parent">


        <LinearLayout          
  android:id="@+id/linear_login"     
  android:layout_width="match_parent"  
  android:layout_height="wrap_content"  
  android:orientation="vertical">


 <android.support.design.widget.TextInputLayout     
           android:id="@+id/text_Username"

      android:layout_height="wrap_content">


                <EditText     
               android:id="@+id/username_l"  
                  android:layout_width="match_parent"    
                android:layout_height="wrap_content"     
               android:hint="Username"

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

            <android.support.design.widget.TextInputLayout

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


                <EditText                  
      android:id="@+id/password_l"              
      android:layout_width="match_parent"             
      android:layout_height="wrap_content"              
      android:hint="Password"

       android:text="Create New User" />

        </LinearLayout>

Multiple File Picker in android

Multiple File Picker Library ,with this a user can pick multiple files for uploading to the server using retrofit or volley..


Dependency used for File Picker

implementation 'com.github.jaiselrahman:FilePicker:1.2.2'



Java File



package com.example.filepicker;

import android.content.Intent;

import android.os.Bundle;
import android.util.Log;
import android.view.View;

import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;

import com.jaiselrahman.filepicker.activity.FilePickerActivity;
import com.jaiselrahman.filepicker.config.Configurations;
import com.jaiselrahman.filepicker.model.MediaFile;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {
    ArrayList<CustomMediaFile> imageArrayList;

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode==123 && resultCode==RESULT_OK){
            ArrayList<MediaFile> files = data.getParcelableArrayListExtra(FilePickerActivity.MEDIA_FILES);
            //Do something with files
            for (int i=0; i<files.size();i++){
                Log.d("MyPaths",files.get(i).getPath());
            }

        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                pickFiles();
            }
        });

    }
    public void pickFiles(){
        imageArrayList = new ArrayList<>();
        Intent filePickerIntent = new Intent(MainActivity.this, FilePickerActivity.class);
        filePickerIntent.putExtra(FilePickerActivity.CONFIGS, new Configurations.Builder()
                .setCheckPermission(true)
                .setMaxSelection(1)
                .setShowImages(false)
                .enableImageCapture(false)
                .setShowVideos(false)
                .setShowAudios(false)
                .setShowFiles(true)
                .setSuffixes(new String[]{"pdf", "doc", "xls"})
                .build());
        startActivityForResult(filePickerIntent, 123);
    }
}

One ProgressBar for whole Project .

ProgressBar can be used in whole Project by creating a single class.THis is demonstrated By the following code...

XML for ProgressBar...

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

<androidx.constraintlayout.widget.ConstraintLayout 

 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"   

 tools:context=".MainActivity">

    <ProgressBar       

 android:layout_width="wrap_content"       

 android:layout_height="wrap_content"      

 android:id="@+id/progressbar"      

 app:layout_constraintBottom_toBottomOf="parent"

 app:layout_constraintLeft_toLeftOf="parent"     

 app:layout_constraintRight_toRightOf="parent"       

 app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

Java File

package com.a.progressbaee;

import android.app.Dialog;
import android.content.Context;

public class ProgressBar extends Dialog {
    public ProgressBar(Context context) {
        super(context);
        setContentView(R.layout.activity_main);

    }

    @Override    public void show() {
        super.show();
    }

    @Override    public void hide() {
        super.hide();
    }

    @Override    public void dismiss() {
        super.dismiss();
    }

    @Override    public void cancel() {
        super.cancel();
    }
}



This can be called in other classes By just 

providing the progressbar class name and creating its object..

ProgressBar progressbar;


TO show progressbar

progressbar.show();


To hide the progressbar

progressbar.hide();

To dismiss the Progrressbar

progressbar.dismiss();

To cancel the progressbar

progressbar.cancel();

Volley for loading data

Volley is a REST  network library which is  used to send and get data from the server we need to do json parsing to fetch data from the server below s the example for the same.

Soap in android #android #soap protocol #xml

Today I will explain to you how to load data using soap. Soap is not much used today but it has its own features like security so it is used even today

Points to Note
SOAP is a communication protocol designed to communicate via Internet.

SOAP can extend HTTP for XML messaging.

SOAP provides data transport for Web services.

SOAP can exchange complete documents or call a remote procedure.

SOAP can be used for broadcasting a message.

SOAP is platform- and language-independent.

SOAP is the XML way of defining what information is sent and how.

SOAP enables client applications to easily connect to remote services and invoke remote methods.
