Dynamic List-View Demo in Android | Dynamically Increase row of list-view in Android | Custom Dynamic list-view in Android

Hello Friends!

Today I am going to post a logical code for add item in list-view dynamically. And increase size of row dynamically.

1)CustomListView.java
package com.manish.customlistview;

import java.util.ArrayList;

import android.os.Bundle;

import android.widget.ListView;

import android.app.Activity;

/**

public class CustomListView extends Activity {

       ArrayList<Item> imageArry = new ArrayList<Item>();

       CustomImageAdapter adapter;

       @Override

       public void onCreate(Bundle savedInstanceState) {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.main);

              // add image and text in arraylist

              String Video[]={"xyz","abcd"};

              String Song[]={"xyz","abcd","pqerttt","yuioo"};

              String Movi[]={"xyz","abcd","qwer","yuioo","tyyuu","ggggggg","yuioo","tyyuu","ggggggg"};

             

              imageArry.add(new Item(R.drawable.facebook, Song));

              imageArry.add(new Item(R.drawable.outlook, Video));

              imageArry.add(new Item(R.drawable.google, Movi));

             

              // add data in contact image adapter

              adapter = new CustomImageAdapter(this, R.layout.list, imageArry);

              ListView dataList = (ListView) findViewById(R.id.list);

              dataList.setAdapter(adapter);

       }

}

2)CustomImageAdapter.java

                     Item myImage = data.get(position);

                     for (int j = 0; j < myImage.getName().length; j++) {

                           TextView label = new TextView(context);

                           label.setText(myImage.name[j]);

                           linearMain.addView(label);

                     image.setImageResource(outImage);

                     linearMain.addView(image);

              }

              return row;

       }

}

Google account Integration in Android | Login with Gmail | Signup with Google in Android | Get Google Profile photo in Android

Hello Friends,
This is my post for Google account integration with your application,  login with gmail, signup with Google account. Some important step is given below-

Step 1- Create new project say GoogleProfileDemo.
Step 2- Add "Google play service" libray project.
Step 3 - Add needed permission in manifest.xml-

 <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.NETWORK" />
    <uses-permission android:name="android.permission.USE_CREDENTIALS" />
