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

package com.manish.customlistview;

import java.util.ArrayList;

import android.app.Activity;

import android.content.Context;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ArrayAdapter;

import android.widget.ImageView;

import android.widget.LinearLayout;

import android.widget.TextView;

/**

 *

 * @author manish

 *

 */

public class CustomImageAdapter extends ArrayAdapter<Item> {

       Context context;

       int layoutResourceId;

       LinearLayout linearMain;

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

       public CustomImageAdapter(Context context, int layoutResourceId,

                     ArrayList<Item> data) {

              super(context, layoutResourceId, data);

              this.layoutResourceId = layoutResourceId;

              this.context = context;

              this.data = data;

       }

       @Override

       public View getView(int position, View convertView, ViewGroup parent) {

              View row = convertView;

              if (row == null) {

                     LayoutInflater inflater = ((Activity) context).getLayoutInflater();

                     row = inflater.inflate(layoutResourceId, parent, false);

                     linearMain = (LinearLayout) row.findViewById(R.id.lineraMain);

                     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);

                     }

                     ImageView image = new ImageView(context);

                     int outImage = myImage.image;

                     image.setImageResource(outImage);

                     linearMain.addView(image);

              }

              return row;

       }

}

3)Item.java

package com.manish.customlistview;

/**

 *

 * @author manish

 *

 */

public class Item {

       int image;

       String name[];

      

       public Item(int image, String[] name) {

              super();

              this.image = image;

              this.name = name;

       }

       public int getImage() {

              return image;

       }

       public void setImage(int image) {

              this.image = image;

       }

       public String[] getName() {

              return name;

       }

       public void setName(String[] name) {

              this.name = name;

       }

}
