Simple Listview

STYLES FOR LIST VIEW IN ANDROID:

                     In this tutorial I will show you how to apply styles for each row item of list view and how to apply different styles for alternative row of list view. 

main.xml:

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

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity" >

    <ListView

  android:id="@+id/listView1"

  android:layout_width="fill_parent"

 android:layout_height="fill_parent"

android:layout_marginLeft="5dp"

android:layout_marginRight="5dp"

android:divider="@null"

android:dividerHeight="0dp"

android:listSelector="@drawable/item_bg" >

    </ListView>

</RelativeLayout>

list_row.xml:

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

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

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:background="@drawable/item_bg"

    android:orientation="vertical" >

    <TextView

        android:id="@+id/textview1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_margin="10dp"

        android:text="Medium Text"

        android:textAppearance="?android:attr/textAppearanceMedium" />

</LinearLayout>

MainActivity:

package com.androidmirror.parthiv;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.Window;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import android.widget.Toast;

public class MainActivity extends Activity {

ListView lv;

String temp[] = { "Parthiv", "Ashok", "Pandian", "Vignesh", "Raguvaran",

"Sreedhar", "Antony", "Kannan", "Amuthan", "Anbu" };

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

setContentView(R.layout.main);

lv = (ListView) findViewById(R.id.listView1);

CustomAdapter adapter = new CustomAdapter(this, temp);

lv.setAdapter(adapter);

}

}

CustomAdapter:

package com.androidmirror.parthiv;

import android.R.color;

import android.app.Activity;

import android.graphics.Color;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.TextView;

import android.widget.Toast;

public class CustomAdapter extends BaseAdapter {

String value[];

Activity context;

public CustomAdapter(Activity context, String[] value) {

super();

this.context = context;

this.value = value;

}

private class ViewHolder {

TextView Name;

}

public int getCount() {

return value.length;

}

public Object getItem(int position) {

return value[position];

}

public long getItemId(int position) {

return 0;

}

@Override

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

final ViewHolder holder;

LayoutInflater inflater = context.getLayoutInflater();

if (convertView == null) {

convertView = inflater.inflate(R.layout.list_row, null);

holder = new ViewHolder();

holder.Name = (TextView) convertView.findViewById(R.id.textview1);

// for alternative layout in list view.

if (position % 2 == 0)

convertView.setBackgroundResource(R.drawable.item_bg);

else {

convertView.setBackgroundResource(R.drawable.item_bg2);

holder.Name.setTextColor(Color.WHITE);

}

convertView.setTag(holder);

} else {

holder = (ViewHolder) convertView.getTag();

}

holder.Name.setText(value[position]);

return convertView;

}

}

SIMPLE STYLE FOR LISTVIEW:

                                                            

  

res/drawable/item_bg.xml:

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

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

    android:dither="true"

    android:shape="rectangle" >

    <gradient android:angle="270" >

    </gradient>

    <stroke

        android:width="5dp"

        android:color="#2e8b57" >

    </stroke>

</shape>

ALTERNATIVE LAYOUT FOR LIST ITEM:

                                         

res/drawable/item_bg2.xml:

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

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

    android:dither="true"

    android:shape="rectangle" >

    <gradient

        android:angle="270"

        android:endColor="#000"

        android:startColor="#000" />

    <stroke

        android:width="5dp"

        android:color="#2e8b57" >

    </stroke>

</shape>
