Already I have written articles about ListView, it’s about
to context menu using in listview.
Here I would share the method to use display two items in
List View.
For display Single item in ListView we use array adapter, to
display multiple items in List View, we use simple adapter.
Below I clearly depict to use the step by step method to use
multiple items in ListView.
Step 1:
First create a layout to use in list view, with respect to the
display items must add the textview,Here I would display two items and one
image in list view, so I added two TextView and image .
rowlayout.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:orientation="horizontal"
android:paddingTop="20dp">
<ImageView
android:id="@+id/icon"
android:layout_width="22dp"
android:layout_height="22dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="10dp"
android:layout_marginTop="4dp"
android:src="@drawable/man" >
</ImageView>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+id/label"
android:textSize="12sp"
android:textStyle="bold"
android:textColor="#000000">
</TextView>
<TextView
android:id="@+id/label1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:textStyle="italic"
android:typeface="sans"
android:textColor="#000000">
</TextView>
</LinearLayout>
</LinearLayout>

Add ListView in activity layout
List.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:orientation="vertical">
<ListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
>
</ListView>
</LinearLayout>
|
Step 3:
Here use the java code to set the data in ListView.By using
Hashmap string we set two arrays string str and country in List View.
|
package de.dotnetcode.android.list;
import
java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
import
android.app.Activity;
import android.os.Bundle;
import
android.widget.SimpleAdapter;
public class Mylist extends Activity {
String[] str,country;
ListView lst;
protected void onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list);
str=new String[] {"Kumar","Rajesh","Daliel","Salim","Mohammed"};
country=new String[] {"India","Japan","Singapore","USA","UK"};
lst = (ListView)
findViewById(R.id.listView1);
ArrayList<HashMap<String,
String>> mylistData =
new
ArrayList<HashMap<String, String>>();
String[] row = new String[] {"row1", "row2"};
for(int i=0;i < str.length; i++)
{
HashMap<String,String> map = new HashMap<String,
String>();
//initialize row data
map.put("row1",str[i]);
map.put("row2", country[i]);
mylistData.add(map);
}
SimpleAdapter arrayAdapter =
new SimpleAdapter(this, mylistData,
R.layout.rowlayout,
row , new int[] {R.id.label,R.id.label1});
lst.setAdapter(arrayAdapter);
}
}

I hope the example would help you to understand the ListView
process..
Incase if you have any doubts or any issues to implement the
method. Please post your comments here…
