ANDROID – SIMPLE LISTVIEW USING SIMPLEADAPTER

In Android Applications, ListView helps you to display the contents of an array with flexible size. The following example shows you how to create a simple ListView.

1. First create a new Android project

2. Create the following Java class

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

import java.util.ArrayList; import java.util.HashMap; import java.util.List;   import android.app.Activity; import android.os.Bundle; import android.widget.ListView; import android.widget.SimpleAdapter;   public class ListViewA extends Activity {     /** Called when the activity is first created. */     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);         ListView lv= (ListView)findViewById(R.id.listview);           // create the grid item mapping         String[] from = new String[] {"rowid", "col_1", "col_2", "col_3"};         int[] to = new int[] { R.id.item1, R.id.item2, R.id.item3, R.id.item4 };           // prepare the list of all records         List<HashMap<String, String>> fillMaps = new ArrayList<HashMap<String, String>>();         for(int i = 0; i < 10; i++){             HashMap<String, String> map = new HashMap<String, String>();             map.put(from[0], "" + i);             map.put(from[1], "col_1_item_" + i);             map.put(from[2], "col_2_item_" + i);             map.put(from[3], "col_3_item_" + i);             fillMaps.add(map);         }           // fill in the grid_item layout         SimpleAdapter adapter = new SimpleAdapter(this, fillMaps, R.layout.grid_item, from, to);         lv.setAdapter(adapter);     } }

 

 3. Create the following 2 layouts

main.xml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56

<?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/main"     xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_height="fill_parent"     android:layout_width="fill_parent">     <!-- Header -->     <LinearLayout android:id="@+id/header"         android:background="#ff347c12"         android:layout_height="wrap_content"         android:layout_width="fill_parent"         >         <TextView android:id="@+id/item1"             android:layout_height="fill_parent"             android:layout_width="wrap_content"             android:width="20dip"             android:height="30dip"         />         <TextView android:id="@+id/item2"             android:layout_height="fill_parent"             android:layout_width="wrap_content"             android:text="col_1_h"             android:width="100dip"             android:height="30dip"         />         <TextView android:id="@+id/item3"             android:layout_height="fill_parent"             android:layout_width="wrap_content"             android:text="col_2_h"             android:width="100dip"             android:height="30dip"         />         <TextView android:id="@+id/item4"             android:layout_height="fill_parent"             android:layout_width="wrap_content"             android:text="col_3_h"             android:width="100dip"             android:height="30dip"         />     </LinearLayout>       <!-- List Divider -->     <View android:layout_width="fill_parent"         android:layout_height="1dip"         android:background="?android:attr/listDivider" />       <!-- ListView (grid_items) -->     <LinearLayout android:id="@+id/layout"         android:layout_width="wrap_content"         android:layout_height="fill_parent">         <ListView android:id="@+id/listview"             android:layout_height="fill_parent"             android:layout_width="fill_parent">         </ListView>     </LinearLayout> </LinearLayout>

 

 

grid_item.xml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="horizontal"     android:layout_width="fill_parent"     android:layout_height="fill_parent">         <TextView android:id="@+id/item1"             android:text="row_id"             android:layout_height="fill_parent"             android:layout_width="wrap_content"             android:width="20dip"         />         <TextView android:id="@+id/item2"             android:text="col_1"             android:layout_height="fill_parent"             android:layout_width="wrap_content"             android:width="100dip"         />         <TextView android:id="@+id/item3"             android:text="col_2"             android:layout_height="fill_parent"             android:layout_width="wrap_content"             android:width="100dip"         />         <TextView android:id="@+id/item4"             android:text="col_3"             android:layout_height="fill_parent"             android:layout_width="wrap_content"             android:width="100dip"         /> </LinearLayout>
