创建ListView的基本步骤

参考《疯狂android讲义》第2.5节P94

1、创建一个或者多个ListView

 

<LinearLayout 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"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    android:orientation="vertical"

    tools:context=".MainActivity" >

    

    <ListView 

        android:id="@+id/list1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:divider="#f00"

        android:dividerHeight="2dp"

        android:headerDividersEnabled="false" />

    

        <ListView 

        android:id="@+id/list2"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:divider="#0f0"

        android:dividerHeight="2dp"

        android:headerDividersEnabled="true" />

</LinearLayout>

2、创建TextViewResource，为每个元素定义其显示属性

 

array_item1.xml

 

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

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

    android:id="@+id/tv_item1"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:textSize="20sp"

    android:padding="10dp"

    android:shadowColor="#0f0"

    android:shadowDx="4"

    android:shadowDy="4"

    android:shadowRadius="2">

</TextView>

array_item2.xml

 

 

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

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

    android:id="@+id/tv_item2"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:textSize="20sp"

    android:padding="10dp"

    android:shadowColor="#ff0"

    android:shadowDx="4"

    android:shadowDy="4"

    android:shadowRadius="2">

</TextView>

3、创建Activity，并完成以下三个步骤

 

 

package com.ljh.listviewdemo;



import android.os.Bundle;

import android.app.Activity;

import android.widget.ArrayAdapter;

import android.widget.ListView;



public class MainActivity extends Activity {



	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.activity_main);

		

		//3、定义每个元素的内容

		String[] arr1 = new String[]{"孙悟空","猪八戒","沙僧","唐僧"};

		

		//4、将元素属性及元素内容包装为ArrayAdapter

		ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this, R.layout.array_item1, arr1);

		

		//5、为ListView设置Adapter

		ListView list1 = (ListView) findViewById(R.id.list1);

		list1.setAdapter(adapter1);

		

		//3、定义每个元素的内容

		String[] arr2 = new String[]{"Java","C++","Python","PHP"};

		

		//4、将元素属性及元素内容包装为ArrayAdapter

		ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this, R.layout.array_item2, arr2);

		

		//5、为ListView设置Adapter

		ListView list2= (ListView) findViewById(R.id.list2);

		list2.setAdapter(adapter2);

	}

	

}
