42.Android之ListView中ArrayAdapter简单学习

时间：2022-09-05 07:33:23

今天学习下Android中ListView关于ArrayAdapter数据绑定, 废话少说直接上代码。

改下布局文件：

 <?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/lv1"

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:layout_weight="1">

     </ListView>

      <ListView

         android:id="@+id/lv2"

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:layout_weight="1">

     </ListView>

       <ListView

         android:id="@+id/lv3"

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:layout_weight="1" >

     </ListView>

         <ListView

         android:id="@+id/lv4"

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:layout_weight="1" >

     </ListView>

 </LinearLayout>

代码修改：

 package com.example.listviewarraydemo;

 import android.app.Activity;

 import android.os.Bundle;

 import android.widget.ArrayAdapter;

 import android.widget.ListView;

 public class MainActivity extends Activity {

     private ListView listView = null;

     private ListView listView_two = null;

     private ListView listView_three = null;

     private ListView listView_four = null;

     ArrayAdapter<String> adapter1;

     ArrayAdapter<String> adapter2;

     ArrayAdapter<String> adapter3;

     ArrayAdapter<String> adapter4;

     private static final String[] strs = {"one item","two item","three item","four item"};

     private static final String[] strs_two = {"1111","2222","3333","4444"};

     private static final String[] strs_three = {"AAAA","BBBB","CCCC","DDDD"};

     private static final String[] strs_four = {"yuwen","shuxue","yingyu","tiyu"};

     @Override

     protected void onCreate(Bundle savedInstanceState) {

         super.onCreate(savedInstanceState);

         setContentView(R.layout.activity_main);

         listView = (ListView)findViewById(R.id.lv1);

         listView_two = (ListView)findViewById(R.id.lv2);

         listView_three = (ListView)findViewById(R.id.lv3);

         listView_four = (ListView)findViewById(R.id.lv4);

         adapter1 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,strs);

         adapter2 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_checked,strs_two);

         adapter3 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_multiple_choice,strs_three);

         adapter4 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_single_choice,strs_four);

         listView.setAdapter(adapter1);

         listView_two.setAdapter(adapter2);

         listView_two.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

         listView_three.setAdapter(adapter3);

         listView_three.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

         listView_four.setAdapter(adapter4);

         listView_four.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

     }

 }

一些代码说明：

ListView自身带了单选、多选模式，可通过listview.setChoiceMode来设置：
listview.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);//开启多选模式
listview.setChoiceMode(ListView.CHOICE_MODE_SINGLE);//开启单选模式

运行效果：
