Adapter系列之ArrayAdapter

Adapter系列之ArrayAdapter

ArrayAdapter:简单、易用的Adapter,通常用于将List集合的多个值包装成多个列表项。

使用ArrayAdapter创建ListView
activity_main.xml文件:

<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/list1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:divider="#f00" android:dividerHeight="2px" android:headerDividersEnabled="false"/>
    <ListView android:id="@+id/list2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:divider="#0f0" android:dividerHeight="2px" android:headerDividersEnabled="false"/>

</LinearLayout>

item01文件:

<?xml version="1.0" encoding="utf-8"?>
 <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tv" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="24dp" android:padding="10px" android:textColor="#00f"/>

item02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" >

     <TextView android:id="@+id/tv2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="24dp" android:padding="10px" android:textColor="#00f"/>

</LinearLayout>

MainActivity文件

package com.example.arrayadaptertest;

import android.app.Activity;
import android.os.Bundle;
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);

        ListView list01 = (ListView) findViewById(R.id.list1);
        String[] arr1 = {
                "我欲乘风来",
                "除魔天地间",
                "有酒我逍遥"
                };
        ArrayAdapter<String>adapter01 = new ArrayAdapter<String>(this, R.layout.item01, arr1);
        list01.setAdapter(adapter01);


        ListView list02 = (ListView) findViewById(R.id.list2);
        String[] arr2 = {
                "Java",
                "C++",
                "JavaScript"
        };
        ArrayAdapter<String>adapter02 = new ArrayAdapter<String>(this,
                R.layout.item02, R.id.tv2, arr2);
        list02.setAdapter(adapter02);

    }

}
