SimpleAdapter的使用

Activity_main.xml:

    <ListView

       android:id="@+id/listview"

       android:layout_width="fill_parent"

       android:layout_height="wrap_content"

        />

View.xml:

    <TextView

       android:id="@+id/textview1"

       android:layout_width="fill_parent"

       android:layout_height="wrap_content"

        />

    <TextView

       android:id="@+id/textview2"

       android:layout_width="fill_parent"

       android:layout_height="wrap_content"

        />

MainActivity.java:

package leihu.simpleadapter;

 
import java.util.ArrayList;

import java.util.HashMap;

import android.os.Bundle;

import android.app.Activity;

import android.widget.ListView;

import android.widget.SimpleAdapter;


public class MainActivity extends Activity {

    /** Called when the activity is first created. */

    ListView listview = null;

    SimpleAdapter adapter = null;

    ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();

    @Override

    public void onCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);

       setContentView(R.layout.activity_main);

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

       // 注意点android.R.layout.simple_list_item_2用的android自带的layout，那么new

       // int[]{android.R.id.text1,android.R.id.text2}也必须用android中的控件，自定义的layout不能和android中自带的控件混用。

        adapter = new SimpleAdapter(this,list,android.R.layout.simple_list_item_2,new

        String[]{"text2","text1"},new

        int[]{android.R.id.text1,android.R.id.text2});

        //这里使用的是android自带的layout和TextView控件

 

       //adapter = new SimpleAdapter(this, list, R.layout.view,

       //     new String[] {"text2", "text1" },

       //     new int[] { R.id.textview1, R.id.textview2 });// 这里使用的自定义的layout和TextView控件

       getList();

       listview.setAdapter(adapter);

    }

 

    public void getList() {

       HashMap<String, String> map1 = new HashMap<String, String>();

       map1.put("text1", "pfg");

       map1.put("text2", "lhy");

 

       HashMap<String, String> map2 = new HashMap<String, String>();

       map2.put("text1", "hyt");

       map2.put("text2", "grp");

 

       HashMap<String, String> map3 = new HashMap<String, String>();

       map3.put("text1", "klt");

       map3.put("text2", "dfg");

 

       HashMap<String, String> map4 = new HashMap<String, String>();
