Simple SimpleAdapter and simpleadapter for Android

SimpleAdapter is the most basic and commonly used. Although you can implement your own adapter (baseadapter, etc.), it is complicated and unnecessary.

package com.cn.demo05vitamio;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import android.content.Intent;import android.os.Bundle;import android.support.v7.app.ActionBarActivity;import android.view.View;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.ListView;import android.widget.SimpleAdapter;public class MainActivity extends ActionBarActivity {private ListView lView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);lView = (ListView)findViewById(R.id.list);lView.setAdapter(new SimpleAdapter(this, getdata(), R.layout.mylist_item,new String[]{"title",}, new int[]{R.id.text1}));lView.setOnItemClickListener(new OnItemClickListener() {@SuppressWarnings("unchecked")@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {Map<String, Object> map = (Map<String, Object>)parent.getItemAtPosition(position);Intent intent =(Intent)map.get("intent");startActivity(intent);}});}private List<Map<String, Object>> getdata() {List<Map<String, Object>> myData = new ArrayList<Map<String,Object>>();addItem(myData,"title01",new Intent(this, Demo01.class));addItem(myData,"ttile02",new Intent(this, Demo02.class));return myData;}private void addItem(List<Map<String, Object>> myData, String string,Intent intent) {Map<String, Object> map = new HashMap<String, Object>();map.put("title", string);map.put("intent", intent);myData.add(map);}}

You can customize the layout file R. layout. mylist_item.
