主Activity布局檔案(activity_main.xml)

<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:orientation="vertical" >    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="#03fb2c"        android:padding="24px" >        <TextView            android:id="@+id/textView1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerInParent="true"            android:text="Listview"            android:textSize="48px" />    </RelativeLayout>    <ListView           android:id="@+id/bookmark_ListView"          android:layout_gravity="center"          android:layout_width="wrap_content"          android:layout_height="fill_parent"        android:background="#FFFFA0" >      </ListView>    </LinearLayout>

自訂ListView布局檔案(list_item_simple.xml)

<?xml version="1.0" encoding="UTF-8"?><LinearLayout    android:id="@android:id/text1"    xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="horizontal"    android:layout_width="match_parent"    android:layout_height="match_parent">    <ImageView        android:id="@+id/BookMark_list_item_simple_favicon"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="@drawable/browser_net"/>    <TextView         android:id="@+id/BookMark_list_item_simple_text"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_weight="1"        android:layout_gravity="center"        android:textSize="36px"        android:ellipsize="end"          android:singleLine="true"/></LinearLayout>

MainActivity.java

package com.example.arrayadapterlistviewdemo;import java.util.ArrayList; import android.os.Bundle;import android.app.Activity; import android.view.View;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.AdapterView.OnItemLongClickListener;import android.widget.ArrayAdapter;import android.widget.ListView;import android.widget.Toast;public class MainActivity extends Activity {    private ListView mListView;    private MyArrayAdpter mAdpter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);        ArrayList<String> mList = new ArrayList<String>();        mList.add("aaaaaaaaaaaaaa");        mList.add("bbbbbbbbbbbbbb");        mList.add("cccccccccccccc");           mAdpter = new MyArrayAdpter(this, mList);        mListView = (ListView) findViewById(R.id.bookmark_ListView);        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,mList);         mListView.setAdapter(adapter);        mListView.setOnItemLongClickListener(new OnItemLongClickListener() {            @Override            public boolean onItemLongClick(AdapterView<?> arg0, View arg1,                    int arg2, long arg3) {                // TODO Auto-generated method stub                mListView.setAdapter(mAdpter);                return false;            }        });        mListView.setOnItemClickListener(new OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,                    long arg3) {                // TODO Auto-generated method stub                Toast.makeText(MainActivity.this, "第"+arg2+"點擊事件發生", Toast.LENGTH_LONG).show();            }        });    }}

自訂ArrayAdapter適配器

package com.example.arrayadapterlistviewdemo;import java.util.ArrayList;  import android.content.Context;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.widget.ArrayAdapter;import android.widget.ImageButton;import android.widget.ImageView;import android.widget.TextView;import android.widget.Toast;public class MyArrayAdpter extends ArrayAdapter<String>{    private Context mContext;    private ArrayList<String> mList = new ArrayList<String>();    public MyArrayAdpter(Context context, ArrayList<String> list) {        super(context, android.R.layout.simple_list_item_checked,list);        // TODO Auto-generated constructor stub         mContext = context;         mList = list;      }    @Override    public void add(String object) {        // TODO Auto-generated method stub//      super.add(object);        mList.add(object);    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        // TODO Auto-generated method stub        final int mPosition = position;        if (null == convertView) {             convertView = ((MainActivity) mContext).getLayoutInflater()                        .inflate(R.layout.list_item_simple, null);        }        TextView textView =(TextView)convertView.findViewById(R.id.BookMark_list_item_simple_text);         textView.setText(mList.get(position));         ImageView mImage = (ImageView) convertView.findViewById(R.id.BookMark_list_item_simple_favicon);        mImage.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View arg0) {                // TODO Auto-generated method stub                Toast.makeText(mContext, "第"+mPosition+"表徵圖被點擊", Toast.LENGTH_LONG).show();            }        });        return convertView;    }}
