ListView 的实现步骤
新建数据适配器适配器加载数据源ListView加载适配器为每一个Item添加点击事件适配器分两种：ListAdapter 和SimpleAdapter
案例一：（使用ListAdapter实现ListView（只包含文字哦）） 貌似要先来张照片（这次把图片整小点吧）
布局文件中添加：
<ListView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/main_lv"> </ListView>Activity中
private ListView mListView; private ArrayAdapter<String> mArrayAdapter; mListView=(ListView)findViewById(R.id.main_lv); //1.新建数据适配器 String[] arr={"《上邪》", "Tony-Chen", "上邪,", " 我欲与君相知,", " 长命无绝衰.", " 山无陵,", " 江水为竭.", " 冬雷震震,", " 夏雨雪.", " 天地合,", " 乃敢与君绝."}; //ArrayAdapter(context,当前ListView加载的每一个列表项对应的布局文件，数据源) //2.适配器加载数据源 mArrayAdapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,arr); //3.ListView 加载适配器 mListView.setAdapter(mArrayAdapter);案例一：（使用SimpleAdapter实现ListView（包含图片和文字））
先看看效果：
