Android－ListView 学习笔记

1.XML：‘

拖一个ListView 控件到屏幕中，XML代码如下

<ListView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/listView" android:layout_centerVertical="true" android:layout_centerHorizontal="true" /> 2使用ArrayAdapter适配器实现ListView的显示

//定义一个数组来显示ListView 的内容 private static final String[] strs = new String[] {"初级控件","GridView","spinner","gallery","ScrollView","RecyclerView","Dialog","BlockquoteAlertDialog","DatePickerDialog","Menu"}; private ListView lv; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); lv = (ListView)findViewById(R.id.listView); //第一个参数为上下文,第二个参数可以自定义一个layout.但是这个layout必须要有TextView,第三个参数为listView的内容 lv.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,strs)); } 3.使用多选模式

lv.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_checked,strs)); //或者lv.setAdapter(<span style="color:#0000ff;margin: 0px; padding: 0px; line-height: 1.5;">new</span> ArrayAdapter<String>(<span style="color:#0000ff;margin: 0px; padding: 0px; line-height: 1.5;">this</span>, <pre> android.R.layout.simple_list_item_multiple_choice, strs)); lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

4.使用单选模式

lv.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_single_choice,strs)); lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);//是否单选主要还是有Mode决定 

5.点击事件：

lv.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { //点击后输出点击了第几行 Log.d("1","你点击了第"+arg2+"行"); } });
