Android基本控件高级

ListView  ArrayAdapter和SimpleAdapter

ListView中的setAdapter（） 方法  ListView通过适配器来显示内容的，适配器有两种 一种是ArrayAdapter 另一种是SimpleAdapter

ArrayAdapter是解析一个数组，叫这个数组呈现出ListView效果，注意最后用setConnentView方法将这ListView加入到手机界面进行显示，而Activity本身不用set ConnentView加载本来的main.xml 文件

SimpleAdapter是解析一个List中含有map的集合，这个结构相比一个数组复杂的多，SimpleAdapter解析这个复杂的结构会叫我们可以给客户呈现结构更完美的ListView。

四种Adapter

ArrayAdapter 简单的文字列表

simpleAdapter 自己定义一个丰富的列表

SimpleCursorAdapter可以从数据库中读取数据加到列表上

BaseAdapter可以在列表上加处理事件

实例一：使用ArrayAdapter 作为Listview 适配

MainActivity

package com.example.gdlistviewarrayadapter;

public class MainActivity extends Activity {

private  ListView listview;

private  String data[] ={"周杰伦","佟大为","李小双","文章","范冰冰"};

         @Override

         protected void onCreate(Bundle savedInstanceState) {

                   super.onCreate(savedInstanceState);

                   listview=new ListView(this);

                   // 实例化ListView组件

                   listview.setAdapter(

                                     new ArrayAdapter<String>

                                     (this, android.R.layout.simple_list_item_1, this.data));

                   /*

                    * android.R.layout.simple_list_item_1  是调用系统提供的Id

                    * **/

                   this.setContentView(listview);

                   //设置这个布局

                  

         }

        

}

实例二 SimpleAdapter与List<Map<String ,String >>

MainActivity代码

package com.example.gdlistviewarrayadapter;

public class MainActivity extends Activity {

private  ListView listview;

private  String data[][] ={ { "姓名","周杰伦"},{ "姓名","郭庆雨"}};

private SimpleAdapter  sip;

private List<Map<String ,String>> list = new ArrayList<Map<String,String>>();

   @Override

   protected void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      this.setContentView(R.layout.activity_main);

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

  

   for(int  i=0;i<data.length;i++){

      Map<String ,String > map= new HashMap<String, String>();

        map.put("A", data[i][0]);

        map.put("B", data[i][1]);

        /*

         * map 里面的Key值是随意定义的 只要是和下面的

         * new SimpleAdapter(this,

         * list, R.layout.datalist,

         *  new String[] {"A","B"}, new int[]{R.id._id,R.id.name});

         *  中的 new String[]{}数组里面的数据一样就好

         * **/

        list.add(map);

   }

   sip=

new SimpleAdapter(this,

      list,

      R.layout.datalist, //把模板布局夹到SimpleAdapter中去

  

      new String[] { "A","B"}, new int[]{R.id._id,R.id.name});

   /*

    * new SimpleAdapter(this,

    * list, R.layout.datalist,

    * new String[] {"A","B"}, new int[]{R.id._id,R.id.name});

    *中的new String[]{"A","B"}和 new  int []{R.id._id,R.id.name} 是把 我们的Map中

    *那个key值与我们模板(datalist.xml)布局（layout）中相应的组件布局一一对应

    * **/

  

   listview.setAdapter(this.sip);

   /*new SimpleAdapter(this,

    * list, R.layout.datalist,

    * new String[] {"A","B"}, new int[]{R.id._id,R.id.name});

    *中的   R.layout.datalist, 是把模板布局加到SimpleAdapter中去

    * listview.setAdapter(this.sip)是把SimpleAdapter添加到ListView 中去

    * ListView 又在显示布局（main.xml）中这样模板布局（layout）datalist.xml也同时

    * 被加到显示布局main.xml中去

    * **/

   }

}

activity_main.xml代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <!-- 本布局用于显示布局 -->

    <TextView

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="listView"

        />

    <!-- 用于显示题目 -->

<ListView

    android:id="@+id/list"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

     />

<!-- 本ListView用于加载模板布局datalist.xml -->

</LinearLayout>

datalist.xml 代码

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content" >

    <!-- 注意 用于模板的Layout的高度不能设置沾满整个全屏

    如果沾满了用于显示的Layout将不起作用 -->

    <TableRow >

       

        <TextView

          android:id="@+id/_id"

          android:layout_width="wrap_content"

          android:layout_height="wrap_content"

           

             />

        <TextView

            android:id="@+id/name"

            android:layout_height="wrap_content"

             />

    </TableRow>

</TableLayout>

ListActivity

对话框Dialog和Dialog.Builder

Dialog extends Object的子类AlertDialog和CharacterPickerDialog

AlertDialog extends Dialog的子类DataPickerDialog,ProgressDialog和TimePickerDialog

AlertDialog.Builder不是AlertDialog的子类而是AlertDialog的嵌套类，

Public  void class  AlertDialog extends Dialog{

Pubic static class AlertDialog.Builder extends Object{

}

}

在图形界面中，对话框也是人机交互的一种重要形式，程序可以通话对话框对用户进行一些信息的提示

，而用户也可以通过对话框和程序进行一些简单的交互操作，Dialog 可以有一个按钮或是多个按钮或是列表选项，进行人家交互。

在android的开发中，所有的对话框都是从android.app.Dialog 类继承而来，此类的继承机构如下

Java.Long.Object

          Android.app.Dialog

可以看出，此类直接继承自Object类，与View类没有任何继承关系。

但是如果要想实例化，AlertDialog类，往往要依靠其内部类，AlertDialog.Builder完成，在AlertDialog.Builder

类中定义的常用方法如下表

Dialog类定义的常用方法

NO	方      法	类   型	描        述

   @Override

   protected void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      setContentView(R.layout.activity_main);

      mybut=(Button)findViewById(R.id.mybut);

      show=(TextView)findViewById(R.id.show);

      mybut.setOnClickListener(new SetSingleChoice());

   }

   class  SetSingleChoice implements  OnClickListener{

      @Override

      public void onClick(View arg0) {

        // TODO Auto-generated method stub

        AlertDialog.Builder  builder = new AlertDialog.Builder(MainActivity.this);

          builder.setIcon(R.drawable.ic_launcher);

          builder.setTitle("选择你喜欢的水果");

          builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {

          

           @Override

           public void onClick(DialogInterface dialog, int which) {

              // TODO Auto-generated method stub

              MainActivity.this.show.setText("你喜欢的水果是："+MainActivity.this.fruitData[chNum]);

           }

        });

          builder.setNegativeButton("取消",  new DialogInterface.OnClickListener() {

          

           @Override

           public void onClick(DialogInterface dialog, int which) {

              // TODO Auto-generated method stub

        });

         builder.setSingleChoiceItems(MainActivity.this.fruitData, 0, new  DialogInterface.OnClickListener() {

   /*

   * setSingleChoiceItems(
