------------------------------------------------Spinner的简单用法(ArrayAdapter)--------------------------------------

1.布局文件定义一个是spinner

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"
    android:padding="5dp"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="选择您的排位分段"
        android:textColor="#44BDED"
        android:textSize="18sp" />

    <Spinner
        android:id="@+id/spin_one"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:entries="@array/data"
        android:spinnerMode="dialog" />


</LinearLayout>

 2.Activity初始化Spinner

package com.example.spinnerdemo;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.ArrayAdapter;
import android.widget.Spinner;

public class MainActivity extends Activity {

    @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Spinner spinner=(Spinner) findViewById(R.id.spin_one);
        List<String> list = new ArrayList<String>();
        list.add("选项1");
        list.add("选项3");
        list.add("选项2");
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,list);
        spinner.setAdapter(adapter);


    }

    @Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
return true;
    }

}

如果页面中不初始化list。

定义一个数组文件:

myarrays.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

<string-array name="data">
<item>英勇青铜</item>
<item>不屈白银</item>
<item>荣耀黄金</item>
<item>华贵铂金</item>
<item>璀璨钻石</item>
<item>超凡大师</item>
<item>最强王者</item>
</string-array>

</resources>

 

页面效果:

 

 

 

---------------------------ListView的简单用法(SimpleAdapter)--------------------------------

1.布局文件：

android:spinnerMode="dialog"可以修改打开方式

<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"
    android:padding="5dp"
    tools:context=".MainActivity">

<TextView
android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="选择您的排位分段"
        android:textColor="#44BDED"
        android:textSize="18sp" />

<Spinner
android:id="@+id/spin_one"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:entries="@array/data"
        android:spinnerMode="dialog" />


<!-- 添加一个ListView控件 -->
<ListView
android:id="@+id/lv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
/>


</LinearLayout>

 

item.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<ImageView
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/ItemImage"
/>
<TextView
android:id="@+id/ItemTitle"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:textSize="20sp"
/>
<TextView
android:id="@+id/ItemText"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_below="@+id/ItemTitle"
/>
</RelativeLayout>

 

 

 

 

2.Activity代码:(图片要放在目录)

package com.example.spinnerdemo;

import java.util.ArrayList;
import java.util.HashMap;

import android.app.Activity;
import android.os.Bundle;
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 Activity {

private ListView lv;

/** Called when the activity is first created. */
     @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
             setContentView(R.layout.activity_main);

     lv = (ListView) findViewById(R.id.lv);
/*定义一个动态数组*/
      ArrayList<HashMap<String, Object>> listItem = new ArrayList<HashMap<String,Object>>();
/*在数组中存放数据*/
for(int i=0;i<5;i++)  
             {  
                 HashMap<String, Object> map = new HashMap<String, Object>();  
                 map.put("ItemImage", R.drawable.ic_launcher);//加入图片
                 map.put("ItemTitle", "第"+i+"行");  
                 map.put("ItemText", "这是第"+i+"行");  
                 listItem.add(map);  
             } 

     SimpleAdapter mSimpleAdapter = new SimpleAdapter(this,listItem,//需要绑定的数据
             R.layout.item,//每一行的布局
//动态数组中的数据源的键对应到定义布局的View中
new String[] {"ItemImage","ItemTitle", "ItemText"},new int[] {R.id.ItemImage,R.id.ItemTitle,R.id.ItemText});

     lv.setAdapter(mSimpleAdapter);//为ListView绑定适配器

     lv.setOnItemClickListener(new OnItemClickListener() {

                 @Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
                     setTitle("你点击了第"+arg2+"行");//设置标题栏显示点击的行
                     
                 }
             });
         }
     }
