spinner 下拉选择控件

1、创建XML文件

<?xml version="1.0" encoding="utf-8"?>
<Spinner xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@+id/idspinner"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content">
    <Spinner android:id="@+id/idspinner1"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content">>
    </Spinner>
</Spinner>

2、新创建一个Activtiy文件

package com.example.jj;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.Spinner
/**
 * Created by Administrator on 14-11-25.
 */
public class Actitiy_spinner extends Activity {

//定义属性
    private Spinner mspinner;
           private String[] array=new String[]{"后悔","传达出","对错"};
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.spinner_xml);
//初始化属性
            mspinner=(Spinner)findViewById(R.id.idspinner);
//绑定Adapter
            ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,array);
            mspinner.setAdapter(adapter);
    }
}
