一、使用方法
1、在layout中创建Spinner控件
<Spinner android:id="@+id/spinner1" android:layout_width="match_parent" android:layout_height="wrap_content" />
2、给数据适配器添加数据源和显示格式
String[] city=new String[]{"北京","上海","香港","澳门"};
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_dropdown_item, city);
3、给Spinner控件添加数据适配器
spinner1.setAdapter(adapter);
二、效果图及代码
fry.Activity01
package fry;
import com.example.SpinnerDemo.R;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
public class Activity01 extends Activity{
private Spinner spinner1;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity01);
spinner1=(Spinner) findViewById(R.id.spinner1);
initSpinner1();
}
public void initSpinner1(){
String[] city=new String[]{"北京","上海","香港","澳门"};
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, city);
spinner1.setAdapter(adapter);
}
}
/SpinnerDemo/res/layout/activity01.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Spinner
android:id="@+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
