首先在xml里面加一个Spinner控件
<RelativeLayout 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" tools:context="${packageName}.${activityClass}" > <Spinner android:id="@+id/sp" android:layout_width="match_parent" android:layout_height="wrap_content" /> </RelativeLayout>
然后再加一个Spinner的item的xml,里面设置每一列的效果,名字叫:spitem.xml
<?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/text1" style="?android:attr/spinnerDropDownItemStyle" android:layout_width="match_parent" android:layout_height="40sp" android:textSize="30sp" android:background="#FFFFFF" android:singleLine="true" />
最后在代码中加载Spinner
import android.app.Activity; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.Spinner; public class MainActivity extends Activity { Spinner spinner; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); spinner=(Spinner)findViewById(R.id.sp); String data[]=new String[]{"a","b","c"}; //声明一个ArrayAdaper,用来装载Spinner数据 ArrayAdapter<String>adapter=new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, data); //加载item的布局样式 adapter.setDropDownViewResource(R.layout.spitem); //最后让Spinner加载adapter spinner.setAdapter(adapter); } }
