Android 下拉列表Spinner 使用

1、布局文件

<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" tools:context="com.example.helloword.DropListActivity" > <Spinner android:id="@+id/spinner1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:entries="@array/ctype" /> <Spinner android:id="@+id/spinner2" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout>

2、arrays.xml

 

 

<?xml version="1.0" encoding="utf-8"?> <resources> <string-array name="ctype"> <item>全部</item> <item>电影</item> <item>书籍</item> <item>体育</item> <item>文娱</item> <item>生活</item> </string-array> </resources>

3、Activity

package com.example.helloword; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.Spinner; public class DropListActivity extends Activity implements View.OnClickListener{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_drop_list); String[] arrayStrings = new String[]{"全部","海贼王","火影忍者","龙珠"}; ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,arrayStrings); adapter.setDropDownViewResource(android.R.layout.simple_spinner_item); Spinner spinner = findViewById(R.id.spinner2); spinner.setAdapter(adapter); } @Override public void onPointerCaptureChanged(boolean hasCapture) { // TODO Auto-generated method stub } @Override public void onClick(View arg0) { // TODO Auto-generated method stub } }
