我只是想从我的数组中显示一个列表arrays.xml.当我尝试在模拟器中运行它时,我收到强制关闭消息.

如果我在java文件中定义数组

String[] testArray = new String[] {"one","two","three","etc"};

它有效,但是当我使用时

String[] testArray = getResources().getStringArray(R.array.testArray);

它不起作用.

这是我的Java文件:

package com.xtensivearts.episode.seven;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class Episode7 extends ListActivity {
 String[] testArray = getResources().getStringArray(R.array.testArray);

 /** Called when the activity is first created. */
 @Override
 protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  // Create an ArrayAdapter that will contain all list items
  ArrayAdapter<String> adapter;

  /* Assign the name array to that adapter and 
     also choose a simple layout for the list …

下面是我检索字符串数组项的代码:

String[] menuArray;

@Override
public void onCreate(Bundle savedInstanceState) 
{       
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ScrollView sv = new ScrollView(this);
    LinearLayout ll = new LinearLayout(this);
    ll.setOrientation(LinearLayout.VERTICAL);
    sv.addView(ll);

 // Create an ArrayAdapter that will contain all list items
    ArrayAdapter<String> adapter;

    menuArray = getResources().getStringArray(R.array.menu); 


    for(int i = 0; i < menuArray.length; i++) 
    {
        Button b = new Button(this);
        b.setText(menuArray[i]);
        ll.addView(b);
    }

    this.setContentView(sv);
 }

这是strings.xml文件:

 <string-array name="menu">
        <item>1</item>
        <item>2</item>
        <item>3</item>
        </string-array>

但是,编译此问题的R.array.menu:从ADT 14开始,资源字段不能用作切换案例.调用此修复程序以获取更多信息.
