Question

我有一个疑问。我有一个包含autocompletetextview的活动.autoocompletetextview的内容已在strings.xml文件中声明为字符串数组。我在strings.xml文件中还有一个字符串数组。我想要什么就是当我从autocompletetextview中选择一个项目时，它应该以toast的形式从第二个字符串数组中显示一个值。这是可能的.Plz帮帮我

Answer 1

适用于Array ::

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

For String ::

String myString =getResources().getString(R.string.str);

Answer 2

检查，

package mytest.projects;

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

public class example extends ListActivity {
String[] mTestArray;

/** 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;

    mTestArray =  = getResources().getStringArray(R.array.testArray);    

    /* Assign the name array to that adapter and 
    also choose a simple layout for the list items */ 
    adapter = new ArrayAdapter<String>(
    this,
    android.R.layout.simple_list_item_1,
    mTestArray);

    // Assign the adapter to this ListActivity
    setListAdapter(adapter);
    }
}

从strings.xml中提取值
