我正在开发一个项目,其中我有一个listview,我的代码中有几个数组,但我想从一个单独的xml文件加载数组,这是“strings.xml”
但我无法弄明白该怎么做
这是我的活动
package com.Example.myapk;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
public class MainActivity extends Activity {
private ListView list1;
private String array[] = { "Iphone", "Tutorials", "Gallery", "Android",
"item 1", "item 2", "item3", "item 4", "item 1", "item 2", "item3", "item 4","item 1", "item 2", "item3", "item 4"};
EditText inputSearch;
ArrayAdapter<String> adapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inputSearch = (EditText) findViewById(R.id.inputSearch);
list1 = (ListView) findViewById(R.id.listView01);
adapter =new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, array);
list1.setAdapter(adapter);
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
MainActivity.this.adapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});
list1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent myIntent = new Intent(MainActivity.this,WebViewActivity.class);
myIntent.putExtra("key",position);
startActivity(myIntent);
}
});
}
}

将以下代码放在string.xml中
<string-array name="myArray">
<item >Iphone</item>
<item >Tutorials</item>
<item >Gallery</item>
<item >Android</item>
<item >item 1</item>
</string-array>
然后getResources().getStringArray(R.array.myArray)
将这些值作为字符串数组返回。所以在你的主要活动文件中
private ListView list1;
private String array[] = getResources().getStringArray(R.array.myArray);
EditText inputSearch;
ArrayAdapter<String> adapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inputSearch = (EditText) findViewById(R.id.inputSearch);
list1 = (ListView) findViewById(R.id.listView01);
adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, array);
list1.setAdapter(adapter);
}

要将数组存储在xml中,您可以执行以下操作:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="myArray">
<item>Iphone</item>
<item>Tutorials</item>
<item>Gallery</item>
<item>Android</item>
</string-array>
</resources>
然后在您的代码中,您可以访问它:
Resources res = getResources();
String[] myArray = res.getStringArray(R.array.myArray);
