Android 搜索 Activity 未启动

Question

当我按下 Android 手机上的搜索按钮时，我的搜索框没有显示。我想要做的是执行 ASyncTask(或后台任务)以获取字符串数组(人名)的 JSON 响应，搜索结果，并使用 IMDB 具有的相同搜索功能将其显示给用户。目前，我正在使用字符串数组来测试我的搜索响应/请求。有什么想法吗？

我在按下搜索按钮时收到以下警告(但我认为这与我的问题无关):

04-21 03:35:23.767: WARN/KeyCharacterMap(12946): Can't open keycharmap file

The error below has been fixed courtesy of @Heiko Rupp:

04-21 03:17:51.994: WARN/SearchableInfo(1293): Invalid searchable metadata for com.redacted/.SearchActivity: Search label must be a resource reference.

SearchActivity.java:

package com.redacted;

import android.app.ListActivity;
import android.app.SearchManager;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class SearchActivity extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.search_results);
        handleIntent(getIntent());
    }

    @Override
    protected void onNewIntent(Intent intent) {
        setIntent(intent);
        handleIntent(intent);
    }

    private void handleIntent(Intent intent) {
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            showResults(query);
        }
    }

    private void showResults(String q) {
        String[] listItems = { "test", "my", "search", "list" };

        setListAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, listItems));
    }
}

searchable.xml:

<?xml version="1.0" encoding="utf-8"?>
<searchable
  xmlns:android="http://schemas.android.com/apk/res/android" 
  android:searchButtonText="Search" 
  android:label="Redacted" 
  android:hint="Redacted"
  android:voiceSearchMode="showVoiceSearchButton|launchRecognizer">
</searchable>

Manifest Manifest.xml 的一部分(元数据在标签内，因此它是全局的):

<activity android:launchMode="singleTop" android:name="SearchActivity">
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>
            <meta-data android:name="android.app.searchable" 
                android:resource="@xml/searchable"/>
        </activity>
        <meta-data android:name="android.app.default_searchable"
            android:value="SearchActivity" />
    </application>

search_results.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <ListView android:layout_height="wrap_content" android:layout_width="match_parent" android:id="@+id/list"></ListView>
</LinearLayout>

我遇到了同样的问题。android:label 的值必须是字符串资源。硬编码字符串不会起作用。
