如何调用使用onSearchRequested搜索对话框（） [英] How do I invoke the search dialog using onSearchRequested()

问题描述

我想实现的搜索对话框，我无法显示从活动搜索。

I'm trying to implement the search dialog and I am unable to display the search from an Activity.

我在清单文件我的主要活动定义，本次活动展示了用户，他们有可供选择的选项列表。其中一个选项是一个搜索选项。

I have my main activity defined in my manifest file, this activity shows the user a list of options they have to choose from. One of the options is a Search option.

    <activity
        android:name=".MenuListActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

我的搜索活动在我的清单文件中定义如下。

My Search activity is defined in my manifest file like so.

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

现在我的问题是，当我从我的MenuListActivity什么也没发生调用onSearchRequested（）。

Now my problem is when I call the onSearchRequested() from my MenuListActivity nothing happens.

public void onItemClick(AdapterView<?> parent, View itemClicked, int position, long id) {  
          String strText = items[position];  

          if (strText.equalsIgnoreCase(getResources().getString(R.string.menu_item_browse))) {  
              startActivity(new Intent(MenuListActivity.this, WSMobileActivity.class));  
          } else if (strText.equalsIgnoreCase(getResources().getString(R.string.menu_item_search))) { 

            // If i call it like this it doesn't work, nothing happens  
              onSearchRequested();  

          } else if (strText.equalsIgnoreCase(getResources().getString(R.string.menu_item_locator))) {
              startActivity(new Intent(MenuListActivity.this, StoreLocatorActivity.class));  
          }  
      }  

请帮忙，我怎么调用从我MenuActivity搜索请求？

Please help, how do I invoke the search request from my MenuActivity?

推荐答案

你检查你的RES / XML / searchable.xml？

did you check your res/xml/searchable.xml?

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
  android:hint="@string/search_hint" 
  android:label="@string/search_label">
</searchable>

搜索对话框不显示的时候你已经很难codeD字符串提示和标签。他们必须@string资源。

Search dialog doesn't show up when you have hard coded strings for hint and label. They have to be @string resources.

此外，没有必要打电话或在您的通话活动覆盖onSearchRequested（）方法，除非你想从像一个按钮或列表项的UI部件之一来使用搜索。

Also, there is no need to call or override the onSearchRequested() method in your calling activity unless you want to invoke search from one of your UI widgets like a Button or a ListItem.
