widget.SearchView在Android中未显示用于语音搜索的MIC按钮 [英] widget.SearchView not showing MIC button for voice search in android

问题描述

我在名为activity_products_final的布局文件中有一个seachview

I have a seachview in layout file named activity_products_final

    <android.support.v7.widget.SearchView
        android:id="@+id/searchView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:queryHint="Search..">
    </android.support.v7.widget.SearchView>

</LinearLayout>

活动:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_products_final);



    searchView = (android.support.v7.widget.SearchView) findViewById(R.id.searchView);
    searchView.setIconified(false);
    searchView.onActionViewExpanded();
    searchView.clearFocus();
    searchView.setOnQueryTextListener(new android.support.v7.widget.SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            if (adapter != null)
                filterData(query);
            return false;
        }

        @Override
        public boolean onQueryTextChange(String query) {
            if (adapter != null)
                filterData(query);
            return false;
        }
    });



    ImageView closeButton = (ImageView) searchView.findViewById(R.id.search_close_btn);
    closeButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            searchView.setQuery("", false);
            searchView.clearFocus();
            //collapseAll();
        }
    });
}

清单文件

<activity

    android:name=".ActivityProductList"
    android:configChanges="orientation|screenSize"
    android:label="@string/title_activity_products"
    android:launchMode="singleTop"
    android:parentActivityName=".ActivityStartShopping"
    android:screenOrientation="portrait"
    >
    <intent-filter>
        <action android:name="android.intent.action.SEARCH" />
    </intent-filter>

    <meta-data
        android:name="android.app.searchable"
        android:resource="@xml/searchable" />

</activity>

xml/searchable

xml/searchable

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

根据Google文档，我必须使用android:voiceSearchMode ="showVoiceSearchButton | launchRecognizer"来显示MIC按钮.

As per google docs i have to use android:voiceSearchMode="showVoiceSearchButton|launchRecognizer" to show MIC button.

我关注了该文档，但没有显示MIC按钮来捕获语音输入.

I followed the doc but it is not showing MIC button to capture voice input.

有人可以帮我吗?

推荐答案

您需要创建 SearchableConfiguration .将其添加为xml资源文件夹中的 searchable.xml :

You need to create a SearchableConfiguration. Add this as searchable.xml in your xml resource folder:

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
  android:hint="search..."
  android:label="@string/app_name"
  <!-- the next line enables the voice button display -->  
  android:voiceSearchMode="showVoiceSearchButton|launchRecognizer"/>
