Java startSearch不启动搜索活动

Java startSearch不启动搜索活动,java,android,xml,searchview,searchactivity,Java,Android,Xml,Searchview,Searchactivity,我在活动中添加了一个SearchView,并定义了一个搜索活动来处理搜索。我添加了OnQueryTextListener,并从onQueryTextSubmit()方法调用了startSearch()方法。当我将全局搜索设置为true时,它会启动谷歌搜索。当我将其设置为false时,什么也没有发生。代码如下: final SearchView searchText = (SearchView) customView.findViewById(R.id.txtSearch); searc

我在活动中添加了一个SearchView,并定义了一个搜索活动来处理搜索。我添加了OnQueryTextListener,并从
onQueryTextSubmit()
方法调用了
startSearch()
方法。当我将全局搜索设置为
true
时,它会启动谷歌搜索。当我将其设置为
false
时,什么也没有发生。代码如下:

final SearchView searchText = (SearchView) customView.findViewById(R.id.txtSearch);
     searchText.setFocusable(true);
     searchText.setIconifiedByDefault(false);
     searchText.setQueryHint(SearchActivity.this.getResources().getString(R.string.search_text_hint));
     final SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
         @Override
         public boolean onQueryTextChange(String newText) {
             // Do something
             final String searchText = newText;
             if (newText.equals("")) {
                 suggestAdapter.removeAll();
                 suggestAdapter.notifyDataSetChanged();
                 return true;
             }
             if (newText.length() < 4) {
                 return true;
             }
             if (!last_onTextChanged.equals(newText))
                 onchangeHandler.removeCallbacksAndMessages(null);
             else
                 return true;
             last_onTextChanged = newText;
             onchangeHandler.postDelayed(new Runnable() {
                 @Override
                 public void run() {
                     getSearchSuggestions(searchText);
                 }
             },800);
             return true;
         }

         @Override

             startSearch(query,true,null,false);

以下内容在自定义操作栏布局自定义搜索\u操作\u Bar.xml中定义

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

            android:layout_centerVertical="true"
            android:id="@+id/ic_barcode_button"/>
    </LinearLayout>
</RelativeLayout>

以下内容在res/xml/searchable.xml中定义

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/abc_icon"

        android:layout_centerVertical="true"
        android:visibility="gone"
        android:id="@+id/ic_abc_button"/>
        <ImageButton
            android:layout_width="wrap_content"

            android:layout_centerVertical="true"

    <provider android:name="com.rayat.pricewiz.provider.SearchContentProvider"
        android:authorities="com.rayat.pricewiz.provider.SearchContentProvider" />

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/abc_icon"

        android:id="@+id/ic_abc_button"/>
        <ImageButton

非常感谢您提供的任何帮助

您是否已将此用于主要活动的信息放入Manifest.xml中

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/abc_icon"
        android:layout_toEndOf="@+id/txtSearch"
        android:layout_marginEnd="20dp"
        android:layout_marginTop="12dp"
        android:layout_marginStart="0dp"
        android:background="@color/logo_green"
        android:layout_centerVertical="true"
        android:visibility="gone"

你找到答案了吗?没有,我最终添加了自己的实现,手动添加操作栏中的编辑文本和按钮,并处理搜索查询。重写活动的
handleIntent
方法,以防止搜索结果活动打开其自身的另一个活动实例是的,在这里也是一样,我也这样做了。
