Question

我尝试在操作栏中使用搜索视图，但在我点击键盘底部的搜索按钮后，没有任何反应。我在下面发布我的代码。请忽略文件中的包名称。在我的代码中，我将searchview的值设置为textView，但未设置。 Log cat也没有显示任何其他内容。先感谢您。

    Folder.java ------------------------------------



    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.home, menu); 
    //----THIS ONE -----------
    // Associate searchable configuration with the SearchView
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.action_search)
    .getActionView();
    searchView.setSearchableInfo(searchManager
    .getSearchableInfo(getComponentName()));

    //----THIS ONE ---------------------------------------------------------------------------  
    // return true;
    return super.onCreateOptionsMenu(menu);
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

    String filter_id = null,Tickets_title = null;
    int start_limit=0,page_no=1;

    // TODO Auto-generated method stub
    switch (item.getItemId())
    { 
    case R.id.action_search:
    //Intent searchmenu = new Intent(Folders.this,SearchResultsActivity.class);

    //startActivity(searchmenu);
    return true;  

    default:
    return super.onOptionsItemSelected(item);
    }
    }   


    ------- SearchResultactivity --------------------

    package com.abc;
    import android.app.ActionBar;
    import android.app.Activity;
    import android.app.SearchManager;
    import android.content.Intent;
    import android.os.Bundle;
    import android.util.Log;
    import android.widget.TextView;

    public class SearchResultsActivity extends Activity {

    private TextView txtQuery;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_search_results);

    // get the action bar
    ActionBar actionBar = getActionBar();
    // Enabling Back navigation on Action Bar icon


    actionBar.setDisplayHomeAsUpEnabled(true);
    txtQuery = (TextView) findViewById(R.id.txtQuery);

    handleIntent(getIntent());
    }

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

    /**
    * Handling intent data
    */
    private void handleIntent(Intent intent) {
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
    String query = intent.getStringExtra(SearchManager.QUERY);



    /**
    * Use this query to display search results like 
    * 1. Getting the data from SQLite and showing in listview 
    * 2. Making webrequest and displaying the data 
    * For now we just display the query only
    */
    txtQuery.setText("Search Query: " + query);



    }

    }
    }

    ---------------- Activity_search_results.xml ------------------------
    <?xml version="1.0" encoding="utf-8"?>

你好答案是，

只需在特定活动下的清单文件中添加以下行。您想在其中显示搜索视图。

Answer 1

嗨Rajesh这是menu.xml文件

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
android:panelFullBackground="#ffff"  >
<!-- THIS ONE FOR SEARCH ITEMS -->
<item android:id="@+id/action_search"
android:icon="@drawable/ic_action_search"
android:title="@string/action_search"
android:showAsAction="ifRoom"
android:actionViewClass="android.widget.SearchView"/>

<!-- THIS ONE FOR GLOBAL SEARCH ITEMS -->

</menu>

大家好，问题解决了......我刚刚加了此代码在特定活动中，我为Search Functionaliy编写代码。

操作栏中的Searchview不起作用
