安卓搜索與建議

Question

我想用建議進行搜索。運行該應用程序，並在我的下面日誌Log.d("states","a onCreate")，Log.d("states",arg0.toString())，Log.d("states",query)或Log.d("states","searchactivity onCreate")執行的搜索框中鍵入非字符串後

。

我該怎麼做才能做到這樣做在a.java中的query()方法或b.java中的onCreate()方法被調用？

請不要發送給我的谷歌開發人員文件，它非常混亂。

MainActivity.java

package com.example.searchapp; 


import android.app.ActionBar; 
import android.app.Activity; 

import android.app.SearchManager; 
import android.content.Context; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.Menu; 
import android.view.MenuInflater; 
import android.widget.SearchView; 

public class MainActivity extends Activity { 

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

     Log.d("states","MainActivity onCreate"); 

     ActionBar actionBar = getActionBar(); 
     //actionBar.setDisplayShowHomeEnabled(false); 
     actionBar.setDisplayShowTitleEnabled(false); 

    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the options menu from XML 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.options_menu, menu); 

     // Get the SearchView and set the searchable configuration 
     SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
     SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView(); 
     // Assumes current activity is the searchable activity 
     searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); 
     searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default 
     //searchView.setSubmitButtonEnabled(true); 
     searchView.setQueryRefinementEnabled(true); 

     return true; 
    } 

}

      String arg4) { 
     // TODO Auto-generated method stub 
     Log.d("states",arg0.toString()); 
     String query = arg0.getLastPathSegment().toLowerCase(); 
     Log.d("states",query); 
     return null; 
    } 

    @Override 
    public int update(Uri arg0, ContentValues arg1, String arg2, String[] arg3) { 
     // TODO Auto-generated method stub 
     return 0; 
    } 

}

public class b extends Activity { 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     Log.d("states","searchactivity onCreate"); 
     Intent intent = getIntent(); 
     if (Intent.ACTION_SEARCH.equals(intent.getAction())) { 
      String query = intent.getStringExtra(SearchManager.QUERY); 

      Log.d("states",query); 

     } 
    } 

}

我想在你的一類，你必須實現的getType（） - 方法：

private UriMatcher uriMatcher; 

@Override 
public boolean onCreate() { 
    final String authority = "com.example.searchapp.searchsuggestion"; 
    uriMatcher = new UriMatcher(UriMatcher.NO_MATCH); 
    uriMatcher.addURI(authority, SearchManager.SUGGEST_URI_PATH_QUERY, SEARCH_SUGGEST); 
    uriMatcher.addURI(authority, SearchManager.SUGGEST_URI_PATH_QUERY + "/*", SEARCH_SUGGEST); 
    return true; 
} 

@Override 
public String getType(Uri uri) { 
    switch (uriMatcher.match(uri)) { 
     case SEARCH_SUGGEST: 
      return SearchManager.SUGGEST_MIME_TYPE; 
     default: 
      throw new IllegalArgumentException("Unknown URL " + uri); 
    } 
}
