试图从Android浏览器

Question

得到的搜索结果我想从Android浏览器中得到我的搜索值与下面的代码：

public void getBrowserHist() { 
     String[] mColumnStrings = 
         { Browser.SearchColumns._ID, 
           Browser.SearchColumns.SEARCH, 
           Browser.SearchColumns.DATE 
         }; 

       Cursor mCur = getContentResolver().query(Browser.SEARCHES_URI, 
         mColumnStrings, Browser.SearchColumns.SEARCH, null, null); 
     int url = mCur.getColumnIndex(Browser.SearchColumns.SEARCH); 
     Log.d(DEBUG_TAG, "Bookmarks count: " + mCur.getCount()); 
     mCur.moveToFirst(); 

      while (!mCur.isAfterLast()) { 
       Log.v("titleIdx", mCur.getString(url)); 

       mCur.moveToNext(); 

     } 
    } 

的问题是，搜索结果为空。 mcur.getCount（）方法返回0，我现在不是为什么。有没有人有任何建议？

Cursor cursor = this.context.getContentResolver().query(Browser.SEARCHES_URI, null, null, null, null); 
    if (cursor.moveToFirst()) { 
     while (!cursor.isAfterLast()) { 
      final int indexDate = cursor.getColumnIndex(Browser.SearchColumns.DATE); 
      final int indexTerm = cursor.getColumnIndex(Browser.SearchColumns.SEARCH); 
      String date = cursor.getString(indexDate); 
      String term = cursor.getString(indexTerm); 
      cursor.moveToNext(); 
     } 
    } 
    cursor.close();
