android需要在列表視圖中使用ratingbar的例子

我正在學習android，希望有一個示例代碼或使用ratingbar的例子只是爲了在listview中顯示評級和沒有onclick事件。android需要在列表視圖中使用ratingbar的例子

我正在使用json從mysql數據庫中獲取數據。轉換爲浮點數後的相同數據必須顯示在列表中的額定條中。我在這裏嘗試了很多例子，但大部分都不完整。

謝謝

以下是其中M使用在列表中顯示的字符串值

感謝。更新了我正在嘗試的代碼，如上所述。 –

感謝您的支持。得到它解決..使用ViewBinder類 –

你試試這個教程？

我希望這將有助於：？你嘗試過什麼]

謝謝。使用Viewbinder進行整理。但無論如何，該教程也在某些情況下有所幫助。 –

嘗試以下代碼

<RatingBar 
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent" 
    android:isIndicator="true" 
    android:numStars="5" 
    android:stepSize="1" 
    android:rating="5" 
    android:id="@+id/pop_ratingbar" 
    style="?android:attr/ratingBarStyleSmall" 
/> 

RatingBar ratingBar = (RatingBar) findviewbyid(R.id.pop_ratingbar); 
ratingBar.setRating(4.0f);

仍，如果你正面臨着比問題更喜歡下面project
