我試圖從支持庫中合併GridLayout，但它不工作。我的目標是打造爲API版本10.我使用XML代碼如下所示：Eclipse提供的android.support.v7.widget.GridLayout錯誤未能實例化
<?xml version="1.0" encoding="UTF-8"?>
<android.support.v7.widget.GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:grid="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android.support.v7.widget.columnCount="6" >
<Button
android:id="@+id/button1"
android.support.v7.widget.layout_column="1"
android.support.v7.widget.layout_columnSpan="2"
android.support.v7.widget.layout_gravity="left"
android.support.v7.widget.layout_row="1"
android:text="Button" />
</android.support.v7.widget.GridLayout>
當Eclipse嘗試編譯此，給出的錯誤是：android.support.v7.widget.GridLayout失敗實例。棧跟蹤是：

基於沒有人面臨這個問題的事實，我懷疑我沒有正確設置v7庫。步驟我都遵循：
- 在「網格佈局」目錄
- 添加了此項目到我的主要項目
- 添加了來自GridLayout的lib目錄罐子我的主要的lib目錄下創建一個庫項目項目
任何幫助將不勝感激。
感謝您的努力幫助球員，但沒有任何工作。但是，終於找到了解決辦法。極其尷尬地說，我需要更新我的機器上的JAVA。道歉... – Aviral
我有完全相同的問題，關閉，因爲對我來說沒有意義。 –
:-)希望升級Java的解決方案也能爲您工作...... – Aviral
