Android GridView與不同大小的列

Question

這是我的第一個問題。 我正在開發一個Android應用程序，我使用GridView作爲DataGrid。 我有一些網格有7或8列，我需要根據其內容使gridview的列具有不同的寬度。 我檢查所有帖子，但找不到解決方案。 我現在正在做的是設置每個視圖的LayoutParams，計算一個固定寬度，併爲每個視圖選擇一個百分比，視圖獲得正確的寬度，但第二個視圖的文本顯示在第一個視圖上等等。 我所有的視圖都是TextView或EditText。

我會爲您提供任何幫助。 非常感謝您提前！

首先告訴我，你如何設置你的GridView？你使用setAdapter方法嗎？ 如果你告訴我，我可以幫你，而且我認爲你必須爲此創建CustomAdapter。因此，第一步回答我的問題。
