我有一個設計爲xml的標題行表。現在我想在表中添加數據（我從json數組中獲取數據）。 我需要垂直滾動數據行而不影響標題行，所以我在標題行表格下方創建了另一個表格佈局。然後，對於每個新行的每個字段，我在java文件中設置佈局參數，然後將該行添加到第二個表格佈局。 但是，當數據被打印到日誌中時，沒有行可見。我無法弄清楚我的錯誤在哪裏。在tablelayout中動態添加的行是不可見的

你嘗試無效（）或postInvalid吃完（）後？ – goodm
不，我ddnot嘗試任何這些功能 – HimanshuR
一切嘗試使用requestLayout（）和invalidate（）後，我不記得哪一個是正確的。 – goodm
