如何在android中的按鈕中獲取動態佈局/字段

在我的android項目中，我在activity_investments.xml中使用了三個edittext和四個按鈕。在activity_investments如果我按下添加字段按鈕，整個佈局我的意思是三個edittext與四個按鈕應該再次顯示以前的佈局..我不知道該怎麼做。如何在android中的按鈕中獲取動態佈局/字段

請幫我弄這個..

下面是我code..any幫助將不勝感激...在此先感謝..

它只是谷歌，很多教程可供選擇。 [可能的重複。]（http://stackoverflow.com/questions/6216547/android-dynamically-add-views-into-view） –

在許多教程中只顯示一個字段..但在這裏我的情況下，我想整個佈局應該顯示一個按鈕後點擊 –

，您可以創建並添加像下面
