Android：水平翻轉佈局

Question

說我的佈局有一個按鈕與左邊對齊，並且TextView與右邊對齊。

我希望對於某些語言，佈局將按原樣顯示，但對於其他語言，按鈕應位於右側，而文本應位於左側。

是否有一些內置或簡單的方法來動態翻轉佈局視圖？

我可以創建一個differenet佈局並動態設置內容視圖，但如果有更好的建議，我寧願避免使用此解決方案。

感謝

在這裏，在我的示例代碼，我改變的按鈕佈局點擊你可以把你需要同樣

if laguage = "bl bla" call layout1(); 
else call layout2(); 

我不是創建不同的佈局，根據登錄進來，而是相同的佈局我正在動態分配不同的佈局屬性。
