在我的應用程序中，我從MySQL數據庫中獲取訂單詳細信息，並基於db中的行數動態地在應用中的LinearLayout中添加TextView（如果存在有6行，然後6個文本視圖將顯示在應用程序） 在做工具欄從Activity禁用，由於這個我不能回到我的父活動 我不知道，但我想用setLayoutParams是這裏的罪魁禍首。在線性佈局中動態添加文本視圖中獲取工具條
請幫忙！

你能回到以前的屏幕，如果你沒有叫你'的getData（）'？ – SripadRaj
的getData（）是好的。是的，我能夠回去即工具欄是可見的，直到的getData（） –
爲什麼你使用'LinearLayout'，而不是直接的'ListView'或'RecyclerView'？看起來你正在阻止'getData（）'的UI線程。將加載數據從DB移動到'AsyncTask'。 – j2ko
