如何將彈出框中的文本設置爲android中的特定文本視圖？

Question

我在我的應用程序中創建了兩個動態按鈕和一個動態文本。現在我想要更改TextView中的文本，當我點擊按鈕（編輯）。當我點擊編輯按鈕時，彈出框會來和在該框我會插入一些文本，並且該文本應該放置到適當的TextView。我怎樣才能做到這一點？我粘貼了我的代碼。

公共類CreateButton延伸的ActivityGroup實現View.OnClickListener { INT I = 0，delet_id = 0，tr_id = 0，edit_id = 0，無= 1，TV_ID = 0，TG = 1; TableLayout tl_bed，tl_kitchen，tl_living，tl_dining; TableRow tr; 按鈕btn_delete，編輯; TextView [] tv;
