如何從JSON中添加表格中的行

由於我還在學習Android，我認爲我的問題對您來說很簡單。我試圖顯示一個包含來自mysql的信息令牌的表。例如，我想顯示客戶端命令的命令。如果他訂購了一種產品，我會有一排，所以我將擁有與他訂購的產品數量一樣多的行。我真的不知道該怎麼做，而且我也沒有在網上找到解決方案。（表格中的所有框都可以編輯）。如何從JSON中添加表格中的行

有幾個方法可以做到這一點。您可以使用ListView，如在this example.

我喜歡使用TableLayout。將TableLayout放入XML文件中，然後在代碼中動態添加行。 Here is an example如何做到這一點。

在我的情況下，適當的方法是使用表，因爲它可以編輯。有些框會有EditText類型，其他框會有一個微調框類型... – user2235164 2013-05-07 08:06:30
