如何清除ListViewItem上的按下效果？

Question

我有一個ListView，當我用鼠標選擇一行時，當我按下時，該行得到一些填充或邊距，我不知道它是什麼，我只是希望它不會發生，只需選擇一行而無需任何效果，例如當我用鍵盤選擇一行時。

要更改默認行爲，您必須更改ListViewItem的樣式。你可以找到關於msdn或本地驅動器上這些樣式：

C：\ Program Files文件（x86）的\的Windows套件\ 10 \設計時\ CommonConfiguration \中性\ UAP \ 10.0.14393.0 \通用\ generic.xaml

問題的視覺狀態很可能是Pressed和PressedSelected。將這些視覺狀態改變爲任何你想要的ListView。
