Question

我制作了一个用于弹出的xml布局文件。在布局中，我设置了两个CheckedTextViews。我可以在预览中看到文字。但是，当我在AVD和手机上安装并激活它时，看不到它的文本。这是非常简单的代码。但是我不知道这是怎么回事。

我将CheckedTextView替换为CheckBox。但这仍然行不通。

我检查了您的代码，您的代码很好。只需进行一些更改即可获得所需的输出。

您只需在第二个CheckedTextView中添加一行代码，即周末复选框。

android:checkMark="?android:attr/listChoiceIndicatorMultiple"

请尝试以下代码：
