Question

我正在尝试在setError()上使用EditText方法，但每次崩溃时都会使用此日志：

我通常在片段中调用setError，如下所示：

mEditText.setError("test")

有人能帮助我吗？

Answer 1

我正在使用MaterialEditText的库来重现KitKat中Lollipop的浮动标签属性..因为几个月前AppCompat仍然没有让这个工作..这个问题发生在我试图MaterialEditText上的setError。我将AppCompat更新到最新版本+ TextInputLayout + Android的EditText，我得到了一切正常工作：setKat和Lollipop中的setError方法和浮动标签。

EditText的setError（）崩溃了
