android开发过程中突然发现的warning
EditText 报出 “This text field does not specify an inputType or a hint”

//文本类型,多为大写、小写和数字符号。
    android:inputType="none"
    android:inputType="text"
    android:inputType="textCapCharacters"
    android:inputType="textCapWords"
    android:inputType="textCapSentences"
    android:inputType="textAutoCorrect"
