Textview:setinputtype (). Settransformationmethod ()

In some cases, it may be necessary to run a TextView (perhaps created at runtime or written in an XML file) in a seasonal operation. Since it is not possible to specify it as a password input property through an XML file, how does this work?

There are two methods of TextView:

Setinputtype (int) Settransformationmethod (Transformationmethod)

　　

Setinputtype can change the way TextView is entered: contact, Email, Date, time, short Message, Normal Text, Password, and so on. You can also specify a variety of correction options, such as capitalize the first letter of the word, capitalize the sentence, AutoCorrect, and so on.

How to use:

int InputType = Inputtype.type_class_text | Inputtype.type_text_flag_auto_correct                      | Inputtype.type_text_flag_multi_line | Inputtype.type_text_flag_auto_correct                      | Inputtype.type_text_variation_short_message;       Textview.setinputtype (inputtype);

Settransformationmethod, in turn, can support the conversion of input characters, including the elimination of line breaks, and conversion to masks. How to use:

Textview.settransformationmethod (Passwordtransformationmethod.getinstance ());

In general, if you need to implement your own conversion, you can achieve your goal by implementing the Transformationmethod interface (such as making all the characters you enter a, or entering a display z, input z display a, and so on).
