Programmatically change input type of the EditText

Question

In my application, I have an EditText whose default input type is set to android:inputType="textPassword" by deault. It has a CheckBox to its right, which is when checked, changes the input type of that EditText to NORMAL PLAIN TEXT. Code for that is

password.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

My problem is, when that CheckBox is unchecked it should again set the input type to PASSWORD. I've done it using-

password.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);

But, the text inside that edittext is still visible. And for surprise, when I change the orienatation, it automatically sets the input type to PASSWORD and the text inside is bulleted (shown like a password).

Any way to achieve this?

Answer 1

I change the input type on my checkbox, so on my OnCheckedChangeListener i do:

passwordEdit.setInputType(InputType.TYPE_CLASS_TEXT| (isChecked? InputType.TYPE_TEXT_VARIATION_PASSWORD|~InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD : InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD));

And it finally worked.

Seems like a boolean problem with TYPE_TEXT_VARIATION_VISIBLE_PASSWORD. Invert the flag and it should fix the problem.

In your case:

password.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD|~InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

Blockquote

final int[] count = {0};

    showandhide.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if(count[0] ==0)
            {
                password.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
                count[0]++;
            }
            else {

                password.setInputType(InputType.TYPE_CLASS_TEXT |
                        InputType.TYPE_TEXT_VARIATION_PASSWORD);
                showandhide.setText("Hide");
                count[0]--;
            }

        }
    });

Just for the people who are having same problem. Just add an extra attribute to that EditText programmatically and you are done.

password.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);

Also, make sure that the cursor is at the end of the text in the EditText. Because, when you change the input type, the cursor will be automatically set to the starting point. So I suggest to use the following code:

et_password.setInputType(InputType.TYPE_CLASS_TEXT | 
    InputType.TYPE_TEXT_VARIATION_PASSWORD);
et_password.setSelection(et_password.getText().length());

When using Data Binding, you can make use of the following code

<data>
        <import type="android.text.InputType"/>
.
.
.
<EditText
android:inputType='@{someViewModel.isMasked ? 
(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD) :
InputType.TYPE_CLASS_TEXT }'

If using Kotlin,

password.inputType = InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD

Answer 4

some dynamic situation holder.edit_pin.setInputType(InputType.TYPE_CLASS_NUMBER); will not work so better use both like that

holder.edit_pin.setInputType(InputType.TYPE_CLASS_NUMBER);
holder.edit_pin.setTransformationMethod(PasswordTransformationMethod.getInstance());

Note : this is suitable for when you are using dynamic controls like using arrayaapter

Answer 5

use this code to change password to text and vice versa

mCbShowPwd.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                // checkbox status is changed from uncheck to checked.
                if (!isChecked) {
                        // show password
                    mEtPwd.setTransformationMethod(PasswordTransformationMethod.getInstance());
                } else {
                        // hide password
                    mEtPwd.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
                }
            }
        });

This worked for me:

mytext.setInputType(InputType.TYPE_CLASS_NUMBER);
