Programmatically change input type of the EditText from PASSWORD to NORMAL & vice versa

Question

Add an extra attribute to that EditText programmatically and you are done:

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

For numeric password (pin):

password.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_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 using 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

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) {
                        // hide password
                    mEtPwd.setTransformationMethod(PasswordTransformationMethod.getInstance());
                } else {
                        // show password
                    mEtPwd.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
                }
            }
        });

for full sample code refer http://www.codeproject.com/Tips/518641/Show-hide-password-in-a-edit-text-view-password-ty

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

Method above didn't really work for me. Answer below works for 2.2 sdk.

password.setTransformationMethod(PasswordTransformationMethod.getInstance());

Set inputType for an EditText?

Another simple example using ImageView to toggle visibility with less code, because of single InputType assign we need only equality operator:

EditText inputPassword = (EditText) findViewById(R.id.loginPassword);
ImageView inputPasswordShow = (ImageView) findViewById(R.id.imagePasswordShow);
inputPasswordShow.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View view) {
         if(inputPassword.getInputType() == InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD) {
              inputPassword.setInputType( InputType.TYPE_CLASS_TEXT |
                                        InputType.TYPE_TEXT_VARIATION_PASSWORD);
         }else {
              inputPassword.setInputType( InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD );
         }
         inputPassword.setSelection(inputPassword.getText().length());
    }
});

Replacing :

InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD

With :

InputType.TYPE_CLASS_TEXT

Will give the same result but shorter word.

Checkbox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                // checkbox status is checked.
                if (isChecked) {
                        //password is visible
 PasswordField.setTransformationMethod(HideReturnsTransformationMethod.getInstance());     
                } else {
                        //password gets hided
             passwordField.setTransformationMethod(PasswordTransformationMethod.getInstance());       
                }
            }
        });
