Answer 1

To set password enabled in EditText, We will have to set an "inputType" attribute in xml file.If we are using only EditText then we will have set input type in EditText as given in below code.

                    <EditText
                    android:id="@+id/password_Edit"
                    android:focusable="true"
                    android:focusableInTouchMode="true"
                    android:hint="password"
                    android:imeOptions="actionNext"
                    android:inputType="textPassword"
                    android:maxLength="100"
                    android:nextFocusDown="@+id/next"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />

Password enable attribute is

 android:inputType="textPassword"

But if we are implementing Password EditText with Material Design (With Design support library) then we will have write code as given bellow.

<android.support.design.widget.TextInputLayout
                xmlns:app="http://schemas.android.com/apk/res-auto"
                android:id="@+id/txtInput_currentPassword"
                android:layout_width="match_parent"
                app:passwordToggleEnabled="false"
                android:layout_height="wrap_content">

                <EditText
                    android:id="@+id/password_Edit"
                    android:focusable="true"
                    android:focusableInTouchMode="true"
                    android:hint="@string/hint_currentpassword"
                    android:imeOptions="actionNext"
                    android:inputType="textPassword"
                    android:maxLength="100"
                    android:nextFocusDown="@+id/next"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />
            </android.support.design.widget.TextInputLayout>

@Note: - In Android SDK 24 and above, "passwordToggleEnabled" is by default true. So if we have the customs handling of show/hide feature in the password EditText then we will have to set it false in code as given above in .

app:passwordToggleEnabled="true"

To add above line, we will have to add below line in root layout.

xmlns:app="http://schemas.android.com/apk/res-auto"

Answer 2

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

This one works for me.
But you have to look at Octavian Damiean's comment, he's right.

Answer 3

The only way that worked for me using code (not XML) is this one:

etPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
etPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());

Answer 4

I found when doing this that in order to set the gravity to center, and still have your password hint show when using inputType, the android:gravity="Center" must be at the end of your XML line.

<EditText android:textColor="#000000" android:id="@+id/editText2" 
    android:layout_width="fill_parent" android:hint="Password" 
    android:background="@drawable/rounded_corner" 
    android:layout_height="fill_parent" 
    android:nextFocusDown="@+id/imageButton1" 
    android:nextFocusRight="@+id/imageButton1" 
    android:nextFocusLeft="@+id/editText1"
    android:nextFocusUp="@+id/editText1" 
    android:inputType="textVisiblePassword" 
    android:textColorHint="#999999" 
    android:textSize="16dp" 
    android:gravity="center">
</EditText>

Answer 5

Here's a new way of putting dots in password

<EditText
    android:id="@+id/loginPassword"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:inputType="textPassword"
    android:hint="@string/pwprompt" /

add android:inputType = "textPassword"

Answer 6

See this link text view android:password

This applies for EditText as well, as it is a known direct subclass of TextView.
