Android numeric password field

Question

I have an EditText field which needs to be a numeric password field. Everything works OK in portrait mode; not in landscape. When the user selects the EditText field, the UI zooms into the field and when I type all the characters are visible.

I need a numeric keyboard also. I tried setting the input type to text password|number. If I remove "number" option everything works right; otherwise no.

Any suggestions?

This problem can be solved without using deprecated android:password. Use the following code snippet, but do not reverse the sequence of calls:

    EditText editText = (EditText) findViewById(R.id.MyEditText);
    editText.setInputType(InputType.TYPE_CLASS_NUMBER);
    editText.setTransformationMethod(PasswordTransformationMethod.getInstance());

Sure, but somehow not as clear as a simple android:password="true". I wonder why they deprecated it. – ettore Mar 08 '11 at 02:58

Somehow this does not seem to work on 2.3.x . Turning to landscape the passwort is still visible as described by Mar. – Marcus Wolschon Aug 29 '11 at 09:45
I just found out that `editText.setSingleLine(true);` after the `editText.setTransformationMethod()` causes the dots to stop being shown !! – Someone Somewhere Jan 05 '12 at 21:52

The simplest solution that I found for a numeric text entry that needed to be hidden (password style) was to use: android:inputType="numberPassword"

Full example that worked for me:

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    style="@style/MyLargeTextBox"
    android:background="@android:drawable/editbox_background_normal"
    android:id="@+id/txtWebServicePIN"
    android:layout_row="3"
    android:layout_column="2"
    android:layout_columnSpan="2"
    android:minWidth="100dp"
    android:maxWidth="100dp"
    android:inputType="numberPassword"
    android:maxLength="6"/>

`numberKeyboard` does not popup the 'only digits' softkeyboard. — Srujan Barai, Mar 14 '16 at 12:21

To fix the issue where the password is visible in the landscape mode full-screen editor (as Marcus described), you can add the following line to disable the full-screen editor:

editText.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI);

You may also want to change the typeface to monospace to better emulate the text-password behavior:

editText.setTypeface(Typeface.MONOSPACE);

Though this doesn't look nice on small devics, it's definitely a way to get the password hidden. – Trinimon Mar 14 '13 at 15:31

Using the deprecated

android:password="true"

may solve your problem.

Try this in XML & nothing changes in manifest file,

<EditText
         android:id="@+id/etPassword"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:inputType="textPassword"
         android:singleLine="true" />

Try with this:

EditText input = (EditText) findViewById(R.id.input);
input.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

I think you should use android:password="true" and android:numeric="integer". But as the Android documentation states (in R.attr.html, not in the TextView docs), these are deprectated and you should use android:inputType. inputType takes flag, so you can mix mulitple possibilities. And I think android:inputType="number | password" should work for you.

You should specify android:password="true" if you want to support older devices too.

See dtmilano's answer, plus the link I gave to a previous question which covers these points. Unfortunately passing both into `inputType` doesn't work. – Christopher Orr Mar 19 '10 at 11:21
