Can I use numberPassword input type and still see the input?

Can I use numberPassword as input type and still see the input?
My goal is to have a 0-9 keyboard with as few as possible other keys (that's why I prefered numberPassword over phone), but the user should still be able to see what he just typed.
This is what I have, but right now the passwords are hidden behind asterisks.
android:digits="1234567890"
android:inputType="numberPassword"
Note: I also tried setInputType(InputType.TYPE_NUMBER_VARIATION_PASSWORD), which made the input visible, but changed the keyboard from numbers-only to a regular keyboard. I need they keyboard to display numbers-only though.

In Java, just do this:
edittext.setTransformationMethod(PasswordTransformationMethod.getInstance());
If you wanted to hide the password later on, you would just do this:
editText.setTransformationMethod(HideReturnsTransformationMethod.getInstance());

This did the job:
uEditText = (EditText) findViewById(R.id.editText);
uEditText.setTransformationMethod(null);

There are different ways you can solve this problem
You can use use TextInputEditText with TextInputLayout like below
<android.support.design.widget.TextInputLayout
android:id="#+id/etPasswordLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:passwordToggleEnabled="true"
android:layout_marginBottom="#dimen/login_spacing_bottom">
<android.support.design.widget.TextInputEditText
android:id="#+id/etPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/fragment_login_password_hint"
android:inputType="textPassword"/>
</android.support.design.widget.TextInputLayout>
With passwordToggleEnabled, you can toggle between asterisk and password values
You can use the Transformation class to toggle password asterisk and value like below
edittextObject.setTransformationMethod(PasswordTransformationMethod.getInstance());
You can create a custom keyboard with the values you want to display in your keyboard. You can see how to achieve this in this tutorial I wrote about custom keyboard

How to make Android EditText expand vertically when full

I have this EditText
<EditText
android:layout_width="match_parent"
android:layout_height="72dp"
android:hint="#string/write_message"
android:textColorHint="#color/primary_color"
android:ems="10"
android:imeOptions="actionDone"
android:inputType="textImeMultiLine"
android:id="#+id/message_input"
android:layout_gravity="center_horizontal"
android:backgroundTint="#color/primary_color"/>
When the box is filled up with user inputted text, it scrolls to the right to make room for more text, I do not like this behavior, and would prefer it if the EditText box expanded upwards when it needs more room? Is there a way to do this? Thanks.

Yes, this actually involves two things:
Making the EditText accept multi-line input.
Having its height grow as more text lines are added.
Therefore, to achieve this, you need to set up:
android:inputType="textMultiLine"
android:layout_height="wrap_content"
(Be mindful of the difference between textMultiLine and textImeMultiLine).
The full XML snippet would be:
<EditText
android:layout_width="match_parent"
android:inputType="textMultiLine"
android:layout_height="wrap_content"
android:hint="#string/write_message"
android:textColorHint="#color/primary_color"
android:ems="10"
android:imeOptions="actionDone"
android:id="#+id/message_input"
android:layout_gravity="center_horizontal"
android:backgroundTint="#color/primary_color"/>

Use both flags: textMultiLine will wrap your input, and textImeMultiLine will provide a break-line key in your keyboard.
<EditText
...
android:layout_height="wrap_content"
android:inputType="textImeMultiLine|textMultiLine"
... />

In my case I have multiline text, but it showed one line and a keyboard:
Though I have already set android:inputType="textCapSentences|textAutoCorrect|textMultiLine", it didn't help. Then I understood that when the keyboard appears in DialogFragment, it collapses the EditText. See DialogFragment and force to show keyboard to show keyboard when DialogFragment shows.
Then I added a short delay (100-300 ms) before showing the keyboard. Now I have:
In AndroidManifest I set android:windowSoftInputMode="adjustResize" for current activity.

How to disable letters in keyboard (leave only digits)?

I'm developing Android application, and I need to disable letters for user's keyboard in order to allow user to input only digits in EditText. Please, tell me, is it possible?

add android:inputType="number" to the EditText in the layout xml.
More information on inputType's can be found at http://developer.android.com/reference/android/widget/TextView.html#attr_android:inputType
You can also go further and do something like:
<EditText
android:inputType="number"
android:digits="0123456789"
/>

EditText input = new EditText(this);
input.setInputType(InputType.TYPE_CLASS_NUMBER);
OR
Using XML
android:inputType="number"
