Android - How to set numeric EditText to a specified number of digits

I want an EditText to contain exactly 8 digits (like bank accounts). Of course in addition to :

android:inputType="number"

Is there an option in XML or do I have to manage this programmatically ?

Try the following line in your EditText:

android:maxLength="8"

Programmatically.

Also, you can save time by using existing library EditText with validation. You can use a regex type with following pattern [0-9]{8}.

    android:id="@+id/etxtClientPhone"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_alignParentLeft="true"
    android:gravity="left"
    android:textColor="@color/hub_blue_normal"
    android:visibility="visible"
    android:selectAllOnFocus="true"
    android:digits="0123456789"

Change input type in decimal, then set maxLength="8".

android:inputType="decimal"
android:maxLength="8"

I think there is no way just in xml. You have to validate it programmatically.

@Override
public void afterTextChanged(Editable s) {
    // validation code goes here
}
