Android EditText 大写字母数字键盘

Question

I have an EditText and it should display alphanumeric keyboard (both letters and numbers visible on keyboard). Letters must be upper case. What attributes should I set for EditText? I tried:

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inputType="textVisiblePassword"
    android:textAllCaps="true" />

This shows lower case alphanumeric keyboard.

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inputType="textCapCharacters"
    android:textAllCaps="true" />

And this shows upper case keyboard but without numbers.

I need a keyboard like this:

Both numbers and upper case letters visible on default layout (without the need to switch CAPS on, or in other words with CAPS turned on in default).

Answer 1

try inputType = textVisiblePassword|textCapCharacters

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inputType="textVisiblePassword|textCapCharacters" />

Answer 2

When you have android:inputType="textCapCharacters" , you will have alphanumeric keyboard as you see in these pictures:

You can change keyboard style in settings of your phone. User can also set keyboard so that it is invisible at all. But you can make custom keyboard. This question may help you: How can you make a custom keyboard in Android?
