如何自动拨打数字键盘？

Question

I'm beginner in Java Android developing. I'm using Eclipse SDK 3.6.1 version. I'm trying to do this thing: when I start my application it calling to input a pin code, but if you want to input a number you have to click on the pin field. How to call number keyboard automatically? I'm using Samsung gt-i5500, it's touchscreen.

Answer 1

我实际上没有尝试过，但是您可以尝试在pin字段上设置android:inputType="phone" ，然后在代码中的该字段上调用requestFocus 。

Answer 2

You just have to set android:inputType="number" for your pin editText as below:

  <EditText   
android:layout_height="wrap_content"
android:layout_width="wrap_content" 
android:inputType="number" 
></EditText>

And a numeric keyboard will be shown when user clik on the field.

Answer 3

You can tell the UI (specifically the TextView:EditText) what type of field you are dealing with by setting the inputType. Here are a list of the available input types , and, depending on what you choose, you'll receive that keyboard when you enter data into the field.

In your case, you're most likely going to want inputType:number. See the link I provided for the entire list of available options.
