問題描述

如果您擁有 Android 手機，您無疑已經(jīng)注意到在某些應(yīng)用程序中，鍵盤布局如何從標準問題變?yōu)閮H數(shù)字或具有 .com 或 .net 基于文本字段輸入類型(例如電話號碼)的特殊按鈕.所以我有兩個問題:

1. 如何觸發(fā)此自定義?我懷疑它與 EditText 格式
有關(guān)
2. 如果我想添加一些自定義按鈕來注入特定模式，是否可以更進一步?假設(shè)我會有一個 AND 按鈕，按下該按鈕會將所有大寫的AND"添加到文本字段中，并用空格包圍.這可以做到嗎?
3. 我不要問的是如何在 onKeyPress 事件中捕獲一些組合鍵，然后用模式填充文本字段 - 我已經(jīng)知道如何做到這一點了.

它由 android:inputType XML 屬性(或 setInputType() 方法)控制.

有關(guān)可用選項的信息，請參閱 a>，但我不相信目前有任何方法可以完全自定義鍵盤，但我可能是錯的.

If you own Android phone you are no doubt have noticed how in the certain apps the keyboard layout can change from the standard issue to digits-only or to have .com or .net special buttons based on the text field input type (e.g. phone number). So I have 2 questions:

1. how to trigger this customization? I suspect it has to do with EditText format
2. Can this be taken even further if I want to add some custom buttons to inject a specific pattern? Say I would have an AND button which when pressed will add all uppercase " AND " surrounded by spaces to the text field. Can this be done?
3. What I'm not asking is how to capture some key combination in onKeyPress event and then populate text field with a pattern - I pretty much know how to do that already.

It is controlled by the android:inputType XML attribute (or the setInputType() method).

For info on the available options see the pages for the XML attribute or the object's method.

As an example, the following XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
    <EditText 
        android:text="example text"  
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:inputType="phone" />
</LinearLayout>

will give you this layout:

whereas changing the inputType to textEmailAddress will give you this:

You can customize the "action" button as explained here, but I don't believe there's any way to do full customization of keyboards at this time, but I could be wrong.
