</blockquote>

Creating an input method is covered in <a href="http://developer.android.com/guide/topics/text/creating-input-method.html">the Android developer documentation</a>, which is on the Internet.

<blockquote>
 Do you guys have samplecode?
</blockquote>

There is a sample in the <code>samples/</code> directory of your SDK installation, if you downloaded sample code from the SDK Manager. Look for <code>SoftKeyboard</code>.

<blockquote>
 Do I need root to do this?
</blockquote>

No.

<blockquote>
 What's the structure behind it? (Is it just a regular Activity with a Service??)
</blockquote>

It is <a href="http://developer.android.com/reference/android/inputmethodservice/InputMethodService.html">an <code>InputMethodService</code></a>.

blocks|key|2833785|text|所以，当我在Swype上工作的时候，我做了大约两年。您不需要根目录，只需要实现一个InputMethodService即可。您可以从大多数文本框中获取文本，但不是所有文本框(并非所有编辑字段都正确地实现了各自的API)。特别是输入类型为INPUT_TYPE_NULL的任何东西都不能很好地工作)。要获取文本，您可以调用inputConnection.getExtractedText|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2833786|请注意-+API很糟糕，应用程序在使用它时时好时坏。一个基本的键盘很简单，但尝试做任何复杂的事情都会花费大量的时间。在大键盘上花费了大量的工时|2833787|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

So, I did this for about 2 years, when I worked on Swype. You don't need root, you just need to implement an InputMethodService. You can get the text out of most textboxes, but not all (not all edit fields correctly implement their half of the APIs. Particularly anything with an input type INPUT_TYPE_NULL will not work well). To get the text you would call inputConnection.getExtractedText

Be warned- the API is bad, and apps are hit and miss on working with it. A basic keyboard is easy, but try and do anything complex and you'll spend a lot of time. A lot of man hours went in to the big keyboards

No, root is not required to do this.

You need to use the <code>inputMethodService</code>, see the <a href="http://developer.android.com/reference/android/inputmethodservice/InputMethodService.html" rel="nofollow">documentation</a>.

root: no

yes it is possible.

String currentText = ic.getExtractedText(new ExtractedTextRequest(), 0).text;

I'd like to write an custom keyboard which should work on all devices that are running Android 4.0 and up. So first I searched the net but didn't found anything about that. So how can I create an app which replaces the stock keyboard of Android?

What I'd like to know:
