尝试检查 Creating an Input Method docs，因为它讨论了输入法编辑器 (IME)，它是一个允许用户输入文本的用户控件。

If you haven't worked with IMEs before, you should read the introductory article Onscreen Input Methods first. Also, the SoftKeyboard sample app included in the SDK contains sample code that you can modify to start building your own IME.

Designing the Input Method UI

There are two main visual elements for an IME: the input view and the candidates view. You only have to implement the elements that are relevant to the input method you're designing.

Input view

The input view is the UI where the user inputs text in the form of keyclicks, handwriting or gestures. When the IME is displayed for the first time, the system calls the onCreateInputView() callback. In your implementation of this method, you create the layout you want to display in the IME window and return the layout to the system. This snippet is an example of implementing the onCreateInputView() method:

  @Override
    public View onCreateInputView() {
        MyKeyboardView inputView =
            (MyKeyboardView) getLayoutInflater().inflate( R.layout.input, null);

        inputView.setOnKeyboardActionListener(this);
inputView.setKeyboard(mLatinKeyboard);

        return mInputView;
    }

In this example, MyKeyboardView is an instance of a custom implementation of KeyboardView that renders a Keyboard. If you’re building a traditional QWERTY keyboard, see the KeyboardView class.
