在扩展InputMethodService的类中运行function / void

Question

我有这个MainClass扩展了InputMethodService（缩短版本）：

public class PcAsKeyboard extends InputMethodService implements KeyboardView.OnKeyboardActionListener {

    private Keyboard mKeyboard;

    private KeyboardView mInputView;

    private InputMethodManager mInputMethodManager;

    @Override 
    public void onCreate() {
        super.onCreate();
        mInputMethodManager = (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);

        ServerThread chatServerThread = new ServerThread(this);     
        chatServerThread.start();        
    }

    public void output(CharSequence text) {
        getCurrentInputConnection().commitText(text, 1); // Sends CharSequence "text" to input field
    }
}

现在我想访问函数/ void＆＃34;输出＆＃34;来自另一个班级（缩短）：

public class ClientThread extends Thread {  

    // the socket where to listen/talk  
    Socket socket;

    InputStream inputStream;

    //InputMethodService ims = new InputMethodService();

    String message;

    BufferedReader bufferedReader;

    //private PcAsKeyboard main = null;    


    // Constructor
    ClientThread(Socket socket, PcAsKeyboard main) {

        this.socket = socket;

        // Creating stream for data input & a reader for the stream to get the message
        try
        {
            inputStream = socket.getInputStream();

            InputStreamReader isReader = new InputStreamReader(inputStream);

            bufferedReader = new BufferedReader(isReader);

        }

        catch (IOException e) {

            // Exception creating InputStream!

            return;

        }

    }   


    // Runs forever
    public void run() {

        while(true) {   
            // Trying to get a line from the input stream   
            try {
                message = bufferedReader.readLine();
            }   
            catch (IOException e) { 
                // "Exception reading InputStream!
                break;              
            }               
            // TODO: Write var message in input Field
            // main.output(message);            
            // ims.getCurrentInputConnection().commitText(message, 1); 
        }       

        try {
            inputStream = socket.getInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

}

At＆＃34; // TODO：在输入字段＆＃34;中写入var消息我想用变量＆＃34; message＆＃34;来运行输出函数。 我已经尝试在创建＆＃34; ClientThread＆＃34;时将主类（PcAsKeyboard）作为变量传递。类，但这没有工作/给空指针异常。当我尝试访问＆＃34; InputMethodService＆＃34;并调用＆＃34; .getCurrentInputConnection（）＆＃34;然后

我希望你们中的某个人可以帮助我解决这个问题^ - ^
