键盘拼写检查器

标签: java android

我刚刚在Android Studio中创建了一个简单的键盘应用程序,现在我想添加一些功能,例如拼写检查器。 我已经在这里找到了如何编写拼写检查器的解决方案:“ https://github.com/WillSen/spellchecker-autocorrect/blob/master/index.js” 但是现在,由于这是我的第一个Android-Studio项目,因此在将其应用于我的项目时遇到了一些问题: 如何读出用户按下的键? 如何将带有文字的数据库连接到Android Studio并使其离线可用? 如何在键上的XML文件中显示建议的单词? 我当前的主要功能如下:


import android.app.Service;
import android.content.Intent;
import android.inputmethodservice.InputMethodService;
import android.inputmethodservice.Keyboard;
import android.inputmethodservice.KeyboardView;
import android.media.AudioManager;
import android.os.IBinder;
import android.view.KeyEvent;
import android.view.View;
import android.view.inputmethod.InputConnection;

public class OrthKeyboard extends InputMethodService implements KeyboardView.OnKeyboardActionListener {

    private KeyboardView kv;
    private Keyboard keyboard;

    private  boolean isCaps = false;


    //Press Ctrl+O


    @Override
    public View onCreateInputView() {
        kv = (KeyboardView)getLayoutInflater().inflate(R.layout.keyboard,null);
        keyboard = new Keyboard(this,R.xml.qwerty);
        kv.setKeyboard(keyboard);
        kv.setOnKeyboardActionListener(this);
        return kv;
    }

    @Override
    public void onPress(int i) {

    }

    @Override
    public void onRelease(int i) {

    }

    @Override
    public void onKey(int i, int[] ints) {

        InputConnection ic = getCurrentInputConnection();
        playClick(i);
        switch (i)
        {
            case Keyboard.KEYCODE_DELETE:
                ic.deleteSurroundingText(1,0);
            break;
            case Keyboard.KEYCODE_SHIFT:
                isCaps = !isCaps;
                keyboard.setShifted(isCaps);
                kv.invalidateAllKeys();
                break;
            case Keyboard.KEYCODE_DONE:
                ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_ENTER));
                break;
                default:
                    char code = (char)i;
                    if(Character.isLetter(code) && isCaps)
                        code = Character.toUpperCase(code);
                    ic.commitText(String.valueOf(code),1);
        }

    }

    private void playClick(int i) {

        AudioManager am = (AudioManager)getSystemService(AUDIO_SERVICE);
        switch(i)
        {
            case 32:
                am.playSoundEffect(AudioManager.FX_KEYPRESS_SPACEBAR);
                break;
            case Keyboard.KEYCODE_DONE:
            case 10:
                am.playSoundEffect(AudioManager.FX_KEYPRESS_RETURN);
                break;
            case Keyboard.KEYCODE_DELETE:
                am.playSoundEffect(AudioManager.FX_KEYPRESS_DELETE);
                break;
            default: am.playSoundEffect(AudioManager.FX_KEYPRESS_STANDARD);
        }
    }

    @Override
    public void onText(CharSequence charSequence) {

    }

    @Override
    public void swipeLeft() {

    }

    @Override
    public void swipeRight() {

    }

    @Override
    public void swipeDown() {

    }

    @Override
    public void swipeUp() {

    }
}

我的XML这样:
