如何更改按下时的自定义键盘颜色...！

Question

嘿，我创建了一个游戏，所以我用edit-tex创建了自定义键盘（numPad）我可以在编辑文本上写一个数字（第一个出现一次，直到我退格然后我可以再次写）所以我想要更改键盘的颜色我尝试了一个代码，它在按下时将键更改为蓝色但我想保持蓝色，例如我按下数字（1234）键盘上的这个数字将颜色变为蓝色并保持这种状态，直到我退格这个数字它变成了他原来的颜色（未压制的颜色） 看看我的代码和图片你会明白的

MainActivty.java

    private CustomKeyboardView mKeyboardView;
private EditText mTargetView;
private Keyboard mKeyboard;
String textContainer = "";
int length = 0;
int prevLength = 0;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);


    mKeyboard = new Keyboard(this, R.xml.keyboard);

    mTargetView = (EditText) findViewById(R.id.target);
    mTargetView.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            showKeyboardWithAnimation();
            return true;
        }
    });

    mKeyboardView = (CustomKeyboardView) findViewById(R.id.keyboard_view);
    mKeyboardView.setKeyboard(mKeyboard);
    mKeyboardView.setPreviewEnabled(false);

    mKeyboardView.setOnKeyboardActionListener(new BasicOnKeyboardActionListener(
                    this));



    mTargetView.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            textContainer = s.toString();
            prevLength = s.length();
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
        }
        @Override
        public void afterTextChanged(Editable s) {
            length = s.length();
                            if(!textContainer.isEmpty()){
                                if(s.length() > 1) {
                                    if(prevLength < length) {
                                        if (!textContainer.contains(s.toString().subSequence(length - 1, length))) {
                                            length = s.length();
                                        } else {
                            mTargetView.getText().delete(length - 1, length);
                        }
                    }
                }
            }else{
                textContainer = s.toString();
            }


        }
    });
