在Android editText中同时使用keyListener和textChangedListener

我试着两者兼用

editPhoneNumber.setKeyListener(new KeyListener() 

及

但它们似乎相互阻塞，我的编辑文本不再可编辑

谢谢你的帮助

我正在尝试将输入格式化为用户类型：

输入：555111233 格式化输入：555 111 22 33

格式化部分工作得很好，但我尝试添加KeyListener的原因是当用户试图通过按delete键进行删除时，以及当输入长度变为（比方说）12个字符时，TextChangedListener总是在文本末尾加上一个字符来中断用户的删除。这就是为什么我试图在输入为delete键时禁用TextChangedListener

boolean isResetClicked;
EditText editPhoneNumber;
Button buttonReset;

protected void onCreate(Bundle savedInstanceState)
{
    editPhoneNumber = (EditText) findViewById(R.id.editPhoneNumber);
    buttonReset = (Button) findViewById(R.id.buttonResetPhoneNumber);
    buttonReset.setOnClickListener(new OnClickListener()
    {

        @Override
        public void onClick(View v)
        {
            isResetClicked = true;
            editPhoneNumber.getText().clear();
            isResetClicked = false;
        }
    });

    editPhoneNumber.setKeyListener(new KeyListener()
    {

        @Override
        public boolean onKeyUp(View view, Editable text, int keyCode,
                KeyEvent event)
        {
            if (keyCode == KeyEvent.KEYCODE_DEL)
            {
                isResetClicked = true;
            }
            else
                isResetClicked=false;
            return false;
        }

        @Override
        public boolean onKeyOther(View view, Editable text, KeyEvent event)
        {
            // TODO Auto-generated method stub
            return false;
        }

        @Override
        public boolean onKeyDown(View view, Editable text, int keyCode,
                KeyEvent event)
        {

            return false;
        }

        @Override
        public int getInputType()
        {
            // TODO Auto-generated method stub
            return 0;
        }

        @Override
        public void clearMetaKeyState(View view, Editable content,
                int states)
        {
            // TODO Auto-generated method stub

        }
    });

    editPhoneNumber.addTextChangedListener(new TextWatcher()
    {

        @Override
        public void onTextChanged(CharSequence s, int start, int before,
                int count)
        {
            String str;

            if (!isResetClicked)
            {
                if (s.length() == 0)
                {
                    editPhoneNumber.setText("(");
                }
                if (s.length() == 1)
                {
                    str = editPhoneNumber.getText().toString();
                    editPhoneNumber.setText("(" + str);
                    editPhoneNumber.setSelection(editPhoneNumber.getText()
                            .length());
                }
                if (s.length() == 4)
                {
                    str = editPhoneNumber.getText().toString();
                    editPhoneNumber.setText(str + ") ");
                    editPhoneNumber.setSelection(editPhoneNumber.getText()
                            .length());
                }
                if (s.length() == 9)
                {
                    str = editPhoneNumber.getText().toString();
                    editPhoneNumber.setText(str + " ");
                    editPhoneNumber.setSelection(editPhoneNumber.getText()
                            .length());
                }
                if (s.length() == 12)
                {
                    str = editPhoneNumber.getText().toString();
                    editPhoneNumber.setText(str + " ");
                    editPhoneNumber.setSelection(editPhoneNumber.getText()
                            .length());
                }

            }

        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after)
        {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable s)
        {
        }
    });

编辑2：

即使我仍然无法理解为什么两个事件侦听器会阻止我的edittext，我还是通过修改代码解决了问题：

@Override
        public void onTextChanged(CharSequence s, int start, int before,
                int count)
        {
            String str;
            /*Log.i("ED",
                    "LengthBefore before (lengthBefore = lengthAfter;): "
                            + String.valueOf(lengthBefore));*/
            lengthBefore = lengthAfter;
            lengthAfter = s.length();
            /*Log.i("ED",
                    "LengthBefore after (lengthBefore = lengthAfter;): "
                            + String.valueOf(lengthBefore));*/
            if ((lengthBefore < lengthAfter) || lengthBefore == 0)
            {
                if (!isResetClicked)
                {
                    if (s.length() == 0)
                    {
                        editPhoneNumber.setText("(");
                    }
                    if (s.length() == 1)
                    {
                        str = editPhoneNumber.getText().toString();
                        editPhoneNumber.setText("(" + str);
                        editPhoneNumber.setSelection(editPhoneNumber
                                .getText().length());
                    }
                    if (s.length() == 4)
                    {
                        str = editPhoneNumber.getText().toString();
                        editPhoneNumber.setText(str + ") ");
                        editPhoneNumber.setSelection(editPhoneNumber
                                .getText().length());
                    }
                    if (s.length() == 9)
                    {
                        str = editPhoneNumber.getText().toString();
                        editPhoneNumber.setText(str + " ");
                        editPhoneNumber.setSelection(editPhoneNumber
                                .getText().length());
                    }
                    if (s.length() == 12)
                    {
                        str = editPhoneNumber.getText().toString();
                        editPhoneNumber.setText(str + " ");
                        editPhoneNumber.setSelection(editPhoneNumber
                                .getText().length());
                    }

                }
            }
            lengthAfter = s.length();
            /*Log.i("ED", "LengthAfter after (lengthAfter = s.length();): "
                    + String.valueOf(lengthAfter));
            Log.i("ED", "LengthBefore: " + String.valueOf(lengthBefore));
            Log.i("ED", "LengthAfter: " + String.valueOf(lengthAfter));*/

        }

当用户试图删除字符时，新的长度将比旧的长度短。因此，我通过以下方式阻止代码检查长度：

if ((lengthBefore < lengthAfter) || lengthBefore == 0)

你有更多的示例代码吗？你的密钥侦听器和文本更改侦听器在做什么，使你认为它们在互相阻止？用另一种方法解决它，请检查编辑2。

if ((lengthBefore < lengthAfter) || lengthBefore == 0)
