Java EditText-setText（）方法不工作-StackOverFlow异常,java,android,android-edittext,Java,Android,Android Edittext,我在想为什么这行代码会出现StackOverFlow异常时遇到了一些问题： mPassword.setText(phone); 我试图格式化一个数字，而用户正在键入它，并采取格式化的数字，并将其设置为EditText小部件。我如何解决这个问题代码如下： @Override public void onTextChanged(CharSequence s, int start, int before, int count) { //Toast.makeText

我在想为什么这行代码会出现StackOverFlow异常时遇到了一些问题：

 mPassword.setText(phone);

我试图格式化一个数字，而用户正在键入它，并采取格式化的数字，并将其设置为EditText小部件。我如何解决这个问题

代码如下：

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        //Toast.makeText(getApplicationContext(), "In onTextChanged() Method", Toast.LENGTH_SHORT).show();
        if (s.length() != 0) {
            switch (et.getId()) {
            case R.id.etUsername: {

            }
            break;

            case R.id.etPassword: {
                phone = formatPhoneNumber(phone);
                Log.i("PHONE", "Phone NUMB IS:"+phone);
                mPassword.setText(phone);  //THE ERROR HAPPENS HERE
            }
            }
        }
    }             

public String formatPhoneNumber(String phoneNumber) {
    Toast.makeText(getApplicationContext(), "In formatPhoneNumber() Method", Toast.LENGTH_SHORT).show();
    final StringBuffer sbPhone = new StringBuffer(phoneNumber);

    if (sbPhone.length() == 9) {
        //phoneNumber.substring(8, '-');
        //phoneNumber.insert(8, '-');
        if (sbPhone.indexOf("-") == -1) {
            sbPhone.insert(8, "-");
        }
    }
    else if (sbPhone.length() == 8) {
        //phoneNumber.replace("-", "");
        if (sbPhone.indexOf("-") != -1) {
            sbPhone.delete(sbPhone.indexOf("-"), sbPhone.indexOf("-"));
        }
    }
 }

以下是错误：
