问题描述

用户必须输入他的手机号码,手机号码必须是10个号码,我使用TextWatcher来做到这一点,像这样

The user has to enter his mobile number, the mobile number has to be 10 numbers, I used TextWatcher to do that, like this

et_mobile.addTextChangedListener(new TextWatcher() {

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

    }

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

    }

    @Override
    public void afterTextChanged(Editable s) {
        // TODO Auto-generated method stub
        if (et_mobile.getText().toString().length() > 10) {
            et_mobile.setText(et_mobile.getText().toString()
                    .subSequence(0, 10));
            tv_mobileError.setText("Just 10 Number");
        }else{
            tv_mobileError.setText("*");
        }
    }
});

但问题是当用户输入第11个数字时,edittext的光标从文本的开头开始,我希望它仍然在末尾,怎么办?

but the problem is when the user enters the 11th number, the cursor of the edittext starts from the beginning of the text, I want it to still at the end, how?

推荐答案

你有两个选择,都应该工作:

You have two options, both should work:

一)

editText.setText("Your text");
editText.setSelection(editText.getText().length());

b)

editText.setText("");    
editText.append("Your text");
