怎样的android设置的EditText光标到文本的结尾 [英] android how to set the EditText Cursor to the end of its text

问题描述

用户必须输入自己的手机号码，手机号码必须是10号，我用 TextWatcher 要做到这一点，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("*");
        }
    }
});

但是，当用户进入第11号的问题是，在EditText上的光标开始从文本的开始，我希望它仍然在最后，如何pelase？

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 pelase?

推荐答案

您有两种选择，两者都应该工作：

You have two options, both should work:

一）

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

B）

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