android how to set the EditText Cursor to the end of its text

Question

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("*");
        }
    }
});

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?

Solution 1

You have two options, both should work:

a)

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

b)

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

Solution 2

/**
 * Set pointer to end of text in edittext when user clicks Next on KeyBoard.
 */
View.OnFocusChangeListener onFocusChangeListener = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View view, boolean b) {
        if (b) {
            ((EditText) view).setSelection(((EditText) view).getText().length());
        }
    }
};

mEditFirstName.setOnFocusChangeListener(onFocusChangeListener);
mEditLastName.setOnFocusChangeListener(onFocusChangeListener);

It work good for me!
