EditText获取值以传递Textview

Question

I am working on an activity in which I have taken edittext and textview. I have to get integer value from edittext and set it on textview.

I have to take 10-digit number(mobile no) on edittext and as soon as the edittext column gets 10-digits,its automatically sets 10-digit number on textview within the same activity.

I have implemented in this manner

1. Getting value on edittext using

    Integer.parseInt(edittext.getText().toString()); 

   in a String str.

2. Applying condition to it (str.length == 10) and getting it on textview.

As the above process is not working so try to help me friends.

I am working on this code:

public class MobileNo extends Activity {

        EditText et;
        TextView tv;
        int i;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);

            et = (EditText) findViewById(R.id.edit);
            tv = (TextView) findViewById(R.id.text1);

            et.getText().toString();

            et.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 textVal) {
                    // TODO Auto-generated method stub
                    Editable inputNo = textVal;
                    if (inputNo.length() == 10) {
                        tv.setText(inputNo);
                    }

                }
            });

        }
    }

Answer 1

I would try:

            @Override
            public void afterTextChanged(Editable textVal) {
                String inputNo = textVal.toString();
                if (inputNo.length() == 10) {
                    tv.setText(inputNo);
                }

            }

If your phone number is formatted like "(800) 549-2992" or "800-549-2992" and you only wants the numbers then you'd have to do the following:

            @Override
            public void afterTextChanged(Editable textVal) {
                // takes out all non-digits from string
                String inputNo = textVal.toString().replaceAll("[^\\d]","");
                if (inputNo.length() == 10) {
                    tv.setText(inputNo);
                }

            }
