Question

I’m new in eclipse and I have got a project that can add and edit name , age , etc using a textview maybe same like a contacts list

in here i have 3 class.. 1 for arraylist data 1 for view holder and the last is my activity
the problem is when i use a parseint for the age.. if i using string there is no any problem
when i using a parseint and after i fill in name and age and press add button it show me the application has stopped unexpectedly..

this is some of the code

public void Save(View view){
        @SuppressWarnings("unchecked")

        ArrayAdapter<Data> adapter = (ArrayAdapter<Data>)getListAdapter();

        EditText Name = (EditText)findViewById(R.id.Name);
        EditText Age = (EditText)findViewById(R.id.Age);

        String name = Name.getText().toString();
        int age = Integer.parseInt(Age.getText().toString());

        if (edit)
        {
            Data temp = adapter.getItem(position);
            temp.setData(name,age);
        }
        else
        {
            Data temp = new Data(name, age);
            friends.add(temp);
        }
        viewflipper.showNext();
    }

that int age = Integer.parseInt(Age.getText().toString()); i don’t know whats wrong with that code if i use string its work and i have already change my xml for my textview to this
android:inputType="number" > but it also same error

this is the logcat
