Adding a new TextView into a layout from an EditText and Button

Question

The app I am working on has an EditText at the bottom (along with a button). When that button is pressed, I am trying to have the EditText converted into a TextView and placed inside a linear layout. How can I go about this? Each example I've looked at hasn't worked for me.

I've tried this code:

public class Notes extends Fragment {

    LinearLayout llNotes;
    Button butNotes;
    EditText etNotes;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.notes, container, false);

        return rootView;


    }

    public void sendText(View view){
        etNotes=(EditText)findViewById(R.id.etNotes);
        String message=etNotes.getText().toString();
        llNotes=(LinearLayout)findViewById(R.id.llNotes);
        TextView text = new TextView(this);
        text.setText(message);
        llNotes.addView(text);

    }
}

The linear layout is inside of a scrollview inside of a frame layout. For the above code, I can't even type in the sendText part without it giving me an error (the sendText is an android:OnClick). Sorry I'm new to Android.

At the moment, in the "sendText" method, all the findViewById are errored as well as "new TextView(this)"

Answer 1

"findViewById" doesn't exist in Fragment...
You should use rootView.findViewById(...) to get your target view.
Also, the android:onClick attribute in xml file will find the same function name in Activity but Fragment.

So you should define your onClick function in Activity.
But if you want define the onClick function in Fragment, remove the android:onClick attribute in xml file, and use Button.setOnClickListener(OnclickListener) function to setup the OnClickListener of Button in Fragment.

Here is some example:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.notes, container, false);
    llNotes=(LinearLayout)rootView.findViewById(R.id.llNotes);
    etNots=(EditText)rootView.findViewById(R.id.etNotes);

    etNotes.setOnClickListener(notesListener);

    return rootView;
}

private OnClickListener notesListener = new OnClickListener() {
    public void onClick(View view) {
        String message=etNotes.getText().toString();

        TextView text = new TextView(getActivity());
        text.setText(message);
        llNotes.addView(text);
    }
};

And remove the 'android:onClick="sendText"' in your layout xml file.
