Android - Add textview to layout when button is pressed

Question

So right now I have a text field with a button (add+) below it.

I would like to make it so every time text is entered into the Text Field, and the Add button is pressed, a new text view is added to a vertical layout below it with the text that the user typed in the field.

I do not want to simply make a text view invisible, then visible when clicked, because I would like them to be able to add more than one text view with whatever text they type.

This code contains what you want. (The view show an EditText and a Button, after you click on the button the text will add to the LinearLayout)

    private LinearLayout mLayout;
private EditText mEditText;
private Button mButton;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    mLayout = (LinearLayout) findViewById(R.id.linearLayout);
    mEditText = (EditText) findViewById(R.id.editText);
    mButton = (Button) findViewById(R.id.button);
    mButton.setOnClickListener(onClick());
    TextView textView = new TextView(this);
    textView.setText("New text");
}

private OnClickListener onClick() {
    return new OnClickListener() {

        @Override
        public void onClick(View v) {
            mLayout.addView(createNewTextView(mEditText.getText().toString()));
        }
    };
}

private TextView createNewTextView(String text) {
    final LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    final TextView textView = new TextView(this);
    textView.setLayoutParams(lparams);
    textView.setText("New text: " + text);
    return textView;
}

And the xml is:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/linearLayout">
 <EditText 
    android:id="@+id/editText"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
 />
<Button 
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Add+"
/>
