Textview act like a terminal

Hello I am trying to get text to display like it does in terminal or cmd. And by that I mean a window of text that with each input makes a new line and then displays the bottom line of the

TextView
, and there would be a set amount of lines always on the screen.

It sounded easy to do, but now that I started I'm not sure how to do it.

I tried putting a
TextView
in a
ScrollView
like this

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:weightSum="100" >

<ScrollView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1">

<TextView android:id="@+id/tv1"
android:layout_width="wrap_content"
android:minLines="11"
android:maxLines="11"
android:layout_height="wrap_content"/>
</ScrollView>

<EditText
android:id="@+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="10" >

<requestFocus />
</EditText>

<Button
android:id="@+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="10"
android:onClick="buttonclick"
android:text="Button" />

</LinearLayout>


and then

sss=et1.getText().toString();
tv1.append("\n"+sss);


to add new lines

This all works but I really have no idea how to make the
TextView
go to the bottom, right now it just cuts off when I hit the max number of lines.

I definitely don't expect anyone to write my program for me. I am here to learn

Thanks for your time!

Answer

Call fullScroll(View.FOCUS_DOWN) on the ScrollView after appending the text.
