AndroidでハッカーのターミナルっぽいViewを作る

TextViewへのappendはHandlerを使う
http://stackoverflow.com/questions/6159686/android-does-not-append-text-to-textview-properly

Handler h = new Handler(context.getMainLooper());

h.post(new Runnable() {
    @Override
    public void run() {
         txview.append("Text"+message.getFrom()+"\n"+message.getBody()+"\n"); 
    }
});

TextViewに付け加えた後はScrollViewの最後にフォーカスを移動する
http://stackoverflow.com/questions/9165827/how-to-keep-a-scrollview-to-be-scrolled-to-the-bottom

myScrollView.postDelayed(new Runnable() {

   @Override
   public void run() {
     sv.fullScroll(View.FOCUS_DOWN);
   }
}, 100);
