scroll - Making TextView scrollable on Android



I am displaying text in a textview that appears to be too long to fit
into one screen. I need to make my TextView scrollable. How can I do
that?



Here is the code:




final TextView tv = new TextView(this);
tv.setBackgroundResource(R.drawable.splash);
tv.setTypeface(face);
tv.setTextSize(18);
tv.setTextColor(R.color.BROWN);
tv.setGravity(Gravity.CENTER_VERTICAL| Gravity.CENTER_HORIZONTAL);
tv.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent e) {
Random r = new Random();

int i = r.nextInt(101);
if (e.getAction() == e.ACTION_DOWN) {
tv.setText(tips[i]);
tv.setBackgroundResource(R.drawable.inner);
}
return true;
}
});
setContentView(tv);


Answer



You don't need to use a ScrollView actually.



Just set the



android:scrollbars = "vertical"


properties of your TextView in your layout's xml file.




Then use:



yourTextView.setMovementMethod(new ScrollingMovementMethod());



in your code.



Bingo, it scrolls!
