Try this code.

<HorizontalScrollView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/scroll" > <TextView android:id="@+id/textViewId" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scrollHorizontally="true" android:text="your_big_string"/> </HorizontalScrollView>

In you activity.java, add this

final HorizontalScrollView scrollView = (HorizontalScrollView) findViewById(R.id.scroll); scrollView.postDelayed(new Runnable() { public void run() { scrollView.fullScroll(HorizontalScrollView.FOCUS_RIGHT); } }, 100L);

The edited ans serves the purpose you asked for. didn't you remove singleline, gravity, layout_gravity from your textView? these attribute may cause problem in your case. I suggest you not to edit your textView according to my answer, just copy+paste the sample code and see if it works.

then you should add your whole xml and describe your needs more specifically (ex: why the gravity is so important?).
