Question:
I have a simple layout
as shown below which has a horizontal ScrollView
when going over the TextView
boundary.
But I would like that when inserting text the focus of the TextView
would always be on the last value inserted and not need to scroll the bar to see the last value inserted.
Like an automatic scroll to follow the values entered.
And go back with the bar manually to the beginning if you need to.
Does anyone have an idea how to do it?
Activity :
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textview = (TextView) findViewById(R.id.textview);
textview.setMovementMethod(new ScrollingMovementMethod());
}
}
xml:
<HorizontalScrollView
android:id="@+id/horizontalScrollView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right">
<TextView
android:id="@+id/display0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:editable="false"
android:gravity="center|right" />
</HorizontalScrollView>
</LinearLayout>
Answer:
Try doing like this:
ScrollView sc = ((ScrollView) R.findViewById(R.id.scroll);
sc.post(new Runnable() {
public void run() {
sc.fullScroll(ScrollView.FOCUS_DOWN);
}
});
