So this is my code in java:

 Button bt1 = (Button) findViewById(R.id.button1);

 bt1.setOnClickListener(new View.OnClickListener() {



        @Override

        public void onClick(View view) {

            TextView txt1 = (TextView) findViewById(R.id.here);

I only have one xml file and it has a scrollable layout with 1 button and a lot of textview. I'm wondering how I can go to a specific textview using a button. I only want my button to go to the last textview(findViewById(R.id.here)) in my xml file once it's clicked. How can I do that? Can you please help me? Thank you very much.

This is my xml file:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical"

xmlns:tools="http://schemas.android.com/tools"

tools:context="com.example.search.MainActivity" >



<ScrollView

    android:id="@+id/scrollView1"

    android:layout_width="fill_parent"

    android:layout_height="match_parent" >



    <LinearLayout

        android:layout_width="fill_parent"

        android:layout_height="389dp"

        android:orientation="vertical" >



        <Button

            android:id="@+id/button1"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:text="Button" />



            <TextView

                android:id="@+id/here1"

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:layout_alignParentBottom="true"

                android:layout_marginTop="400dp"

                android:text="HERE!" />



             <TextView

                android:id="@+id/here2"

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:layout_alignParentBottom="true"

                android:layout_marginTop="400dp"

                android:text="HERE!" />



              <TextView

                android:id="@+id/here3"

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:layout_alignParentBottom="true"

                android:layout_marginTop="400dp"

                android:text="HERE!" />



               <TextView

                android:id="@+id/here"

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:layout_alignParentBottom="true"

                android:layout_marginTop="400dp"

                android:text="Right here" />



    </LinearLayout>



</ScrollView>

I want to go to the last textview once the button is clicked. Thankyou

you can scroll to any widget in scroll view by this code:(kotlin syntax, if you want change to Java):

fun scrollToView(scrollViewParent: ScrollView, view: View) {

    val childOffset = Point()

    getDeepChildOffset(scrollViewParent, view.parent, view, childOffset)

    scrollViewParent.smoothScrollTo(0, childOffset.y)

}



private fun getDeepChildOffset(mainParent: ViewGroup, parent: ViewParent, child: View, accumulatedOffset: Point) {

    val parentGroup = parent as ViewGroup

    accumulatedOffset.x += child.left

    accumulatedOffset.y += child.top

    if (parentGroup == mainParent) {

        return

    }

    getDeepChildOffset(mainParent, parentGroup.parent, parentGroup, accumulatedOffset)

}

then you just call scrollToView by each view that you want to scroll to it

im still not understand you very well check this answer about what i understand from you

Button bt1 = (Button) findViewById(R.id.button1);

TextView txt1 = (TextView) findViewById(R.id.here);

ScrollView scrollv = (ScrollView)findViewById(R.id.scrollView1);

bt1.setOnClickListener(new View.OnClickListener() {



    @Override

    public void onClick(View view) {

     Toast.makeText(getApplicationContext(),txt1.getText().toString(),Toast.LENGTH_LONG).show();

     scrollv.scrollTo(0, scrollv.getBottom());

now if that not your answer try to explain me more
