ScrollView auto scroll after particular field in android

Question

This code helps me to auto scrolling on click function but when the edit text4 is clicked it is scrolled up only one field above. I want that field to go to the top of the screen. I used scroll up, scroll by, scroll To, everything but all gives the same result. Would you please help.

package com.example.scrollview;

import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.EditText;
import android.widget.ScrollView;


public class MainActivity extends Activity{
EditText edtText4,edtText8;
ScrollView scrollView;
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    scrollView = (ScrollView)findViewById(R.id.scv);

    edtText4 = (EditText)findViewById(R.id.editText4);
    edtText8 = (EditText)findViewById(R.id.editText8);  

    edtText4.setOnTouchListener(selectedFieldTouchListener);
    edtText8.setOnTouchListener(selectedFieldTouchListener);

}
private OnTouchListener selectedFieldTouchListener = new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        int top1 = 0;
        switch (v.getId()) {
        case R.id.editText4:
            top1 = edtText4.getTop();  
            break;
        case R.id.editText8:
            top1 = edtText8.getTop();
            break;
        }
        final int top = top1;
        scrollView.postDelayed(new Runnable() {//must be in postDelayed otherwise wont work

            @Override
            public void run() {
                scrollView.scrollTo(0, edtText4.getTop());
            }
        }, 100);

        return false;
    }
};

}

I tried that code but there is no change, while scrolling only it goes up or down — Zarin, Jun 24 '14 at 11:24

This assumes that the EditTexts are direct children of the ScrollView

private OnTouchListener selectedFieldTouchListener = new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            int top1 = 0;
            switch (v.getId()) {
            case R.id.editText4:
                top1 = edtText4.getTop();
                break;
            case R.id.editText8:
                top1 = edtText8.getTop();
                break;
            }
            final int top = top1;
            scrollView.postDelayed(new Runnable() {//must be in postDelayed otherwise wont work

                @Override
                public void run() {

                    scrollView.scrollTo(0, top);
                }
            }, 100);

            return false;
        }
    };

and then add the Touch Listener to your EditTexts

    edtText4.setOnTouchListener(selectedFieldTouchListener);
    edtText8.setOnTouchListener(selectedFieldTouchListener);

what will you do if he use nex key from the keyboard??!! you need to consider that too. — Jithu, Jun 24 '14 at 11:07
