package com.genanyang.day04self_scrollview;

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.ImageView;

import android.widget.ScrollView;

public class MainActivity extends Activity {

private ScrollView scrollView = null;

private ImageView imageView = null;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

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

imageView = (ImageView) findViewById(R.id.imageView_MainActivity);

imageView.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

scrollView.smoothScrollBy(0,100);

}

});

}
