我在scrollview中實現了viewpager，但viewpager每當到達屏幕的底部邊緣時都會變形，使得scrollview不起作用，viewpager底部的元素不能顯示。這是我的代碼：ViewPager ScrollView無法正常工作
1. Main Acitivity
public class MainActivity extends AppCompatActivity {
ViewPager viewPager;
ViewPager viewPager2;
PagerAdapter adapter2;
private static int currentPage = 0;
private int[] IMAGES = {R.drawable.one, R.drawable.two, R.drawable.three, R.drawable.four};
private ArrayList<Integer> IMAGESArray = new ArrayList<Integer>();
private ScrollView scrollView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.landing_page);
scrollView = (ScrollView) findViewById(R.id.scroll);
viewPager2 = (ViewPager) findViewById(R.id.pager3);
// Pass results to ViewPagerAdapter Class
adapter2 = new FirstViewPagerAdapter(TestActivity.this);
// Binds the Adapter to the ViewPager
viewPager2.setAdapter(adapter2);
init();
}
private void init() {
for(int i=0;i<IMAGES.length;i++)
IMAGESArray.add(IMAGES[i]);
viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(new SecondViewPagerAdapter(TestActivity.this, IMAGESArray));
CircleIndicator indicator = (CircleIndicator) findViewById(R.id.indicator);
indicator.setViewPager(viewPager);
// Auto start of viewpager
final Handler handler = new Handler();
final Runnable Update = new Runnable() {
public void run() {
if (currentPage == IMAGES.length) {
currentPage = 0;
}
viewPager.setCurrentItem(currentPage++, true);
}
};
Timer swipeTimer = new Timer();
swipeTimer.schedule(new TimerTask() {
@Override
public void run() {
handler.post(Update);
}
}, 2500, 2500);
}
}
2. The first view pager adapter
public class FirstViewPagerAdapter extends PagerAdapter {
private Context mContext;
private ViewPager pager=null;
private int images [] = {R.drawable.whiskey, R.drawable.vodka, R.drawable.whiskey, R.drawable.vodka, R.drawable.whiskey};
public FirstViewPagerAdapter(Context context) {
mContext = context;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
LayoutInflater inflater = LayoutInflater.from(mContext);
View itemView = inflater.inflate(R.layout.page, container, false);
ImageView image1 = (ImageView)itemView.findViewById(R.id.image);
image1.setImageResource(images[position]);
((ViewPager) container).addView(itemView);
return itemView;
}
@Override
public void destroyItem(ViewGroup container, int position,
Object object) {
container.removeView((View)object);
}
@Override
public int getCount() {
return(5);
}
@Override
public boolean isViewFromObject(View view, Object object) {
return(view == object);
}
}
3. The second view pager adapter
public class SecondViewPagerAdapter extends PagerAdapter {
private ArrayList<Integer> images;
private LayoutInflater inflater;
private Context context;
public SecondViewPagerAdapter(Context context, ArrayList<Integer> images) {
this.context = context;
this.images=images;
inflater = LayoutInflater.from(context);
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
@Override
public int getCount() {
return images.size();
}
@Override
public Object instantiateItem(ViewGroup view, int position) {
View myImageLayout = inflater.inflate(R.layout.view_pager_item, view, false);
ImageView myImage = (ImageView) myImageLayout.findViewById(R.id.flag);
myImage.setImageResource(images.get(position));
view.addView(myImageLayout, 0);
return myImageLayout;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view.equals(object);
}}
