android ViewPager 竖向滑动

VerticalViewPager的源代码在 https://github.com/jiangkia/javaLibrary ，在javalibrary/android/ui包下。下面是调用VerticalViewPager的demo。

public class MainActivity extends Activity {

private List<String> list;
private int[] colors = new int[]{
Color.BLACK,Color.BLUE,Color.CYAN,Color.DKGRAY,Color.GRAY,
Color.GREEN,Color.LTGRAY,Color.MAGENTA,Color.RED,Color.TRANSPARENT
};

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

list = new ArrayList<String>();
for(int i = 0; i < 10; i++){
list.add(String.valueOf(i));
}

MyAdapter adapter = new MyAdapter();
VerticalViewPager viewPager = new VerticalViewPager(this);
viewPager.setAdapter(adapter);
setContentView(viewPager);

// setContentView(R.layout.activity_main);
//
// if (savedInstanceState == null) {
// getSupportFragmentManager().beginTransaction()
// .add(R.id.container, new PlaceholderFragment()).commit();
// }
}

class MyAdapter extends VerticalPagerAdapter{

@Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}

@Override
public boolean isViewFromObject(View view, Object object) {
// TODO Auto-generated method stub
return view == object;
}

@Override
public Object instantiateItem(ViewGroup container, int position) {
// TODO Auto-generated method stub
// return super.instantiateItem(container, position);
TextView textView = new TextView(MainActivity.this);
textView.setBackgroundColor(colors[position]);
textView.setText(list.get(position));
textView.setTextSize(300);
textView.setTextColor(Color.RED);
textView.setGravity(Gravity.CENTER);
((VerticalViewPager)container).addView(textView);
return textView;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
// TODO Auto-generated method stub
// super.destroyItem(container, position, object);
}
};
}
