View paper only one minute

ယခုပြောပြမှာကတော့view paperပါ

ပထမဦးစွာlinearတစ်ခုထည့်ပါမယ်

on createမှာadd source directly

ဖြင့်ယခုcodeအားထည့်ပေးပါ

//Copied From Universal SketchCode Premium(6.1).

final androidx.viewpager.widget.ViewPager viewPager = new androidx.viewpager.widget.ViewPager(this);

viewPager.setLayoutParams(new ViewGroup.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));

viewPager.setBackgroundColor(Color.WHITE);

MyPagerAdapter adapter = new MyPagerAdapter();

viewPager.setAdapter(adapter);

viewPager.setCurrentItem(0);

linear1.addView(viewPager);

viewPager.addOnPageChangeListener(new androidx.viewpager.widget.ViewPager.OnPageChangeListener() { public void onPageSelected(int position) { 

if (position == 0) {

}

if (position == 1) {

}

if (position == 2) {

}

if (position == 3) {

}

 }

@Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { }

@Override public void onPageScrollStateChanged(int state) { }

 });

}

private class MyPagerAdapter extends androidx.viewpager.widget.PagerAdapter {

public int getCount() {

return 4;

}

public Object instantiateItem(View collection, int position) {

LayoutInflater inflater = (LayoutInflater) collection.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

int resId = 0;

switch (position) {

case 0:

resId = R.layout.left;

break;

case 1:

resId = R.layout.farleft;

break;

case 2:

resId = R.layout.middle;

break;

case 3:

resId = R.layout.right;

break;

}

View view = inflater.inflate(resId, null);

((androidx.viewpager.widget.ViewPager)collection).addView(view, 0);

view.setTag("myview" + position);

return view;

}

@Override

public void destroyItem(View arg0, int arg1, Object arg2) {

((androidx.viewpager.widget.ViewPager) arg0).removeView((View) arg2);

}

@Override

public boolean isViewFromObject(View arg0, Object arg1) {

return arg0 == ((View) arg1);

}

@Override

public Parcelable saveState() {

return null;

}

ထို့နောက်custom view 4ဆောက်ပါ

custom တစ်ခုချင်းဆီမှာlinearတစ်ခုဆီထည့်ပါ

ထို့နောက်runလိုက်ပါဒါ‌ဆိုview paperရပါပြီ
