Question

I have a listview contain items Apple, Banana, Orange …in second screen activity
when I click on particular item on Apple it navigates to Details screen

here output has to appear like by clicking on –> Apple ..if I swipe page then banana and for next swipe Orange

Apple–>Banana–>Orange

If I click on Banana –>then it has to appear like Banana then left swipe Apple ..and for right swipe…Orange.

So which item I clicked on(Banana) listview in second screen it has to appear on details screen and for left swipe previous list item and for right swipe next item in the list.

Banana–>for left swipe Apple
–>for right swipe Orange

If I click on Orange –>then it has to appear like Orange then left swipe Banana ..and for next left swipe…Orange.
Banana

Orange–>for left swipe Banana—>for next left swipe–>Apple

but am getting output like Apple–>Banana–>Orange for all the cases of each item clicked on the listview….

Answer 1

In the OnItemClickListener for your list of fruits you should pass the position of the selected fruit in the Intent so you can know in the details activity which fruit was clicked, something like this:

Intent detailIntent =new Intent(SecondScreen.this, Details.class);          
detailIntent.putExtra("fruitPosition", arg2);
startActivity(detailIntent); 

Then in your details activity you would retrieve that number and position the ViewPager accordingly:

setContentView(R.layout.detail);    
app = ((MyApplication) getApplicationContext());
pager = (ViewPager) findViewById(R.id.pager);
FragmentManager fm = getSupportFragmentManager();      
pagerAdapter = new MyFragmentPagerAdapter(fm,app.totalvalue);   
pager.setAdapter(pagerAdapter);
Intent startIntent = getIntent();
int fruitPosition = startIntent.getIntExtra("fruitPosition", 0);
pager.setCurrentItem(fruitPosition);
