One of my layouts inside of my ViewPager has a button. "R.layout.add_site". I would like the option of hitting the button and it scroll to the specific page for me. I already have the option to swipe to the specific page, but I would like to have both.
Now I'm sure there's a way to do that, but for some reason, I cannot figure it out.
You'll see that I've made an attempt , but just dont know what method to call in order to make it scroll to the desired page. Which is R.layout.main.
Here's my code.
public class fieldsActivity extends Activity {
Button addSiteButton;
Button cancelButton;
Button signInButton;
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// to create a custom title bar for activity window
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
setContentView(R.layout.fields);
// use custom layout title bar
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.topbar);
Pager adapter = new Pager();
ViewPager mPager = (ViewPager) findViewById(R.id.fieldspager);
mPager.setAdapter(adapter);
mPager.setCurrentItem(1);
addSiteButton = (Button) findViewById(R.id.addSiteButton);
addSiteButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Don't know what method to call!?
}
});
cancelButton = (Button) findViewById(R.id.cancel_button);
signInButton = (Button) findViewById(R.id.sign_in_button);
}
private class Pager extends PagerAdapter {
public int getCount() {
return 3;
}
@Override
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.field01;
break;
case 1:
resId = R.layout.add_site;
break;
case 2:
resId = R.layout.main;
break;
}
View view = inflater.inflate(resId, null);
((ViewPager) collection).addView(view, 0);
return view;
}
@Override
public void destroyItem(View arg0, int arg1, Object arg2) {
((ViewPager) arg0).removeView((View) arg2);
}
@Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == ((View) arg1);
}
@Override
public Parcelable saveState() {
return null;
}
}
}
Any help is appreciated!
call :
mPager.setCurrentItem(2);
in your onClick() method, or for a smoother scroll:
mPager.setCurrentItem(2, true);
