Im trying to use Neil Davies's CoverFlow Widget v2 as a fragment activity.
Im expecting something like this
Instead Im getting this
Clearly something is wrong in my implementation, but since Im seeing no errors or crashes..Im kinda lost as to where to look. Anywho below is the java and xml code
SampleTabsDefault.java
public class SampleTabsDefault extends FragmentActivity {
private static final String[] CONTENT = new String[] { "Tab 1", "Tab 2", "Tab 3", "Tab 4", "Tab 5", "Tab 6",
"Tab 7","Tab 8","Tab 9","Tab 10","Tab 11","Tab 12","Tab 13","Tab 14"
,"Tab 15","Tab 16"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_tabs_2);
FragmentPagerAdapter adapter = new MyNavTabs(getSupportFragmentManager());
ViewPager pager = (ViewPager)findViewById(R.id.pager);
pager.setAdapter(adapter);
TabPageIndicator indicator = (TabPageIndicator)findViewById(R.id.indicator);
indicator.setViewPager(pager);
}
class MyNavTabs extends FragmentPagerAdapter {///////maybe this needs to be in fragment to to call CoverFlowExampleFragment
public MyNavTabs(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch(position)
{
case 0:
TestFragment fragment = new TestFragment();
return fragment;
case 1:
TestFragment2 fragment2 = new TestFragment2();
return fragment2;
}
TestFragment3 fragment3 = new TestFragment3();
return fragment3;
}
@Override
public CharSequence getPageTitle(int position) {
return CONTENT[position % CONTENT.length].toUpperCase();
}
@Override
public int getCount() {
return CONTENT.length;
}
}public void onBackPressed() {
finish();
super.onBackPressed();
}
