我已经使用ActionBarSherlock实现了ViewPagerIndicator。
现在,我想在创建viewpager后在viewpager中打开一个特定的片段。通常你应该使用setCurrentItem(pageid)或setViewPager(mPager,pageid);
但这不起作用:(如果我想在viewpager中打开片段2,那么 viewpager指示器显示片段2显示,但实际上片段1(标准)显示在viewpager中。
我有以下代码:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_tabs);
mAdapter = new ColofonFragmentAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mIndicator = (TabPageIndicator)findViewById(R.id.indicator);
String page = "";
page = getIntent().getStringExtra("page");
int pageid = 0;
if(page.equals("contact")) { pageid = 0; }
else if(page.equals("colofon")) { pageid = 1; }
else if(page.equals("disclaimer")) { pageid = 2; }
mIndicator.setViewPager(mPager, pageid); // Doesn't work...
//mIndicator.setCurrentItem(pageid); // Doesn't work...
}
class ColofonFragmentAdapter extends FragmentPagerAdapter implements TitleProvider {
ArrayList<Fragment> fragments = new ArrayList<Fragment>();
ArrayList<String> titels = new ArrayList<String>();
public ColofonFragmentAdapter(FragmentManager fm) {
super(fm);
fragments.add(new LayoutFragment(R.layout.colofon_contactgegevens));
titels.add("Contact");
fragments.add(new LayoutFragment(R.layout.colofon_colofon));
titels.add("Colofon");
fragments.add(new LayoutFragment(R.layout.colofon_disclaimer));
titels.add("Disclaimer");
}
@Override
public Fragment getItem(int position) {
return fragments.get(position);
}
@Override
public int getCount() {
return fragments.size();
}
@Override
public String getTitle(int position) {
return titels.get(position);
}
}
您能告诉我应该使用哪种方法来更改初始页面吗? 谢谢!
答案 0 :(得分:0)
我认为这是由setCurrentItem()引起的错误 https://github.com/JakeWharton/Android-ViewPagerIndicator/pull/76
它已经解决了^^
