我正在开发一个 Android 应用程序。我已经附加了 8 个 fragment 和一个用于滑动的 viewpager。它可以工作，但是当滑动 stackoverflow 错误时出现。以下是我的fragmentactivity。
public class HomeScreen extends FragmentActivity {
public InsuranceFragmentAdapter mAdapter;
private ViewPager mPager;
public String value;
public PageIndicator mIndicator;
public static int cPosition = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.themed_circles);
mAdapter = new InsuranceFragmentAdapter(getSupportFragmentManager(),
HomeScreen.this);
mPager = (ViewPager) findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mIndicator = (CirclePageIndicator) findViewById(R.id.indicator);
mIndicator.setViewPager(mPager);
// mIndicator.setCurrentItem(2);
mIndicator
.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
}
@Override
public void onPageScrolled(int position,
float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
}
我的适配器类如下
public class InsuranceFragmentAdapter extends FragmentPagerAdapter {
Context contx;
public InsuranceFragmentAdapter(FragmentManager fm, Context ctx) {
super(fm);
this.contx = ctx;
}
@Override
public Fragment getItem(int position) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentPolicyListing.class.getName());
break;
case 1:
fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentBasicPersonal.class.getName());
break;
case 2:
fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentationNomineeDetails.class.getName());
break;
case 3:
fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentFamilyHistory.class.getName());
break;
case 4:
fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentPolicyDetails.class.getName());
break;
case 5:
fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentFemale.class.getName());
break;
case 6:
fragment = Fragment.instantiate(contx, com.lic.fragments.Fragmentmedical.class.getName());
break;
case 7:
fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentCheckList.class.getName());
break;
}
return fragment;
}
@Override
public int getCount() {
// Show 3 total pages.
return 8;
}
// @Override
// public CharSequence getPageTitle(int position) {
// return TestFragmentAdapter.CONTENT[position % CONTENT.length];
// }
// @Override
// public int getIconResId(int index) {
// return ICONS[index % ICONS.length];
// }
public void setCount(int count) {
// if (count > 0 && count <= 10) {
// mCount = count;
// notifyDataSetChanged();
// }
}
}
我的 fragment 类之一如下
public class FragmentationNomineeDetails extends Fragment {
private String nominNameStr;
private String nomindobStr;
private String nominageStr;
private String nominrelationshipStr;
private EditText nomini_name_et;
private TextView nomi_dob_tv;
private EditText nomi_age_et;
private EditText nomi_relationship_et;
private View layout;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
layout = inflater.inflate(R.layout.fragment_nomination_details,
container, false);
Button save = (Button) layout.findViewById(R.id.save);
nomini_name_et = (EditText) layout
.findViewById(R.id.nomini_name_et);
nomi_dob_tv = (TextView) layout.findViewById(R.id.nomi_dob_tv);
nomi_age_et = (EditText) layout.findViewById(R.id.nomi_age_et);
nomi_relationship_et = (EditText) layout.findViewById(R.id.nomi_relationship_et);
setlistener();
return layout;
}
@Override
public void onDestroyView() {
// TODO Auto-generated method stub
super.onDestroyView();
layout=null;
}
}
它正在工作。我可以滑动到任何 fragment ，但滑动 4 或 5 次后就会出现 stackoverflow 错误。 下面是我的 logcat。

最佳答案
更换一下试试
layout = inflater.inflate(R.layout.fragment_nomination_details,
container, false);
与
layout = inflater.inflate(R.layout.fragment_nomination_details,
null, false);
