我在Dialogbox中加载viewpager，Viewpager包含不同的片段
下面是我的对话框代码
public void openFillUpInformationDialog(){
final Dialog dialog = new Dialog(MainActivity.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_dialog_filling_form);
_mViewPager = (ViewPager) dialog.findViewById(R.id.viewPager);
_adapter = new ViewPagerAdapter(getApplicationContext(),getSupportFragmentManager());
_mViewPager.setAdapter(_adapter);
_mViewPager.setCurrentItem(0);
dialog.show();
}
ViewPagerAdapter
public class ViewPagerAdapter extends FragmentPagerAdapter {
private Context _context;
public ViewPagerAdapter(Context context, FragmentManager fm) {
super(fm);
_context=context;
}
@Override
public Fragment getItem(int position) {
Fragment f = new Fragment();
switch(position){
case 0:
System.out.println("Form 1 will loaded");
f= LayoutOne.newInstance(_context);<------I am getting error over here
break;
case 1:
f= LayoutTwo.newInstance(_context);
break;
}
return f;
}
@Override
public int getCount() {
return 2;
}
}
LayoutOne.java是
public class LayoutOne extends Fragment {
public static Fragment newInstance(Context context) {
LayoutOne f = new LayoutOne();
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
ViewGroup root = (ViewGroup) inflater.inflate(R.layout.first_form, null);
return root;
}
}
我已经搜索了很多次，但仍然无法解决我的问题，请帮助我。
first_form.xml 的布局文件是
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
