我创建了一个包含ViewPager的ScrollView,但是ViewPager的高度没有增加。当ViewPager内部内容太多时,它会被“挤压”并且表格空间缩小。
我搜索了解决方案并发现问题在于使用了wrap_content
,因为ViewPager加载时没有内容。因此, ViewPager保持屏幕高度。我找到的解决方案不适用于FragmentPagerAdapter
,因此我编辑了这个问题。
请指引我正确的方向。
问候,Christophe VD.
FragmentPagerAdapter代码:
import android.content.Context;
import android.graphics.pdf.PdfDocument;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class film_tabs_adapter extends FragmentPagerAdapter {
private final String[] TITLES = { "Info", "Comment", "Cast", "Muziek"};
String[] Film_Data;
public film_tabs_adapter(FragmentManager fm, String[] Film_Data_in) {
super(fm);
Film_Data = Film_Data_in;
}
@Override
public CharSequence getPageTitle(int position) {
return TITLES[position];
}
@Override
public int getCount() {
return 4;
}
@Override
public Fragment getItem(int position) {
Fragment fragment =null;
Bundle bundle = new Bundle();
bundle.putStringArray("Film_Data", Film_Data);
switch(position) {
case 0:
//return new film_info();
fragment = new film_info();
fragment.setArguments(bundle);
return fragment;
case 1:
return new film_coment();
case 2:
return new film_cast();
case 3:
return new film_sound();
default:
return new film_info();
}
}
}
以及Fragment的类别:
import android.content.Context;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class film_info extends Fragment {
TextView label_locatie;
...
TableLayout TimeTabel;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_film_info, container, false); // layout (activity_film_info) openen
Context context = inflater.getContext();
DatabaseVerwerker DB = new DatabaseVerwerker(context);
String[] Film_Data = getArguments().getStringArray("Film_Data");
...
return view;
}
}
