java TextView在FragmentStateAdapter中不显示全文
我想实现一个带有图像和文本的ViewPager,但是,有时文本显示不完全
<ImageView
安卓:id="@+id/presentation_art"
安卓:layout_width="match_parent"
安卓:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
安卓:id="@+id/presentation_title"
安卓:layout_width="wrap_content"
安卓:layout_height="wrap_content"
安卓:text="@string/presentation_title"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/presentation_art"/>
<TextView
安卓:id="@+id/presentation_content"
安卓:layout_width="wrap_content"
安卓:layout_height="wrap_content"
安卓:text="@string/presentation_content"
安卓:gravity="center"
安卓:maxWidth="256dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/presentation_title" />
但是,演示内容,有时有2行文本,有时有3行,但每种情况下只显示2行
public class PresentationPagesAdapter extends FragmentStateAdapter {
private static final int size = 3;
public PresentationPagesAdapter(Fragment fragment) {
super(fragment);
}
@NonNull
@Override
public Fragment createFragment(int position) {
return new PresentationPage(position);
}
@Override
public int getItemCount() {
return size;
}
public static class PresentationPage extends Fragment {
private ComponentPresentationBinding binding;
private final int n;
public PresentationPage(int n) {
this.n = n;
}
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
binding = ComponentPresentationBinding.inflate(inflater, container, false);
return binding.getRoot();
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Context context = getContext();
if (context != null) {
Presentation presentation = new Presentation(context, n);
binding.presentationContent.setText(presentation.getContent());
}
}
}
}
我已经在没有ViewBinding的情况下尝试过了,但是它抛出了相同的结果
我该怎么办
请帮助我:(
