如何在点击查看寻呼机时打开详细信息片段?

Question

我，在我的项目中实现了view-pager。现在我想要当我单击特定的视图页面时，它将打开一个新的细节片段。根据该图像滑块信息可用的地方。

这是我的代码：

适配器代码：

public class SliderImageAdapter extends SliderViewAdapter<SliderImageAdapter.SliderAdapterVH>{
public List<Banner> bannerList;
public Context context;
public SliderImageAdapter(Context context, List<Banner> bannerList) {
this.bannerList = bannerList;
this.context = context;
}
@Override
public SliderAdapterVH onCreateViewHolder(ViewGroup parent) {
View inflate = LayoutInflater.from(parent.getContext()).inflate(R.layout.image_slider_myshop, parent, false);
return new SliderAdapterVH(inflate);
}
@Override
public void onBindViewHolder(final SliderAdapterVH viewHolder, final int position) {
Glide.with(viewHolder.itemView)
.load(bannerList.get(position).getmSliderImage())
.fitCenter()
.into(viewHolder.imageViewBackground);
}
@Override
public int getCount() {
return bannerList.size();
}
public int getItemPosition (Object object) {
return POSITION_NONE;
}
class SliderAdapterVH extends SliderViewAdapter.ViewHolder {
View itemView;
ImageView imageViewBackground;
ImageView imageGifContainer;
public SliderAdapterVH(View itemView) {
super(itemView);
imageViewBackground = itemView.findViewById(R.id.iv_auto_image_slider);
imageGifContainer = itemView.findViewById(R.id.iv_gif_container);
this.itemView = itemView;
}
}
} 

主页片段代码：

private SliderImageAdapter sliderImageAdapter;
private List<Banner> bannerList;
sliderMyshop = view.findViewById(R.id.imageSlider);
sliderMyshop.setSliderAdapter(sliderImageAdapter);
sliderMyshop.setIndicatorAnimation(IndicatorAnimations.WORM); //set indicator animation by using SliderLayout.IndicatorAnimations. :WORM or THIN_WORM or COLOR or DROP or FILL or NONE or SCALE or SCALE_DOWN or SLIDE and SWAP!!
sliderMyshop.setSliderTransformAnimation(SliderAnimations.SIMPLETRANSFORMATION);
sliderMyshop.setIndicatorSelectedColor(Color.WHITE);
sliderMyshop.setIndicatorUnselectedColor(Color.GRAY);
sliderMyshop.startAutoCycle();
mFirestore.collection("Banner").orderBy("mSliderImage", Query.Direction.DESCENDING).addSnapshotListener(new EventListener<QuerySnapshot>() {
@Override
public void onEvent(@javax.annotation.Nullable QuerySnapshot documentSnapshots, @javax.annotation.Nullable FirebaseFirestoreException e) {
if (e != null) {
Log.d(TAG, "Error : " + e.getMessage());
}
assert documentSnapshots != null;
for (DocumentChange doc : documentSnapshots.getDocumentChanges()) {
if (doc.getType() == DocumentChange.Type.ADDED) {
String doc_id = doc.getDocument().getId();
Banner banner = doc.getDocument().toObject(Banner.class).withDocId(doc_id);
bannerList.add(doc.getNewIndex(), banner);
sliderImageAdapter.notifyDataSetChanged();
} else if (doc.getType() == DocumentChange.Type.MODIFIED) {
String docID = doc.getDocument().getId();
Banner changedModel = doc.getDocument().toObject(Banner.class).withDocId(docID);
if (doc.getOldIndex() == doc.getNewIndex()) {
// Item changed but remained in same position
bannerList.set(doc.getOldIndex(), changedModel);
} else {
// Item changed and changed position
bannerList.remove(doc.getOldIndex());
bannerList.add(doc.getNewIndex(), changedModel);
}
} else if (doc.getType() == DocumentChange.Type.REMOVED) {
// remove
bannerList.remove(doc.getOldIndex());
}
sliderImageAdapter.notifyDataSetChanged();
}
}
});

现在，我想在单击特定图像时打开另一个片段。根据位置。请指导我如何做到这一点。

您需要在方法onBindViewHolderimageview上添加Onclicklistener：

viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
}
});

然后，您需要分离Activity并在onclick方法中调用该活动，如下所示：

context.startActivity(new Intent(context,DetailActivity.class)) 

您还可以向此DetailActivity添加片段。
