Question

正如gif在滚动时可以看到的那样，在该活动中使用时，启动代码保留在该启动代码中，但是当置于片段中时会出现此问题。以下是文件任何建议或更改非常感谢。

Main2.java

public class Main2 extends AppCompatActivity {
String Tag="Main2";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       // setContentView(R.layout.activity_main);
        setContentView(R.layout.main2);


        Log.i(Tag, "onCreate: ");

        FragmentRecy fr=new FragmentRecy();



        FragmentTransaction transaction = 
        getSupportFragmentManager().beginTransaction();


        transaction.replace(R.id.fragment,fr);

        transaction.commit();



    }
}

ProductAdapter.java

public class ProductAdapter extends RecyclerView.Adapter<ProductAdapter.ProductHolder> {


    private  List<ProductModel> productslist;
    private int rowLayout;
    private Context context;

    @Override
    public ProductAdapter.ProductHolder onCreateViewHolder(@NonNull 
    ViewGroup parent, int viewType) {

        View view = 
    LayoutInflater.from(parent.getContext()).inflate(rowLayout, parent, 
    false);
        return new ProductHolder(view);
    }
    public ProductAdapter(List<ProductModel> productslist, int 
    rowLayout, Context context) {
        this.productslist = productslist;
        this.rowLayout = rowLayout;
        this.context = context;
    }

    @Override
    public void onBindViewHolder(@NonNull ProductAdapter.ProductHolder 
    holder, int position) {


        holder.productPrice.setText(productslist.get(position).getPrice()+" Per "+productslist.get(position).getQuantity() );
        holder.productText.setText(productslist.get(position).getName());


        Glide.with(context).load(productslist.get(position).getImageurl())
                .thumbnail(0.5f)

                .into(holder.productImage);


        final int pos=   position;

        holder.productLayout.setOnClickListener(new View.OnClickListener() {
            @Override

                Toast.makeText(context,"Clicked On"+productslist.get(pos).getName(),Toast.LENGTH_SHORT).show();
            }
        });
    }

    @Override
    public int getItemCount() {
        return productslist.size();
    }
    public interface ClickListener {
        void onClick(View view, int position);

        void onLongClick(View view, int position);
    }

Answer 1

您无法替换XML中包含的片段。它会将新片段放在“旧”片段的顶部。

有关详细信息，请参阅此问题：Android - fragment .replace() doesn't replace content - puts it on top
