Question

我正在尝试在RecyclerView中显示一个包含图像和文本的列表。该类扩展了片段类，因为它是Tab的一部分。这是我的代码。

这是我的片段类。

myModalObj

这是带有getter和setter方法的模型类。

public class Recharges extends Fragment {

public RecyclerView recyclerView;
private List<GetRecharge> rechargeList = new ArrayList<>();
public RecyclerView.LayoutManager layoutManager;
public Adapter adapter;
ImageView image1, image2;



@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    Toolbar myToolbar = (Toolbar) getActivity().findViewById(R.id.my_toolbar);
    ((AppCompatActivity) getActivity()).setSupportActionBar(myToolbar);

    View rootView = inflater.inflate(R.layout.rechargelist, container, false);


    image1 = new ImageView(getContext());
    image1.setImageResource(R.drawable.account);


    recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerview1);
    recyclerView.setHasFixedSize(true);

    adapter = (Adapter) new Adapterrecharge(rechargeList);
    LinearLayoutManager llm = new LinearLayoutManager(getActivity());
    recyclerView.setLayoutManager(llm);

    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.setAdapter((RecyclerView.Adapter) adapter);

    prepareRechargeData();

    return rootView;

}

private void prepareRechargeData() {
    GetRecharge recharge = new GetRecharge("Mad Max: Fury Road", image1 );
    rechargeList.add(recharge);

    //recharge = new GetRecharge("Inside Out", "Animation, Kids & Family", "2015");
    //rechargeList.add(recharge);


    adapter.notifyDataSetChanged();


}

这是适配器类

public class GetRecharge {
private String title;
ImageView image;

public GetRecharge() {
}

public GetRecharge(String title, ImageView image) {
    this.title = title;
    this.image = image;
}

public String getTitle() {
    return title;
}

public void setTitle(String name) {
    this.title = name;
}

public ImageView getImage() {
    return image;
}

public void setImage(ImageView image) {
    this.image = image;
}


}

Answer 1

下面：

image1 = new ImageView(getContext());

仅创建ImageView对象而不为View设置LayoutParams。这样做：

image1 = new ImageView(getContext());
image1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, 
LayoutParams.WRAP_CONTENT));
image1.setImageResource(R.drawable.account);

另一种或简单的方法就是将R.drawable.account int id传递给GetRecharge并调用： holder.image.setImageResource(recharge.getImage());

如何在可绘制文件夹中的片段中的recyclerview中设置图像？
