Question

我有一些CardView项目。我点击它时想要打开不同的活动。这是我的CardView适配器类的一部分

 @Override
public int getItemCount() {
    return productGroups.size();
}

public class ViewHolder extends RecyclerView.ViewHolder{
    private TextView txtGroupName;
    public ViewHolder(final View view) {
        super(view);

        txtGroupName = (TextView)view.findViewById(R.id.txtNameOfGroup);

        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                switch (getLayoutPosition()){
                    case 0: Intent intent = new Intent(view.getContext(),MyProductsActivity.class);
                        view.getContext().startActivity(intent);
                    case 1: Intent intent1 = new Intent(view.getContext(), VegetablesActivity.class);
                        view.getContext().startActivity(intent1);
                }

            }
        });
    }
}

我点击第一项（想要打开MyProductsActivity.class），但打开VegetablesActivity.class，只有当我点击手机上的后退按钮时才会打开MyProductsActivity.class

你忘了休息一下：

        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                switch (getLayoutPosition()){
                    case 0: Intent intent = new Intent(view.getContext(),MyProductsActivity.class);
                        view.getContext().startActivity(intent);
                    break;                                            //Here
                    case 1: Intent intent1 = new Intent(view.getContext(), VegetablesActivity.class);
                        view.getContext().startActivity(intent1);
                    break;                                            //Here
                }

            }
        });

cardview on click返回错误结果
