登录页面后我的订购应用程序将转到 Scanner、List 和 Order。在我点击订单后进入目录，它可以在 eclipse 虚拟设备上运行，但不能在移动设备上运行。其他页面没问题

这是 CatalogActivity.java

package com.example.barcode;

import java.util.List;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.Button;
import android.widget.ListView;

public class CatalogActivity extends Activity {

 private List<Product> mProductList;
 Button button;


 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.catalog);

  // Obtain a reference to the product catalog
  mProductList = ShoppingCartHelper.getCatalog(getResources());

  // Create the list
  ListView listViewCatalog = (ListView) findViewById(R.id.ListViewCatalog);
  listViewCatalog.setAdapter(new ProductAdapter(mProductList, getLayoutInflater(), false));

 listViewCatalog.setOnItemClickListener(new OnItemClickListener() {

  @Override
  public void onItemClick(AdapterView<?> parent, View view, int position,
    long id) {
   Intent productDetailsIntent = new         Intent(getBaseContext(),ProductDetailsActivity.class);
   productDetailsIntent.putExtra(ShoppingCartHelper.PRODUCT_INDEX, position);
  startActivity(productDetailsIntent);
}
});

Button viewShoppingCart = (Button) findViewById(R.id.ButtonViewCart);
viewShoppingCart.setOnClickListener(new OnClickListener() {

 @Override
 public void onClick(View v) {
  Intent viewShoppingCartIntent = new Intent(getBaseContext(), ShoppingCartActivity.class);
  startActivity(viewShoppingCartIntent);
 }
});

}

}

这是电话的目录

您必须找到长度为零的字符串。那是发生错误时生成的完整日志吗？读取文件时会发生 IO 异常，但是在发布的代码中没有文件操作。您的这部分代码似乎也没有错误。
