装到手机上闪退的问题

Question

把错误的日志 贴上来看看 是哪里出的问题 不过我这里猜测一下 : 
你的模拟器的Android 版本是 2.x 的 , 手机 的Android 版本 是 4.x
在 4.x 中 与网络有关的操作必须放在线程里面进行, 而 2.x 可以直接在主线程中运行网络相关的操作; 
你的网络相关操作写在主线程了, 这个可能是你出现闪退的原因

Answer 1

如果是这样，程序应该怎么调整呢？我刚刚接触，你说的我对不上我感觉两种可能：第一种就是1楼说的线程；
你去搜索一下 android AsyncTask 或者android Thread的资料；    把与服务器交互的耗时操作放到线程中去；第二你可以查看一下你在AndroidManifest.xml中的权限配置；是否配置了INTERT权限 如果你在本地的有存储操作，是否有本地的存储操作权限
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>同时你可以用真机进行debug调试，看看问题到底在哪里！

Answer 2

public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        listView = (ListView) findViewById(R.id.listView);         new Thread(){  
         public void run(){  
         Message msg=new Message(); 
         msg.what=0x123; 
         msg.obj="abcd"; 
         myhandler.sendMessage(msg); 
         }  
        }.start();  
        //setListView();}
       
}
    final Handler myhandler=new Handler(){      public void handleMessage(Message msg){ 
     setListView();//通过webservice 与数据库交互
     } 
    };
private void setListView() { 
listView.setVisibility(View.VISIBLE);
list = dbUtil.getContainerInfo("货柜号");
adapter = new SimpleAdapter(
MianActivity.this, 
list, 
R.layout.adapter_item,  
new String[] { "LName"}, 
new int[] { R.id.txt_Cname}); listView.setAdapter(adapter);
}
 
改成这样，装到手机上还是闪退啊

Answer 3

看LogCat上面肯定把错误都输出了，不要被闪退纠结了，就是意思出错了！

囧 你开启一个线程发送消息 让handler来访问网络- -这不是和没开线程一样嘛  你应该在线程里面访问网络
new Thread(){  
         public void run(){                        list = dbUtil.getContainerInfo("货柜号");
         Message msg=new Message(); 
         msg.what=0; 
         myhandler.sendMessage(msg); 
         }  
        }.start();  然后再在handler里面设置listview
public void handleMessage(Message msg){ 
           switch(msg.what){
                case 0:
                       listView.setVisibility(View.VISIBLE);
        adapter = new SimpleAdapter(
                MianActivity.this, 
                list, 
                R.layout.adapter_item,  
                new String[] { "LName"}, 
                new int[] { R.id.txt_Cname});
                listView.setAdapter(adapter);
            }

我还以为是socket连接问题呢，话说我socket连接放到线程里也是出现这种问题
