在android中查看数据库

是关于预约的

我有5页链接一个接一个

在第4页中，数据根据用户在第3页中给出的数据进入数据库

在用户确认约会日期和时间之前，用户应在列表视图表单中查看数据库

这就是我写的代码。你能帮我纠正一下吗

我的基本适配器类：

public class viewlistadapter extends BaseAdapter 
{
SQLiteDatabase sdb;

private Context viewcontext;
ArrayList v1=new ArrayList();
ArrayList v2=new ArrayList();
ArrayList v3=new ArrayList();
ArrayList v4=new ArrayList();
ArrayList v5=new ArrayList();

int length;

public viewlistadapter(viewlist vl, ArrayList value12, ArrayList value22, ArrayList     value32, ArrayList value42, ArrayList value52)
{
    viewcontext=vl;
    v1=value12;
    v2=value22;
    v3=value32;
    v4=value42;
    v5=value52;
    length=v1.size();

}
public viewlistadapter(viewlist vl, String value12, String value22,
        String value32, String value42, String value52) 
    {
    // TODO Auto-generated constructor stub
}
public int getCount() 
    {
    // TODO Auto-generated method stub
    return length;
}

public Object getItem(int arg0) 
    {
    // TODO Auto-generated method stub
    return null;
}

public long getItemId(int position) 
    {
    // TODO Auto-generated method stub
    return 0;
}

public View getView(int position, View convertView, ViewGroup parent) 
    {
    // TODO Auto-generated method stub

    LinearLayout l=new LinearLayout(viewcontext);

    TextView tv1=new TextView(viewcontext);
    TextView tv2=new TextView(viewcontext);
    TextView tv3=new TextView(viewcontext);
    TextView tv4=new TextView(viewcontext);
    TextView tv5=new TextView(viewcontext);

    tv1.setText((String) v1.get(position));
    tv2.setText((String) v2.get(position));
    tv3.setText((String) v3.get(position));
    tv4.setText((String) v4.get(position));
    tv5.setText((String) v5.get(position));

    l.addView(tv1);
    l.addView(tv2);
    l.addView(tv3);
    l.addView(tv4);
    l.addView(tv5);

    return l;

}
}

活动课是

首先我们可以试试这个。程序“sqlite浏览器”可以显示数据库中的数据。你可以在这里下载(http://sourceforge.net/projects/sqlitebrowser/). 它很容易使用

二,。。 打开cmd转到程序工具

D:\Android Setup\android-sdk_r17-windows\android-sdk-windows\platform-tools>adb
shell
# cd data
cd data
# cd data
cd data
# cd com.maid.testnews(package name )
cd com.maid.testnews
# cd databases
cd databases
# sqlite3 Maidnews(Database name )
sqlite3 Maidnews
SQLite version 3.6.22
Enter ".help" for instructions
Enter SQL statements terminated with a ";"

sqlite> select * from maidtitle;(table name )

看到你的结果了

三,。

在Eclipse中，查看文件资源管理器选项卡（控制台选项卡附近）。或者查看菜单“窗口->显示视图->其他…->文件资源管理器”。应该运行模拟器。在文件资源管理器窗口中，转到文件夹“data/data/[your_package_name]/databases/”。在那里你可以找到你的数据库。您可以将其导出到您的计算机。在窗口的右上角有一个按钮“从设备中拉出文件”。选择数据库，单击该按钮并在计算机上保存数据库。

问题非常广泛。在发布问题之前，你应该尽可能缩小范围。当然，下次我会考虑c，fiddler…你能帮我解决这个问题吗…请…thnk u maid786我认为我的问题不正确，或者你不明白我想要什么…我想在工作应用程序中以listview格式查看数据库中的数据。。。。
