我是开发Android应用程序的新手.我创建了自己的列表适配器,如下所示,我希望该列表可以检查.我该怎么做才能使我的列表包含每行的复选框？
public class listAvtivity extends ListActivity {
private LayoutInflater mInflater;
private Vector<RowData> data;
RowData rd;
static final String[] title = new String[] {
"*New*Apple iPad Wi-Fi (16GB)", "7 Touch Tablet -2GB Google Android",
"Apple iPad Wi-Fi (16GB) Rarely Used ","Apple iPad Wi-Fi (16GB) AppleCase" };
static final String[] detail = new String[] {
"1h 37m Shipping: $10.00","1h 39m Shipping: Free","58m 6s Shipping:$10.00","59m 30s Shipping: $10.95" };
//private Integer[] imgid = {
// R.drawable.bsfimg,R.drawable.bsfimg4,R.drawable.bsfimg2,
// R.drawable.bsfimg5
//};
@Override
public void onCreate(Bundle …我的应用程序中有一个谷歌地图组件,允许用户绘制多边形,线条和标记.现在我想实现一个按钮,允许用户导出他/她在地图中绘制的东西的kml文件.
有关这种方法的最佳方法的任何建议.
您的意见和贡献非常感谢
我试图运行alter table命令,我收到以下错误:
#1069 - 指定的密钥太多; 允许最多64个密钥
任何帮助将受到高度赞赏
下面的代码尝试要求用户上传 kml 文件，然后保存该文件，同时使用 google 地图 api v2 在 google 地图中显示 kml 数据。我可以成功获取 kml 文件并将其保存在特定目录中，但是，在用户单击 KML TEST 按钮后立即在谷歌地图上显示文件时遇到一些问题。错误是Uncaught ReferenceError: showKML 未定义
这是我使用的代码
