Question

我想在google地图上做一个标记，latlng是已知的，如何获取地址并在google地图中显示，我需要一个桌面应用程序（RCP），我已经执行了eclipse，我可以得到满意的结果。 `import java.io.File;

import org.eclipse.swt.SWT;
import org.eclipse.swt.browser.Browser;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class BrowserTest {

    public static void main(String[] args) {
    File f = new File("F:/Javawork/EclipseWork/mapother/map7.html");
    final Display display = Display.getDefault();
    final Shell shell = new Shell();
    //shell.setSize(327, 253);
    shell.setSize(981, 759);
    // 
    shell.setLayout(new FillLayout());
    Browser browser = new Browser(shell, SWT.NONE);
    browser.setUrl(f.toURI().toString());

    //browser.execute("var arr = new Array(31.28794,121.475372)");
    //browser.execute("var lat = parseFloat(arr[0]);\r\n"
    //              + "var lng = parseFloat(arr[1]);\r\n"
    //              + "var latlng = new google.maps.LatLng(lat, lng);\r\n");
    //browser.execute("alert('latlng' + latlng);");
    browser.execute("geocoder.geocode({'latLng': 31.28794,121.475372}, function(results, status){"
            + "infowindow.setContent(results[1].formatted_address);"
            + "infowindow.open(map, new google.maps.Marker({position: latlng,map: map}));"
            + "})");
    //browser.execute("{};");
    browser.execute("alert('lat' + lat + ';'+'lng' + lng);");

    //browser.execute(" map.setCenter(results[0].geometry.location);");
    //browser.execute("var marker = new google.maps.Marker({map: map, position: results[0].geometry.location });");
    // -----------------END------------------------
    shell.layout();
    shell.open();
    while (!shell.isDisposed()) { 
        if (!display.readAndDispatch())
            display.sleep();
    }
    display.dispose();
}

}
