单击按钮时请求GPS位置

Question

我想提示用户请求GPS位置，然后获取位置（lat，lng）。

像这样： http://4.bp.blogspot.com/-CC8P9RN7_pk/VPTwYyjt8kI/AAAAAAAABWw/A5cjqZc39hQ/s1600/Location%2BSettings%2BDialog.png

Answer 1

我相信Google提供的位置感知培训涵盖了这一点，here。

特别是：

• the prompt
• obtaining the location (current and updates)

Answer 2

GPS启用提示代码：

public boolean canGetLocation() {
        return this.canGetLocation;
    }

    public void showSettingsAlert(){
        AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);

        alertDialog.setTitle("GPS is settings");

        alertDialog.setMessage("GPS is not enabled. Do you want to go to settings menu?");
        alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog,int which) {
                Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                mContext.startActivity(intent);
            }
        });
        alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
            }
        });
        alertDialog.show();
    }

您想要的当前位置（如lat，long或google地图）。
