Answer 1

您只需使用此操作启动活动：

startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));

我在对话框中使用它：

public static void displayPromptForEnablingGPS(final Activity activity)
    {

        final AlertDialog.Builder builder =  new AlertDialog.Builder(activity);
        final String action = Settings.ACTION_LOCATION_SOURCE_SETTINGS;
        final String message = "Do you want open GPS setting?";

        builder.setMessage(message)
            .setPositiveButton("OK",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface d, int id) {
                        activity.startActivity(new Intent(action));
                        d.dismiss();
                    }
            })
            .setNegativeButton("Cancel",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface d, int id) {
                        d.cancel();
                    }
            });
        builder.create().show();
    }
