当我使用该代码时它的工作,它给出街道名称, 脚本给我从LATITUDE值和我手动插入的LONGITUDE值的街道名称,

但如果我改变下面的代码

List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);

on cektempat();

部分
List<Address> addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);

我的代码不起作用,我被设置了权限,但代码仍然没有工作..

任何人都可以帮助我吗?

之前谢谢

这是logcat

您的位置似乎是null。请注意,该设备无法立即获取您的位置。

以下是有关它的大量信息 http://developer.android.com/guide/topics/location/strategies.html

答案 1 :(得分:0)

它的外观位置为空,然后在您的try catch广告代码段中添加NullPointerException以防止应用崩溃,因为该位置为null

try {
    List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);

    if(addresses != null) {
        Address returnedAddress = addresses.get(0);
        StringBuilder strReturnedAddress = new StringBuilder("Anda ada di ");
        for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
            strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
        }
        pesan = strReturnedAddress.toString();
        String message = pesan;
        sendMessage(message);
        startTextToSpeech2();

    } else{

        pesan = "Maaf saya tidak tahu anda dimana";
        String message = pesan;
        sendMessage(message);
        startTextToSpeech2();
    }
} catch (NullPointerException e) {
    pesan = "Maaf saya tidak tahu anda dimana";
    String message = pesan;
    sendMessage(message);
    startTextToSpeech2();
}
