我在通過短信發送位置坐標時遇到困難。我無法正確構圖發送的短信。這是我的頂級代碼：private static final int REQUEST_CODE = 1000;FusedLocationProviderClient fusedLocationProviderClient;LocationRequest locationRequest;LocationCallback locationCallback;@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); switch (requestCode) { case REQUEST_CODE: { if(grantResults.length > 0) { if(grantResults[0] == PackageManager.PERMISSION_GRANTED) { } else if(grantResults[0] == PackageManager.PERMISSION_DENIED) { } } } }}在我的“創建”中，雙符號讀取了意外的令牌錯誤。我也認為我需要在那里添加一個私人空白，但不知道哪種與發送短信相對應。if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE); } else { buildLocationRequest(); buildLocationCallback(); fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this); { if (ActivityCompat.checkSelfPermission(FullscreenActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) && ActivityCompat.checkSelfPermission(FullscreenActivity.this, Manifest.permission.ACCESS_COARSE_LOCATION); ActivityCompat.requestPermissions(FullscreenActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE); return; } fusedLocationProviderClient.requestLocationUpdates(locationRequest, locationCallback, Looper.myLooper()); }在 onCreate 部分之后，我遇到了最多困難的地方，特別是位置當前位置字符串中的位置方法，該字符串說參數從未使用過，并且我也得到了一個錯誤與 getLongitude 關閉。它包含一個帶有分號的錯誤，我在那里添加的任何內容都不起作用，例如a ）。我不知道我是否正確執行此位置/短信類。

在構建后添加 getLastLocation（） 方法位置回調
private void getLastLocation() {
try {
fusedLocationProviderClient.getLastLocation()
.addOnCompleteListener(new OnCompleteListener<Location>() {
@Override
public void onComplete(@NonNull Task<Location> task) {
if (task.isSuccessful() && task.getResult() != null) {
mLocation = task.getResult();
location("MY_PHONE_NUMBER", task.getResult());
} else {
Log.w(TAG, "Failed to get location.");
}
}
});
} catch (SecurityException unlikely) {
Log.e(TAG, "Lost location permission." + unlikely);
}
}
更新您的位置信息方法
private void location(String phoneNumber, Location currentLocation) {
try {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNumber, null, "maps.google.com?q=" + currentLocation.getLatitude() + "," + currentLocation.getLongitude(), null, null);
Toast.makeText(getApplicationContext(), "SMS Sent!",
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again later!",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
