android - Toast.makeText() 显示错误

Question

我正在尝试使用 gps 查找位置，但以下代码 fragment 创建问题。错误显示为

The method makeText(Context, CharSequence, int) in the type Toast is not applicable
for the arguments (GeocodingMainActivity, String, int)

..........

private class MyLocationListener implements LocationListener {

 public void onLocationChanged(Location location) {
     String format = String.format( "New Location \n Longitude: %1$s \n Latitude: %2$s", location.getLongitude(), location.getLatitude());
    String message = format;
     Toast.makeText(GeocodingMainActivity.this, message, Toast.LENGTH_LONG).show();
 }

 public void onStatusChanged(String s, int i, Bundle b) 
 {Toast.makeText(GeocodingMainActivity.this, "Provider status changed",Toast.LENGTH_LONG).show();
 }

 public void onProviderDisabled(String s) {
     Toast.makeText(GeocodingMainActivity.this,"Provider disabled by the user. GPS turned off",Toast.LENGTH_LONG).show();
 }

 public void onProviderEnabled(String s) {
     Toast.makeText(GeocodingMainActivity.this,"Provider enabled by the user. GPS turned on",Toast.LENGTH_LONG).show();
 }

试试这个...

Toast.makeText(getApplicationContext(), "message", Toast.LENGTH_LONG).show();
