在我的应用程序中，如果用户没有打开位置，我会通过对话框提示，然后尝试通过覆盖活动结果来返回该结果（可能不正确）。
这是一个片段，所以不确定如何改变：
这就是我将其称为startResolutionForResult的对话框：
public void checkDeviceLocationIsOn()
{
System.out.println("Test running setting request" );
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_LOW_POWER);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
builder.setAlwaysShow(true); //this is the key ingredient
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
final LocationSettingsStates state = result.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied.
System.out.println("Test setting all fine starting location request" );
getLocation();
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(getActivity(), LOCATION_SETTINGS_REQUEST_CODE);
System.out.println("Test setting not met starting dialog to prompt user" );
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way to fix the
// settings so we won't show the dialog.
break;
}
}
});
}
然后我尝试在下面得到这样的结果（这永远不会被调用）：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
// Check for the integer request code originally supplied to startResolutionForResult().
case LOCATION_SETTINGS_REQUEST_CODE:
switch (resultCode) {
case Activity.RESULT_OK:
System.out.println("test user has turned the gps back on");
getLocation();
break;
case Activity.RESULT_CANCELED:
System.out.println("test user has denied the gps to be turned on");
Toast.makeText(getActivity(), "Location is required to order stations", Toast.LENGTH_SHORT).show();
break;
}
break;
}
}

使用startIntentSenderForResult(status.getResolution().getIntentSender(), REQUEST_CODE_LOCATION_SETTING, null, 0, 0, 0, null);
而不是startResolutionForResult（）

要开始解析片段中的结果，您应该使用新的 API
首先，创建ActivityResultLanucher
private val resolutionForResult =
registerForActivityResult(ActivityResultContracts.StartIntentSenderForResult()) { activityResult ->
if (activityResult.resultCode == RESULT_OK)
//startLocationUpdates() or do whatever you want
else {
showMessage("we can't determine your location")
}
}
然后像这样使用它
val intentSenderRequest = IntentSenderRequest.Builder(exception.resolution).build()
resolutionForResult.launch(intentSenderRequest)

也许一个简单的解决方案是使用两个活动，并通过使用清单上的任何对话框主题来显示一个对话框
<activity
android:name=".LocationDialogActivity"
android:theme="@style/DialogStyle"></activity>
他们只是使用onActivityResult，因为你总是使用它。
DialogActivity
private void setLocation() {
Intent intentResult = new Intent();
intentResult.putExtra("latitude", "valueLat");
intentResult.putExtra("longitude", "valueLon");
setResult(RESULT_OK, intentResult);
finish();
}
MainActivity
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
/*Take your data*/
latitude = data.getExtras().getString("latitude");
longitude = data.getExtras().getString("longitude");
}
}

执行此方法...
MainActivity中的
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
final int REQUEST_CHECK_SETTINGS = 100;//check GPS setting
Log.d("onActivityResult()", Integer.toString(resultCode));
//final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
switch (requestCode)
{
case REQUEST_CHECK_SETTINGS:
switch (resultCode)
{
case Activity.RESULT_OK:
{
// All required changes were successfully made
Toast.makeText(this, "Location enabled by user!", Toast.LENGTH_LONG).show();
ContactFragment.isGPSEnabled=true;
ContactFragment.click();
break;
}
case Activity.RESULT_CANCELED:
{
// The user was asked to change settings, but chose not to
Toast.makeText(this, "Location not enabled, user cancelled.", Toast.LENGTH_LONG).show();
ContactFragment.isGPSEnabled=false;
break;
}
default:
{
break;
}
}
break;
}
}
在ContactFragment内部
@Override
public void onConnected(@Nullable Bundle bundle) {
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationRequest.setInterval(30 * 1000);
mLocationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true);
result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
result.setResultCallback(this);
}
@Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
//final LocationSettingsStates state = result.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can initialize location
// requests here.
//...
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(
getActivity(),
REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way to fix the
// settings so we won't show the dialog.
//...
break;
}
}
