使用LocationServices.getSettingsClient()禁用位置后addOnFailureListener不触发

• 核心原因是LocationSettingsRequest构建时未开启setAlwaysShow(true)配置，系统默认会缓存历史校验结果，只要用户此前同意过位置授权，后续即使手动关闭位置服务，checkLocationSettings也会直接返回成功回调，不会触发失败逻辑
• 你当前拆分OnSuccessListener和OnFailureListener的写法，无法在成功回调中直接获取状态码，实际上Task对象本身就支持直接获取Status，无需依赖异常返回

1. 修正LocationSettingsRequest构建逻辑 #

添加setAlwaysShow(true)强制每次校验都实时读取当前位置状态，不走缓存，同时明确位置请求优先级：

// 先确保LocationRequest配置正确
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); // 高精度模式会强制校验GPS状态
mLocationRequest.setInterval(10000);
mLocationRequest.setFastestInterval(5000);

LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
        .addLocationRequest(mLocationRequest)
        .setAlwaysShow(true); // 关键配置：禁用缓存，每次实时校验位置设置

2. 统一使用OnCompleteListener处理校验结果 #

不管成功失败都可以直接拿到Status，无需拆分两个回调，完美适配你需要的状态判断逻辑：

Task<LocationSettingsResponse> result = LocationServices.getSettingsClient(requireContext())
        .checkLocationSettings(builder.build());

result.addOnCompleteListener(requireActivity(), task -> {
    try {
        LocationSettingsResponse response = task.getResult(ApiException.class);
        // 位置设置满足要求，直接执行定位逻辑
        Log.i(TAG, "All location settings are satisfied.");
    } catch (ApiException e) {
        switch (e.getStatusCode()) {
            case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to upgrade location settings ");
                try {
                    // 唤起位置开启弹窗
                    ResolvableApiException resolvable = (ResolvableApiException) e;
                    // 若使用AndroidX建议替换为Activity Result API写法
                    resolvable.startResolutionForResult(requireActivity(), REQUEST_CHECK_SETTINGS);
                } catch (IntentSender.SendIntentException sendEx) {
                    // 忽略发送异常
                }
                break;
            case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog not created.");
                break;
        }
    }
});

3. 兜底场景补充 #

如果仍需要在成功回调中额外判断GPS状态，可以直接从返回结果中读取状态后补充校验：

LocationSettingsStates states = response.getLocationSettingsStates();
if (!states.isGpsUsable()) {
    // 手动触发一次位置设置校验，强制走失败回调唤起弹窗
    LocationServices.getSettingsClient(requireContext())
            .checkLocationSettings(builder.build())
            .addOnFailureListener(e -> {
                // 复用上述失败处理逻辑即可
            });
}
