Question

我正在尝试启用/禁用GPS。我试过这段代码 - ：

.edmx

它提供安全权限错误。我也尝试打开设置 - ：

 //Enable GPS
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
context.sendBroadcast(intent);
//Disable GPS
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", false);
context.sendBroadcast(intent);

它不适用于每台设备。是他们的任何解决方案来处理所有版本的android。

Answer 1

这是deprecated。您无法以编程方式打开/关闭位置。我建议您使用最新版本的GooglePlayService。使用PlayService，您可以随时查看是否启用了location。如果未启用，则AlertDialog启用它。即使不离开您的应用程序，您也可以启用GPS。如果未启用，则可以执行要执行的操作。您可以在此post

基本上，您的Activity应该实施ResultCallback<LocationSettingsResult>

如下所示注册PendingIntent，

PendingResult<LocationSettingsResult> result =
            LocationServices.SettingsApi.checkLocationSettings(
                    mGoogleApiClient,
                    mLocationSettingsRequest
            );
    result.setResultCallback(this);

现在你有一个onResult回调，你可以执行你想做的事情

@Override
public void onResult(LocationSettingsResult locationSettingsResult) {
    final Status status = locationSettingsResult.getStatus();
    switch (status.getStatusCode()) {
        case LocationSettingsStatusCodes.SUCCESS:
            Log.i(TAG, "All location settings are satisfied.");
            startLocationUpdates();
            break;
        case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
            Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to" +
                    "upgrade location settings ");
            try {
                // Show the dialog by calling startResolutionForResult(), and check the result
                // in onActivityResult().
                status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
            } catch (IntentSender.SendIntentException e) {
                Log.i(TAG, "PendingIntent unable to execute request.");
            }
            break;
        case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
            Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog " +
                    "not created.");
            break;
    }
}
