问题：
跳过启用GPS-OnActivityResult（）的LocationSettingsRequest对话框
薄哲
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true);
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 = result.getLocationSettingsStates();
switch (status.getStatusCode())
{
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can initialize location
// requests here.
...
Log.d("onResult", "SUCCESS");
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
Log.d("onResult", "RESOLUTION_REQUIRED");
try
{
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(OuterClass.this, REQUEST_LOCATION);
}
catch (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.
...
Log.d("onResult", "UNAVAILABLE");
break;
}
}
});
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
// This log is never called
Log.d("onActivityResult()", Integer.toString(resultCode));
final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
switch (requestCode)
{
case REQUEST_LOCATION:
switch (resultCode)
{
case Activity.RESULT_OK:
{
// All required changes were successfully made
break;
}
case Activity.RESULT_CANCELED:
{
// The user was asked to change settings, but chose not to
break;
}
default:
{
break;
}
}
break;
}
}
谢了！
编辑：我的应用程序结构的基本信息：
- 此代码包含在
片段的onresume()方法中，该方法实现GooglePiclient.ConnectionCallbacks、GooglePiclient.OnConnectionFailedListener和LocationListener以接收位置更新。在这里看到的示例。 - 在
onlocationchanged()中，片段将有一个自定义视图调用invalidate()并用更新的信息重新绘制自身。

在我们的应用程序中，我们希望集成android默认GPS对话框。当GPS关闭，我们在谷歌地图应用程序中按下我的位置按钮时，会出现相同的对话框。还附上了我想要集成的对话框的图像。 单击“否”选项将关闭对话框。 单击是选项将直接激活设备的GPS。 我们现有的实现是当GPS关闭时，我们将应用程序重定向到设备的默认位置设置屏幕，从那里他/她可以打开位置。 期待答案。提前感谢。

问题内容： 根据API文档，设备所有者应用可以通过以下调用来修改一些“安全设置”，尤其是LOCATION_MODE： 个人资料或设备所有者致电以更新Settings.Secure设置[…] 设备所有者可以另外更新以下设置：LOCATION_MODE 根据我的理解，LOCATION_MODE的值为int（分别为0（禁用位置），1（仅用于GPS），2（用于省电模式）和3（用于高精度）。 我的问题是参数
