Use the Internationalizations Views module, which extends the i18n module with multilingual support for views.
Also, to make view results correspond to the language switcher, add a filter for Content Translation: User's Current Language, which is the language that an authenticated user has set in the user settings (it is NOT the same as the current browser language or the site language).
If no option for the User's Current Language is available in the filter criteria form, then verify your configuration at Configuration -> Languages -> detection and selection: The order should be URL, Default, User and not something like Default, URL, User (as mentioned also in https://www.drupal.org/node/1701854#comment-6279474).
The above may turn out to NOT be the complete answer. Since you use the Entity Translation module, this option isn't there if you use it in 'entity' mode: if only some fields of the node are translatable the option is there but a bit more difficult to find. If you have the 'Body' of your nodes set to translatable entity then the option is "Body language" to be set to Current User Language.
Note: The Internationalizations Views module only has a DEV version for D7, but right now there are over 31K users using this version. Therefor I think "DEV" is not a valid release qualifier for that version anymore, because +31K users can't be wrong, right?
