@igorepst I came up with a quick solution to the blue cursor problem. I added a 500 ms wait operation (probably it could be less time) in line 217 and It seems to work. Could you give it a try? :) |

Hi @neutronstein. I am going to check it out as soon as possible. |

@felHR85 nice implementation. I just tried it out and noticed something, your initEditText method traverse your layout for editTexts, but it will miss dynamical added EditTexts after the initialization, or am i missing something ? also, i can't see where editTextList is actually used. And also thank you, you saved me a lot of work ;) |

Any clue why the keyboardcallback isn't working anymore once you rotate your screen? |

@neutronstein I finally managed to find what was happening in landscape mode. Basically, for some reason, currentBottomLocation keeps the same value of layoutBottom, so it quits from the loop in line 211 when it shouldn't. The easiest way to solve it is adding this option for each EditText in your layout: With that option keyboard does not fill the whole screen (as by default does ) but it works as usual. |

I tried using this code and i am setting the some imageview to visible , invisible in show hide callbacks. But it throws the exception "Only the original thread that created a view hierarchy can touch its views" . It seems from the code that you are creating a new thread and its not returning on main thread. Can you please check that and update |

This code not working at all. When I open up the soft keyboard then the code running down the onSoftKeyboardShow and then running down the onSoftKeyboardHide too. Tested on Android 5.1 Nexus 6. When I just close the soft kb. nothing happening.. |

Hi @lacasrac. Is your app running on landscape? |

Same as @lacasrac, it calls onSoftKeyboardShow then onSoftKeyboardHide but it does not hide the keyboard oO (on portrait and landscape) |

Hi, I have a weird issue where if i change some views visibly to GONE in onSoftKeyboardShow - than onSoftKyboardHide gets called (without keyboard being closed). any idea how can I use this to hide some views while keyboard is shown, and than show them when keyboard is hidden? |

Hi @eladhackim and others. I've abandoned this for some months but it is time to check all the issues. I will spend time this weekend and probably I will release a little example app with the code in github. |

Thank you very much for this solution. Is there any way to detect when the keyboard finished opening? I'm trying to smooth scrool to the last position of a reclycler view when the keyboard opens. Sometimes the scroll is done before the keyboard is fully opened. Since the Recyclerview gets resized by keyboard opening, it doesn't show the last item anymore :( |

Sorry! @EtienneHanser and many others with troubles with this snippet but I got too busy at this moment. This is really a hack (in both good and bad ways) so in some cases probably won't work because I soon realized that there are many differences in the way Android draws (for example the EditText displays the keyboard and the redraw is different than other cases, that was corrected). I didn't try with the RecyclerView yet (I just started to use them recently!) but it would be nice if you can send me a little example to give it a look. Maybe it is not difficult and can be done quickly! Of course, I encouraged everybody to add, modify and submit changes (gist doesn't have pull requests but you can send me an email with your versions and I will check it out). Thank you guys. Felipe |

This does not work properly with fragments. Keyboard show method is being called but the Hide method is not being called. For Activity it is working fine. |

Hi, thank you for this great code. However, could you describe, please, what is the purpose of editText.setCursorVisible(false); and why it was uncommented on 7 Oct?
