I am developing a application in which if i click a button it woul d check that all the edit text are empty or something written and providing similar alert box for that message.i had made a method.... How to find that edittext is full empty or contain any values inside it programmatically on button click. empty data insertion is one of the most big problems in online registration word because sometimes application user just to check our app is working properly or not they trying to send empty data to server but after putting empty condition on edittext app user is compulsory bound to enter. Your edittext's id is edittext1. so we can check edittext is empty or not with following code. (input.gettext().tostring().equals("")) we have given two condition empty and not empty using if else condition and the message is shown using toast..
Java - some layouts don't draw when the keyboard goes down
The more you tell the ui about the underlying data format the more the ui can help you validate user input. the ui will/may present the user a number input pad vs the full char input method.. If function return false means edittext is not empty and return true means edittext is empty for more info see this best link check if edittext is empty. get document on some condition in elastic search java api. I have 5 edittexts in android for users to input. i would like to know if i could have a method for checking all the 5 edittexts if they are null. is there any way to do this??.
