How To Check Edit Text Is Empty

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

Solution 1:

you can try this :

if ((f.trim().equals('') || (f1.trim().equals('') ||........) { 

    // Error , one or more editText are empty

}
else
{
    // all editText are not empty 
}

Solution 2:

// Edit

I think you have it the wrong way, where your if statment is when every is filled in, your else when one of the fields is empty

---- previous answer ----

You can do it like this.

if(editText.getText().toString().length() > 0) {
     // editText is not empty
} 

if(editText.getText().toString().length() == 0) {
     // editText is empty
}

Solution 3:

Mats and Houcine answers are valid but you can even do shorter using isEmpty():

if(editText.getText().toString().isEmpty()) {
     // editText is empty
} else {
     // editText is not empty
}
