Android: Check If Edittext Is Empty When Inputtype Is Set On Number/phone

I have an EditText in android for users to input their AGE. It is set an inputType=phone. I would like to know if there is a way to check if this EditText is null. I've already l

Solution 1:

You can check using the TextUtils class like

TextUtils.isEmpty(ed_text);

or you can check like this:

EditTexted= (EditText) findViewById(R.id.age);

Stringed_text= ed.getText().toString().trim();

if(ed_text.isEmpty() || ed_text.length() == 0 || ed_text.equals("") || ed_text == null)
{
    //EditText is empty
}
else
{
    //EditText is not empty
}

Solution 2:

First Method

Use TextUtil library

if(TextUtils.isEmpty(editText.getText().toString()) 
{
    Toast.makeText(this, "plz enter your name ", Toast.LENGTH_SHORT).show();
    return;
}

Second Method

privatebooleanisEmpty(EditText etText) 
{
        return etText.getText().toString().trim().length() == 0;
}

Solution 3:

Add Kotlin getter functions

val EditText.empty get() = text.isEmpty() // it == ""// and/or
val EditText.blank get() = text.isBlank() // it.trim() == ""

With these, you can just use if (edittext.empty) ... or if (edittext.blank) ...

If you don't want to extend this functionality, the original Kotlin is:

edittext.text.isBlank()
// or
edittext.text.isEmpty()

Solution 4:

EditText textAge;
textAge = (EditText)findViewByID(R.id.age);
if (TextUtils.isEmpty(textAge))
{
Toast.makeText(this, "Age Edit text is Empty", Toast.LENGTH_SHORT).show();
//or type here the code you want
}

Solution 5:

I use this method for same works:

publicbooleancheckIsNull(EditText... editTexts){
for (EditTexteditText: editTexts){
  if(editText.getText().length() == 0){
    returntrue;
  }
}
returnfalse;
}
