if(edittext.getText().toString().split(" ")[0].equals("YOUR_STRING")) {
//DO THE TASK
}

With null/ empty check you can

if (! TextUtils.isEmpty(editText.getText())) {
            if ("LOOKING_STRING".equals(editText.getText().toString().split(" ")[0])) {
                //DO THE TASK HERE
            }
        }

String s = edittext.getText().toString();

if (s.substring(0, s.indexOf(" ")).equalsIgnoreCase("a")) {
    // do stuff
}

You can also use a faster way for your condition as follows:

if (edittext.getText().toString().trim().startsWith("a")) {
      // here your code when it starts with "a"   
} else {
     // here your code when it is not
}

You can use substring method.

    String dummy = edittext.getText();

    if(dummy.substring(0,1).equalsIgnoreCase("a")){
    //your code goes here

    }
