Android editText.getText()

Question

What is wrong with the code:

String maintext = (String) main_text.getText().toString();

if(maintext =="10") {           
    ToneGenerator toneG = new ToneGenerator(AudioManager.STREAM_ALARM, 100);
    toneG.startTone(ToneGenerator.TONE_CDMA_ALERT_CALL_GUARD, 200);
}

The code is working without if statement but with the use of if and .getText().toString() is not working at all.

for string equality you must use `.equals()` instead of `==` so change `maintext =="10"` to `maintext.equals("10")` — Shayan Pourvatan, Oct 13 '15 at 10:40
As well you need not to convert maintext to String because getText() will always returns string value — Madhu, Oct 13 '15 at 10:41

@Madhu `getText()` return `Editable` object, so `.toString()` is need, — Shayan Pourvatan, Oct 13 '15 at 10:42
@shayanpourvatan yes i agree but (String) is no need when using getText().toString right — Madhu, Oct 13 '15 at 10:43

== tests object references, .equals() tests the string values.

use equals

if(maintext.equals("10"))

Finally

    if(maintext.equals("10"))
    {

        ToneGenerator toneG = new ToneGenerator(AudioManager.STREAM_ALARM, 100);
        toneG.startTone(ToneGenerator.TONE_CDMA_ALERT_CALL_GUARD, 200);


   }

How do I compare strings in Java?

You are incorrectly comparing two strings (maintext =="10"), change it to "10".equals(maintext)
