Question

Hi I have an array that stores when radio buttons are checked so that when I load the radio settings again I can set the apporpriate one as checked.

My array is like this :

   |0          |1         |2
----------------------------------
0  |Option1    |data      |false
----------------------------------
1  |Option2    |data      |true
----------------------------------
2  |Option3    |data      |false
----------------------------------
3  |Option4    |data      |false

etc….

Now the index I am interested in is the true/false one as that tells me if that radio button should be checked.

I read these values from a database into the array. That’s all working fine and the data is in the array correctly.

For some reason when I do a comparison it does not match it up with what I can see is correct.

This is what I am doing in a loop…

String checked = myarray[i][2];

// This correctly outputs 'false', 'true', 'false' and 'false' as per the array above.            
Toast.makeText(DatabaseTestActivity.this, checked, Toast.LENGTH_LONG).show();

// Now when it gets here it fails to trigger the match for 'true'.
if (checked == "true") {
     active = i;
     Toast.makeText(DatabaseTestActivity.this, "Found Check", Toast.LENGTH_LONG).show();
}

Any idea on what I am doing wrong ? It’s just a simple string compare, or so I thought ??

Answer 1

Use String.equals() to compare strings.

if (checked.equals("true")) {

}
