when i use textview.getid(),why the result comes out is not the the one i defined for textview in the xml

Assuming i got 3 data:i=01,j=02,k=03 and i want to set these 3 data indiviually into 3 textViews that defined with ids:@+id/tv01,@+id/tv02,@+id/tv03. The following is what i have tried: 

if (textview.getid().contain(i))
    textView.settext(i)

But when i use textview.getid(), why the result comes out is not the the one i defined for textview in the xml? Any ideas?

Thanks for the help!

When you use textview.getId(), you get the id of the textview as generated in R.java file,and not what you have defined in "@+id/xxx"

So if you want to play around with ids, you should do something like :

    if(textview.getid() == R.id.textview) { 
       // do awesome stuff
    }

if you want to do it same way you are doing. You can manually set the ids of TextView by using setId().

For eg.

TextView tv1 = (TextView) findViewById(R.id.tv01);
TextView tv2 = (TextView) findViewById(R.id.tv02);
tv1.setId(1); 
tv2.setId(2);

and for getting use getId() you will get what you have set.
