Suppose I have a layout file in xml.In this I have 3 textviews .I want each to display for one condition i.e. one at a time only.Can I do that in xml ? Which view should I change to enable it if not textview.From the java file I want this check to happen and accordinly the correct message should show .Please give me a solution for this.

You can't do such conditions, and why would you? You just can change the text in the TextView to reflect the 3 different versions.

Or you can also change visibility for your views to show / hide them...
