    1. COevery time a textview gets scaled: store a reference of the current textview/state. every time a new touch event occurs: check the state of the current textview and do your actions appropriate to the use cases you have given

    2. COThanks but the problem is I am not able to store the reference. I even tried adding a TextView in my LinerLayout and set that TextView's visibility to 0 an I then use the height and width of this hidden TextView to match in the first if inside OnTouch. Still onTouch it always enters the else part.

    3. COgive every textview an id by using the setTag method, now you know which textview is which.. then make an collection of textviews and store states in them.. on every touch you loop this collection and search for the right textview and do appropriate things with it. You should rethink the implementation of handling the touch event.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
