How could I do to shrink the size of textview to Xdp if the text contains more than 15 characters?

You can set the text size at runtime using the TextView method:
setTextSize (float size)
A very easy way will be using a Paint object. You can create one, add a set a text size, and using it's method measureText("some text") you will be able to know width of the text. Having that, you can decide either to split it on multiple lines, or by reducing the text size and checking again until you have a size that fits your screen size.
