How can I dynamically change number of lines of the TextView in Android?

I have a TextView in which I have to display a large amount of text, but I don't want to show all the text, only three lines and add a button Click to read more, and after clicking on it all the text must expand. How I can implement this functionality and change the number of lines of the text dynamically?

Most likely you are looking for setLines() method. All what you need is to register OnClickListener for Button and perform appropriate action:

t = (TextView) findViewById(R.id.textViewId);
t.setLines(3);

btn.setOnClickListener(new OnClickListener() {          
   @Override
   public void onClick(View v) {
      t.setLines(8);
   }
});

You can use TextView.setMaxLines(...) or TextView.setLines(...).
