Here firstly we create an string array and create dynamic TextView using setFactory method and then load and set slide in left and slide in right animation and finally set the text in the TextSwitcher on button click using setText method. Whenever a user click on next button TextSwitcher switch between the labels and the current label will go out and next label will come in with specified animation.<\/p>\n
