Class ChangeText

java.lang.Object

Transition

com.transitionseverywhere.ChangeText

public class ChangeText
extends Transition

This transition tracks changes to the text in TextView targets. If the text changes between the start and end scenes, the transition ensures that the starting text stays until the transition ends, at which point it changes to the end text. This is useful in situations where you want to resize a text view to its new size before displaying the text that goes there.

static int	CHANGE_BEHAVIOR_OUT_IN Flag specifying that the text changing animation should first fade out the original text completely and then fade in the new text.

Field Detail

CHANGE_BEHAVIOR_KEEP

public static final int CHANGE_BEHAVIOR_KEEP

Flag specifying that the text in affected/changing TextView targets will keep their original text during the transition, setting it to the final text when the transition ends. This is the default behavior.

setChangeBehavior(int), Constant Field Values

CHANGE_BEHAVIOR_OUT

public static final int CHANGE_BEHAVIOR_OUT

Flag specifying that the text changing animation should first fade out the original text completely. The new text is set on the target view at the end of the fade-out animation. This transition is typically used with a later CHANGE_BEHAVIOR_IN transition, allowing more flexibility than the CHANGE_BEHAVIOR_OUT_IN by allowing other transitions to be run sequentially or in parallel with these fades.

setChangeBehavior(int), Constant Field Values

CHANGE_BEHAVIOR_IN

public static final int CHANGE_BEHAVIOR_IN

Flag specifying that the text changing animation should fade in the end text into the affected target view(s). This transition is typically used in conjunction with an earlier CHANGE_BEHAVIOR_OUT transition, possibly with other transitions running as well, such as a sequence to fade out, then resize the view, then fade in.

setChangeBehavior(int), Constant Field Values

CHANGE_BEHAVIOR_OUT_IN

public static final int CHANGE_BEHAVIOR_OUT_IN

Flag specifying that the text changing animation should first fade out the original text completely and then fade in the new text.
