[android-developers] Re: Android custom ImageView fade animation
Hi, I tried it but it doesn't seem to work :( Here's my code in the
view that triggers the thread code in the activity:
case MotionEvent.ACTION_DOWN:
currentTouchIndex = checkForSquareTouch(X, Y);
if (currentTouchIndex = 0)
{
((MainActivity) this.getContext())
.playSquareAnimation(currentTouchIndex);
Activity code:
public void playSquareAnimation(int currentTouchIndex)
{
ranim = AnimationUtils.loadAnimation(this, R.anim.rotate);
// view.squares[currentTouchIndex].startAnimation(ranim);
runOnUiThread(new Runnable()
{
public void run()
{
view.clock.startAnimation(AnimationUtils.loadAnimation(
MainActivity.this,
R.anim.rotate));
}
});
}
Any ideas?
Do you think my view's onDraw() method is messing around with the
animation?

[android-developers] Re: Android custom ImageView fade animation
Just to clarify, if I change
view.clock.startAnimation(AnimationUtils.loadAnimation(
MainActivity.this,
R.anim.rotate));
to:
view.startAnimation(AnimationUtils.loadAnimation(
MainActivity.this,
R.anim.rotate));
Then the animation plays, but for the whole view, which isn't what I
want

It takes too much time when your try to allocate memory for Paint
object. If you work withanimationit always calls invalidate() method
which redraws your View. Memory allocation for Paint should be outside
of onDraw() method (e.g. when you create your view, in it's
constructor) it will give you much better perfomance that you have
now. Try to do so and you'll see.

[android-developers] Re: Android custom ImageView fade animation
Bump: Can anyone help? If I define an imageview in my activity and
then set an animation for it, then it plays fine. But if I define an
image view as a member in my custom view and then try to play its
animation, it does not play. Any help is appreciated...

I am creating a game. Most of the computation is done in acustomView

Here's some code to describe what's happening:

public GameView(Context context, AttributeSet a) {
super(context, a);
setFocusable(true);
}
@Override

public void restartGame()

public boolean onTouchEvent(MotionEvent event) {
int eventaction = event.getAction();
int X = (int)event.getX();
int Y = (int)event.getY();
switch (eventaction)
{
case MotionEvent.ACTION_DOWN:
currentTouchIndex = checkForSquareTouch(X, Y);
if(currentTouchIndex = 0)
{
squares[currentTouchIndex].select();
((MainActivity)this.getContext()).startSquareAnimation();
.
return true;
}
Thats the main View. Square implementation:
public class Square extendsImageView{
public Square(Context context, AttributeSet attrs, int x, int y,
int squareWidth, boolean operator, int textS, Typeface f) {
super(context, attrs);
{
this.setImageResource(R.drawable.chalkbox);
this.getDrawable().setBounds(x, y, x + squareWidth, y +
squareWidth);
this.setAlpha(10);
}
protected void onDraw(Canvas canvas) {
Paint foreground = new Paint(Paint.ANTI_ALIAS_FLAG);
foreground.setStyle(Style.FILL);
foreground.setTextSize(textSize);
foreground.setColor(Color.WHITE);
foreground.setTextScaleX(1);
foreground.setTextAlign(Paint.Align.CENTER);
foreground.setTypeface(font);
int left = this.getDrawable().getBounds().left;
int right = this.getDrawable().getBounds().right;
int top = this.getDrawable().getBounds().top;
int bottom = this.getDrawable().getBounds().bottom;
if (invalidMove) {
}
if (isOperator) {
if (text.equals(+))
bottom += 10;
if (text.equals(/))
bottom += 5;
if (text.equals(x) || text.equals(/))
foreground.setTextSize(textSize - 5);
else
foreground.setTextSize(textSize);
}
this.getDrawable().draw(canvas);
canvas.drawText(text, (left + right) / 2, ((top + bottom) / 2) +
10, foreground);
}
Hope that gives you a view of the structure. I'm trying to animate the
Square, so that when a player presses on a Square, the Square
brightens and then fades again when they lift their finger off. The
problem is that the call to square[0].startAnimation() does not seem
to be working and theanimationis not playing. Am I doing something
wrong?
