所以,事實證明,這比我想象的要簡單得多。
我創建了一個全屏幕RelativeLayout,我只在動畫發生時顯示。
我得到我喜歡這個埋按鈕的起始位置(這很有趣,看看在Java中使用這些C風格的編碼機制,他們是非常罕見的,這些天:
int fromLoc[] = new int[2];
v.getLocationOnScreen(fromLoc);
float startX = fromLoc[0];
float startY = fromLoc[1];
所以,現在我有我的起點點。
我的終點是一個絕對座標在屏幕上,你可以分配自己的喜好
然後我做一點動畫助手類,它讓我通過在所有的座標,回調,和動畫的持續時間
public class Animations {
public Animation fromAtoB(float fromX, float fromY, float toX, float toY, AnimationListener l, int speed){
Animation fromAtoB = new TranslateAnimation(
Animation.ABSOLUTE, //from xType
fromX,
Animation.ABSOLUTE, //to xType
toX,
Animation.ABSOLUTE, //from yType
fromY,
Animation.ABSOLUTE, //to yType
toY
);
fromAtoB.setDuration(speed);
fromAtoB.setInterpolator(new AnticipateOvershootInterpolator(1.0f));
if(l != null)
fromAtoB.setAnimationListener(l);
return fromAtoB;
}
}
,我們需要一個傾聽者,讓我們知道當動畫做是爲了清除它
AnimationListener animL = new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
//this is just a method to delete the ImageView and hide the animation Layout until we need it again.
clearAnimation();
}
};
最後一點,我們把它放在一起,然後按GO
int fromLoc[] = new int[2];
v.getLocationOnScreen(fromLoc);
float startX = fromLoc[0];
float startY = fromLoc[1];
RelativeLayout rl = ((RelativeLayout)findViewById(R.id.sticker_animation_layout));
ImageView sticker = new ImageView(this);
int stickerId = getStickerIdFromButton(v);
if(stickerId == 0){
stickerAnimationPlaying = false;
return;
}
float destX = 200.0f;//arbitrary place on screen
float destY = 200.0f;//arbitrary place on screen
sticker.setBackgroundResource(stickerId);
sticker.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
rl.addView(sticker);
Animations anim = new Animations();
Animation a = anim.fromAtoB(startX, startY, destX, destY, animL,750);
sticker.setAnimation(a);
a.startNow();
好吧,我理解了它自己,如果沒有人有答案風鈴,我會後,明天,爲他人蔘考。 – 2012-03-09 06:39:13
