android 實(shí)現(xiàn)控件左右或上下抖動(dòng)教程
差不多一年前在自己的項(xiàng)目中用過這效果,雖然很簡單,但還是寫寫。
1、首先在你的res目錄下新建anim子目錄,并在anim目錄下新建兩個(gè)文件:
(1)shake.xml文件(位移/平移:translate),設(shè)置起始的位移范圍、效果時(shí)間、循環(huán)次數(shù)
<?xml version='1.0' encoding='utf-8'?><translate xmlns:android='http://schemas.android.com/apk/res/android' android:fromXDelta='0' android:toXDelta='10' android:duration='500' android:interpolator='@anim/share_cycle'> <!--. fromXDelta:x軸起點(diǎn)抖動(dòng)位置 toXDelta:x軸終點(diǎn)抖動(dòng)位置 duration:循環(huán)播放的時(shí)間 interpolator:循環(huán)不放設(shè)置(次數(shù)) --></translate>
(2)cycle.xml文件,控制循環(huán)次數(shù)
<?xml version='1.0' encoding='utf-8'?><cycleInterpolator xmlns:android='http://schemas.android.com/apk/res/android' android:cycles='2'><!--. 循環(huán)次數(shù) --></cycleInterpolator><!--. 循環(huán)播放 -->
最后給你的控件設(shè)置改動(dòng)畫屬性
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);ivShake.startAnimation(shake);
這里ivShake是ImageView,就是這么簡單。
2、個(gè)人碰到一個(gè)問題就是在Activity實(shí)現(xiàn)監(jiān)聽中添加動(dòng)畫效果第一次沒有反應(yīng),不知道為什么
補(bǔ)充知識(shí):Android 抖動(dòng)提示動(dòng)畫
左右抖動(dòng)
ObjectAnimator animator = ObjectAnimator.ofFloat(textView, 'translationX', 0, 100, -100,0);animator.setDuration(200);animator.start();
重復(fù)左右抖動(dòng)
Animation translateAnimation = new TranslateAnimation(-20, 20, 0, 0);translateAnimation.setDuration(100);//每次時(shí)間translateAnimation.setRepeatCount(10);//重復(fù)次數(shù)/**倒序重復(fù)REVERSE 正序重復(fù)RESTART**/translateAnimation.setRepeatMode(Animation.REVERSE);nope.startAnimation(translateAnimation); public static void Shakeview( View view) { Animation translateAnimation = new TranslateAnimation(-10, 10, 0, 0); translateAnimation.setDuration(50);//每次時(shí)間 translateAnimation.setRepeatCount(10);//重復(fù)次數(shù)/**倒序重復(fù)REVERSE 正序重復(fù)RESTART**/ translateAnimation.setRepeatMode(Animation.REVERSE); view.startAnimation(translateAnimation); }
左右上下抖動(dòng)
ObjectAnimator animator = tada(clickMe);animator.setRepeatCount(ValueAnimator.INFINITE);animator.start(); public static ObjectAnimator tada(View view) { return tada(view, 2f);} public static ObjectAnimator tada(View view, float shakeFactor) { PropertyValuesHolder pvhScaleX = PropertyValuesHolder.ofKeyframe(View.SCALE_X, Keyframe.ofFloat(0f, 1f), Keyframe.ofFloat(.1f, .9f), Keyframe.ofFloat(.2f, .9f), Keyframe.ofFloat(.3f, 1.1f), Keyframe.ofFloat(.4f, 1.1f), Keyframe.ofFloat(.5f, 1.1f), Keyframe.ofFloat(.6f, 1.1f), Keyframe.ofFloat(.7f, 1.1f), Keyframe.ofFloat(.8f, 1.1f), Keyframe.ofFloat(.9f, 1.1f), Keyframe.ofFloat(1f, 1f) ); PropertyValuesHolder pvhScaleY = PropertyValuesHolder.ofKeyframe(View.SCALE_Y, Keyframe.ofFloat(0f, 1f), Keyframe.ofFloat(.1f, .9f), Keyframe.ofFloat(.2f, .9f), Keyframe.ofFloat(.3f, 1.1f), Keyframe.ofFloat(.4f, 1.1f), Keyframe.ofFloat(.5f, 1.1f), Keyframe.ofFloat(.6f, 1.1f), Keyframe.ofFloat(.7f, 1.1f), Keyframe.ofFloat(.8f, 1.1f), Keyframe.ofFloat(.9f, 1.1f), Keyframe.ofFloat(1f, 1f) ); PropertyValuesHolder pvhRotate = PropertyValuesHolder.ofKeyframe(View.ROTATION, Keyframe.ofFloat(0f, 0f), Keyframe.ofFloat(.1f, -3f * shakeFactor), Keyframe.ofFloat(.2f, -3f * shakeFactor), Keyframe.ofFloat(.3f, 3f * shakeFactor), Keyframe.ofFloat(.4f, -3f * shakeFactor), Keyframe.ofFloat(.5f, 3f * shakeFactor), Keyframe.ofFloat(.6f, -3f * shakeFactor), Keyframe.ofFloat(.7f, 3f * shakeFactor), Keyframe.ofFloat(.8f, -3f * shakeFactor), Keyframe.ofFloat(.9f, 3f * shakeFactor), Keyframe.ofFloat(1f, 0) ); return ObjectAnimator.ofPropertyValuesHolder(view, pvhScaleX, pvhScaleY, pvhRotate). setDuration(1000);}
