Android上的热火锅煮萝卜蔬菜的Loading动画效果。 这是一个锅煮萝卜的Loading动画，效果仿照自之前IOS上看到的一个效果，觉得挺有意思，就移植过来了，在此完成了Dialog的样式，方便使用者作为LoadingView去使用。
关键性代码：
package yellow5a5.demo.boilingloadingview.View; import android.animation.Animator; import android.animation.AnimatorListenerAdapter; import android.animation.ValueAnimator; import android.content.Context; import android.graphics.drawable.ClipDrawable; import android.os.Handler; import android.os.Message; import android.util.AttributeSet; import android.util.TypedValue; import android.view.LayoutInflater; import android.view.View; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.widget.ImageView; import android.widget.RelativeLayout; import java.util.Timer; import java.util.TimerTask; import yellow5a5.demo.boilingloadingview.R; /** * Created by Weiwu on 16/1/2. */ public class BoilingPanView extends RelativeLayout { private View mView; private ClipDrawable mWaterDrawable; private WaterView mWaterView; private FlameView mFlameView; private View mPea1; private View mPea2; private ImageView mPotato; private ImageView mCarrot; private ImageView mCoverView; private Animation mLeftInAnim; private Animation mRightInAnim; private boolean isRightRotate = true; private ValueAnimator mCoverAnim; private BoilingAnimListener mBoilingAnimListener; public interface BoilingAnimListener { //初始动画结束监听 void onFirstAnimEnd(); } public void setBoilingAnimListener(BoilingAnimListener l) { this.mBoilingAnimListener = l; } private Handler mHandle = new Handler(new Handler.Callback() { @Override public boolean handleMessage(Message msg) { if (msg.what == 0X0000) { mWaterDrawable.setLevel(mWaterDrawable.getLevel() + 800); } return false; } }); public BoilingPanView(Context context) { this(context, null); } public BoilingPanView(Context context, AttributeSet attrs) { this(context, attrs, 0); } public BoilingPanView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); mView = LayoutInflater.from(context).inflate(R.layout.boiling_pan, this, true); initView(); initStartAnim(); initCoverAnim(); } private void initView() { mWaterView = (WaterView) mView.findViewById(R.id.img_water); mFlameView = (FlameView) mView.findViewById(R.id.flame); mCoverView = (ImageView) mView.findViewById(R.id.img_cover); mPea1 = mView.findViewById(R.id.img_pea1); mPea2 = mView.findViewById(R.id.img_pea2); mPotato = (ImageView) mView.findViewById(R.id.img_potato); mCarrot = (ImageView) mView.findViewById(R.id.img_carrot); mWaterDrawable = (ClipDrawable) mWaterView.getDrawable(); } private void initStartAnim() { mLeftInAnim = AnimationUtils.loadAnimation(getContext(), R.anim.left_in_anim); mRightInAnim = AnimationUtils.loadAnimation(getContext(), R.anim.right_in_anim); } /* 抖动的盖子 */ private void initCoverAnim() { mCoverAnim = ValueAnimator.ofFloat(0f, 1f, 0f).setDuration(800); mCoverAnim.setRepeatMode(Animation.REVERSE); mCoverAnim.setRepeatCount(-1); mCoverAnim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() { @Override public void onAnimationUpdate(ValueAnimator animation) { float value = (float) animation.getAnimatedValue(); if (isRightRotate) { mCoverView.setRotation(value * 5); } else { mCoverView.setRotation(-value * 5); } mCoverView.setTranslationY(-value * TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 5, getResources().getDisplayMetrics())); } }); mCoverAnim.addListener(new AnimatorListenerAdapter() { @Override public void onAnimationRepeat(Animator animation) { super.onAnimationRepeat(animation); isRightRotate = !isRightRotate; } }); } /* 开始启动的动画 */ public void beginFirstInAnim() { mPea1.setVisibility(VISIBLE); mPea2.setVisibility(VISIBLE); mPotato.setVisibility(VISIBLE); mCarrot.setVisibility(VISIBLE); mCoverView.setVisibility(VISIBLE); mPea1.startAnimation(mLeftInAnim); mPea2.startAnimation(mLeftInAnim); mPotato.startAnimation(mLeftInAnim); mCarrot.startAnimation(mRightInAnim); mCoverView.startAnimation(mRightInAnim); mRightInAnim.setAnimationListener(new Animation.AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { if (mBoilingAnimListener != null) { //这里是为了给外部留有操作的空间 mBoilingAnimListener.onFirstAnimEnd(); } else { beginBoilingAnim(); } } @Override public void onAnimationRepeat(Animation animation) { } }); } /* 开始加水燃火动画 */ public void beginBoilingAnim() { final Timer timer = new Timer(); timer.schedule(new TimerTask() { @Override public void run() { mHandle.sendEmptyMessage(0X0000); if (mWaterDrawable.getLevel() >= 10000) { timer.cancel(); } } }, 0, 50); mFlameView.startFlaming(); mCoverAnim.start(); } /* 重置动画 */ public void resetAnim() { mWaterDrawable.setLevel(0); mWaterView.resetBubbleAnim(); mFlameView.stopFlaming(); mPea1.setVisibility(INVISIBLE); mPea2.setVisibility(INVISIBLE); mPotato.setVisibility(INVISIBLE); mCarrot.setVisibility(INVISIBLE); mCoverView.setVisibility(INVISIBLE); } }
希望本文所述对大家学习Android软件编程有所帮助。
