Android 类似于ArcMenu（github上开源项目）的自定义多个按钮视图
浏览数：28 /

最近的项目中有个比较好的开源的多个分享按钮的自定义视图，感觉比较好，所以就研究了下，写了下来。其实这个demo类似于github上开源项目ArcMenu开源项目，项目下载地址为：https://github.com/daCapricorn/ArcMenu。
实现效果图：
1、点击该按钮，五个按钮飞入屏幕；
2、点击五个按钮其中的一个后，改按钮放到直至消失，其余的按钮变小直至消失。
体验感还是挺好的。
再次点击五个按钮飞出屏幕。
好了，下面上源码吧。比较多，但都是些自定义的空间，看两遍就能看懂啦。。
只有一个布局文件：share_layout：
里面定义了布局和按钮，这些都是自定义的布局或按钮。

按钮动画抽象类AbstractInOutAnimationSet，anim包中剩余的其他三个类都集成该抽象类：
package com.anim;
import android.view.View;
import android.view.animation.AnimationSet;
/**

*/
public abstract class AbstractInOutAnimationSet extends AnimationSet {

switch (directioin) {

addInAnimation(views);
break;

}
// 添加完动画之后再设置执行总时间
setDuration(duration);
}

return mDirectioin;
}
/**

*/
protected abstract void addInAnimation(View[] views);
/**

protected abstract void addOutAnimation(View[] views);
}
弹出收回按钮移动轨迹动画集合PopupButtonAnimationSet：
package com.anim;
import android.view.View;
import android.view.ViewGroup;
import android.view.animation.TranslateAnimation;
/**

}
/** 480 * 800手机上值变化规律

float y = layoutParams.bottomMargin + mYOffset;
TranslateAnimation animation = new TranslateAnimation(0.0F, x, 0.0F, y);
addAnimation(animation);
}
}
点击按钮放大并消失动画集合ClickAnimationSet：
package com.anim;
import android.view.View;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.ScaleAnimation;
/**

*/
public class ClickAnimationSet extends AbstractInOutAnimationSet {
public ClickAnimationSet(long duration) {
super(Direction.OUT, duration, null);
}
@Override
protected void addInAnimation(View[] views) {
}
@Override
protected void addOutAnimation(View[] views) {
addAnimation(new ScaleAnimation(1.0F, 5.0F, 1.0F, 5.0F, 1, 0.5F,
Animation.RELATIVE_TO_SELF, 0.5F));
addAnimation(new AlphaAnimation(1.0F, 0.0F));
}
}
弹出收回按钮点击后动画NotClickAnimationSet：
package com.anim;
import android.view.View;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.ScaleAnimation;
/**
* 弹出收回按钮点击后动画
*/
public class NotClickAnimationSet extends AbstractInOutAnimationSet {
public NotClickAnimationSet(long duration) {
// 只是控制直接调用addOutAnimation
super(Direction.OUT, duration, null);
}
@Override
protected void addInAnimation(View[] views) {
}
@Override
protected void addOutAnimation(View[] views) {
addAnimation(new ScaleAnimation(1.0F, 0.0F, 1.0F, 0.0F,
Animation.RELATIVE_TO_SELF, 0.5F, 1, 0.5F));
addAnimation(new AlphaAnimation(1.0F, 0.0F));
}
}
下面就是在布局中引用过的自定义布局、自定义按钮：
自定义布局InOutRelativeLayout：
package com.customview;
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationSet;
import android.widget.RelativeLayout;
import com.anim.AbstractInOutAnimationSet;
import com.anim.AbstractInOutAnimationSet.Direction;
public class InOutRelativeLayout extends RelativeLayout {
private Animation mAnimation;
public InOutRelativeLayout(Context context) {
super(context);
}
public InOutRelativeLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public InOutRelativeLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onAnimationStart() {
super.onAnimationStart();
if (mAnimation instanceof AnimationSet) {
setVisibility(View.VISIBLE);
}
}
@Override
protected void onAnimationEnd() {
super.onAnimationEnd();
if (mAnimation instanceof AbstractInOutAnimationSet) {
AbstractInOutAnimationSet animationSet = (AbstractInOutAnimationSet) mAnimation;
if (animationSet.getDirection() == Direction.OUT) {
setVisibility(View.GONE);
} else {
setVisibility(View.VISIBLE);
}
}
}
@Override
public void startAnimation(Animation animation) {
super.startAnimation(animation);
mAnimation = animation;
getRootView().postInvalidate();
}
}
弹出，收回按钮InOutImageButton：
package com.customview;
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.animation.Animation;
import android.widget.ImageButton;
import com.anim.AbstractInOutAnimationSet;
/**
* 弹出，收回按钮
*/
public class InOutImageButton extends ImageButton {
private Animation mAnimation;
public InOutImageButton(Context context) {
super(context);
}
public InOutImageButton(Context context, AttributeSet attrs) {
super(context, attrs);
}
public InOutImageButton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onAnimationStart() {
super.onAnimationStart();
if (mAnimation instanceof AbstractInOutAnimationSet) {
setVisibility(View.VISIBLE);
}
}
@Override
protected void onAnimationEnd() {
super.onAnimationEnd();
if (mAnimation instanceof AbstractInOutAnimationSet) {
AbstractInOutAnimationSet animation = (AbstractInOutAnimationSet) mAnimation;
if (animation.getDirection() == com.anim.AbstractInOutAnimationSet.Direction.OUT) {
setVisibility(View.GONE);
} else {
setVisibility(View.VISIBLE);
}
}
}
@Override
public void startAnimation(Animation animation) {
super.startAnimation(animation);
mAnimation = animation;
getRootView().postInvalidate();
}
}
基本就是这些，下面我提供下源码，大家可以结合下源码看:
