KShareViewActivityManager

一个兼容Android 5.0 以下Shared Element Transition (页面间共享元素位移动画)库

精简到了一个类

2016 1 25 更新 支持TextView 的子类颜色渐变了

效果图: 将就看吧

最近开发了一个APP 名字叫番茄ToDo,是一个番茄钟和ToDoList结合的APP(对,我就是嫌番茄土豆太难用太反人类了自己写的)喜欢的朋友可以支持一下:D,各大应用商店都可以下载。

先说缺点吧:在第一个Activity 中的目标View 是wrap_content 时,位移会偏移一点点

使用方法:

##A->B

1.在第一个Activity中:

  img = (ImageView) findViewById(R.id.img);
  title = (TextView) findViewById(R.id.title);
  KShareViewActivityManager.getInstance(MainActivity.this).startActivity(MainActivity.this, SecondActivity.class,R.layout.activity_main,R.layout.activity_second, img, title);

第三个参数是要进行动画的View 所在的layout 的xml ,举例:如果要对ListView 的Item 进行动画,请传入item 布局的xml。

第四个参数 R.layout.activity_second 传入的是第二个Activity 的布局layout id,之后的参数是指需要共享元素动画的View

如何让Manager 知道是哪两个View 在页面之间对应呢?tag 一样即可,如:activity_main 中:

 <ImageView
         android:id="@+id/img"
         android:layout_width="100dp"
         android:layout_height="100dp"
         android:layout_marginLeft="25dp"
         android:layout_marginTop="25dp"
         android:background="@drawable/splash"
         android:tag="img" />

在activity_second 中:

 <ImageView
         android:id="@+id/img_two"
         android:layout_width="250dp"
         android:layout_height="250dp"
         android:layout_centerInParent="true"
         android:background="@drawable/splash"
         android:tag="img" />

tag一样即可

##B->A (回退)

请在ActivityB 中添加:

@Override
public void onBackPressed() {
    KShareViewActivityManager.getInstance(SecondActivity.this).finish(SecondActivity.this);
}

##注意事项

因为是直接操作的Content 显示区域,所以支持Activity ,Fragment 互相跳,只要是在屏幕中显示的View,都可以进行动画

由于进行动画的View 并不是原来的View,而是重新inflate 出来的,因此部分自定义属性并没有被赋值,Manager 对常见的TextView 和ImageView 的部分属性参照原View进行了复制,但如果是其他View的其他属性,还请在 changeViewProperty(View view) 这个回调函数中对其自定义属性进行设置。 如:

  KShareViewActivityManager.getInstance(this).withAction(new KShareViewActivityAction() {
                    @Override
                    public void onAnimatorStart() {
                    }
                    @Override
                    public void onAnimatorEnd() {
                    }
                    @Override
                    public void changeViewProperty(View view) {
                        if(view.getTag().equals("text")){
                            ((MyTextView)view).setOtherProperty(oringinTextView.getOtherProperty);
                        }
                        if(view.getTag().equals("xxx")){
                            ...
                        }
                    }
                });

好啦

##其他用法(添加监听器,设置动画时间),以下是第二张效果图的代码:

  KShareViewActivityManager.getInstance(this).withAction(new KShareViewActivityAction() {
                    @Override
                    public void onAnimatorStart() {
                    }
                    @Override
                    public void onAnimatorEnd() {
                    }
                    @Override
                    public void changeViewProperty(View view) {
                        view.setBackgroundColor(0x00ffffff);
                    }
                }).setDuration(1000).startActivity(this, CountDownActivity.class, R.layout.list_item, R.layout.activity_count_down,
                                 (View) ((CommandEvent) event).obj);

差点忘了,还可以 withIntent 来自定义Intent ,同时 withIntentAndRequestCode(Intent intent,int requestCode) 也可以达到startActivityForResult 的目的。
