Android动画
Animation动画
- Frame动画

通常电影里面的画面持续时间长为一秒24帧这里写图片描述
直接看代码吧

这里写图片描述

<?xml version="1.0" encoding="utf-8"?><layoutAnimation    xmlns:android="http://schemas.android.com/apk/res/android"    android:delay="0.5"    android:animationOrder="normal"    android:animation="@anim/translateanimation"></layoutAnimation>

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:duration="1000">  <translate android:fromXDelta="-100%"         android:toXDelta="0"/></set>

这里写图片描述

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.myanimotor.AnimationLayoutActivity"    android:orientation="vertical">  <Button      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:id="@+id/btn_add"      android:text="添加一条数据"      android:textSize="20sp"/>    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:id="@+id/btn_delete"        android:textSize="20sp"/>    <CheckBox        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:id="@+id/checkbox_appear"        android:text="出现新的控件"        android:textSize="20sp"        />    <CheckBox        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:id="@+id/checkbox_disappear"        android:text="出现新的view，其他控件的动画"        android:textSize="20sp"        />    <CheckBox        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:id="@+id/checkbox1"        android:text="即将消失的view动画"        android:textSize="20sp"        />    <CheckBox        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:id="@+id/checkbox2"        android:text="出现新的控件"        android:textSize="20sp"        />    <GridLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:id="@+id/grid_view"        android:columnCount="1">    </GridLayout></LinearLayout>

强调内容
四种补间动画都需要在res文件夹下新建anim文件夹，里面放置动画的xml文件
