Android---06---2中动画效果 _android

厌伴老儒烹瓠叶，强随举子踏槐花。这篇文章主要讲述Android---06---2中动画效果相关的知识，希望能为你提供帮助。
1，先看FrameAnimation，此动画是用来实现动态动画就是把一帧帧图片迭代起来
放在drowable中的xml：

< ?xml version="1.0" encoding="utf-8"?
> < animation-list xmlns:android="http://schemas.android.com/apk/res/android" > < item android:drawable="@drawable/ben_window_0001" android:duration="60" /> < item android:drawable="@drawable/ben_window_0002" android:duration="60" /> < item android:drawable="@drawable/ben_window_0003" android:duration="60" /> < item android:drawable="@drawable/ben_window_0004" android:duration="60" /> < item android:drawable="@drawable/ben_window_0005" android:duration="60" /> < item android:drawable="@drawable/ben_window_0006" android:duration="60" /> < item android:drawable="@drawable/ben_window_0007" android:duration="60" /> < item android:drawable="@drawable/ben_window_0008" android:duration="60" /> < item android:drawable="@drawable/ben_window_0009" android:duration="60" /> < item android:drawable="@drawable/ben_window_0010" android:duration="60" /> < item android:drawable="@drawable/ben_window_0011" android:duration="60" /> < item android:drawable="@drawable/ben_window_0012" android:duration="60" /> < item android:drawable="@drawable/ben_window_0013" android:duration="60" /> < item android:drawable="@drawable/ben_window_0014" android:duration="60" /> < item android:drawable="@drawable/ben_window_0015" android:duration="60" /> < item android:drawable="@drawable/ben_window_0016" android:duration="60" /> < item android:drawable="@drawable/ben_window_0017" android:duration="60" /> < item android:drawable="@drawable/ben_window_0018" android:duration="60" /> < item android:drawable="@drawable/ben_window_0019" android:duration="60" /> < item android:drawable="@drawable/ben_window_0020" android:duration="60" /> < item android:drawable="@drawable/ben_window_0021" android:duration="60" /> < item android:drawable="@drawable/ben_window_0022" android:duration="60" /> < item android:drawable="@drawable/ben_window_0023" android:duration="60" /> < item android:drawable="@drawable/ben_window_0024" android:duration="60" /> < item android:drawable="@drawable/ben_window_0025" android:duration="60" /> < item android:drawable="@drawable/ben_window_0026" android:duration="60" /> < item android:drawable="@drawable/ben_window_0027" android:duration="60" /> < item android:drawable="@drawable/ben_window_0028" android:duration="60" /> < /animation-list>

Activity中：

package com.example.frameanimation; import android.app.Activity; import android.graphics.drawable.AnimationDrawable; import android.os.Bundle; import android.view.View; import android.widget.Button; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } public void startAnimation(View v) {Button btn=(Button)v; //得到动画对象 AnimationDrawable anim=(AnimationDrawable)btn.getBackground(); //启动动画 anim.start(); }}

这样我点击一个Tomcat就会循环的动

然后是补间动画

文章图片

先看这些xml文件

< ?
xml version="1.0" encoding="utf-8"?> < alpha android:fromAlpha="0.1" android:toAlpha="1" android:duration="5000"xmlns:android="http://schemas.android.com/apk/res/android"> < !--透明度 0-10全然透明1 全然不透明 --> < /alpha>

< ?
xml version="1.0" encoding="utf-8"?> < rotateandroid:fromDegrees="0" android:toDegrees="360" android:duration="500" android:pivotX="50%" android:pivotY="50%"android:interpolator="@android:anim/accelerate_interpolator" android:repeatCount="infinite"android:repeatMode="reverse" xmlns:android="http://schemas.android.com/apk/res/android"> < !-- repeatCount反复次数infinite 无限 repeatMode反复模式 interpolator加速器 --> < /rotate>

< ?
xml version="1.0" encoding="utf-8"?> < scaleandroid:fromXScale="0.5" android:fromYScale="0.5"android:toXScale="2" android:toYScale="2"android:pivotX="50%" android:pivotY="50%" android:duration="200" android:repeatMode="reverse" android:repeatCount="infinite" xmlns:android="http://schemas.android.com/apk/res/android"> < /scale> < !-- fromXScale1本身状态 -->

< ?xml version="1.0" encoding="utf-8"?
> < translate xmlns:android="http://schemas.android.com/apk/res/android"android:fromXDelta="0" android:fromYDelta="0"android:toXDelta="0" android:toYDelta="80%p"android:duration="100" android:repeatMode="reverse" android:repeatCount="infinite" > < /translate>

主文件里的xml
无非就是一张图片加上几个button

< RelativeLayout 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=".MainActivity" > < ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="84dp" android:src="https://www.songbingjia.com/android/@drawable/heart" android:id="@+id/myimg" /> < Button android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBaseline="@+id/button2" android:layout_alignBottom="@+id/button2" android:layout_alignRight="@+id/myimg" android:text="缩放" android:onClick="scale" /> < Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_below="@+id/myimg" android:layout_marginLeft="32dp" android:onClick="alpha" android:text="alpha" /> < Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBaseline="@+id/button1" android:layout_alignBottom="@+id/button1" android:layout_marginRight="35dp" android:layout_toLeftOf="@+id/button3" android:onClick="rotate" android:text="旋转" /> < Button android:id="@+id/button4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignLeft="@+id/button1" android:layout_below="@+id/button1" android:text="位移动画" android:onClick="translate" /> < /RelativeLayout>

然后在Activity中调用这些动画

package com.example.tweenanimation; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.widget.ImageView; public class MainActivity extends Activity { private ImageView image; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); image = (ImageView) findViewById(R.id.myimg); } // 运行透明动画 public void alpha(View v) { // 1.载入动画资源 Animation anim = AnimationUtils.loadAnimation(MainActivity.this, R.anim.alpha); // 2.运行动画 image.startAnimation(anim); } //运行旋转动画 public void rotate(View v) { Animation anim = AnimationUtils.loadAnimation(MainActivity.this, R.anim.rotate); image.startAnimation(anim); } //缩放动画 public void scale(View v) { Animation anim = AnimationUtils.loadAnimation(MainActivity.this, R.anim.scale); image.startAnimation(anim); } public void translate(View v) {Animation anim = AnimationUtils.loadAnimation(MainActivity.this, R.anim.translate); image.startAnimation(anim); } }
