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>
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
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 0-1 0全然透明 1 全然不透明 --> </alpha>
<?xml version="1.0" encoding="utf-8"?> <rotate android: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"?> <scale android: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> <!-- fromXScale 1 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="@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);
}
}
