Android---06---2中动画效果
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完全透明 1 完全不透明 -->
</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 重复次数 infinite 无限
repeatMode 重复模式
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>
主文件中的xml
无非就是一张图片加上几个按钮
<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=http://www.mamicode.com/"@drawable/heart" >
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);
}
// 执行透明动画
public void alpha(View v) {
// 1.加载动画资源
Animation anim = AnimationUtils.loadAnimation(MainActivity.this,
R.anim.alpha);
// 2.执行动画
image.startAnimation(anim);
}
//执行旋转动画
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);
}
}
