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>

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

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);
	}

}
