android设置图片变化的四种效果代码

activity代码如下：

package com.example.chapter12_graphic_animation;

import android.os.Bundle;

import android.app.Activity;

import android.content.res.Resources;

import android.graphics.drawable.Drawable;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.view.animation.AlphaAnimation;

import android.view.animation.Animation;

import android.view.animation.RotateAnimation;

import android.view.animation.ScaleAnimation;

import android.view.animation.TranslateAnimation;

import android.widget.Button;

import android.widget.ImageView;

public class MainActivity extends Activity {

private Button b1,b2,b3,b4;

private ImageView girlImage;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

Resources res = getResources();

Drawable drawable = res.getDrawable(R.drawable.test);

this.getWindow().setBackgroundDrawable(drawable);

setContentView(R.layout.main);

girlImage=(ImageView)findViewById(R.id.ImageView01);

b1=(Button)findViewById(R.id.Button01);

b2=(Button)findViewById(R.id.Button02);

b3=(Button)findViewById(R.id.Button03);

b4=(Button)findViewById(R.id.Button04);

b1.setOnClickListener(new OnClickListener(){

public void onClick(View arg0) {

//创建Scale尺寸变化动画

Animation scaleAnimation =new ScaleAnimation(0f,1f,0f,1f,

Animation.RELATIVE_TO_SELF,0.5f,

Animation.RELATIVE_TO_SELF,0.5f);

//设置动画持续的时常

scaleAnimation.setDuration(3000);

//开始动画

girlImage.startAnimation(scaleAnimation);

}

});

b2.setOnClickListener(new OnClickListener(){

public void onClick(View arg0) {

//创建Scale尺寸变化动画

Animation alphaAnimation =new AlphaAnimation(0.1f,1.0f);

//设置动画持续的时常

alphaAnimation.setDuration(3000);

//开始动画

girlImage.startAnimation(alphaAnimation);

}

});

b3.setOnClickListener(new OnClickListener(){

public void onClick(View arg0) {

//创建Scale尺寸变化动画

Animation translateAnimation =new TranslateAnimation(10,100,10,100);

//设置动画持续的时常

translateAnimation.setDuration(3000);

//开始动画

girlImage.startAnimation(translateAnimation);

}

});

b4.setOnClickListener(new OnClickListener(){

public void onClick(View arg0) {

//创建Scale尺寸变化动画

Animation rotateAnimation =new RotateAnimation(0f,+360f,

Animation.RELATIVE_TO_SELF,0.5f,

Animation.RELATIVE_TO_SELF,0.5f);

//设置动画持续的时常

rotateAnimation.setDuration(3000);

//开始动画

girlImage.startAnimation(rotateAnimation);

}

});

}

//为按钮添加监听事件

@Override

public boolean onCreateOptionsMenu(Menu menu) {

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

XML代码设置如下：

<?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:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

<Button

android:id="@+id/Button01"
