Android动画效果学习

1、透明动画效果

方法一：代码实现

	public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
		{
			View rootView = inflater.inflate(R.layout.fragment_main, container, false);
			
			rootView.findViewById(R.id.btnAnimMe).setOnClickListener(new View.OnClickListener()
			{
				
				@Override
				public void onClick(View v)
				{
					AlphaAnimation aa = new AlphaAnimation(0, 1);
					aa.setDuration(1000);
					v.startAnimation(aa);
									}
			});
			
			return rootView;
		}

 方法二，用配置文件的形式

第一步，新建一个aa.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha
    android:fromAlpha="0"
    android:toAlpha="1"
    android:duration="1000"
    xmlns:android="http://schemas.android.com/apk/res/android">
    

</alpha>

 第二步，代码调用 

		public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
		{
			View rootView = inflater.inflate(R.layout.fragment_main, container, false);
			
			rootView.findViewById(R.id.btnAnimMe).setOnClickListener(new View.OnClickListener()
			{
				
				@Override
				public void onClick(View v)
				{
					v.startAnimation(AnimationUtils.loadAnimation(getActivity(), R.anim.aa));
				}
			});
			
			return rootView;
		

 

 

2、旋转动画效果

第一种实现方式：代码

	private RotateAnimation ra;

	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		ra = new RotateAnimation(0, 360, 100, 50);
		ra = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
		ra.setDuration(1000);
		
		
		findViewById(R.id.btnRotateme).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(ra);
			}
		});
	

 第二种实现方式：配置文件

<?xml version="1.0" encoding="utf-8"?>
<rotate
    android:fromDegrees="0"
    android:toDegrees="360"
    android:duration="1000"
    android:pivotX="50%"  
    android:pivotY="50%"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- pivotY写数值当像素解析，写百分比，就是相对自身的百分比 -->
    

</rotate>

 代码部分：

protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		findViewById(R.id.btnRotateme).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.ra));
			}
		});
	}

 

3、移动动画效果

第一种：代码实现方式

private TranslateAnimation ta;
	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		ta = new TranslateAnimation(0, 200, 0, 200);//是增量的概念， 相对自身当前来说，向右移动200像素，向下移动200像素
		ta.setDuration(1000);
		
		findViewById(R.id.btnTranslateMe).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(ta);
			}
		});
	}

 第二种配置文件方式

<?xml version="1.0" encoding="utf-8"?>
<translate
    android:fromXDelta="0"
    android:toXDelta="200"
    android:fromYDelta="0"
    android:toYDelta="200"
    android:duration="1000"
    xmlns:android="http://schemas.android.com/apk/res/android">
    

</translate>

 

protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		findViewById(R.id.btnTranslateMe).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.ta));
			}
		});
	}

 

 

4、缩放动画效果

第一种代码实现：

private ScaleAnimation sa;
	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
//		sa = new ScaleAnimation(0, 1, 0, 1); //
//		sa = new ScaleAnimation(0, 1, 0, 1, 100, 50);
		sa = new ScaleAnimation(0, 1, 0, 1, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);//相对自己的中心点来绽放
		sa.setDuration(1000);
		findViewById(R.id.btnScaleMe).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(sa);
			}
		});
	}

 第二种配置文件：

<?xml version="1.0" encoding="utf-8"?>
<scale
    android:fromXScale="0"
    android:toXScale="1"
    android:fromYScale="0"
    android:toYScale="1"
    android:duration="1000"
    android:pivotX="50%"
    android:pivotY="50%"
    xmlns:android="http://schemas.android.com/apk/res/android">
    

</scale>

 代码部分：

	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		findViewById(R.id.btnScaleMe).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.sa));;
			}
		});
	

 5、混合动画效果

第一种代码实现

private AnimationSet as;
	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		as = new AnimationSet(true);//是否共用动画补间，动画执行的过程，匀速，加速，减速执行，这个为动画补间
		as.setDuration(1000);
		
		AlphaAnimation aa = new AlphaAnimation(0, 1);
		aa.setDuration(1000);
		as.addAnimation(aa);
		
		TranslateAnimation ta = new TranslateAnimation(200, 0, 200, 0);
		ta.setDuration(1000);
		as.addAnimation(ta);
		
		findViewById(R.id.btnAnimMe).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(as);
			}
		});
	}

 

第二种配置文件方式：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:shareInterpolator="true" >

    <alpha
        android:fromAlpha="0"
        android:toAlpha="1" />

    <translate
        android:fromXDelta="200"
        android:fromYDelta="200"
        android:toXDelta="0"
        android:toYDelta="0" />

</set>

 代码部分：

protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		findViewById(R.id.btnAnimMe).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.anim));;
			}
		});
	}

 

6、动画侦听

protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		findViewById(R.id.btnAnimMe).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				Animation animation = AnimationUtils.loadAnimation(MainActivity.this, R.anim.anim);
				animation.setAnimationListener(new Animation.AnimationListener()
				{
					
					@Override
					public void onAnimationStart(Animation animation)
					{
						Toast.makeText(MainActivity.this, "Animation start", Toast.LENGTH_SHORT).show();
					}
					
					@Override
					public void onAnimationRepeat(Animation animation)
					{
						Toast.makeText(MainActivity.this, "Animation repeat", Toast.LENGTH_SHORT).show();
					}
					
					@Override
					public void onAnimationEnd(Animation animation)
					{
						Toast.makeText(MainActivity.this, "Animation End", Toast.LENGTH_SHORT).show();
					}
				});
				v.startAnimation(animation);;
			}
		});
	}

 

7、自定义动画效果，比如单击按钮后，让按钮摇摆

第一步自定义一个类，继承自Animation

package com.michael.lcustomanimation;

import android.view.animation.Animation;
import android.view.animation.Transformation;

public class CustomAnim extends Animation
{
	
	@Override
	public void initialize(int width, int height, int parentWidth, int parentHeight)
	{
		System.out.println("init");
		super.initialize(width, height, parentWidth, parentHeight);
	}
	
	@Override
	protected void applyTransformation(float interpolatedTime, Transformation t)
	{
		//interpolatedTime 从0-1  
		System.out.println(interpolatedTime);

//		t.setAlpha(interpolatedTime);
//		t.getMatrix().setTranslate(200, 200);//这个会直接跳过去，不是我们想要的移动的效果，分别剩上一个补间就可以了，我们可以随意自定义动画 
//		t.getMatrix().setTranslate(200*interpolatedTime, 200*interpolatedTime);
		
		//比如在登录窗口，密码错了，我们给他一个这样的效果
		t.getMatrix().setTranslate((float) (Math.sin(interpolatedTime*10)*50), 0);//需要周期性的运动，数学里面有很多这样的函数，比如sin   
		
		super.applyTransformation(interpolatedTime, t);
	}
}

 代码调用

private CustomAnim ca;
	@Override
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		ca = new CustomAnim();
		ca.setDuration(1000);
		
		findViewById(R.id.btnAnimMe).setOnClickListener(new View.OnClickListener()
		{
			
			@Override
			public void onClick(View v)
			{
				v.startAnimation(ca);
			}
		});
	}
