策略模式模板模式

设计模式是对事物抽象整理的一种设计思想，他们通过相互组合形成程序设计。策略模式定义自己查就不说了，直接代码体现.

1.设置策略模式算法接口

package com.directional.viewpager.sample.stratery;

/**
 * @version V:2.0.0
 * @Title IStatery
 * @Package com.directional.viewpager.sample.stratery
 * @Description:
 * @date 2016/9/9 9:47
 */

public interface IFlyStatery {
    void doFly();
}

2.对接口实现一系列策略算法

package com.directional.viewpager.sample.stratery;

import android.util.Log;

/**

 * @Title BirdFlyStatery
 * @Package com.directional.viewpager.sample.stratery
 * @Description:
 * @date 2016/9/9 9:48
 */

public class BirdFlyStatery implements IFlyStatery {
    @Override
    public void doFly() {
        Log.e("Emerson","小鸟高飞！！！！！");
    }
}

package com.directional.viewpager.sample.stratery;

import android.util.Log;

/**
 * @version V:2.0.0
 * @Title ChikenFlyStrategy
 * @Package com.directional.viewpager.sample.stratery
 * @Description:
 * @date 2016/9/9 9:50
 */

public class ChikenFlyStrategy implements IFlyStatery {
    @Override
    public void doFly() {
        Log.e("Emerson","小鸡低飞￥￥￥￥￥￥￥￥");
    }
}

3.事物实例

package com.directional.viewpager.sample.stratery;

/**
 * @version V:2.0.0
 * @Title Bird
 * @Package com.directional.viewpager.sample.stratery
 * @Description:
 * @date 2016/9/9 9:54
 */
public class Bird extends FlyModel {

    public Bird(){
        super();
        super.setIFyStatery(new BirdFlyStatery());
    }

}

package com.directional.viewpager.sample.stratery;

/**
 * @version V:2.0.0
 * @Title Bird
 * @Package com.directional.viewpager.sample.stratery
 * @Description:
 * @date 2016/9/9 9:54
 */

public class Chiken extends FlyModel {

    public Chiken(){
        super();
        super.setIFyStatery(new ChikenFlyStrategy());
    }

}

3.设置模板模式模板类

package com.directional.viewpager.sample.stratery;

import android.util.Log;

/**
 * @author zhanghongfei
 * @version V:2.0.0
 * @Title FlyModel
 * @Package com.directional.viewpager.sample.stratery
 * @Description:
 * @date 2016/9/9 9:51
 */

public abstract class FlyModel{

    private IFlyStatery mIFyStatery;

    public void setIFyStatery(IFlyStatery iFyStatery){
        mIFyStatery = iFyStatery;
    }

    public void executeFeature(){
        fly();
        feed();
    }

    public void fly(){
        mIFyStatery.doFly();
    }

    public void feed(){
        Log.e("Emerson","-------------feed");
    }

}

4.调用java测试，

FlyModel bird =newBird();

FlyModel chiken = new Chiken();
bird.executeFeature();
chiken.executeFeature();
