builde.gradle:

 compile 'com.github.tibolte:elasticdownload:1.0.+'

測试代码例如以下：BaseActivity.java

import android.app.Activity;

import android.content.pm.ActivityInfo;

import android.os.Bundle;

import com.lidroid.xutils.ViewUtils;

/**

public abstract class BasicActivity extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        config();

        setContentView(getLayoutID());

        //Annotations view

        ViewUtils.inject(this);

        initView();

    }

    /*

    * The annotation of the control of the UI update

    * Method is protected ,child activity super..

    * */

    protected void initView() {

    }

    /*

    * Config application theme style,such as no title bar, or status bar, transparent, etc

    * Method is protected,child activity super ..

    **/

    protected void config() {

    }

    /*

    * Build contentView id

    * onCreate(Bundle saveInstanceState)>setContentView(R.layout.activity_main)

    * R.layout.activity_main=getlayoutId();

    * */

    public abstract int getLayoutID();

    @Override

    protected void onResume() {

        // TODO Auto-generated method stub

        if (getRequestedOrientation() != ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) {

            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

        }

        super.onResume();

    }

}

    @OnClick(R.id.startDownload)

    public void onClick(View v) {

        String url = "http://img0.bdstatic.com/img/image/6446027056db8afa73b23eaf953dadde1410240902.jpg";

                mDownloadView.fail();

            }

        };

    }

}

界面颜色配置參照Library value color:

<?xml version="1.0" encoding="utf-8"?>

<resources>

    <color name="orange_salmon">#EC5745</color>

    <color name="red_wine">#A6463A</color>

    <color name="red_wood">#4B1D17</color>

    <color name="green_grass">#109121</color>

</resources>

备注：该測试demo用android studio 开发的，假设须要转换成Eclipse project,须要下载相关依赖：

同一时候要注意版本号要求：Android v2.2+。个别特效仅仅支持Api14+
