來(lái)自同事_Smile的封裝應(yīng)用，記錄學(xué)習(xí)一下

1、AnimImageViewLoader類(lèi)的封裝

/**
 * 適用于animation-list 動(dòng)畫(huà)
 * Created by _Smile on 2016/6/13.
 */

public class AnimImageViewLoader extends ImageView {

    private AnimationDrawable frameAnimation;

    public AnimImageViewLoader(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    public AnimImageViewLoader(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public AnimImageViewLoader(Context context) {
        super(context);
        init();
    }

    /**
     * 初始化動(dòng)畫(huà)信息
     */
    private void init() {
        frameAnimation = (AnimationDrawable) getBackground();
        post(new Runnable(){
            public void run(){
                frameAnimation.start();
            }
        });
    }

    /**
     * 開(kāi)啟動(dòng)畫(huà)顯示
     */
    public void startAnimation() {
        frameAnimation = (AnimationDrawable) getBackground();
        post(new Runnable() {
            @Override
            public void run() {
                frameAnimation.start();
            }
        });
    }

    /**
     * 關(guān)閉動(dòng)畫(huà)顯示
     */
    public void stopAnimation() {
        post(new Runnable() {
            @Override
            public void run() {
                frameAnimation.stop();
            }
        });
    }
}

2、布局文件

 <com.tecsun.tsb.res.widget.AnimImageViewLoader
                android:id="@+id/aiv_take_id_card_pic"
                style="@style/style_wrap_content"
                android:layout_alignTop="@id/iv_id_card_take_pic_main"
                android:background="@drawable/anim_id_card_positive_pic" />

3、在代碼中的調(diào)用

  AnimImageViewLoader aivIdCardPic = xFindViewById(R.id.aiv_take_id_card_pic);
  aivIdCardPic.setBackgroundResource(R.drawable.anim_id_card_negative_pic);
  aivIdCardPic.startAnimation();

4、R.drawable.anim_id_card_negative_pic文件內(nèi)容

<?xml version="1.0" encoding="utf-8"?>
<!--圖片動(dòng)畫(huà)-->
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@mipmap/ic_id_card_negative_01" android:duration="300"/>
    <item android:drawable="@mipmap/ic_id_card_negative_02" android:duration="300"/>
    <item android:drawable="@mipmap/ic_id_card_negative_03" android:duration="300"/>
    <item android:drawable="@mipmap/ic_id_card_negative_04" android:duration="300"/>
    <item android:drawable="@mipmap/ic_id_card_negative_05" android:duration="300"/>
    <item android:drawable="@mipmap/ic_id_card_negative_06" android:duration="300"/>

</animation-list>
