Android 帧动画实现自定义loading加载框

动画加载框

通过动画实现

1.定义res/drawable/drawable_anim.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<animation-list android:oneshot="false" xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@mipmap/progress_1" android:duration="50" />
    <item android:drawable="@mipmap/progress_2" android:duration="50" />
    <item android:drawable="@mipmap/progress_3" android:duration="50" />
    <item android:drawable="@mipmap/progress_4" android:duration="50" />
    <item android:drawable="@mipmap/progress_5" android:duration="50" />
    <item android:drawable="@mipmap/progress_6" android:duration="50" />
    <item android:drawable="@mipmap/progress_7" android:duration="50" />
    <item android:drawable="@mipmap/progress_8" android:duration="50" />
    <item android:drawable="@mipmap/progress_9" android:duration="50" />
    <item android:drawable="@mipmap/progress_10" android:duration="50" />
    <item android:drawable="@mipmap/progress_11" android:duration="50" />
    <item android:drawable="@mipmap/progress_12" android:duration="50" />
    <item android:drawable="@mipmap/progress_13" android:duration="50" />
    <item android:drawable="@mipmap/progress_14" android:duration="50" />
    <item android:drawable="@mipmap/progress_15" android:duration="50" />
    <item android:drawable="@mipmap/progress_16" android:duration="50" />
    <item android:drawable="@mipmap/progress_17" android:duration="50" />
    <item android:drawable="@mipmap/progress_18" android:duration="50" />
    <item android:drawable="@mipmap/progress_19" android:duration="50" />
    <item android:drawable="@mipmap/progress_20" android:duration="50" />
    <item android:drawable="@mipmap/progress_21" android:duration="50" />
    <item android:drawable="@mipmap/progress_22" android:duration="50" />
    <item android:drawable="@mipmap/progress_23" android:duration="50" />
    <item android:drawable="@mipmap/progress_24" android:duration="50" />
    <item android:drawable="@mipmap/progress_25" android:duration="50" />
    <item android:drawable="@mipmap/progress_26" android:duration="50" />
    <item android:drawable="@mipmap/progress_27" android:duration="50" />
    <item android:drawable="@mipmap/progress_28" android:duration="50" />
    <item android:drawable="@mipmap/progress_29" android:duration="50" />
    <item android:drawable="@mipmap/progress_30" android:duration="50" />
    <item android:drawable="@mipmap/progress_31" android:duration="50" />
    <item android:drawable="@mipmap/progress_32" android:duration="10" />
</animation-list>

2.定义values/styles.xml如下：

<!-- 自定义dialog背景全透明无边框 -->
    <style name="MyDialog" parent="android:style/Theme.Dialog">

        <!-- 背景颜色及和透明程度 -->
        <item name="android:windowBackground">@android:color/transparent</item>
        <!-- 是否去除标题 -->
        <item name="android:windowNoTitle">true</item>
        <!-- 是否去除边框 -->
        <item name="android:windowFrame">@null</item>
        <!-- 是否浮现在activity之上 -->
        <item name="android:windowIsFloating">true</item>
        <!-- 是否模糊 -->
        <item name="android:backgroundDimEnabled">false</item>
    </style>

3.自定义Dialog

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

        //点击imageview外侧区域，动画不会消失
        setCanceledOnTouchOutside(false);

        progressImg = (ImageView) findViewById(R.id.refreshing_drawable_img);
        //加载动画资源
        animation = (AnimationDrawable) progressImg.getDrawable();
    }

4.创建加载框布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/refreshing_drawable_img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:scaleType="fitCenter"
        android:src="@drawable/drawable_anim" />
</RelativeLayout>

通过图片实现

1.定义res/anim/alpha_in.xml如下：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <rotate
        android:duration="200"
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:repeatCount="-1"
        android:toDegrees="360" />
</set>

2.自定义Dialog

    public IconDrawableDialog(Context context) {
        super(context, R.style.MyDialog);
        //点击imageview外侧区域，动画不会消失
        setCanceledOnTouchOutside(false);
        init();
    }

    private void init() {
        setContentView(R.layout.icon_drawable_dialog_layout);
        iv_route = (ImageView) findViewById(R.id.iv_route);
        detail_tv = (TextView) findViewById(R.id.detail_tv);
        tv_point = (TextView) findViewById(R.id.tv_point);
        initAnim();
        getWindow().setWindowAnimations(R.anim.alpha_in);
    }

    private void initAnim() {
        // mAnim = new RotateAnimation(360, 0, Animation.RESTART, 0.5f,
        // Animation.RESTART, 0.5f);
        mAnim = new RotateAnimation(0, 360, Animation.RESTART, 0.5f, Animation.RESTART, 0.5f);
        mAnim.setDuration(500);
        mAnim.setRepeatCount(Animation.INFINITE);
        mAnim.setRepeatMode(Animation.RESTART);
        mAnim.setStartTime(Animation.START_ON_FIRST_FRAME);
    }

3.创建加载框布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="100dp"
    android:layout_gravity="center"
    android:paddingRight="30dp"
    android:background="@mipmap/dialog_background"
    android:orientation="horizontal">

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="100dp"
        android:layout_marginLeft="20dp"
        android:gravity="center_vertical">

        <ImageView
            android:id="@+id/iv_route"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:background="@mipmap/dialog"></ImageView>
    </RelativeLayout>

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="100dp"
        android:layout_marginLeft="20dp"
        android:gravity="center_vertical">

        <TextView
            android:id="@+id/detail_tv"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ellipsize="marquee"
            android:gravity="center"
            android:singleLine="true"
            android:text="正在加载"
            android:textColor="#000000"
            android:textSize="20sp" />

        <TextView
            android:id="@+id/tv_point"
            android:layout_width="20dp"
            android:layout_height="wrap_content"
            android:layout_toRightOf="@+id/detail_tv"
            android:text="..."
            android:textColor="#000000"
            android:textSize="20sp" />
    </RelativeLayout>

</LinearLayout>

以上是两种常用的加载框样式，由于时间有限，只贴了主要的代码，所以，如有需要，以下提供下载地址。
由于图片较多，所以rar包有点大。下载地址:http://download.csdn.net/detail/liu_ling1216/9728944
