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
