android dialog加载中动画效果

//显示动画

dialog = new Dialog(context, R.style.loading);
		dialog.setContentView(R.layout.loadinglayout);//此处布局为一个progressbar
		dialog.setCancelable(true); // 可以取消
		dialog.show();
		WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
		params.height = -1;
		params.width = -1;
		params.format=1;
		params.flags = LayoutParams.FLAG_FULLSCREEN | LayoutParams.FLAG_LAYOUT_IN_SCREEN;
		dialog.getWindow().setAttributes(params);

 

 

dialog.cancel(); //去掉dialog

 

 //dialog中设置的布局progressbar

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

    <ProgressBar
        android:id="@+id/loadingbar"
        style="@style/loadingStyle"

        android:layout_height="130dp"
        android:layout_gravity="center">
    </ProgressBar>

</LinearLayout>

 

//dialog和progressbar分别用的style

 <!-- 使用frame动画制作的logo炫动效果 -->
    <style name="loadingStyle">
        <item name="android:indeterminateDrawable">@anim/loading</item>
    </style>

    <style name="loading">
        <item name="android:layout_width">fill_parent</item>
        <item name="android:layout_height">fill_parent</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:backgroundDimEnabled">false</item> <!-- 模糊 -->
        <item name="android:windowIsFloating">true</item><!-- 类似windows的弹出Dialog -->
        <item name="android:windowContentOverlay">@null</item><!-- 不要头部阴影 -->
          <item name="android:windowBackground">@color/transparent</item>   <!-- 背景颜色设置透明-->
    </style>
