TransitionDrawable 动画

此示例显示仅具有两个图像的图像视图的事务。（在每个事务作为循环之后，可以使用更多图像以及第一和第二层位置的一个接一个）

• 将图像数组添加到 res/values/arrays.xml

<resources>

    <array
        name="splash_images">
        <item>@drawable/spash_imge_first</item>
        <item>@drawable/spash_img_second</item>
    </array>

</resources>

    private Drawable[] backgroundsDrawableArrayForTransition;
    private TransitionDrawable transitionDrawable;

private void backgroundAnimTransAction() {

        // set res image array
        Resources resources = getResources();
        TypedArray icons = resources.obtainTypedArray(R.array.splash_images);

        @SuppressWarnings("ResourceType")
        Drawable drawable = icons.getDrawable(0);    // ending image

        @SuppressWarnings("ResourceType")
        Drawable drawableTwo = icons.getDrawable(1);   // starting image

        backgroundsDrawableArrayForTransition = new Drawable[2];
        backgroundsDrawableArrayForTransition[0] = drawable;
        backgroundsDrawableArrayForTransition[1] = drawableTwo;
        transitionDrawable = new TransitionDrawable(backgroundsDrawableArrayForTransition);

        // your image view here - backgroundImageView
        backgroundImageView.setImageDrawable(transitionDrawable);
        transitionDrawable.startTransition(4000);

        transitionDrawable.setCrossFadeEnabled(false); // call public methods  

      
    }
