动画自定义对话框 [英] Animate a custom Dialog

问题描述

我试图让自定义对话框看起来好像是从文本视图中滑下来的.这可能吗?我似乎无法将任何动画应用于对话框类.我在构造函数中试过这一行，但没有效果:

I'm trying to have a custom dialog appear as though it's sliding down from a text view. Is this possible? I can't seem to apply any animation to dialog class. I've tried this line in the constructor, but it has no effect:

this.getWindow().setWindowAnimations(R.anim.paranimation);

this.getWindow().setWindowAnimations(R.anim.paranimation);

我什至不确定动画是否正确，但是一旦我看到它在做什么，我就可以调整它.为了完整起见，我将在下面列出它.我不是在寻求有关实际动画的帮助，只是寻求对话框的应用程序.

I'm not even sure if the animation is correct, but I will be able adjust it once I see what it's doing. I'll list it below for the sake of completeness. I'm not looking for help on the actual animation, just the application to the dialog.

参数.xml:

<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="-200%"
    android:toXDelta="0%"
    android:fromYDelta="200%"
    android:toYDelta="0%"
    android:duration="3000"
    android:zAdjustment="top">
</translate>

推荐答案

今天我一直在为 Dialog 动画苦苦挣扎，终于使用样式让它工作了，所以这里有一个例子.

I've been struggling with Dialog animation today, finally got it working using styles, so here is an example.

首先，最重要的事情 — 我今天可能让它以 5 种不同的方式工作，但无法确定，因为...如果您的设备动画设置设置为无动画"(设置 → 显示 → 动画)然后无论你做什么，对话框都不会被动画化！

To start with, the most important thing — I probably had it working 5 different ways today but couldn't tell because... If your devices animation settings are set to "No Animations" (Settings → Display → Animation) then the dialogs won't be animated no matter what you do!

以下是我的styles.xml 的精简版.希望它是不言自明的.这应该位于 res/values 中.

The following is a stripped down version of my styles.xml. Hopefully it is self-explanatory. This should be located in res/values.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="PauseDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowAnimationStyle">@style/PauseDialogAnimation</item>
    </style>

    <style name="PauseDialogAnimation">
        <item name="android:windowEnterAnimation">@anim/spin_in</item>
        <item name="android:windowExitAnimation">@android:anim/slide_out_right</item>
    </style>
</resources>

windowEnterAnimation 是我的动画之一，位于 res\anim.windowExitAnimation 是 Android SDK 中的动画之一.

The windowEnterAnimation is one of my animations and is located in res\anim. The windowExitAnimation is one of the animations that is part of the Android SDK.

然后当我在我的活动 onCreateDialog(int id) 方法中创建对话框时，我执行以下操作.

Then when I create the Dialog in my activities onCreateDialog(int id) method I do the following.

Dialog dialog = new Dialog(this, R.style.PauseDialog);

// Setting the title and layout for the dialog
dialog.setTitle(R.string.pause_menu_label);
dialog.setContentView(R.layout.pause_menu);

或者，您可以通过以下方式设置动画，而不是使用带有主题的 Dialog 构造函数.

Alternatively you could set the animations the following way instead of using the Dialog constructor that takes a theme.

Dialog dialog = new Dialog(this);
dialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;
