这里写图片描述

代码：

    public void showCustomDialog(){        LinearLayout customView = new CustomDialogView(this);        AlertDialog mDialog = new AlertDialog.Builder(this,R.style.DialogAtBottom)                .setView(customView)                .setTitle(null)                .create();        Window window = mDialog.getWindow();        WindowManager.LayoutParams lp = window.getAttributes();        window.setGravity(Gravity.BOTTOM);        window.setAttributes(lp);        mDialog.show();    }

    <style name="Animation.Dialog.ShowAtBottom" parent="android:Animation">        <item name="android:windowEnterAnimation">@anim/slide_in_from_bottom</item>        <item name="android:windowExitAnimation">@anim/slide_out_from_bottom</item>    </style>    <style name="DialogAtBottom" >        <item name="android:windowBackground">@drawable/dialog_show_at_bottom</item>        <item name="android:windowMinWidthMajor">100%</item>        <item name="android:windowMinWidthMinor">100%</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowAnimationStyle">@style/Animation.Dialog.ShowAtBottom</item>    </style>

dialog_show_at_bottom.xml

<?xml version="1.0" encoding="utf-8"?><inset xmlns:android="http://schemas.android.com/apk/res/android" >    <shape android:shape="rectangle">        <corners android:radius="1dp" />        <solid android:color="#ffffff" />    </shape></inset>

slide_in_from_bottom.xml

<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android"           android:interpolator="@android:anim/decelerate_interpolator"           android:fromYDelta="50%p" android:toYDelta="0"           android:duration="150"/>

slide_out_from_bottom.xml

<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android"           android:interpolator="@android:anim/accelerate_interpolator"           android:fromYDelta="0" android:toYDelta="50%p"           android:duration="150"/>

AlertDialog实现旋转屏幕不消失

在AndroidManifest activity中加入下面设置

android:configChanges="keyboardHidden|orientation|screenSize"

据说2.3及以下的版本只需要

orientation|keyboardHidden

即可。
