11.dialog底部弹出动画:

点击Button调用代码

 private void show() {
        Dialog dialog = new Dialog(this);
        //去掉标题线
        dialog.requestWindowFeature(android.view.Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.dialog);
        //背景透明
        dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
        dialog.show();

        Window window = dialog.getWindow();
        WindowManager.LayoutParams lp = window.getAttributes();
        lp.gravity = Gravity.CENTER; // 居中位置
        lp.width = WindowManager.LayoutParams.MATCH_PARENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
        window.setAttributes(lp);
        window.setWindowAnimations(R.style.mystyle);  //添加动画
    }

Dialog的自定义布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="300dp"
        android:layout_height="wrap_content"
        android:background="@drawable/dialog"
        android:gravity="center"
        android:orientation="vertical"
        android:padding="10dp">

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="用户名" />

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="密码" />

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="确定" />
    </LinearLayout>
</LinearLayout>

Dialog的自定义布局Share样式,drawable里面新建

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <!--圆角-->
    <corners android:radius="30dp" />

    <!--填充色-->
    <solid android:color="#ffffff" />
</shape>

弹出动画样式,在styles里面添加

 <!--弹窗动画-->
    <style name="mystyle" parent="android:Animation">
        <!--//进入时的动画-->
        <item name="@android:windowEnterAnimation">@anim/dialog_enter</item>
        <!--//退出时的动画-->
        <item name="@android:windowExitAnimation">@anim/dialog_exit</item>
    </style>

弹出动画,新建anim文件目录,一个进入 一个退出的,

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="500"
        android:fromYDelta="100%"
        android:toYDelta="0" />
</set>

退出的

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="500"
        android:fromYDelta="0"
        android:toYDelta="100%" />
</set>
