Android自定义Dialog

给dialog设置的主题风格

<style name="CustomDialog" parent="android:style/Theme.Dialog">
        <!--背景颜色及和透明程度-->
        <item name="android:windowBackground">@android:color/transparent</item>
        <!--是否去除标题 -->
        <item name="android:windowNoTitle">true</item>
        <!--是否去除边框-->
        <item name="android:windowFrame">@null</item>
        <!--是否浮现在activity之上-->
        <item name="android:windowIsFloating">true</item>
        <!--是否模糊-->
        <item name="android:backgroundDimEnabled">false</item>
    </style>

下面是布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    <!--设置背景为黑色半透明-->
    android:background="#c0000000"
    android:orientation="vertical">

    <FrameLayout
        android:layout_gravity="top"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <ImageView
            android:id="@+id/iv_bk_dialog"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="@drawable/dialogcuspon" />
        <ImageView
            android:id="@+id/iv_close_dialog"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="right|center_vertical"
            android:layout_marginRight="@dimen/sm_80"
            android:background="@drawable/close"/>
        <LinearLayout
            android:layout_gravity="center_horizontal|bottom"
            android:layout_marginBottom="@dimen/sm_100"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="horizontal">
            <Button
                android:id="@+id/bt_yes"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/dialog_but1"/>
            <Button
                android:id="@+id/bt_no"
                android:layout_marginLeft="@dimen/sm_10"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/dialog_but2"/>
        </LinearLayout>
    </FrameLayout>

</LinearLayout>

下面是具体的使用

     */
    public static void showCuspon(Context context,int res){            final Custom_dialog custom_dialog=new Custom_dialog(context);

                    MyApplication.shakeFlag=true;
                }
            });            //由于我布置上去发现dialog有点靠下，所以将其动态地部署靠上
           
            custom_dialog.show();            //设置dialog的大小和坐标，一直要放到show()方法的后面
            Window dialogWindow = custom_dialog.getWindow();
        WindowManager.LayoutParams lp = dialogWindow.getAttributes();

        lp.width= WindowManager.LayoutParams.MATCH_PARENT;
        lp.height= WindowManager.LayoutParams.MATCH_PARENT;        //也可以根据屏幕大小来这只dialog的大小，比如屏幕的1/6
        /*
