Dialog弹出Activity及设置是否可点击view外区域

让activity以dialog方式弹出      

<activity
            android:name=".activity.xxxxxActivity"
            android:theme="@style/DialogTheme"
            android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
            android:label="@string/app_name"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="adjustResize" />

方法一：在android:theme="@style/DialogTheme"加入android:windowCloseOnTouchOutside

<style name="DialogTheme" parent="@android:Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowBackground">@drawable/white</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>

        <item name="android:windowCloseOnTouchOutside">false</item> //是否可以点击view外区域
</style>

方法二：在初始化activity时加入，setCanceledOnTouchOutside(false)设置点击空白处不消失

如果能取到dialog对象可直接设置

dialog.setCanceledOnTouchOutside(false);
dialog.setCancelable(false);
