Android 直播 聊天輸入法彈出 視頻不擠壓 解決方案

參考網上已有方案，即使用DialogFragment佈局聊天列表、聊天框、禮物等內容。

需要兩個Fragment，底下Fragment放視頻View，上層即DialogFragment。

注意，經過測試視頻層必須放置在Fragment裏邊，若直接視頻放置在Activity佈局，達不到我們要的效果！！！

網上其他DialogFragment方案均說到直播Activity在清單中鍵盤彈出方式爲 android:windowSoftInputMode="adjustPan" ，經過我的測試無需此設置

demo效果：

AndroidManifest.xml

        <activity
            android:name=".fragment3.LiveVideo3Activity"
            android:screenOrientation="portrait">

                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
