Question

我在这里看到类似的东西，但我无法用给出的解决方案来解决。我试图在Android Studio项目中将视频作为启动画面启动，它在开头正确启动但它不在屏幕中间居中，它位于顶部，我做错了什么？在项目本身没有出现任何错误，一切正常，只有视频没有集中。注意：我对Android Studio没有太多经验，所以如果代码中有一些无意义的内容，请纠正我。

的AndroidManifest.xml：

<!-- Activities -->
        <activity
            android:name="com.sherdle.universal.splash_demo"
            android:theme="@style/AppThemeBar"
            android:configChanges="orientation|screenSize"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="com.sherdle.universal.MainActivity" />

Answer 1

尝试使用具有VideoView属性的相对布局替换LinearLayout android：layout_centerInParent =“true”

Video Splash不在屏幕中央 - Android Studio
