本文例項為大家分享了Android原生視訊播放VideoView的具體程式碼,供大家參考,具體內容如下
佈局檔案activity_video.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <VideoView android:id="@+id/videoView" android:layout_width="match_parent" android:layout_height="match_parent" /> <ProgressBar android:id="@+id/progressBar" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" /> </RelativeLayout>
對應的Avtivity:VideoActivity.java
