我们用到一个SurfaceView来展示视屏效果。这是布局文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:orientation="vertical"> <SurfaceView android:layout_width="match_parent" android:layout_height="300dp" android:id="@+id/sv_main_surfaceview" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/tv_main_end" /> <SeekBar android:layout_width="0dp" android:layout_weight="8" android:layout_height="wrap_content" android:id="@+id/sb_main_seebar" /> <TextView android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/tv_main_static" /> <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_media_play" android:onClick="playorstp" /> </LinearLayout></LinearLayout>

Activity:
