本文实例为大家分享了android桌面悬浮窗，实现录屏时间控制显示效果的具体代码，供大家参考，具体内容如下

悬浮窗效果如上图所示：

很简单的一个布局直接上代码

悬浮窗布局如下record_screen_time_float.xml

android:layout_width="wrap_content"

android:layout_height="wrap_content">

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:background="@drawable/corners_bg"

android:paddingBottom="3dp"

android:paddingTop="3dp"

android:paddingLeft="15dp"

android:paddingRight="8dp"

android:layout_gravity="center"

android:gravity="center"

android:orientation="horizontal">

android:id="@+id/record_time"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="00:00"

android:textColor="#ffffff"

android:textSize="10dp" />

android:layout_width="2dp"

android:layout_height="match_parent"

android:layout_marginLeft="5dp"

android:layout_marginRight="5dp"

android:textColor="#ffffff" />

android:id="@+id/stop_record"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center"

android:gravity="center"

android:orientation="horizontal">

android:id="@+id/record_hint_button"

android:layout_width="10dp"

android:layout_height="10dp"

android:layout_marginRight="5dp"

android:background="#FF4040" />

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="结束"

android:textColor="#ffffff"

android:textSize="10dp" />

悬浮窗是在service中拉起可以根据个人需要修改
