android桌面悬浮窗显示录屏时间控制效果

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

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content"> 
 
 <LinearLayout 
  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"> 
 
  <TextView 
   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" /> 
  <View 
   android:layout_width="2dp" 
   android:layout_height="match_parent" 
   android:layout_marginLeft="5dp" 
   android:layout_marginRight="5dp" 
   android:textColor="#ffffff" /> 
  <LinearLayout 
   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"> 
   <ImageView 
    android:id="@+id/record_hint_button" 
    android:layout_width="10dp" 
    android:layout_height="10dp" 
    android:layout_marginRight="5dp" 
    android:background="#FF4040" /> 
 
   <TextView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="结束" 
    android:textColor="#ffffff" 
    android:textSize="10dp" /> 
  </LinearLayout> 
 </LinearLayout> 
</LinearLayout> 

悬浮窗是在service中拉起可以根据个人需要修改
