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
