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
