android 桌面悬浮窗 录屏时间控制显示效果

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
