具体实现

1、新增布局

prize_charge_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<com.android.systemui.charging.KeyguardChargeAnimationViewxmlns:android="http://schemas.android.com/apk/res/android"xmlns:aapt="http://schemas.android.com/aapt"xmlns:androidprv="http://schemas.android.com/apk/prv/res/android"xmlns:sysui="http://schemas.android.com/apk/res-auto"android:id="@+id/keyguard_charge_view"android:layout_width="match_parent"android:layout_height="match_parent"android:background="#e6000000"><ImageViewandroid:id="@+id/dot_view"android:layout_width="200dp"android:layout_height="wrap_content"android:layout_centerInParent="true"android:padding="0dp"android:src="@drawable/prize_charge_dot" /><ImageViewandroid:id="@+id/ring_view"android:layout_width="200dp"android:layout_height="wrap_content"android:layout_centerInParent="true"android:padding="0dp"android:src="@drawable/prize_charge_ring" /><RelativeLayoutandroid:id="@+id/battery_layout"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_centerInParent="true"android:layout_gravity="center"android:gravity="center"android:orientation="horizontal"><LinearLayoutandroid:id="@+id/charge_battery"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center"android:gravity="center"android:orientation="horizontal"><ImageViewandroid:id="@+id/charge_icon"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="1dp"android:layout_marginRight="3dp" /><TextViewandroid:id="@+id/battery_level"android:layout_width="wrap_content"android:layout_height="wrap_content"android:fontFamily="sans-serif-light"android:textColor="#ffffff"android:textSize="28dp" /></LinearLayout><TextViewandroid:id="@+id/battery_prompt"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_below="@+id/charge_battery"android:layout_centerHorizontal="true"android:layout_marginTop="20dp"android:fontFamily="sans-serif-light"android:textColor="#ffffff"android:textSize="14dp" /></RelativeLayout>
</com.android.systemui.charging.KeyguardChargeAnimationView>

2、布局对应的animate java类
