具体实现

新增布局
vendor/mediatek/proprietary/packages/apps/SystemUI/res/layout/wired_charging_layout.xml

<FrameLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/shcy_charge_view"android:layout_width="match_parent"android:layout_height="match_parent"android:background="#99000000"><com.android.systemui.charging.BubbleViscosityandroid:id="@+id/shcy_bubble_view"android:layout_width="match_parent"android:layout_height="match_parent"/>
</FrameLayout>

新增气泡 bean
vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/charging/BubbleBean.java

package com.android.systemui.charging;public class BubbleBean {private float randomY = 3;private float x;private float y;private int index;public BubbleBean(float x, float y, float randomY, int index) {this.x = x;this.y = y;this.randomY = randomY;this.index = index;}public void set(float x, float y, float randomY, int index) {this.x = x;this.y = y;this.randomY = randomY;this.index = index;}public void setMove(int screenHeight, int maxDistance) {if (y - maxDistance < 110) {this.y -= 2;return;}if (maxDistance <= y && screenHeight - y > 110) {this.y -= randomY;} else {this.y -= 0.6;}if (index == 0) {this.x -= 0.4;} else if (index == 2) {this.x += 0.4;}}public int getIndex() {return index;}public float getX() {return x;}public void setX(float x) {this.x = x;}public float getY() {return y;}public void setY(float y) {this.y = y;}
}
