根据系统原有的无线充电动画流程，新增有线充电气泡动画。
效果图
修改文件清单
vendor/mediatek/proprietary/packages/apps/systemui/src/com/android/systemui/statusbar/phone/statusbar.java vendor/mediatek/proprietary/packages/apps/systemui/res/layout/wired_charging_layout.xml vendor/mediatek/proprietary/packages/apps/systemui/src/com/android/systemui/charging/bubblebean.java vendor/mediatek/proprietary/packages/apps/systemui/src/com/android/systemui/charging/bubbleviscosity.java vendor/mediatek/proprietary/packages/apps/systemui/src/com/android/systemui/charging/wiredcharginganimation.java
具体实现
新增布局
vendor/mediatek/proprietary/packages/apps/systemui/res/layout/wired_charging_layout.xml
<framelayout
xmlns: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.bubbleviscosity
android: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;

}
public void set(float x, float y, float randomy, int index) {

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;
}
}
