修改文件清单
具体实现
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。
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
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;
this.y = y;
this.randomY = randomY;

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

}
public void setX(float x) {
this.x = x;
}
public float getY() {
return y;
}
public void setY(float y) {

}
}新增充电动画自定义 view
