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;
    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;
  }

Android 中如何设置activity的启动动画,让它像dialog一样从底部往上出来
在 Android 中实现 Activity 的对话框式过渡动画:从底部滑入与从顶部滑出。需定义两个 XML 动画文件 `activity_slide_in.xml` 和 `activity_slide_out.xml`,分别控制 Activity 的进入与退出动画。使用 `overridePendingTransition` 方法在启动 (`startActivity`) 或结束 (`finish`) Activity 时应用这些动画。为了使前 Activity 保持静止,可定义 `no_animation.xml` 并在启动新 Activity 时仅设置新 Activity 的进入动画。
