Android(安卓)自定义充电动画

不多说，直接上代码
1 首先创建类，类名自定义我这边是直接 BubbleViscosity。

public class BubbleViscosity extends SurfaceView implements SurfaceHolder.Callback, Runnable {    private static ScheduledExecutorService scheduledThreadPool;    private static String texta;    private Context context;    private String paintColor = "#25DA29";// 不透明圆弧的颜色    private String centreColor = "#00000000"; // 中间圆的颜色    private String minCentreColor = "#9025DA29"; //透明的圆弧    private int screenHeight;    private int screenWidth;    private float lastRadius;  // 底部半圆的半径    private float rate = 0.32f;// 底部曲线的控制点    private float rate2 = 0.32f;// 底部曲线的控制点    private PointF lastCurveStrat = new PointF();//底部圆的起点坐标    private PointF lastCurveEnd = new PointF();//底部圆的结束坐标    private PointF centreCirclePoint = new PointF();// 中间圆的坐标    private float centreRadius;//中间圆的 半径    private float bubbleRadius;    // 所有圆弧的坐标数组    private PointF[] arcPointStrat = new PointF[8];    private PointF[] arcPointEnd = new PointF[8];    private PointF[] control = new PointF[8];    private PointF arcStrat = new PointF();    private PointF arcEnd = new PointF();    private PointF controlP = new PointF();    // 气泡的其实点保存集合    List bubbleList = new ArrayList<>();    List bubbleBeans = new ArrayList<>();    private int rotateAngle = 0;  //旋转的角度    private float controlrate = 1.66f; // 圆弧的控制点    private float controlrateS = 1.3f; // 可变圆弧的控制点    private int i = 0;// 无限循环的下标    private SurfaceHolder mHolder;    private float scale = 0;//  圆得开口值    private Paint arcPaint;    private Paint minCentrePaint;    private Paint bubblePaint;    private Paint centrePaint;    private Paint lastPaint;    private Path lastPath; // 所有的路劲    private Random random;    private Paint textPaint;    private Rect rect;    public BubbleViscosity(Context context) {        this(context, null);    }    public BubbleViscosity(Context context, @Nullable AttributeSet attrs) {        this(context, attrs, 0);    }    public BubbleViscosity(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);        this.context = context;        initzi(texta);        initTool();    }    public static BubbleViscosity initzi(String text1) {        texta=text1;        return null;    }    @Override    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        super.onMeasure(widthMeasureSpec, heightMeasureSpec);        screenHeight = getMeasuredHeight();        screenWidth = getMeasuredWidth();        setBubbleList();    }    private void initTool() {        rect = new Rect();        mHolder = getHolder();//获取SurfaceHolder对象        mHolder.addCallback(this);//注册SurfaceHolder的回调方法        setFocusable(true); // 设置焦点        //TODO:保证该SurfaceView在最上层,避免两个SurfaceView叠加，遮挡问题        mHolder.setFormat(PixelFormat.TRANSPARENT);        setZOrderOnTop(true);        lastRadius = dip2Dimension(40f, context);//底部圆的半径        centreRadius = dip2Dimension(100f, context);//中间圆的半径        bubbleRadius = dip2Dimension(10f, context);//气泡的半径        random = new Random();        //底部圆        lastPaint = new Paint();        lastPaint.setAntiAlias(true);        lastPaint.setStyle(Paint.Style.FILL);        lastPaint.setColor(Color.parseColor(paintColor));        lastPaint.setStrokeWidth(2);        lastPath = new Path();        //中间圆的画笔        centrePaint = new Paint();        centrePaint.setAntiAlias(true);        centrePaint.setStyle(Paint.Style.FILL);        centrePaint.setStrokeWidth(2);        centrePaint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_OUT));        centrePaint.setColor(Color.parseColor(centreColor));        // 不透明圆弧的画笔        arcPaint = new Paint();        arcPaint.setAntiAlias(true);        arcPaint.setStyle(Paint.Style.FILL);        arcPaint.setColor(Color.parseColor(paintColor));        arcPaint.setStrokeWidth(2);        //  透明圆弧的画笔        minCentrePaint = new Paint();        minCentrePaint.setAntiAlias(true);        minCentrePaint.setStyle(Paint.Style.FILL);        minCentrePaint.setColor(Color.parseColor(minCentreColor));        minCentrePaint.setStrokeWidth(2);        // 气泡的画笔        bubblePaint = new Paint();        bubblePaint.setAntiAlias(true);        bubblePaint.setStyle(Paint.Style.FILL);        bubblePaint.setColor(Color.parseColor(minCentreColor));        bubblePaint.setStrokeWidth(2);        //文字画笔        textPaint = new Paint();        textPaint.setAntiAlias(true);        textPaint.setStyle(Paint.Style.FILL);        textPaint.setColor(Color.parseColor("#00FF00"));        textPaint.setStrokeWidth(2);        textPaint.setTextSize(dip2Dimension(40f, context));    }

2 这中间有个 BubbleBean 是自己生成出来的

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;//气泡开始的移动的时候比较慢，造成气泡开始的 黏性气泡        }        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;    }}

3 在你想要引用的XML上面直接引用
android:id="@+id/BubbleViscosity"
android:layout_width=“match_parent”
android:layout_height=“match_parent”/>

到这里也就好了，只是显示电量的数字是直接定义好的，大家可以更改的，如果想要获取更全面的代码，欢迎大家去关注一下我公众号在这里我会不定时更新一些新的东西
