效果图如下

这里写图片描述

功能实现

首先自定义一个WaterWaveView，然后开一个多线程，每隔100ms调用WaterWaveView里的setPercent(percent);方法

public class MURP_School_Schedule_WaterWaveView extends FrameLayout {    private float mPercent;    private Paint mPaint = new Paint();    private Bitmap mBitmap;    private Bitmap mScaledBitmap;    //省略代码    public void setPercent(float percent) {        mFlag = Status.RUNNING;        mPercent = percent;        postInvalidate();    }    public void setTextColor(int color) {        mTextColor = color;    }    @Override    protected void dispatchDraw(Canvas canvas) {        super.dispatchDraw(canvas);        Path path = new Path();        canvas.save();        path.reset();        canvas.clipPath(path);        path.addCircle(width / 2, height / 2, width / 2 - 6, Direction.CCW);        canvas.clipPath(path, Op.REPLACE);        if (mScaledBitmap == null) {                mBitmap = BitmapFactory.decodeResource(getContext().getResources(), R.drawable.student_tree_home);                mScaledBitmap = Bitmap.createScaledBitmap(mBitmap, mBitmap.getWidth(), getHeight(), false);                mBitmap.recycle();                mBitmap = null;                //省略代码        }        String str = (int) (mPercent * 100) + "%";        canvas.drawText(str, (getWidth() - mPaint.measureText(str)) / 2, getHeight() / 2 + mTextSize / 2, mPaint);        //省略代码    }}
