自定义圆盘时钟的大概流程：因为圆盘时钟的圆盘是不需要动的，所以不必要加在自定义的view里面，在view里面只需要绘制秒针和分针时针并控其转动即可。

以下就是自定义view的主要代码：

package com.example.chl.myapplication;import android.content.Context;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.graphics.Canvas;import android.graphics.Matrix;import android.graphics.Paint;import android.util.AttributeSet;import android.view.View;/** * Created by chl on 16-3-30. */public class TimeVIew extends View {    private Paint mPaint;    // private Bitmap bitmap = null;    private Bitmap ssBitmap = null;    private Bitmap sssBitmap = null;    private Bitmap mmBitmap = null;    private Bitmap mmmBitmap = null;//    private int x;//    private int y;    private int ssx;    private int ssy;    private int mmx;    private int mmy;    private Context mContext;    private Matrix matrix = null;    private Matrix mmatrix = null;    private float angle = 0;//秒针每秒偏移的角度    private float mangle = 0;//分针每秒偏移的角度    private MyThread myThread;    public TimeVIew(Context context, AttributeSet attrs) {        super(context, attrs);        this.mContext = context;        initBitmap();    }    public TimeVIew(Context context) {        super(context);        this.mContext = context;        initBitmap();    }    public TimeVIew(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);        this.mContext = context;        initBitmap();    }    private void initBitmap() {        mPaint = new Paint();        mPaint.setAntiAlias(true);        BitmapFactory.Options options = new BitmapFactory.Options();        options.inSampleSize = 2;        // bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.global_dial_day_bg,options);        ssBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.global_second_day_small);        mmBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.global_minute_day_small);        // x = bitmap.getWidth();        // y = bitmap.getHeight();        ssx = ssBitmap.getWidth();//获取bitmap的宽度        ssy = ssBitmap.getHeight();        mmx = mmBitmap.getWidth();        mmy = mmBitmap.getHeight();        matrix = new Matrix();        matrix.setRotate(angle);//设置图片旋转角度        mmatrix = new Matrix();        matrix.setRotate(mangle);        sssBitmap = Bitmap.createBitmap(ssBitmap, 0, 0, ssx, ssy, matrix, true);//创建新的bitmap        mmmBitmap = Bitmap.createBitmap(mmBitmap, 0, 0, mmx, mmy, mmatrix, true);    }    @Override    protected void onDraw(Canvas canvas) {        super.onDraw(canvas);        //canvas.drawBitmap(bitmap, Util.getDeviceWidth(mContext) / 2 - x / 2, Util.getDeviceHeight(mContext) / 2 - y / 2, mPaint);        if (myThread == null) {            myThread = new MyThread();            myThread.start();        }        canvas.drawBitmap(mmmBitmap, getWidth() / 2 - mmmBitmap.getWidth() / 2, getHeight() / 2 - mmmBitmap.getHeight() / 2, mPaint);        canvas.drawBitmap(sssBitmap, getWidth() / 2 - sssBitmap.getWidth() / 2, getHeight() / 2 - sssBitmap.getHeight() / 2, mPaint);    }    class MyThread extends Thread {        private int num=0;        @Override        public void run() {            while (true) {                if (angle == 360) {                    angle = 0;                }                if (mangle == 360) {                    mangle = 0;                }                matrix.setRotate(angle);                sssBitmap = Bitmap.createBitmap(ssBitmap, 0, 0, ssx, ssy, matrix, true);                mmatrix.setRotate(mangle);                mmmBitmap = Bitmap.createBitmap(mmBitmap, 0, 0, mmx, mmy, mmatrix, true);                angle += 6;                if (num%5==0) {//控制分针五秒移动一个角度，也可以每秒都让其移动                    mangle += 0.5;                }                num++;                if (num==200){                    num=0;                }                postInvalidate();//重新绘制                try {                    Thread.sleep(1000);                } catch (InterruptedException e) {                    e.printStackTrace();                }            }        }    }}

主布局文件：

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:background="#000000"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    >    <ImageView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/global_dial_day_bg"        />    <com.example.chl.myapplication.TimeVIew        android:layout_width="match_parent"        android:layout_height="match_parent" /></FrameLayout>
