前言

                     前不久在网上看见Android实现的模拟时钟，感觉十分有意思，这里是地址：

                http://www.eoeandroid.com/forum.php?mod=viewthread&tid=58324可惜的是这种方式没有

                秒表。笔者突然对其有了兴趣，也想去实现以下自己的模拟时钟。折腾了一阵子总算是弄出来了

                现在将实现方式共享出来，大家一些交流。

                     不多说，先上效果图：

                     

                     

         准备工作

                    首先我们应该准备相关的素材：时钟盘、时针、分针、秒针图片.

                    时钟盘：

                                    

                             时针：

                                                  

                            分针：

                                                  

                            秒针：     

                                                 

              源码部分

                              配置文件，比较简单：                     

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical"tools:context=".MainActivity"android:background="@color/bg"><com.kiritor.mymodelclock.MyQAnalogClockandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center"/>
</LinearLayout>

                         MyQAnalogClock代码：用于构造时钟view以及其刷新显示：   

package com.kiritor.mymodelclock;import android.util.AttributeSet;
import com.kiritor.mymodelclock.R;
import android.content.Context;
import android.graphics.*;
import android.graphics.drawable.BitmapDrawable;
import android.os.Handler;
import android.view.View;
import java.util.Calendar;
import java.util.TimeZone;
/*** Created by Kiritor on 13-5-30.*/
public class MyQAnalogClock extends View {//时钟盘，分针、秒针、时针对象Bitmap mBmpDial;Bitmap mBmpHour;Bitmap mBmpMinute;Bitmap mBmpSecond;BitmapDrawable bmdHour;BitmapDrawable bmdMinute;BitmapDrawable bmdSecond;BitmapDrawable bmdDial;Paint mPaint;Handler tickHandler;int mWidth;int mHeigh;int mTempWidth = bmdSecond.getIntrinsicWidth();int mTempHeigh;int centerX;int centerY;int availableWidth = 100;int availableHeight = 100;private String sTimeZoneString;public MyQAnalogClock(Context context,AttributeSet attr){this(context,"GMT+8：00");}public MyQAnalogClock(Context context, String sTime_Zone) {super(context);sTimeZoneString = sTime_Zone;mBmpHour = BitmapFactory.decodeResource(getResources(),R.drawable.shizhen);bmdHour = new BitmapDrawable(mBmpHour);mBmpMinute = BitmapFactory.decodeResource(getResources(),R.drawable.fenzhen);bmdMinute = new BitmapDrawable(mBmpMinute);mBmpSecond = BitmapFactory.decodeResource(getResources(),R.drawable.miaozhen);bmdSecond = new BitmapDrawable(mBmpSecond);mBmpDial = BitmapFactory.decodeResource(getResources(),R.drawable.android_clock_dial);bmdDial = new BitmapDrawable(mBmpDial);mWidth = mBmpDial.getWidth();mHeigh = mBmpDial.getHeight();centerX = availableWidth / 2;centerY = availableHeight / 2;mPaint = new Paint();mPaint.setColor(Color.BLUE);run();}public void run() {tickHandler = new Handler();tickHandler.post(tickRunnable);}private Runnable tickRunnable = new Runnable() {public void run() {postInvalidate();tickHandler.postDelayed(tickRunnable, 1000);}};protected void onDraw(Canvas canvas) {super.onDraw(canvas);Calendar cal = Calendar.getInstance(TimeZone.getTimeZone(sTimeZoneString));int hour = cal.get(Calendar.HOUR);int minute = cal.get(Calendar.MINUTE);int second = cal.get(Calendar.SECOND);float hourRotate = hour * 30.0f + minute / 60.0f * 30.0f;float minuteRotate = minute * 6.0f;float secondRotate = second * 6.0f;boolean scaled = false;if (availableWidth < mWidth || availableHeight < mHeigh) {scaled = true;float scale = Math.min((float) availableWidth / (float) mWidth,(float) availableHeight / (float) mHeigh);canvas.save();canvas.scale(scale, scale, centerX, centerY);}bmdDial.setBounds(centerX - (mWidth / 2), centerY - (mHeigh / 2),centerX + (mWidth / 2), centerY + (mHeigh / 2));bmdDial.draw(canvas);mTempWidth = bmdHour.getIntrinsicWidth();mTempHeigh = bmdHour.getIntrinsicHeight();canvas.save();canvas.rotate(hourRotate, centerX, centerY);bmdHour.setBounds(centerX - (mTempWidth / 2), centerY- (mTempHeigh / 2), centerX + (mTempWidth / 2), centerY+ (mTempHeigh / 2));bmdHour.draw(canvas);canvas.restore();mTempWidth = bmdMinute.getIntrinsicWidth();mTempHeigh = bmdMinute.getIntrinsicHeight();canvas.save();canvas.rotate(minuteRotate, centerX, centerY);bmdMinute.setBounds(centerX - (mTempWidth / 2), centerY- (mTempHeigh / 2), centerX + (mTempWidth / 2), centerY+ (mTempHeigh / 2));bmdMinute.draw(canvas);canvas.restore();mTempWidth = bmdSecond.getIntrinsicWidth();mTempHeigh = bmdSecond.getIntrinsicHeight();canvas.rotate(secondRotate, centerX, centerY);bmdSecond.setBounds(centerX - (mTempWidth / 2), centerY- (mTempHeigh / 2), centerX + (mTempWidth / 2), centerY+ (mTempHeigh / 2));bmdSecond.draw(canvas);if (scaled) {canvas.restore();}}
}

                        主Activity：

package com.kiritor.mymodelclock;import android.app.Activity;
import android.os.Bundle;/*** Created by Kiritor on 13-5-30.*/
public class MainActivity extends Activity {public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}
}

                        好了一个简单的模拟时钟就完成了，不过通过观察运行效果可以看出的是，笔者对

                时针、分针、秒针图片的设计不是太美观，看的不是太清楚，体验略差。不过这不是重点

                读者可以自己去设计一下那4张图片，从而做出不同的效果!

                        这里本实例使用Android Studio做的，完整项目源码就不上传了!Over！
