Android programmation - dessin horloge analogique

Salut les Amis j'ai fait la solution à mon problème......
Je tiens à partager la solution avec les types d'u...

public class TimeShow extends Activity implements RadioGroup.OnCheckedChangeListener{
Context context;
TextView tv;
RadioButton rb1,rb2,rb3;
RadioGroup r1;
FrameLayout fl1;
LinearLayout l1;
Timer timer;
Date result;
ViewGroup.LayoutParams lp1;
Drawable bck;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    context=this;
    tv = (TextView)findViewById(R.id.TextView01);
    r1=(RadioGroup)findViewById(R.id.RadioGroup01);
    rb1=(RadioButton)findViewById(R.id.RadioButton01);
    rb2=(RadioButton)findViewById(R.id.RadioButton02);
    rb3=(RadioButton)findViewById(R.id.RadioButton03);
    fl1=(FrameLayout)findViewById(R.id.FrameLayout01);
    bck=this.getResources().getDrawable(R.drawable.clockface);
    fl1.setBackgroundDrawable(bck);
    lp1=fl1.getLayoutParams();
    r1.setOnCheckedChangeListener(this);
    result=null;
}

Suivant est une méthode appelée updateTime comme suit:

private void updateTime(String str) {
//TODO Auto-generated method stub
if(timer!=null)
{
timer.cancel();
timer=null;
}
timer = new Timer();
MyTime mt=new MyTime(this,str);
timer.schedule(mt, 1, 1000);
}
public void onCheckedChanged(RadioGroup group, int checkedId) {
//TODO Auto-generated method stub
if(rb1.isChecked() == true)
updateTime("Asia/Kolkata");
if(rb2.isChecked() == true)
updateTime("Etc/GMT-6");
if(rb3.isChecked() == true)
updateTime("Asia/Karachi");
}
public class MyTime extends TimerTask {
String tz;
public MyTime(Context context,String str) {
tz=str;
}
@Override
public void run() {
//TODO Auto-generated method stub
try{
Date date=new Date();
date=getDateInTimeZone(date, tz);
//System.out.println(date.toLocaleString());
result=date;
handler.sendEmptyMessage(0);
}catch(Exception e){
e.printStackTrace();
}
}
private Date getDateInTimeZone(Date currentDate, String timeZoneId) {
TimeZone tz = TimeZone.getTimeZone(timeZoneId);
Calendar mbCal = new GregorianCalendar(tz);
mbCal.setTimeInMillis(currentDate.getTime());
Calendar cal = Calendar.getInstance();
cal.set(Calendar.YEAR, mbCal.get(Calendar.YEAR));
cal.set(Calendar.MONTH, mbCal.get(Calendar.MONTH));
cal.set(Calendar.DAY_OF_MONTH, mbCal.get(Calendar.DAY_OF_MONTH));
cal.set(Calendar.HOUR_OF_DAY, mbCal.get(Calendar.HOUR_OF_DAY));
cal.set(Calendar.MINUTE, mbCal.get(Calendar.MINUTE));
cal.set(Calendar.SECOND, mbCal.get(Calendar.SECOND));
cal.set(Calendar.MILLISECOND, mbCal.get(Calendar.MILLISECOND));
return cal.getTime();
}
}
Handler handler=new Handler(){
public void handleMessage(Message msg) {
tv.setText(result.toLocaleString());
//System.out.println(result.getHours()+" "+result.getMinutes());
fl1.removeAllViews();
fl1.addView(new CustomClock(context, lp1.height/2, lp1.width/2, result));
}
};
}

Et une classe CustomClock qui s'étend de la vue:

public class CustomClock extends View {
private final float x;
private final float y;
private final int r=45;
private final Date date;
private final Paint mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
public CustomClock(Context context, float x, float y, Date date) {
super(context);
this.x = x;
this.y = y;
this.date=date;        
}
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
//canvas.drawCircle(x, y, r, mPaint);
float sec=(float)date.getSeconds();
float min=(float)date.getMinutes();
float hour=(float)date.getHours()+min/60.0f;
mPaint.setColor(0xFFFF0000);
canvas.drawLine(x, y, (float)(x+(r-15)*Math.cos(Math.toRadians((hour / 12.0f * 360.0f)-90f))), (float)(y+(r-10)*Math.sin(Math.toRadians((hour / 12.0f * 360.0f)-90f))), mPaint);
canvas.save();
mPaint.setColor(0xFF0000FF);
canvas.drawLine(x, y, (float)(x+r*Math.cos(Math.toRadians((min / 60.0f * 360.0f)-90f))), (float)(y+r*Math.sin(Math.toRadians((min / 60.0f * 360.0f)-90f))), mPaint);
canvas.save();
mPaint.setColor(0xFFA2BC13);
canvas.drawLine(x, y, (float)(x+(r+10)*Math.cos(Math.toRadians((sec / 60.0f * 360.0f)-90f))), (float)(y+(r+15)*Math.sin(Math.toRadians((sec / 60.0f * 360.0f)-90f))), mPaint);
}
}
