Create an analog clock widget showing the time according to different time zones

In fact, I have to make an analog clock widget showing world time after selecting a specific time zone. I created an analog clock with the ability to select time zones. I want the same watch with an updated time zone to appear as a widget. I don’t understand how to display only the clock as a widget.

My code is:

package nEx.Software.Tutorials.Widgets.AnalogClock; import java.util.Calendar; import java.util.Date; import java.util.GregorianCalendar; import java.util.TimeZone; import java.util.Timer; import java.util.TimerTask; //import nEx.Software.Tutorials.Widgets.AnalogClock.main.CustomClock; //import nEx.Software.Tutorials.Widgets.AnalogClock.main.MyTime; import android.app.Activity; import android.content.Context; import android.content.Intent; import android.graphics.Canvas; import android.graphics.Paint; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.view.View; import android.view.ViewGroup; import android.widget.FrameLayout; import android.widget.LinearLayout; import android.widget.RadioButton; import android.widget.RadioGroup; import android.widget.TextView; public class Info 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; @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; } private void updateTime(String str) { // TODO Auto-generated method stub if (timer != null) { timer.cancel(); timer = null; } timer = new Timer(); //digital clock 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("GMT"); } if (rb2.isChecked() == true) { updateTime("EST"); } if (rb3.isChecked() == true) { updateTime("MST"); } } 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) { } } 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() { @Override 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)); } }; public class CustomClock extends View { private final float x; private final float y; private final int r = 70; 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; } @Override 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); } } //} // } }

Application widgets are pretty limited to a few views called "remote views." even they are not so flexible. The reason for this decision is probably security. You will need to find a solution to this problem, since you cannot create your own customized view as an application. here is a list of all available remote views: http://developer.android.com/guide/topics/appwidgets/index.html#CreatingLayout

You can use your analog clock if you want.
