Set time with custom android AnalogClock from its original class

Question

I want to make a custom AnalogClock class using source code of AnalogClock by Android Open Source Project that is available in the internet.

I want to make the clock

Answer 1

//Here you can set the size of your clock
int availableWidth = 70;
int availableHeight = 70;

This is where you can change the size of the View.

Answer 2

Working custom MyAnalogClock with setTime() method.

After spending some time I finally managed to solve the problem. I hope it will be useful for someone. You can set time simply by calling setTime(hours, minutes, seconds) method.

import android.content.Context;
import android.content.res.Resources;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.drawable.Drawable;
import android.text.format.Time;
import android.util.AttributeSet;
import android.view.View;
import android.widget.RemoteViews.RemoteView;

/**
 * This widget display an analogic clock with two hands for hours and
 * minutes.
 */
@RemoteView
public class MyAnalogClock extends View {

    private Drawable mHourHand;
    private Drawable mMinuteHand;
    private Drawable mSecondHand;
    private Drawable mDial;

    private int mDialWidth;
    private int mDialHeight;

    private float mSeconds;
    private float mMinutes;
    private float mHour;

    Context mContext;

    public MyAnalogClock(Context context) {
        super(context);
    }

    public MyAnalogClock(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public MyAnalogClock(Context context, AttributeSet attrs,
                       int defStyle) {
        super(context, attrs, defStyle);
        Resources r = context.getResources();
        TypedArray a =
                context.obtainStyledAttributes(
                        attrs, R.styleable.AnalogClock, defStyle, 0);
        mContext=context;
       // mDial = a.getDrawable(com.android.internal.R.styleable.AnalogClock_dial);
       // if (mDial == null) {
            mDial = r.getDrawable(R.drawable.clock_dial);
       // }

      //  mHourHand = a.getDrawable(com.android.internal.R.styleable.AnalogClock_hand_hour);
      //  if (mHourHand == null) {
            mHourHand = r.getDrawable(R.drawable.clock_hour);
      //  }

     //   mMinuteHand = a.getDrawable(com.android.internal.R.styleable.AnalogClock_hand_minute);
     //   if (mMinuteHand == null) {
            mMinuteHand = r.getDrawable(R.drawable.clock_minute);
            mSecondHand = r.getDrawable(R.drawable.clockgoog_minute);
     //   }

        mDialWidth = mDial.getIntrinsicWidth();
        mDialHeight = mDial.getIntrinsicHeight();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthSize =  MeasureSpec.getSize(widthMeasureSpec);
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightSize =  MeasureSpec.getSize(heightMeasureSpec);

        float hScale = 1.0f;
        float vScale = 1.0f;

        if (widthMode != MeasureSpec.UNSPECIFIED && widthSize < mDialWidth) {
            hScale = (float) widthSize / (float) mDialWidth;
        }

        if (heightMode != MeasureSpec.UNSPECIFIED && heightSize < mDialHeight) {
            vScale = (float )heightSize / (float) mDialHeight;
        }

        float scale = Math.min(hScale, vScale);

        setMeasuredDimension(resolveSize((int) (mDialWidth * scale), widthMeasureSpec),
                resolveSize((int) (mDialHeight * scale), heightMeasureSpec));
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        //Here you can set the size of your clock
        int availableWidth = 70;
        int availableHeight = 70;

        //Actual size
        int x = availableWidth / 2;
        int y = availableHeight / 2;

        final Drawable dial = mDial;
        int w = dial.getIntrinsicWidth();
        int h = dial.getIntrinsicHeight();

        boolean scaled = false;

        if (availableWidth < w || availableHeight < h) {
            scaled = true;
            float scale = Math.min((float) availableWidth / (float) w,
                                   (float) availableHeight / (float) h);
            canvas.save();
            canvas.scale(scale, scale, x, y);
        }

        dial.setBounds(x - (w / 2), y - (h / 2), x + (w / 2), y + (h / 2));
        dial.draw(canvas);

        canvas.save();
        canvas.rotate(mHour / 12.0f * 360.0f, x, y);
        w = mHourHand.getIntrinsicWidth();
        h = mHourHand.getIntrinsicHeight();
        mHourHand.setBounds(x - (w / 2), y - (h / 2), x + (w / 2), y + (h / 2));
        mHourHand.draw(canvas);
        canvas.restore();

        canvas.save();
        canvas.rotate(mMinutes / 60.0f * 360.0f, x, y);
        w = mMinuteHand.getIntrinsicWidth();
        h = mMinuteHand.getIntrinsicHeight();
        mMinuteHand.setBounds(x - (w / 2), y - (h / 2), x + (w / 2), y + (h / 2));
        mMinuteHand.draw(canvas);
        canvas.restore();

        canvas.save();
        canvas.rotate(mSeconds, x, y);
        w = mSecondHand.getIntrinsicWidth();
        h = mSecondHand.getIntrinsicHeight();
        mSecondHand.setBounds(x - (w / 2), y - (h / 2), x + (w / 2), y + (h / 2));
        mSecondHand.draw(canvas);
        canvas.restore();
        if (scaled) {
            canvas.restore();
        }
    }

    public void setTime(int hours, int minutes, int seconds)
    {
        mSeconds = 6.0f*seconds;
        mMinutes = minutes + seconds / 60.0f;
        mHour = hours + mMinutes / 60.0f;
    }
}

You should also put 4 drawable files in the drawable folder and create (or update) the attrs file in values folder with the following code:

<?xml version="1.0" encoding="UTF-8"?>
<resources>
    <declare-styleable name="AnalogClock">
        <attr name="dial" format="reference"/>
        <attr name="hand_hour" format="reference"/>
        <attr name="hand_minute" format="reference"/>
    </declare-styleable>
    </resources>
