Hello everyone!

I have a problem using the CircularSeekBar that is strange for me: Everything works fine and looks great, until I change the text of the textView in the same relative layout.

I call this method in onProgressChange: private void updateStatus(int progress) { TextView tv = (TextView) findViewById(R.id.status_seekbar_noise); int hz = (int) calcHzFromPercent(progress); tv.setText(hz+" Hz"); }

If I remove the tv.setText()-method, everything works fine. If I try to use the line, the handle of the seekbar jumps back to 0 degrees and then back to where it should be. This flattering happens all the time. So what is wrong with my code? Or is it the code in the CircularSeekBar-Class.

If anyone knows the solution please tell me.

Best regards and thanks for the great code!

It would be very nice to have some license for that library. Because for now no commercial product can use it (at least legally) - thus less developers are involved in solving bugs.

1. setProgress() method was not calculating new Percent correctly now fixed .
2. Added hideSeekBar() method to hide seekbar.
3. Added ShowSeekBar() method to show seekbar; By Default its visible.

I did some really small changes on CircularSeekBar and it makes it more responsive.

Changing the adjustmentFactor and improving the way to compute the poisition of the marker on the circle

My code is...

public class FragmentCadastro1 extends Fragment{

CircularSeekBar circularSeekbar;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_cadastro_1, container,
            false);
    circularSeekbar = new CircularSeekBar(getActivity());
    circularSeekbar.setMaxProgress(100);
    circularSeekbar.setProgress(100);
    circularSeekbar.invalidate();

    circularSeekbar.setSeekBarChangeListener(new OnSeekChangeListener() {

        @Override
        public void onProgressChange(CircularSeekBar view, int newProgress) {
            Log.i("Welcome", "Progress:" + view.getProgress() + "/" + view.getMaxProgress());
        }
    });



    return view;
}

does not come in LogCat no events...why ? Context ?

hi all, i found a problem about the max angle...if you print the angle inside the onSeekChangeListener like below:

mSeekBar.setSeekBarChangeListener(new CircularSeekBar.OnSeekChangeListener() { @Override public void onProgressChange(CircularSeekBar view, int newProgress) { Log.d("onProgressChange", view.getAngle()); } });

you will find that the angle reaches from 0 degree to 360 degree, which is incorrect and should be 359 degree instead.

hope my finding is useful. cheers!

I can use circularSeekBar in a fragment which is displayed in via an activity fine. (The first fragment displayed.) I have a problem when it is not the first fragment that is displayed. E.g. If I had another Fragment displaying and I replace it with the one that contains the circularSeekBar. The circularSeekBar is display but not correctly. It appears it is not fully updated. I can touch it and then it corrects itself. What can I do to correct this. It appears it needs some type of refresh.

Hi,

I have to create circular seek bar with drawable image inside circle. While moving the image. seek bar progress is to be set. But image is hiding because it is drawn inside rectangle. How can i draw circle by giving some distance between rectangle border?

getHeight() and getWidth does not return height and width of view if used in onMeasure; they return 0.

Height and width are assigned in the drawing phase which, in essence occurs way after onMeasure is called.

There is a simple fix for this:

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); width = View.MeasureSpec.getSize(widthMeasureSpec); height = View.MeasureSpec.getSize(heightMeasureSpec);

    int size = (width > height) ? height : width; // Choose the smaller
    // between width and
    // height to make a
    // square

    cx = width / 2; // Center X for circle
    cy = height / 2; // Center Y for circle
    outerRadius = size / 2; // Radius of the outer circle

    innerRadius = outerRadius - barWidth; // Radius of the inner circle

    left = cx - outerRadius; // Calculate left bound of our rect
    right = cx + outerRadius;// Calculate right bound of our rect
    top = cy - outerRadius;// Calculate top bound of our rect
    bottom = cy + outerRadius;// Calculate bottom bound of our rect

    startPointX = cx; // 12 O'clock X coordinate
    startPointY = cy - outerRadius;// 12 O'clock Y coordinate
    markPointX = startPointX;// Initial locatino of the marker X coordinate
    markPointY = startPointY;// Initial locatino of the marker Y coordinate

    rect.set(left, top, right, bottom); // assign size to rect
}

This will work in any layout, activity or fragment.

Best wishes, and great code. +1
