I want to make vertical progress bar with dividers on it. however , i am unable to do so.
This code works fine for horizontal progress bar but when i want to make it work like vertical progress bar it doesn't work.
Any help appreciated.
class ProgressDrawable extends Drawable {
private static final int NUM_RECTS = 10;
Paint mPaint = new Paint();
#Override
protected boolean onLevelChange(int level) {
invalidateSelf();
return true;
}
#Override
public void draw(Canvas canvas) {
int level = getLevel();
Rect b = getBounds();
float height = b.height();
for (int i = 0; i < NUM_RECTS; i++) {
float bottom = height * i / NUM_RECTS;
float top = bottom + 0.9f * height / NUM_RECTS;
mPaint.setColor((i + 1) * 10000 / NUM_RECTS <= level? 0xff888888 : 0xffbbbbbb);
// canvas.drawRect(left, b.top, right, b.bottom, mPaint);
//canvas.drawRect(left, b.top, right, b.bottom, mPaint);
canvas.drawRect(bottom, b.bottom, top, b.top, mPaint);
}
}
#Override
public void setAlpha(int alpha) {
}
#Override
public void setColorFilter(ColorFilter cf) {
}
#Override
public int getOpacity() {
return PixelFormat.TRANSLUCENT;
}
}
I know its late , but if someone want looking for it ,you can see here
private static final int NUM_RECTS = 10;
Paint mPaint = new Paint();
#Override
public void draw(Canvas canvas) {
// TODO Auto-generated method stub
int level = getLevel();// It will give the level of progress(0 to 10,000)
Rect b = getBounds();
float height = b.height();
float width=b.width();
float x=40;
float y=0;
for (int i =0; i<NUM_RECTS; i++) {
if((i+1)*10000/NUM_RECTS>level)
{
mPaint.setColor(Color.GRAY);
}else{
mPaint.setColor(Color.GREEN);
}
canvas.drawRect(0,height-x,width,height-y, mPaint);
//canvas.drawCircle(width/2,height-y,30, mPaint);
x=x+50;
y=y+50;
}
}

I wanted to show profile status using a Progress bar just like Linkedin, I searched everywhere but didn't get any reference related to that.
My code:
public class ProgressDrawable extends Drawable {
private static final int NUM_SEGMENTS = 5;
private final int mForeground;
private final int mBackground;
private final Paint mPaint = new Paint();
private final RectF mSegment = new RectF();
public ProgressDrawable(int fgColor, int bgColor) {
mForeground = fgColor;
mBackground = bgColor;
}
#Override
protected boolean onLevelChange(int level) {
invalidateSelf();
return true;
}
#Override
public void draw(Canvas canvas) {
float level = getLevel() / 10000f;
Rect b = getBounds();
float gapWidth = b.height() / 10f;
float segmentWidth = (b.width() - (NUM_SEGMENTS - 1) * gapWidth) / NUM_SEGMENTS;
mSegment.set(0, 0, segmentWidth, b.height());
mPaint.setColor(mForeground);
for (int i = 0; i < NUM_SEGMENTS; i++) {
float loLevel = i / (float) NUM_SEGMENTS;
float hiLevel = (i + 1) / (float) NUM_SEGMENTS;
if (loLevel <= level && level <= hiLevel) {
float middle = mSegment.left + NUM_SEGMENTS * segmentWidth * (level - loLevel);
canvas.drawRect(mSegment.left, mSegment.top, middle, mSegment.bottom, mPaint);
mPaint.setColor(mBackground);
canvas.drawRect(middle, mSegment.top, mSegment.right, mSegment.bottom, mPaint);
} else {
canvas.drawRect(mSegment, mPaint);
}
mSegment.offset(mSegment.width() + gapWidth, 0);
}

In this code, all the blocks have same color, but as per requirement, all block colors should be different.

You can use ImageView instead of ImageButton
Have You tried android:background="#null" ?
I'm new to Fresco library and trying to show circle Progressbar when loading image from uri into DraweeView. Now I'm using default progressbar as below:
GenericDraweeHierarchyBuilder builder = new GenericDraweeHierarchyBuilder(getResources());
GenericDraweeHierarchy hierarchy = builder.setFadeDuration(fadeInTime).build();
hierarchy.setProgressBarImage(new ProgressBarDrawable());
thumbnailImageView.setHierarchy(hierarchy);
however, the ProgressBar is horizontal ProgressBar? Is there anyway to change it to circle?
After a lot of time to searching with Google, but I cant find any result. I decided to write my own CircleProgressDrawable. I just wanna share it for anyone who dont want to waste time as me.
public class CircleProgressDrawable extends ProgressBarDrawable {
private final Paint mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
private int mBackgroundColor = 0x80000000;
private int mColor = 0x800080FF;
private int mBarWidth = 20;
private int mLevel = 0;
private boolean mHideWhenZero = false;
private int radius = 50;
public CircleProgressDrawable() {
mPaint.setStyle(Paint.Style.STROKE);
mPaint.setStrokeWidth(10f);
}
public void setRadius(int radius) {
this.radius = radius;
}
/**

invalidateSelf();
}

}

if (mBackgroundColor != backgroundColor) {
mBackgroundColor = backgroundColor;
invalidateSelf();
}
}
/**

*/
public int getBackgroundColor() {
return mBackgroundColor;
}
/**

public void setBarWidth(int barWidth) {
if (mBarWidth != barWidth) {
mBarWidth = barWidth;
invalidateSelf();
}
}
/**

return mBarWidth;
}

Rect bounds = getBounds();
// find center point
int xpos = bounds.left + bounds.width() / 2;
int ypos = bounds.bottom - bounds.height() / 2;
RectF rectF = new RectF(xpos - radius, ypos - radius, xpos + radius, ypos + radius);
float degree = (float) level / (float) MAX_LEVEL * 360;
canvas.drawArc(rectF, 270, degree, false, mPaint);
LogUtils.e("level: " + level + ", degree: " + degree);
}
private void drawCircle(Canvas canvas, int color) {

I have a drawable that draws a progress bar using onLevelChange and calls draw() to make a line at bottom on canvas. How can I animate this line draw?
public class BorderProgressDrawable extends Drawable {
private static final int MAX_LEVEL = 10000;
private int mLevel = 0;
private Paint mPaint;
public BorderProgressDrawable(Context context) {
mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
mPaint.setColor(context.getResources().getColor(R.color.accent));
mPaint.setStrokeWidth((float) CommonMethods.dpToPx(context.getResources().getDisplayMetrics(), 4));
}
#Override
public void draw(final Canvas canvas) {
int width = canvas.getWidth();
int height = canvas.getHeight();
float visibleWidth = (((float) mLevel) / MAX_LEVEL) * width;
canvas.drawLine(0, height, visibleWidth, height, mPaint);
}
#Override
public void setAlpha(int i) {
mPaint.setAlpha(i);
}
#Override
public void setColorFilter(ColorFilter colorFilter) {
if (colorFilter != null) mPaint.setColorFilter(colorFilter);
}
#Override
public int getOpacity() {
return mPaint.getAlpha();
}
#Override
protected boolean onLevelChange(int level) {
mLevel = level;
return true;
}
}
can anyone help me create a progress bar with a styling like this one:
I know this is a common question and solution can be found, but I didnt saw a progress bar with the progress heigher than the other part.
So can someone help me create this?
So wih the help of #pskink's code, I've managed to create a solution for this issue. So here is the code and I hope it will help someone in the future!
public class ProgressDrawable extends Drawable {
private final int mForeground;
private final int mBackground;
private final Paint mPaint = new Paint();
private final RectF mSegment = new RectF();
public ProgressDrawable(int fgColor, int bgColor) {
mForeground = fgColor;
mBackground = bgColor;
}
#Override
protected boolean onLevelChange(int level) {
invalidateSelf();
return true;
}
#Override
public void draw(Canvas canvas) {
float level = getLevel() / 10000f;
Rect b = getBounds();
float gapWidth = b.height();
float segmentWidth = b.width();
mSegment.set(0, 0, segmentWidth * level, b.height());
mPaint.setColor(mForeground);
mSegment.set(0, b.height() / 3, segmentWidth, b.height() - (b.height() / 3));
mPaint.setColor(mBackground);
canvas.drawRect(mSegment.left, mSegment.top, mSegment.right, mSegment.bottom, mPaint);
}
#Override
public void setAlpha(int alpha) {
}
#Override
public int getIntrinsicHeight() {
return 3;
}
#Override
public void setColorFilter(ColorFilter cf) {
}
#Override
public int getOpacity() {
return PixelFormat.TRANSLUCENT;
}
}
and usage:
Drawable d = new ProgressDrawable(getActivity().getResources().getColor(R.color.toolbar_text_blue), getActivity().getResources().getColor(R.color.toolbar_text_blue));
dataProgress.setProgressDrawable(d);
dataProgress.setProgress(percent);
