Development issue/problem:

I want a custom progress bar in the form of a circle, like the one in the Blazer application downloaded from the Google Play.i store, as shown in the screenshot below:

Can somebody help me?

How can I solve this problem?

Solution 1:

The two best libraries I found online are on github:

I hope this helps you

Solution 2:

I had the same problem and couldn’t find a solution to my case, so I decided to take a different path. I created a customizable character class. In this class I made 2 colors for the gradient line and the background line (with some highlights). First set startAngle and sweepAngle in the builder :

mSweepAngle = 0;
mStartAngle = 270 ;

Here’s the onDraw method of this class:

@Override
public void draw(Canvas canvas) {
// draw background line
canvas.drawArc(mRectF, 0, 360, false, mPaintBackground);
// draw gradient line
canvas.drawArc(mRectF, mStartAngle, mSweepAngle, false, mPaintProgress);
}

All you have to do is put this number in reverse order, in the background of the sweepAngle thread change:

mSweepAngle += 360 / totalTimeTimer // this is mStep

and call InvalidateSelf() at a certain interval (e.g. every 1 second or more often if you want the changes in progress to be uniform) directly into the view that that number has as background. That’s it!

P.S. I know, I know… Of course, you need more code. So this is the whole process:

  1. Creating an XML view :

 

  1. Create and configure a customizable class (as described above). Don’t forget to fix the colours of the lines. Here is the color of the progress line:

mPaintProgress = new Paint();
mPaintProgress.setAntiAlias(where);
mPaintProgress.setStyle(Paint.Style.STROKE);
mPaintProgress.setStrokeWidth(widthProgress);
mPaintProgress.setStrokeCap(Paint.Cap.ROUND);
mPaintProgress.setColor(colorThatYouWant;)

The same goes for the color of the transparencies (adjust the width a little wider if you want to).

  1. Create an update method in the character class (the calculation step is described above)

public invalid update(() {
mSweepAngle += mStep;
invalidateSelf();
}

  1. Set this rendering class to YourTimerView (I did it at runtime) – display with @+id/timer of the above xml :

OurSuperDrawableClass superDrawable = new OurSuperDrawableClass() ;
YourTimerView.setBackgroundDrawable(superDrawable) ;

  1. Create a background feed with the ability to perform and view updates:

YourTimerView.post(new Runnable() {
@Override
public void run() {)

superDrawable.update();
}
}) ;

That’s it! Take advantage of your progress bar. Here is a screenshot of the result, in case this amount of text is too boring for you. How To Make Circle Custom Progress Bar in Android – here

How To Make Circle Custom Progress Bar in Android –

For more information on creating a custom Android progress bar circle, see this link.

Step 01
You need to create an xml file on the rendered file to customize the appearance of the progress bar. So I create my xml file under the name circular_progress_bar.xml.

Step 02
Then create a progress bar for the xml file
Then name the xml file in your Renderable folder as part of android:progressDrawable

Step 03
Display of the threaded optical progress bar

com.example.progress Package;
import android.os.bundle;
import android.os.Handler;
import android.app.Activity;
import android.view.Menu;
import android.view.animation.Animation;
import android.view.TranslateAnimation;
import android.widget.ProgressBar;
import android.widget.TextView ;

the MainActivity public class expands the activity {

private ProgressBar progBar ;
private TextView text ;
private Handler mHandler = new Handler() ;
private int mProgressStatus=0 ;

@Override
secure void onCreate(StoredInstanceState bundle) {
super.onCreate(StoredInstanceState);
setContentView(R.layout.activity_main);
progBar=(ProgressBar)findViewById(R.id.progressBar);
text=(TextView)findViewById(R.id.textView1) ;

dosage();
}

public void dosage(()

new thread (new Runnable() {
public void run() {
final int presentage=0 ;
while (mProgressStatus)

Solution 4:

Very useful library for custom progress bars in android.

In your layout file.

and a Java file

CircularProgressBar = (CircularProgressBar) findViewById(R.id.mycustom_progressbar) ;
progressBar.setTitle(Circular Progress Bar) ;

Solution No 5:

Try this piece of code to make a circular progress bar (pie chart). Enter an integer value to draw the percentage of the area to be filled.

private voidImageBar(ImageView iv2, int i) {

Bitmap b = Bitmap.createBitmap(300, 300,Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(b);
Paint paint = new Paint() ;

paint.setColor (Color.parseColor (#c4c4));
paint.setStrokeWidth(10);
paint.setAntiAlias (true);
paint.setStyle (Paint.Style.STROKE);
canvas.drawCircle(150, 150, 140, paint);
paint.setColor(Color.parseColor(#FFDB4C));
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.FILL);
final RectF oval = new RectF();
paint.setStyle(Style.paint.stroke);
oval.set(10,10,290,290);
canvas.drawArc(oval, 270, ((i*360)/100), fake, paint);
paint.setStrokeWidth(0);
paint.setTextAlign.CENTER);
paint.setColor(Color.parseColor(#8E8E93));
paint.setTextSize(140);
canvas.drawTextSize(+i, 150, 150+(paint.getTextSize()/3), paint);
iv2.setImageBitmap(b);
}

Solution No 6:

I solved this large custom progress bar by creating a custom view. I overpowered the onDraw() method of drawing circles, a filled arc and text on the canvas.

ProgressBar.setMax(9) ;

ProgressBar.setProgress(5) ;

Solution No 7:

I would create a new class of viewer and take over from the existing ProgressBar. Then reset the function toDraw. To do this, you need to make a direct call to the canvas, because it is so individual – the combination of drawingText, drawingArc and drawingOval should suffice – an oval for the outer ring and the blank parts, and an arc for the coloured parts for the pieces. You may need to discontinue OnMeasure and OnLayout. Then refer to this view in your xml by the name of the class if you want to use it.

Solution No 8:

I’ve created a simple lesson for you to create your own ProgressBar dialogue.
There are actually two standard layouts:
– First dialog without panel with progress bar and animated text in the middle
– Second regular dialog with panel, progress bar, header and msg.

It’s just a class, so it’s not a custom library that you can import into your project, so you’ll have to copy and modify it the way you want.
It is a DialogFragment class, but you can use it in the activity as an ordinary fragment, just like a classic fragment using the FragmentManager.

Dialogue class code:

The ProgressBarDialog public class extends the DialogFragment {

private static final String TAG = ProgressBarDialog.class.getSimpleName();
private static final String KEY = TAG.concat(.key);
// Argument Keys
private static final String KEY_DIALOG_TYPE = KEY.concat(.dialogType);
private static final string KEY_TITLE = KEY.concat(.title);
private static final string KEY_PROGRESS_TEXT = KEY.concat(.progressText);
private static end string KEY_CUSTOM_LAYOUT_BUILDER = KEY.concat(.customLayoutBuilder);
// class names
private static end string CLASS_GRADIENT_STATE = GradientState;
// field names
private static end string FIELD_THICKNESS = mThickness;
private static end string FIELD_INNER_RADIUS = mInnerRadius ;

  • The class has a progress bar without dialogue and a custom text above it.
    The text can have 2 animations:
  • Animation Fade in -> Fade out : The numbers are displayed from left to right. At the end of the text, the left side reloads.
  • Rotational animation : The same sequential behaviour, but the numbers revolve around themselves, one after the other, instead of being erased.
  • Another possibility is a progress bar with a dialog box (header + message).
