How to Create a circular progressbar in Android wh

Question

I am trying to create a rounded progressbar. This is what I want to achieve

There is a grey color background ring. On top of it, a blue color progressbar appears which moves in a circular path from 0 to 360 in 60 or whatever amount of seconds.

Here is my example code.

<ProgressBar
            android:id="@+id/ProgressBar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            style="?android:attr/progressBarStyleLarge"
            android:indeterminateDrawable="@drawable/progressBarBG"
            android:progress="50"
            />

To do this, in the drawable "progressBarBG", I am creating a layerlist and inside that layer list I am giving two items as shown.

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
    <shape
            android:shape="ring"
            android:innerRadius="64dp"
            android:thickness="8dp"
            android:useLevel="false">

        <solid android:color="@color/grey" />
    </shape>
</item>

<item android:id="@android:id/progress">
    <clip>
        <shape
                android:shape="ring"
                android:innerRadius="64dp"
                android:thickness="8dp"
                android:useLevel="false">

            <solid android:color="@color/blue" />
        </shape>
    </clip>
</item>

Now, the first grey ring is generated fine. The blue ring however starts from the left of the drawable and goes to the right just like how a linear progressbar works. This is how it shows at 50% progress with the red color arrow showing direction.

I want to move the blue progressbar in circular path as expected.

I have written detailed example on circular progress bar in android here on my blog demonuts.com. You can also fond full source code and explanation there.

Here's how I made circular progressbar with percentage inside circle in pure code without any library.

first create a drawable file called circular.xml

<?xml version="1.0" encoding="utf-8"?>

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/secondaryProgress">
        <shape
            android:innerRadiusRatio="6"
            android:shape="ring"
            android:thicknessRatio="20.0"
            android:useLevel="true">


            <gradient
                android:centerColor="#999999"
                android:endColor="#999999"
                android:startColor="#999999"
                android:type="sweep" />
        </shape>
    </item>

    <item android:id="@android:id/progress">
        <rotate
            android:fromDegrees="270"
            android:pivotX="50%"
            android:pivotY="50%"
            android:toDegrees="270">

            <shape
                android:innerRadiusRatio="6"
                android:shape="ring"
                android:thicknessRatio="20.0"
                android:useLevel="true">


                <rotate
                    android:fromDegrees="0"
                    android:pivotX="50%"
                    android:pivotY="50%"
                    android:toDegrees="360" />

                <gradient
                    android:centerColor="#00FF00"
                    android:endColor="#00FF00"
                    android:startColor="#00FF00"
                    android:type="sweep" />

            </shape>
        </rotate>
    </item>
</layer-list>

Now in your activity_main.xml add following:

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/dialog"
    tools:context="com.example.parsaniahardik.progressanimation.MainActivity">

    <ProgressBar

        android:id="@+id/circularProgressbar"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:indeterminate="false"
        android:max="100"
        android:progress="50"
        android:layout_centerInParent="true"
        android:progressDrawable="@drawable/circular"
        android:secondaryProgress="100"
        />

    <ImageView
        android:layout_width="90dp"
        android:layout_height="90dp"
        android:background="@drawable/whitecircle"
        android:layout_centerInParent="true"/>

    <TextView
        android:id="@+id/tv"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:gravity="center"
        android:text="25%"
        android:layout_centerInParent="true"
        android:textColor="@color/colorPrimaryDark"
        android:textSize="20sp" />

</RelativeLayout>

In activity_main.xml I have used one circular image with white background to show white background around percentage. Here is the image:

You can change color of this image to set custom color around percentage text.

Now finally add following code to MainActivity.java :

import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.animation.DecelerateInterpolator;
import android.widget.ProgressBar;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    int pStatus = 0;
    private Handler handler = new Handler();
    TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Resources res = getResources();
        Drawable drawable = res.getDrawable(R.drawable.circular);
        final ProgressBar mProgress = (ProgressBar) findViewById(R.id.circularProgressbar);
        mProgress.setProgress(0);   // Main Progress
        mProgress.setSecondaryProgress(100); // Secondary Progress
        mProgress.setMax(100); // Maximum Progress
        mProgress.setProgressDrawable(drawable);

      /*  ObjectAnimator animation = ObjectAnimator.ofInt(mProgress, "progress", 0, 100);
        animation.setDuration(50000);
        animation.setInterpolator(new DecelerateInterpolator());
        animation.start();*/

        tv = (TextView) findViewById(R.id.tv);
        new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                while (pStatus < 100) {
                    pStatus += 1;

                    handler.post(new Runnable() {

                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            mProgress.setProgress(pStatus);
                            tv.setText(pStatus + "%");

                        }
                    });
                    try {
                        // Sleep for 200 milliseconds.
                        // Just to display the progress slowly
                        Thread.sleep(8); //thread will take approx 1.5 seconds to finish
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        }).start();
    }
}

Answer 2

try this method to create a bitmap and set it to image view.

private void circularImageBar(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("#c4c4c4"));
        paint.setStrokeWidth(10);
        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(Paint.Style.STROKE);
        oval.set(10,10,290,290);

        canvas.drawArc(oval, 270, ((i*360)/100), false, paint);
        paint.setStrokeWidth(0);    
        paint.setTextAlign(Align.CENTER);
        paint.setColor(Color.parseColor("#8E8E93")); 
        paint.setTextSize(140);

        canvas.drawText(""+i, 150, 150+(paint.getTextSize()/3), paint); 

        iv2.setImageBitmap(b);
}

I have done with easy way:

Please check screen shot for the same.

CustomProgressBarActivity.java:

public class CustomProgressBarActivity extends AppCompatActivity {

    private TextView txtProgress;
    private ProgressBar progressBar;
    private int pStatus = 0;
    private Handler handler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_custom_progressbar);

        txtProgress = (TextView) findViewById(R.id.txtProgress);
        progressBar = (ProgressBar) findViewById(R.id.progressBar);

        new Thread(new Runnable() {
            @Override
            public void run() {
                while (pStatus <= 100) {
                    handler.post(new Runnable() {
                        @Override
                        public void run() {
                            progressBar.setProgress(pStatus);
                            txtProgress.setText(pStatus + " %");
                        }
                    });
                    try {
                        Thread.sleep(100);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    pStatus++;
                }
            }
        }).start();

    }
}

Hope this will help you.

Answer 4

I realized a Open Source library on GitHub CircularProgressBar that does exactly what you want the simplest way possible:

USAGE

To make a circular ProgressBar add CircularProgressBar in your layout XML and add CircularProgressBar library in your projector or you can also grab it via Gradle:

compile 'com.mikhaellopez:circularprogressbar:1.0.0'

XML

<com.mikhaellopez.circularprogressbar.CircularProgressBar
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:background_progressbar_color="#FFCDD2"
    app:background_progressbar_width="5dp"
    app:progressbar_color="#F44336"
    app:progressbar_width="10dp" />

You must use the following properties in your XML to change your CircularProgressBar.

Properties:

• app:progress (integer) >> default 0
• app:progressbar_color (color) >> default BLACK
• app:background_progressbar_color (color) >> default GRAY
• app:progressbar_width (dimension) >> default 7dp
• app:background_progressbar_width (dimension) >> default 3dp

JAVA

CircularProgressBar circularProgressBar = (CircularProgressBar)findViewById(R.id.yourCircularProgressbar);
circularProgressBar.setColor(ContextCompat.getColor(this, R.color.progressBarColor));
circularProgressBar.setBackgroundColor(ContextCompat.getColor(this, R.color.backgroundProgressBarColor));
circularProgressBar.setProgressBarWidth(getResources().getDimension(R.dimen.progressBarWidth));
circularProgressBar.setBackgroundProgressBarWidth(getResources().getDimension(R.dimen.backgroundProgressBarWidth));
int animationDuration = 2500; // 2500ms = 2,5s
circularProgressBar.setProgressWithAnimation(65, animationDuration); // Default duration = 1500ms
