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.
This question is related to
android
progress-bar
android-progressbar
progress-indicator
Here are my two solutions.
Short answer:
Instead of creating a layer-list
, I separated it into two files. One for ProgressBar
and one for its background.
This is the ProgressDrawable
file (@drawable folder): circular_progress_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="270"
android:toDegrees="270">
<shape
android:innerRadiusRatio="2.5"
android:shape="ring"
android:thickness="1dp"
android:useLevel="true"><!-- this line fixes the issue for lollipop api 21 -->
<gradient
android:angle="0"
android:endColor="#007DD6"
android:startColor="#007DD6"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>
And this is for its background
(@drawable folder): circle_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="ring"
android:innerRadiusRatio="2.5"
android:thickness="1dp"
android:useLevel="false">
<solid android:color="#CCC" />
</shape>
And at the end, inside the layout that you're working:
<ProgressBar
android:id="@+id/progressBar"
android:layout_width="200dp"
android:layout_height="200dp"
android:indeterminate="false"
android:progressDrawable="@drawable/circular_progress_bar"
android:background="@drawable/circle_shape"
style="?android:attr/progressBarStyleHorizontal"
android:max="100"
android:progress="65" />
Here's the result:
Long Answer:
Use a custom view which inherits the android.view.View
Here is the full project on github
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();
}
}

https://github.com/passsy/android-HoloCircularProgressBar is one example of a library that does this. As Tenfour04 stated, it will have to be somewhat custom, in that this is not supported directly out of the box. If this library doesn't behave as you wish, you can fork it and modify the details to make it work to your liking. If you implement something that others can then reuse, you could even submit a pull request to get that merged back in!
With the Material Components Library you can use the CircularProgressIndicator
:
Something like:
<com.google.android.material.progressindicator.CircularProgressIndicator
app:indicatorColor="@color/...."
app:trackColor="@color/...."
app:circularRadius="64dp"/>
You can use these attributes:
circularRadius
: defines the radius of the circular progress indicatortrackColor
: the color used for the progress track. If not defined, it will be set to the indicatorColor
and apply the android:disabledAlpha
from the theme.indicatorColor
: the single color used for the indicator in determinate/indeterminate mode. By default it uses theme primary colorUse progressIndicator.setProgressCompat((int) value, true);
to update the value in the indicator.
Note: it requires at least the version 1.3.0-alpha04
.
Good news is that now material design library supports determinate circular progress bars too:
<com.google.android.material.progressindicator.CircularProgressIndicator
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
For more info about this refer here.
Change
android:useLevel="false"
to
android:useLevel="true"
for second sahpe with id="@android:id/progress
hope it works
I realized a Open Source library on GitHub CircularProgressBar that does exactly what you want the simplest way possible:
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'
<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 0app:progressbar_color
(color) >> default BLACKapp:background_progressbar_color
(color) >> default GRAYapp:progressbar_width
(dimension) >> default 7dpapp:background_progressbar_width
(dimension) >> default 3dpCircularProgressBar 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
Fork or Download this library here >> https://github.com/lopspower/CircularProgressBar
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();
}
}
If you want to make horizontal progressbar, follow this link, it has many valuable examples with source code:
http://www.skholingua.com/android-basic/user-interface/form-widgets/progressbar
@Pedram, your old solution works actually fine in lollipop too (and better than new one since it's usable everywhere, including in remote views) just change your circular_progress_bar.xml
code to this:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="270"
android:toDegrees="270">
<shape
android:innerRadiusRatio="2.5"
android:shape="ring"
android:thickness="1dp"
android:useLevel="true"> <!-- Just add this line -->
<gradient
android:angle="0"
android:endColor="#007DD6"
android:startColor="#007DD6"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>
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);
}
Here is a simple customview for display circle progress. You can modify and optimize more to suitable for your project.
class CircleProgressBar @JvmOverloads constructor(
context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : View(context, attrs, defStyleAttr) {
private val backgroundWidth = 10f
private val progressWidth = 20f
private val backgroundPaint = Paint().apply {
color = Color.LTGRAY
style = Paint.Style.STROKE
strokeWidth = backgroundWidth
isAntiAlias = true
}
private val progressPaint = Paint().apply {
color = Color.RED
style = Paint.Style.STROKE
strokeWidth = progressWidth
isAntiAlias = true
}
var progress: Float = 0f
set(value) {
field = value
invalidate()
}
private val oval = RectF()
private var centerX: Float = 0f
private var centerY: Float = 0f
private var radius: Float = 0f
override fun onSizeChanged(w: Int, h: Int, oldw: Int, oldh: Int) {
centerX = w.toFloat() / 2
centerY = h.toFloat() / 2
radius = w.toFloat() / 2 - progressWidth
oval.set(centerX - radius,
centerY - radius,
centerX + radius,
centerY + radius)
super.onSizeChanged(w, h, oldw, oldh)
}
override fun onDraw(canvas: Canvas?) {
super.onDraw(canvas)
canvas?.drawCircle(centerX, centerY, radius, backgroundPaint)
canvas?.drawArc(oval, 270f, 360f * progress, false, progressPaint)
}
}
Example using
xml
<com.example.androidcircleprogressbar.CircleProgressBar
android:id="@+id/circle_progress"
android:layout_width="200dp"
android:layout_height="200dp" />
kotlin
class MainActivity : AppCompatActivity() {
val TOTAL_TIME = 10 * 1000L
override fun onCreate(savedInstanceState: Bundle?) {
...
timeOutRemoveTimer.start()
}
private var timeOutRemoveTimer = object : CountDownTimer(TOTAL_TIME, 10) {
override fun onFinish() {
circle_progress.progress = 1f
}
override fun onTick(millisUntilFinished: Long) {
circle_progress.progress = (TOTAL_TIME - millisUntilFinished).toFloat() / TOTAL_TIME
}
}
}
Result
I'm new so I can't comment but thought to share the lazy fix. I use Pedram's original approach as well, and just ran into the same Lollipop issue. But alanv over in another post had a one line fix. Its some kind of bug or oversight in API21. Literally just add android:useLevel="true"
to your circle progress xml. Pedram's new approach is still the proper fix, but I just thought I share the lazy fix as well.
