we will learn how to create a circular progress bar in Android Studio that displays the current progress value and has a gray background color. I will also show you how you can customize this progress bar further and add things like a color gradient effect.
After successful Empty activity creation add these lines of code in the files:-
Add a circle.xml file in Drawable folder and add these lines of codes:-
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:shape="ring"
android:thicknessRatio="16"
android:useLevel="false">
<solid android:color="#DDD" />
</shape>
</item>
<item>
<rotate
android:fromDegrees="270"
android:toDegrees="270">
<shape
android:shape="ring"
android:thicknessRatio="16"
android:useLevel="true">
<gradient
android:endColor="@color/colorPrimary"
android:startColor="@color/colorAccent"
android:type="sweep" />
</shape>
</rotate>
</item>
</layer-list>
After that in res folder -> activity_main.xml file add these lines of codes:-
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<ProgressBar
android:id="@+id/progress_bar"
style="@style/CircularDeterminateProgressBar"
android:layout_width="200dp"
android:layout_height="200dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:progress="60" />
<TextView
android:id="@+id/text_view_progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="@style/TextAppearance.AppCompat.Large"
app:layout_constraintBottom_toBottomOf="@+id/progress_bar"
app:layout_constraintEnd_toEndOf="@+id/progress_bar"
app:layout_constraintStart_toStartOf="@+id/progress_bar"
app:layout_constraintTop_toTopOf="@+id/progress_bar"
tools:text="60%" />
<Button
android:id="@+id/button_decr"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="- 10%"
app:layout_constraintStart_toStartOf="@+id/progress_bar"
app:layout_constraintTop_toBottomOf="@+id/progress_bar" />
<Button
android:id="@+id/button_incr"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="+ 10%"
app:layout_constraintEnd_toEndOf="@+id/progress_bar"
app:layout_constraintTop_toBottomOf="@+id/progress_bar" />
</androidx.constraintlayout.widget.ConstraintLayout>
In MainActivity.class file add these lines of codes:-
public class MainActivity extends AppCompatActivity {
Button button_incr, button_decr;
private int progess = 0;
ProgressBar progress_bar;
TextView text_view_progress;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button_decr = findViewById(R.id.button_decr);
button_incr = findViewById(R.id.button_incr);
progress_bar = findViewById(R.id.progress_bar);
text_view_progress = findViewById(R.id.text_view_progress);
updateProgressBar();
button_incr.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (progess <= 90) {
progess += 10;
updateProgressBar();
}
}
});
button_decr.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (progess >= 10) {
progess -= 10;
updateProgressBar();
}
}
});
}
private void updateProgressBar() {
progress_bar.setProgress(progess);
text_view_progress.setText(String.valueOf(progess));
}
}
Now Run this application and see output.
