Android: Start The Circular Progress Bar From Top (270°)
Answer :
Try specifying rotation degrees to your progress items.
<?xml version="1.0" encoding="UTF-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@android:id/progress"> <rotate android:fromDegrees="270" android:toDegrees="270" android:pivotX="50%" android:pivotY="50%" > <shape android:innerRadiusRatio="2.5" android:shape="ring" android:thicknessRatio="25.0" > <gradient android:centerColor="@color/gray" android:endColor="@color/gray" android:startColor="@color/gray" android:type="sweep" /> </shape> </rotate> </item> <item android:id="@android:id/secondaryProgress"> <rotate android:fromDegrees="270" android:toDegrees="270" android:pivotX="50%" android:pivotY="50%" > <shape android:innerRadiusRatio="2.5" android:shape="ring" android:thicknessRatio="25.0" > <gradient android:centerColor="@color/green" android:endColor="@color/green" android:startColor="@color/green" android:type="sweep" /> </shape> </rotate> </item> </layer-list>
You can also apply a rotation to your ProgressBar in layout XML. In your case -90° would solve your problem.
<ProgressBar android:id="@+id/progressDemo" style="?android:attr/progressBarStyleHorizontal" android:layout_width="152dp" android:layout_height="152dp" android:layout_centerInParent="true" android:indeterminate="false" android:progress="10" android:rotation="-90" android:progressDrawable="@drawable/circular_progress_bar" />
Here's how I made circular progressbar with percentage inside circle in pure code without any library.
Reference is taken from here : circular progress bar android
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:
