How to Customize a Progress Bar In Android

Question

I am working on an app in which I want to show a ProgressBar, but I want to replace the default Android ProgressBar.

So how can I customize

Answer 1

Customizing a ProgressBar requires defining the attribute or properties for the background and progress of your progress bar.

Create an XML file named customprogressbar.xml in your res->drawable folder:

custom_progressbar.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Define the background properties like color etc -->
    <item android:id="@android:id/background">
    <shape>
        <gradient
                android:startColor="#000001"
                android:centerColor="#0b131e"
                android:centerY="1.0"
                android:endColor="#0d1522"
                android:angle="270"
        />
    </shape>
   </item>

  <!-- Define the progress properties like start color, end color etc -->
  <item android:id="@android:id/progress">
    <clip>
        <shape>
            <gradient
                android:startColor="#007A00"
                android:centerColor="#007A00"
                android:centerY="1.0"
                android:endColor="#06101d"
                android:angle="270"
            />
        </shape>
    </clip>
    </item>
</layer-list> 

Now you need to set the progressDrawable property in customprogressbar.xml (drawable)

You can do this in the XML file or in the Activity (at run time).

Do the following in your XML:

<ProgressBar
    android:id="@+id/progressBar1"
    style="?android:attr/progressBarStyleHorizontal"
    android:progressDrawable="@drawable/custom_progressbar"         
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

At run time do the following

// Get the Drawable custom_progressbar                     
    Drawable draw=res.getDrawable(R.drawable.custom_progressbar);
// set the drawable as progress drawable
    progressBar.setProgressDrawable(draw);

Edit: corrected xml layout

Answer 2

If you want to do this in code, here is a sample:

pd = new ProgressDialog(MainActivity.this);
pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pd.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
pd.getWindow().setGravity(Gravity.CENTER_HORIZONTAL|Gravity.CENTER_VERTICAL);
TextView tv = new TextView(this);
tv.setTextColor(Color.WHITE);
tv.setTextSize(20);
tv.setText("Waiting...");
pd.setCustomTitle(tv);
pd.setIndeterminate(true);
pd.show();

Using TextView gives you an option to change color, size, and font of your text. Otherwise you can just call setMessage(), as usual.

Answer 3

There are two types of progress bars called determinate progress bar (fixed duration) and indeterminate progress bar (unknown duration).

Drawables for both of types of progress bar can be customized by defining drawable as xml resource. You can find more information about progress bar styles and customization at http://www.zoftino.com/android-progressbar-and-custom-progressbar-examples.

Customizing fixed or horizontal progress bar :

Below xml is a drawable resource for horizontal progress bar customization.

 <?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background"
        android:gravity="center_vertical|fill_horizontal">
        <shape android:shape="rectangle"
            android:tint="?attr/colorControlNormal">
            <corners android:radius="8dp"/>
            <size android:height="20dp" />
            <solid android:color="#90caf9" />
        </shape>
    </item>
    <item android:id="@android:id/progress"
        android:gravity="center_vertical|fill_horizontal">
        <scale android:scaleWidth="100%">
            <shape android:shape="rectangle"
                android:tint="?attr/colorControlActivated">
                <corners android:radius="8dp"/>
                <size android:height="20dp" />
                <solid android:color="#b9f6ca" />
            </shape>
        </scale>
    </item>
</layer-list>

Customizing indeterminate progress bar

Below xml is a drawable resource for circular progress bar customization.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/progress"
        android:top="16dp"
        android:bottom="16dp">
                <rotate
                    android:fromDegrees="45"
                    android:pivotX="50%"
                    android:pivotY="50%"
                    android:toDegrees="315">
                    <shape android:shape="rectangle">
                        <size
                            android:width="80dp"
                            android:height="80dp" />
                        <stroke
                            android:width="6dp"
                            android:color="#b71c1c" />
                    </shape>
                </rotate>           
    </item>
</layer-list>
