Indeterminate ProgressBar

An indeterminate ProgressBar shows a cyclic animation without an indication of progress.

Basic indeterminate ProgressBar (spinning wheel)

<ProgressBar
    android:id="@+id/progressBar"
    android:indeterminate="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

Horizontal indeterminate ProgressBar (flat bar)

<ProgressBar
    android:id="@+id/progressBar"
    android:indeterminate="true"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    style="@android:style/Widget.ProgressBar.Horizontal"/>

Other built-in ProgressBar styles

style="@android:style/Widget.ProgressBar.Small"
style="@android:style/Widget.ProgressBar.Large"
style="@android:style/Widget.ProgressBar.Inverse"
style="@android:style/Widget.ProgressBar.Small.Inverse"
style="@android:style/Widget.ProgressBar.Large.Inverse"

To use the indeterminate ProgressBar in an Activity

ProgressBar progressBar = (ProgressBar) findViewById(R.id.progressBar);
progressBar.setVisibility(View.VISIBLE);
progressBar.setVisibility(View.GONE);

Determinate ProgressBar

A determinate ProgressBar shows the current progress towards a specific maximum value.

Horizontal determinate ProgressBar

<ProgressBar
    android:id="@+id/progressBar"
    android:indeterminate="false"
    android:layout_width="match_parent"
    android:layout_height="10dp"
    style="@android:style/Widget.ProgressBar.Horizontal"/>

Vertical determinate ProgressBar

<ProgressBar
    android:id="@+id/progressBar"
    android:indeterminate="false"
    android:layout_width="10dp"
    android:layout_height="match_parent"
    android:progressDrawable="@drawable/progress_vertical"
    style="@android:style/Widget.ProgressBar.Horizontal"/>

Ring determinate ProgressBar

<ProgressBar
    android:id="@+id/progressBar"
    android:indeterminate="false"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:progressDrawable="@drawable/progress_ring"
    style="@android:style/Widget.ProgressBar.Horizontal"/>

res/drawable/progress_ring.xml

            android:useLevel="true"
            android:thicknessRatio="24"
            android:innerRadiusRatio="2.2">
            <corners android:radius="3dp"/>
            <solid android:color="#0000FF"/>
        </shape>
    </item>

    <item android:id="@android:id/progress">
        <shape
            android:shape="ring"
            android:useLevel="true"
            android:thicknessRatio="24"
            android:innerRadiusRatio="2.2">

            <solid android:color="#FFFFFF"/>
        </shape>
    </item>
</layer-list>

To use the determinate ProgressBar in an Activity.

ProgressBar progressBar = (ProgressBar) findViewById(R.id.progressBar);
progressBar.setSecondaryProgress(100);
progressBar.setProgress(10);
progressBar.setMax(100);

Customized progressbar

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();

    }
}

Tinting ProgressBar

Using an AppCompat theme, the ProgressBar’s color will be the colorAccent you have defined.

To change the ProgressBar color without changing the accent color you can use theandroid:theme attribute overriding the accent color:

<ProgressBar  
    android:theme="@style/MyProgress"
    style="@style/Widget.AppCompat.ProgressBar" />

<!-- res/values/styles.xml -->
<style name="MyProgress" parent="Theme.AppCompat.Light">  
    <item name="colorAccent">@color/myColor</item>
</style>

To tint the ProgressBar you can use in the xml file the attributes android:indeterminateTintMode and android:indeterminateTint

<ProgressBar
    android:indeterminateTintMode="src_in"
    android:indeterminateTint="@color/my_color"
/>

Material Linear ProgressBar

According to Material Documentation:

A linear progress indicator should always fill from 0% to 100% and never decrease in value.

It should be represented by bars on the edge of a header or sheet that appear and disappear.

To use a material Linear ProgressBar just use in your xml:

<ProgressBar
    android:id="@+id/my_progressBar"  
    style="@style/Widget.AppCompat.ProgressBar.Horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

Indeterminate

To create indeterminate ProgressBar set the android:indeterminate attribute to true.

<ProgressBar
    android:id="@+id/my_progressBar"  
    style="@style/Widget.AppCompat.ProgressBar.Horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:indeterminate="true"/>

Determinate

To create determinate ProgressBar set the android:indeterminate attribute to false and use the android:max and the android:progress attributes:

<ProgressBar  
    android:id="@+id/my_progressBar"
    style="@style/Widget.AppCompat.ProgressBar.Horizontal"
    android:indeterminate="false"
    android:max="100"
    android:progress="10"/>

Just use this code to update the value:

ProgressBar progressBar = (ProgressBar) findViewById(R.id.my_progressBar);  
progressBar.setProgress(20);

Buffer

To create a buffer effect with the ProgressBar set the android:indeterminate attribute to false and use the android:max, the android:progress and the android:secondaryProgress attributes:

<ProgressBar  
    android:id="@+id/my_progressBar"
    style="@style/Widget.AppCompat.ProgressBar.Horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:indeterminate="false"
    android:max="100"
    android:progress="10"
    android:secondaryProgress="25"/>

The buffer value is defined by android:secondaryProgress attribute.
Just use this code to update the values:

ProgressBar progressBar = (ProgressBar) findViewById(R.id.my_progressBar);
progressBar.setProgress(20);
progressBar.setSecondaryProgress(50);

Indeterminate and Determinate

To obtain this kind of ProgressBar just use an indeterminate ProgressBar using the android:indeterminate attribute to true.

<ProgressBar  
    android:id="@+id/progressBar"
    style="@style/Widget.AppCompat.ProgressBar.Horizontal"
    android:indeterminate="true"/>

Then when you need to switch from indeterminate to determinate progress use setIndeterminate() method .

ProgressBar progressBar = (ProgressBar) findViewById(R.id.my_progressBar);  
progressBar.setIndeterminate(false);
