Android - ProgressBar
Start
  Material Linear ProgressBar

According to Material Documentation (opens new window):

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"/>

enter image description here (opens new window)

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);
  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"
/>
  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();

    }
}

  Creating Custom Progress Dialog

By Creating Custom Progress Dialog class, the dialog can be used to show in UI instance, without recreating the dialog.

First Create a Custom Progress Dialog Class.

CustomProgress.java

public class CustomProgress {

   public static CustomProgress customProgress = null;
   private Dialog mDialog;

   public static CustomProgress getInstance() {
       if (customProgress == null) {
           customProgress = new CustomProgress();
       }
       return customProgress;
   }

   public void showProgress(Context context, String message, boolean cancelable) {
       mDialog = new Dialog(context);
    // no tile for the dialog
       mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
       mDialog.setContentView(R.layout.prograss_bar_dialog);
       mProgressBar = (ProgressBar) mDialog.findViewById(R.id.progress_bar);
    //  mProgressBar.getIndeterminateDrawable().setColorFilter(context.getResources()
    // .getColor(R.color.material_blue_gray_500), PorterDuff.Mode.SRC_IN);
       TextView progressText = (TextView) mDialog.findViewById(R.id.progress_text);
       progressText.setText("" + message);
       progressText.setVisibility(View.VISIBLE);
       mProgressBar.setVisibility(View.VISIBLE);
    // you can change or add this line according to your need
       mProgressBar.setIndeterminate(true);
       mDialog.setCancelable(cancelable);
       mDialog.setCanceledOnTouchOutside(cancelable);
       mDialog.show();
   }

   public void hideProgress() {
       if (mDialog != null) {
           mDialog.dismiss();
           mDialog = null;
       }
   }
}

Now creating the custom progress layout

prograss_bar_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="65dp"
    android:background="@android:color/background_dark"
    android:orientation="vertical">

    <TextView
        android:id="@+id/progress_text"
        android:layout_width="wrap_content"
        android:layout_height="40dp"
        android:layout_above="@+id/progress_bar"
        android:layout_marginLeft="10dp"
        android:layout_marginStart="10dp"
        android:background="@android:color/transparent"
        android:gravity="center_vertical"
        android:text=""
        android:textColor="@android:color/white"
        android:textSize="16sp"
        android:visibility="gone" />

    <-- Where the style can be changed to any kind of ProgressBar -->

    <ProgressBar
        android:id="@+id/progress_bar"
        style="@android:style/Widget.DeviceDefault.ProgressBar.Horizontal"
        android:layout_width="match_parent"
        android:layout_height="30dp"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_gravity="center"
        android:background="@color/cardview_dark_background"
        android:maxHeight="20dp"
        android:minHeight="20dp" />

</RelativeLayout>

This is it. Now for calling the Dialog in Code

CustomProgress customProgress = CustomProgress.getInstance();

// now you have the instance of CustomProgres
// for showing the ProgressBar

customProgress.showProgress(#Context, getString(#StringId), #boolean);

// for hiding the ProgressBar

customProgress.hideProgress();
  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);
  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"

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"
