Answer 1

Use This Within button on Click option or your needs:

final ProgressDialog progressDialog;
progressDialog = new ProgressDialog(getApplicationContext());
progressDialog.setMessage("Loading..."); // Setting Message
progressDialog.setTitle("ProgressDialog"); // Setting Title
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); // Progress Dialog Style Spinner
progressDialog.show(); // Display Progress Dialog
progressDialog.setCancelable(false);
new Thread(new Runnable() {
    public void run() {
        try {
            Thread.sleep(5000);
        } catch (Exception e) {
            e.printStackTrace();
        }
        progressDialog.dismiss();
    }
}).start();

I suggest you when working with listview or recyclerview to use SwipeRefreshLayout. Like this

    <android.support.v4.widget.SwipeRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/swiperefresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/card_recycler_view"
            android:scrollbars="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

</android.support.v4.widget.SwipeRefreshLayout>

Only wrap your view and this will create an animation of refresh when loading data or by swipping down the screen as we can do in many apps.
Here's the documentation of how to use it:

Happy coding !

Please use the sample at tutorialspoint.com. The whole implementation only needs a few lines of code without changing your xml file. Hope this helps.

STEP 1: Import library

import android.app.ProgressDialog;

STEP 2: Declare ProgressDialog global variable

ProgressDialog loading = null;

STEP 3: Start new ProgressDialog and use the following properties (please be informed that this sample only covers the basic circle loading bar without the real time progress status).

loading = new ProgressDialog(v.getContext());
loading.setCancelable(true);
loading.setMessage(Constant.Message.AuthenticatingUser);
loading.setProgressStyle(ProgressDialog.STYLE_SPINNER);

STEP 4: If you are using AsyncTasks, you can start showing the dialog in onPreExecute method. Otherwise, just place the code in the beginning of your button onClick event.

loading.show();

STEP 5: If you are using AsyncTasks, you can close the progress dialog by placing the code in onPostExecute method. Otherwise, just place the code before closing your button onClick event.

loading.dismiss();

Tested it with my Nexus 5 android v4.0.3. Good luck!

You can add the ProgressBar to listview footer:

private ListView listview;
private ProgressBar progressBar;

...

progressBar = (ProgressBar) LayoutInflater.from(this).inflate(R.layout.progress_bar, null);

listview.addFooterView(progressBar);

layout/progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<ProgressBar xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/load_progress"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:indeterminate="true"
     />

when the data is loaded to the adapter view call:

        listview.removeFooterView(progressBar);

Answer 5

I am using this:

loading = ProgressDialog.show(example.this,"",null, true, true);

Process Bar:

Dependency:

     implementation 'com.github.castorflex.smoothprogressbar:library:1.0.0'

XML:

     <fr.castorflex.android.smoothprogressbar.SmoothProgressBar
        xmlns:android="http://schemas.android.com/apk/res/android"                
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/myProcessbar"
        android:layout_width="match_parent"
        android:layout_height="10dp"
        android:indeterminate="true" />

In Res->color

      <color name="pocket_color_1">#ff1635</color>
      <integer-array name="pocket_background_colors">
          <item>@color/pocket_color_1</item>
      </integer-array>

      <color name="pocket_color_stop">#00ff00</color>
      <integer-array name="pocket_background_stop">
          <item>@color/pocket_color_stop</item>
      </integer-array>

In Main:

      public class MainActivity extends AppCompatActivity{
        SmoothProgressBar smoothProgressBar;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          smoothProgressBar=findViewById(R.id.myProcessbar);
          showProcessBar();
          stopAnimation();    // call when required to stop process
        }

        public void showProcessBar(){
          smoothProgressBar.setVisibility(View.VISIBLE);
          smoothProgressBar.setIndeterminateDrawable(new SmoothProgressDrawable.Builder(getApplicationContext())
            .interpolator(new AccelerateInterpolator())
            .progressiveStart(true)
            .progressiveStopSpeed(1000)
            .build());
          smoothProgressBar.setSmoothProgressDrawableBackgroundDrawable(
          SmoothProgressBarUtils.generateDrawableWithColors(
                    getResources().getIntArray(R.array.pocket_background_colors),
                    ((SmoothProgressDrawable)  smoothProgressBar.getIndeterminateDrawable()).getStrokeWidth()));
        }

        public void stopAnimation(){
          smoothProgressBar.setSmoothProgressDrawableBackgroundDrawable(
          SmoothProgressBarUtils.generateDrawableWithColors(
                    getResources().getIntArray(R.array.pocket_background_stop),
                    ((SmoothProgressDrawable)  smoothProgressBar.getIndeterminateDrawable()).getStrokeWidth()));
          smoothProgressBar.progressiveStop();
          Handler handler=new Handler();
          handler.postDelayed(new Runnable() {
            @Override
            public void run() {
               smoothProgressBar.animate().alpha(0.0f).setDuration(6000).translationY(1000);
               smoothProgressBar.setVisibility(View.GONE);
            }
          },1000);
}

      }
