How to add progress bar over dialog

Question

Whenever I want to show progress bar into my app, I call this method and this method adds ProgressBar into my layout.

Problem : I want to show this progress bar over Dialog, but Dialog is always shown above. What can be done for this situation?

public static void showProgressBar(@NonNull final Activity activity) {
    try {
        if (activity == null) {
            LogManager.printStackTrace(new NullActivityException());
            return;
        }
        View view = activity.findViewById(android.R.id.content);
        if (view == null) {
            LogManager.printStackTrace(new NullPointerException("content view is null"));
            return;
        }
        View rootView = activity.findViewById(android.R.id.content).getRootView();
        if (rootView == null || !(rootView instanceof ViewGroup)) {
            LogManager.printStackTrace(new NullPointerException("rootView is null or not an instance of ViewGroup"));
            return;
        }
        final ViewGroup layout = (ViewGroup) rootView;

        final ProgressBar progressBar = new ProgressBar(activity);
        progressBar.setIndeterminate(true);
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            Drawable wrapDrawable = DrawableCompat.wrap(progressBar.getIndeterminateDrawable());
            DrawableCompat.setTint(wrapDrawable, ContextCompat.getColor(activity, R.color.colorAccent));
            progressBar.setIndeterminateDrawable(DrawableCompat.unwrap(wrapDrawable));
        }
        RelativeLayout.LayoutParams params = new
                RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,
                RelativeLayout.LayoutParams.MATCH_PARENT);
        final RelativeLayout rl = new RelativeLayout(activity);
        rl.setBackgroundColor(ActivityCompat.getColor(activity, R.color.tc_hint_grey_alpha));
        rl.setClickable(true);
        rl.setTag("#$UniqueProgressBar");
        ViewGroup.LayoutParams params2 = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                120);
        rl.setGravity(Gravity.CENTER);
        rl.addView(progressBar, params2);
        LogManager.i("ProgressBar", "ProgressUtils.showProgressBar->called");
        layout.addView(rl, params);

        mRunnable = new Runnable() {
            @Override
            public void run() {
                LogManager.i("ProgressBar", "ProgressUtils.showProgressBar->120 secs timeout");
                hideProgressBar(activity);
            }
        };
        mHandler = new Handler();
        mHandler.postDelayed(mRunnable, 120000);

        LogManager.i("ProgressBar", "Added");
    } catch (Exception e) {
        LogManager.printStackTrace(e);
    }

}

Try something like this, it should work globally :

public static void showProgressBar(@NonNull final Activity activity) {
    try {
        if (activity == null) {
            LogManager.printStackTrace(new NullActivityException());
            return;
        }

        final WindowManager wm = (WindowManager) activity.getApplicationContext().getSystemService(Activity.WINDOW_SERVICE);

        final ProgressBar progressBar = new ProgressBar(activity);
        progressBar.setIndeterminate(true);
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
            Drawable wrapDrawable = DrawableCompat.wrap(progressBar.getIndeterminateDrawable());
            DrawableCompat.setTint(wrapDrawable, ContextCompat.getColor(activity, R.color.colorAccent));
            progressBar.setIndeterminateDrawable(DrawableCompat.unwrap(wrapDrawable));
        }

        WindowManager.LayoutParams windowLayoutParams = new WindowManager.LayoutParams();
                windowLayoutParams.gravity = Gravity.CENTER;
                windowLayoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_PANEL;
                windowLayoutParams.token = activity.getWindow().getDecorView().getWindowToken();
                windowLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;

        windowLayoutParams.height = LayoutParams.MATCH_PARENT;
        windowLayoutParams.width = LayoutParams.MATCH_PARENT;

        wm.addView(progressBar, windowLayoutParams);

        LogManager.i("ProgressBar", "ProgressUtils.showProgressBar->called");
        layout.addView(rl, params);

        mRunnable = new Runnable() {
            @Override
            public void run() {
                LogManager.i("ProgressBar", "ProgressUtils.showProgressBar->120 secs timeout");
                hideProgressBar(activity);
            }
        };
        mHandler = new Handler();
        mHandler.postDelayed(mRunnable, 120000);

        LogManager.i("ProgressBar", "Added");
    } catch (Exception e) {
        LogManager.printStackTrace(e);
    }

}

Android has a ProgressDialog with AlertDialog as base class, and adds a progress functionality:

  ProgressDialog progress = new ProgressDialog(this);
  progress.setMessage("Downloading Music");
  progress.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
  progress.setIndeterminate(true);
  progress.setProgress(0);
  progress.show();

and increment:

  progress.setProgress( ... );

Try to use dialog fragment for your dialog and inflate progress bar inside the layout of dialog fragment.For more info check this link.

https://developer.android.com/reference/android/app/DialogFragment.html

Solution 4

Try this

ProgressDialog dialog = ProgressDialog.show(MyActivity.this, "", 
                        "Loading. Please wait...", true);

This will give you a progress bar which can be used as per your requirement.

Solution 5

If you are using custom design layout for your dialog then, you can put your progress bar inside your progress dialogs custom layout and use it from there. Then it will get displayed above ur dialog when ur dialog gets displayed.

Please comment, why vote down?

[Jitesh Mohite]

why you need to add over it ? You can show one and dismiss other. vise versa

[Sarthak Mittal]

@jiteshmohite i think it is a valid requirement.

[Harish Gyanani]

This is not progress bar, it is progress dialog.

Note that this uses a ProgressDialog, which was just deprecated in API 26.

ProgressDialog has now been deprecated since API 26
