Common Progress bar in every activity Android

Question

I have modify the solution. I am able to get the progress bar but the progress bar never gets hide

Here is class to create a progress bar with relative layout

public class ProgressBarHandler {
    private ProgressBar mProgressBar;
    private Context mContext;
    private View _baseView;
    private View _hideView;
    public ProgressBarHandler(Context context,View baseView, View hideView) {
        mContext = context;
        _baseView = baseView;
        _hideView = hideView;

        ViewGroup layout = (ViewGroup) _baseView;//((Activity) context).findViewById(android.R.id.content).getRootView();

        mProgressBar = new ProgressBar(context, null, android.R.attr.progressBarStyleLarge);
        mProgressBar.setIndeterminate(true);

        RelativeLayout.LayoutParams params = new
                RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);

        RelativeLayout rl = new RelativeLayout(context);

        rl.setGravity(Gravity.CENTER);
        rl.addView(mProgressBar);

        layout.addView(rl, params);

        hide();
    }

    public void show() {
        mProgressBar.setVisibility(View.VISIBLE);
        _hideView.setVisibility(View.INVISIBLE);
    }

    public void hide() {
        mProgressBar.setVisibility(View.INVISIBLE);
        _hideView.setVisibility(View.VISIBLE);
    }
}

This is my xml file

Here is the activity class which call the progress bar

public class ProfileActivity extends AppCompatActivity {

    FrameLayout profile_root_layout;
    CoordinatorLayout layot_to_hide;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_profile);
        profile_root_layout = (FrameLayout) findViewById(R.id.profile_activity);
        layot_to_hide = (CoordinatorLayout) findViewById(R.id.layout_to_hide);
         new userProfileTask().execute();
    }




    public class userProfileTask extends AsyncTask {
        @Override
        protected void onPreExecute() {
            new ProgressBarHandler(getBaseContext(),profile_root_layout,layot_to_hide).show();
            super.onPreExecute();
        }

        @Override
        protected Boolean doInBackground(Void... params) {
            try {
                Thread.sleep(2000);

            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            return null;
        }

        @Override
        protected void onPostExecute(Boolean aBoolean) {

            new ProgressBarHandler(getBaseContext(),profile_root_layout,layot_to_hide).hide();
        }
    }

}

The progress bar never gets hides.Where I am doing mistake.

You could use a parent Activity. This activity class extends AppCompatActivity . Other Activities will extend this Activity. For example the name of this activity is AbstractActivty.

public class  AbstractActivty extends AppCompatActivity{

      AlertDialog alertDialogProgressBar;

      public void showLoadingProgressBar(String message, boolean cancalable) {
        if (isActivityPaused)
            return;

          AlertDialog.Builder adb = new AlertDialog.Builder(this);
          View view = getLayoutInflater().inflate(R.layout.alert_dialog_progressbar_layout,null);
          TextView tv = (TextView) view.findViewById(R.id.idTextViewMessage);
          tv.setText(message);
          adb.setView(view);
          alertDialogProgressBar = adb.create();
          alertDialogProgressBar.setCancelable(cancalable);
          alertDialogProgressBar.show();
}

 public void closeProgressBar() {
        if (alertDialogProgressBar == null) {
            return;
        }
        alertDialogProgressBar.hide();
    }

}

This class have a method which could be called by any other activity that extends AbstractActivty

class MainActivty extends AbstractActivty{
   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // when require to show progressbar
        showLoadingProgressBar("Loading....",true)

        // when required to hide call
        closeProgressBar();

 }

}

Note in Alert Dialog we have used a custom layout "alert_dialog_progressbar_layout.xml"

Hope this will be of help . Thank you.
