Apps Change Text on Inactive tab with tabLayout, viewPager?

[masterpda13]

I have an application with a Navigation Drawer that has 6 fragments. The first fragment is the MainFragment. MainFragment has 4 fragments. In the MainActivity, an AsyncTask(MyTask) is set up which changes the text in the OneFragment(Common) and in the ThirdFragment(Internal) of MainFragment. My question is: this AsyncTask can not change tex on TextView on this tabs(Common and Internal). How to fix it. What I did: changing text on TextView works if the Common(FragmentOne) tab is activated with method TabLayout.getTabAt(0).select () and the Internal(FragmentThree) tab with tabLayout.getTabAt(2).select(). But this is not acceptable. I do not know of other ways. How to do this without tabLayout.getTabAt(0).select() and tabLayout.getTabAt(2).select() The source code is attached. MainActivity MainFragment FragmentOne(Common) FragmentTwo(Battery) FragmentThree(Internal) FragmentFour(Internal) FragmentFirst FragmentSecond .... FragmentSix

class MyTask extends AsyncTask<Void, Void, Integer> {

    @Override
    protected Integer doInBackground(Void... params) {
        //Thread.currentThread().setPriority(Thread.MIN_PRIORITY);
        while (!isCancelled()) {
            try {
                TimeUnit.SECONDS.sleep(3);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            publishProgress();
        }
        return null;
    }

    @Override
    protected void onProgressUpdate(Void... values) {
        super.onProgressUpdate(values);

        Log.d(TAG, "MainFragment do try");

        try {
            //tabLayout.getTabAt(0).select(); textV1.setText not work when tab(0) inactive

            TextView textV1 = (TextView) findViewById(R.id.TextName2);
            textV1.setText("InternalMemory");

            TextView textV2 = (TextView) findViewById(R.id.textParam6);
            textV2.setText("All: "+bytesToHuman(getTotalInternalSpace()));

            TextView textV3 = (TextView) findViewById(R.id.textParam7);
            textV3.setText("Path: "+getInternalMemoryPath());

            TextView textV4 = (TextView) findViewById(R.id.textParam9);
            textV4.setText("Free: "+bytesToHuman(getAvailableInternalSpaceSize()));

            int t4 = (int) Math.ceil(((getAvailableInternalSpaceSize()*100)/getTotalInternalSpace()));
            TextView textV5 = (TextView) findViewById(R.id.textParam8);
            textV5.setText(String.format("%d ",t4) + "% ");

            ProgressBar textV6 = (ProgressBar) findViewById(R.id.progressBar1);
            textV6.setProgress(t4);
            if (t4<=20) {
                textV6.getProgressDrawable().setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);
            } else if ((t4>20) && (t4<=40)){

                Log.d(TAG, "MainFragment do internalMemoryInfo");


            //tabLayout.getTabAt(2).select();ThreeFragment.showText not work when tab(2) inactive

            ThreeFragment.showText(textV2.getText() + "\n" +
                                   textV3.getText() + "\n" +

            Log.d(TAG, "MainFragment posle internalMemoryInfo");

            } catch (Exception e) {
                Log.d(TAG, "MainFragment in Exception");
                e.printStackTrace();
            }
    }
}

I'm unable to open your zip archive.

Instead of trying to set the value of a TextView on a tab which isn't displayed, I would make the tab fragment get the value itself when tab becomes selected, and set the TextView accordingly.

There is yandex disk link to my file(winrar) https://yadi.sk/d/2IyWYe0f3J6Pmo

Update the archive
And how can I update fragment(tab) periodically. In period 3 seconds.

Get the tab fragment to start a thread which runs continuously, and periodically updates the value.

In total, it was necessary to transfer MyTask extends AsyncTask from MainActivity to MainFragment)))
Thank you all. The question is close.
