Displaying a TextView depending on whether Android permission is disabled?

Question

I'm trying to display a TextView which appears visible only when a particular Android permission , ie WRITE_EXTERNAL_STORAGE , is not enabled. The idea is to explain to the user why they need to enable it in case they've disabled it the first time, and then have them click the TextView to launch the permission request again. The following is not working for me. How can I accomplish this? I have this in my onCreate() method:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && (checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
} else {
    if (NetworkHelper.isOnline(this)) {
        new AppendParseData().execute();
    }
}

TextView checkFilePermission = (TextView) findViewById(R.id.checkFilePermission);

if (!checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
    checkFilePermission.setVisibility(View.VISIBLE);
}

try this way when you request for permission(I have used READ_CONTACTS permission you can use WRITE_EXTERNAL_STORAGE instead)

if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE)
                    != PackageManager.PERMISSION_GRANTED) {
                requestContactsPermissions1();
            } else {
                setTextVisablity(false);
                checkSimCard();
            }

in onRequestPermissionsResult

public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case REQUEST_CODE_ASK_PERMISSIONS:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // Permission Granted
                    readContacts();
                    setTextVisablity(false);
                } else {
                    // Permission Denied
                    setTextVisablity(true);
                    Toast.makeText(MainActivity.this, "READ_CONTACTS Denied", Toast.LENGTH_SHORT)
                            .show();
                }
                break;
            default:
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }

in the end setTextVisablity method

public void setTextVisablity(boolean isShow) {
        if (isShow) {
            tv.setVisibility(View.VISIBLE);
        } else {
            tv.setVisibility(View.GONE);
        }
    }

Use this code:-


int hasWriteContactsPermission = ContextCompat.checkSelfPermission(this,Manifest.permission.WRITE_EXTERNAL_STORAGE);

if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this,new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE},1);
            return;
    }
    else{
        //Permission already granted show textview here
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case 1:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // Permission Granted                   
                     Toast.makeText(MainActivity.this, " PERMISSION_GRANTED", Toast.LENGTH_SHORT)
                     .show();
                } else {
                    // Permission Denied
                    Toast.makeText(MainActivity.this, " Denied", Toast.LENGTH_SHORT)
                            .show();
                }
                break;
            default:
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }
