    final Dialog dialog = new Dialog(SplashActivity.this);
    dialog.requestWindowFeature(Window.FEATURE_LEFT_ICON);
    dialog.setContentView(R.layout.exit_dialog);

    LayoutInflater inflater =(LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View main = inflater.inflate(R.layout.exit_dialog, null);
    dialog.setContentView(main);
    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();

    LinearLayout linear = (LinearLayout)main.findViewById(R.id.layoutAdd);

    NativeExpressAdView mNativeExpressAdView = new NativeExpressAdView(this);
    mNativeExpressAdView.setAdSize(new AdSize(AdSize.FULL_WIDTH, AdSize.AUTO_HEIGHT));
    mNativeExpressAdView.setAdUnitId("ca-app-pub-8410399846074282/9976822052");
    AdRequest.Builder adRequestBuilder = new AdRequest.Builder();

    linear.addView(mNativeExpressAdView);
    mNativeExpressAdView.loadAd(adRequestBuilder.build());

    dialog.setTitle("Title...");

    // set the custom dialog components - text, image and button
    TextView text = (TextView) dialog.findViewById(R.id.dialog_text);
    text.setText("Are you sure you wants to exit ?? " + R.string.app_name);


    Button dialogButton = (Button) dialog.findViewById(R.id.btnCancel);
    // if button is clicked, close the custom dialog
    dialogButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.dismiss();
        }
    });

    Button btnRateus = (Button) dialog.findViewById(R.id.btnRateus);
    // if button is clicked, close the custom dialog
    btnRateus.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Uri uri = Uri.parse("market://details?id=" + getApplicationContext().getPackageName());
            Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);
            // To count with Play market backstack, After pressing back button,
            // to taken back to our application, we need to add following flags to intent.
            goToMarket.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY |
                    Intent.FLAG_ACTIVITY_NEW_DOCUMENT |
                    Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
            try {
                startActivity(goToMarket);
            } catch (ActivityNotFoundException e) {
                startActivity(new Intent(Intent.ACTION_VIEW,
                        Uri.parse("http://play.google.com/store/apps/details?id=" + getApplicationContext().getPackageName())));
            }
        }
    });

    Button btnConfirm = (Button) dialog.findViewById(R.id.btnConfirm);
    // if button is clicked, close the custom dialog
    btnConfirm.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            finish();
        }
    });
    dialog.show();
}

Its not working directly so i was try to inflate NativeExpressAdview in Linearlayout but it not displayed in linearlayout too. Please help me on that ... Thank you in Advance !!

Answer 1

This is due to the AUTO_HEIGHT attribute as mentionned in the official native ad express documentation here :

At this time, the AUTO_HEIGHT constant and FLUID ad size should not be used with Native Ads Express.

Answer 2

Replace this code with this

        // Load an ad into the AdMob banner view.
        NativeExpressAdView adView = (NativeExpressAdView) main.findViewById(R.id.adView);

        AdRequest request = new AdRequest.Builder().build();
        adView.loadAd(request);

On your Code

    NativeExpressAdView mNativeExpressAdView = new NativeExpressAdView(this);
    mNativeExpressAdView.setAdSize(new AdSize(AdSize.FULL_WIDTH, AdSize.AUTO_HEIGHT));
    mNativeExpressAdView.setAdUnitId("ca-app-pub-8410399846074282/9976822052");
    AdRequest.Builder adRequestBuilder = new AdRequest.Builder();

    linear.addView(mNativeExpressAdView);
    mNativeExpressAdView.loadAd(adRequestBuilder.build());
