        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);

        LinearLayout layout = new LinearLayout(this);
        LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        layout.setOrientation(LinearLayout.VERTICAL);
        layout.setLayoutParams(parms);

        layout.setGravity(Gravity.CLIP_VERTICAL);
        layout.setPadding(2, 2, 2, 2);

        TextView tv = new TextView(this);
        tv.setText("Text View title");
        tv.setPadding(40, 40, 40, 40);
        tv.setGravity(Gravity.CENTER);
        tv.setTextSize(20);

        EditText et = new EditText(this);
        etStr = et.getText().toString();
        TextView tv1 = new TextView(this);
        tv1.setText("Input Student ID");

        LinearLayout.LayoutParams tv1Params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        tv1Params.bottomMargin = 5;
        layout.addView(tv1,tv1Params);
        layout.addView(et, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

        alertDialogBuilder.setView(layout);
        alertDialogBuilder.setTitle(title);
        // alertDialogBuilder.setMessage("Input Student ID");
        alertDialogBuilder.setCustomTitle(tv);

        if (isError)
            alertDialogBuilder.setIcon(R.drawable.icon_warning);
        // alertDialogBuilder.setMessage(message);
        alertDialogBuilder.setCancelable(false);

        // Setting Negative "Cancel" Button
        alertDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                dialog.cancel();
            }
        });

        // Setting Positive "OK" Button
        alertDialogBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                if (isError)
                    finish();
                else {
                      Intent intent = new Intent(ChangeDeviceActivity.this,
                      MyPageActivity.class); startActivity(intent);
                }
            }
        });

        AlertDialog alertDialog = alertDialogBuilder.create();

        try {
            alertDialog.show();
        } catch (Exception e) {
            // WindowManager$BadTokenException will be caught and the app would
            // not display the 'Force Close' message
            e.printStackTrace();
        }
