I have tried to show the dialog box while the user giving the wrong username or password, using the below code.

private void showAlert(String title, String msg) {
    customDialog = new Dialog(LoginActivity.this,
            android.R.style.Theme_Dialog);
    customDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    customDialog.setContentView(R.layout.custom_alert_dialog);

    tvTitle = (TextView) customDialog
            .findViewById(R.id.dialog_title);
    tvMsg = (TextView) customDialog
            .findViewById(R.id.dialog_message);
    btnNeutral = (Button) customDialog
            .findViewById(R.id.closeAlert);

    tvMsg.setText(msg);
    tvTitle.setText(title);

    tvMsg.sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_FOCUSED);
    tvMsg.setFocusable(true);

    btnNeutral.setText("Close");
    btnNeutral.setVisibility(View.VISIBLE);
    btnNeutral.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            customDialog.dismiss();
        }
    });
    customDialog.show();
    tvMsg.requestFocus();
}

The code working fine but my concern is, when i am trying to use the android talkback. It reads only the title of the dialog box. The talkback needs to read the content(message) of the dialog box instead of title. Can anyone help me to do this?
