how to read content description for an alert dialog in android

Question

I am alerting the user after some action and showing alert dialog but when accessibility is on it is not reading full alert dailog header and body. It is reading only header. I found this issue in samsung galaxy s5. Please help me solving this issue.

public class TransactionDialog extends DialogFragment {

private int _state = -1;
private final String TITLE = "TITLE";
private final String MESSAGE = "MESSAGE";
private final String POS_TEXT = "POS_TEXT";     
private final String STATE = "STATE";
private int _title = 0;
private int _message = 0;
private int _positiveText = 0;  
private NoticeDialogListener mListener;
Logger logger = Logger.getNewLogger("com.ui.TransactionDialog");
boolean actionPerformed = false;    
AlertDialog dialog = null;

public TransactionDialog() {

}

public void setListener(NoticeDialogListener listener) {
    this.mListener = listener;
}

public TransactionDialog(int title, int message, int positiveText, int state) {
    this._title = title;
    this._message = message;
    this._positiveText = positiveText;
    this._state = state;
}

public int getState() {
    return _state;
}

@Override
public void onSaveInstanceState(Bundle outState) {
    // TODO Auto-generated method stub
    super.onSaveInstanceState(outState);
    outState.putInt(TITLE, this._title);
    outState.putInt(MESSAGE, this._message);
    outState.putInt(POS_TEXT, this._positiveText);  
    outState.putInt(STATE, this._state);
}

@Override
public void onResume() {
    super.onResume();
    logger.debug("TITLE:" + this._title);
    logger.debug("_message:" + this._message);
    logger.debug("_positiveText:" + this._positiveText);        
    logger.debug("_state:" + this._state);
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    logger.debug("Created");
}

@Override
public void onDismiss(DialogInterface dialog) {
    // TODO Auto-generated method stub
    super.onDismiss(dialog);
    mListener.onDialogDismissed();
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    logger.debug("ON CREATE");

    if (savedInstanceState != null) {
        this._title = savedInstanceState.getInt(TITLE);
        this._message = savedInstanceState.getInt(MESSAGE);
        this._positiveText = savedInstanceState.getInt(POS_TEXT);   
        this._state = savedInstanceState.getInt(STATE);
    }

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());       
    builder.setTitle(getResources().getString(this._title))
            .setMessage(getResources().getString(_message))             
            .setPositiveButton(getResources().getString(_positiveText), new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {   
                    if(actionPerformed) 
                        return;
                    actionPerformed = true;
                    mListener.onDialogPositiveClick(TransactionDialog.this);                                
                }
            });     



    dialog = builder.create();
    dialog.setCanceledOnTouchOutside(false);        
    dialog.show();

    dialog.setOnKeyListener(new OnKeyListener() {

        @Override
        public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
            // TODO Auto-generated method stub
            if (keyCode == KeyEvent.KEYCODE_BACK) {
                mListener.onDialogPositiveClick(TransactionDialog.this);        
            }
            return false;
        }
    });

    return dialog;
}



@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);

    // Verify that the host activity implements the callback interface
    try {
        // Instantiate the NoticeDialogListener so we can send events to the
        // host
        mListener = (NoticeDialogListener) activity;
    } catch (ClassCastException e) {
        // The activity doesn't implement the interface, throw exception
        throw new ClassCastException(activity.toString()
                + " must implement NoticeDialogListener");
    }

}

public interface NoticeDialogListener {
    public void onDialogPositiveClick(DialogFragment dialog);

    public void onDialogDismissed();
}}

Here i am using the txndialog class for creating the alert dialog.

private TransactionDialog transactionDialog;
    transactionDialog = (TransactionDialog) newTransactionFrgment;
            transactionDialog.setListener(this);
 transactionDialog = new TransactionDialog(R.string.transaction_complete_header, R.string.transaction_complete_message,
                    R.string.transaction_complete_positive_button, STATE_SET_TRANSACION);
            transactionDialog.show(getFragmentManager(), TRANSACTION_DIALOG_TAG);
