Is anybody see this issue. Can any help me to solve this problem, although this is latest android version.

Code: (I have not used xml code to create dialog, here is java code:)

AlertDialog.Builder alert = new AlertDialog.Builder(this);
        alert.setTitle(R.string.feedback_label);
        alert.setMessage(msgStrId);
        alert.setNegativeButton(R.string.close_label, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub
            }
        });
        alert.setPositiveButton(R.string.rate_app, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub
            }
        });
        alert.setNeutralButton(R.string.feedback_label,new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) 
            {
                // TODO Auto-generated method stub
            }
        });
        alert.setOnCancelListener(new DialogInterface.OnCancelListener() 
        {
            @Override
            public void onCancel(DialogInterface dialog) 
            {
                // TODO Auto-generated method stub
            }
        });
        AlertDialog alertDialog = alert.create();
        alertDialog.show();

Answer 1

I know, I am too late. But I share my suggestion here. Maybe it will be helpful.

  AlertDialog alertDialog  = alert.create();
    alertDialog .show();
    alertDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setAllCaps(false);
    alertDialog.getButton(DialogInterface.BUTTON_POSITIVE).setAllCaps(false);
    alertDialog.getButton(DialogInterface.BUTTON_NEUTRAL).setAllCaps(false);
 alertDialog.show();

Answer 2

AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);

styles.xml

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog">
    <item name="android:textAllCaps">false</item>
</style>
