更改AlertDialog.Builder中按钮的颜色

Question

给定一个函数

private void showInputDialog() {
    final AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
    final EditText input = new EditText(getActivity());
    input.setSingleLine();
    FrameLayout container = new FrameLayout(getActivity());
    FrameLayout.LayoutParams params = new  FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    params.leftMargin= convertDpToPx(25);                                       //remember to scale correctly
    params.rightMargin= convertDpToPx(30);
    input.setLayoutParams(params);
    container.addView(input);
    alert.setTitle("Change City");
    alert.setMessage("Hey there, could not find the city you wanted. Please enter a new one:\n");
    alert.setView(container);
    alert.setPositiveButton("Go", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            changeCity(input.getText().toString());
        }
    });
    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });
    alert.show();
}

现在,当我在我的应用程序中获得此AlertDialog.Builder时,按钮颜色为绿色(默认来自Android 5),但EditText颜色为Pink(R.color.coloraccent).如何将按钮的颜色更改为粉红色？

任何帮助,将不胜感激

试试这样

alertDialog.show(); 

只有在.show()被调用之后. 试试这个片段

//for negative side button
    alertDialog.getButton(dialog.BUTTON_NEGATIVE).setTextColor(neededColor); 
//for positive side button
    alertDialog.getButton(dialog.BUTTON_POSITIVE).setTextColor(neededColor);
