Android自定义DialogFragment自定义正/负按钮设计

Question

我有一个自定义DialogFragment(支持库).我将布局设置为@ color/GhostWhite,问题是,我找不到一种方法来设置相同颜色的正/负按钮.

这就是我设置按钮的方式:

        builder.setView(view)
    // Add action buttons
           .setPositiveButton("Shout!", new DialogInterface.OnClickListener() {
               @Override
               public void onClick(DialogInterface dialog, int id) {
                   //publishStory(/*shoutText.getText().toString()"woww");
                   mListener.onDialogPositiveClick(WagDialogFragment.this);
               }
           })
           .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
               }
           });  

    return builder.create();

您可以getButton使用DialogInterface.BUTTON_POSITIVE和DialogInterface.BUTTON_NEGATIVE参数来更改两个按钮的颜色:

Button okButton = alertDialog.getButton(DialogInterface.BUTTON_POSITIVE);
// set OK button color here
okButton.setBackgroundColor(R.color.GhostWhite);

Button noButton = alertDialog.getButton(DialogInterface.BUTTON_NEGATIVE);
// set NO button color here
noButton.setBackgroundColor(R.color.GhostWhite);
