Question

问题是，我有一个AlertDialog，其中我通过这个来扩充我的自定义布局：

AlertDialog.Builder mBuilder = new AlertDialog.Builder(getActivity());
View mView  = getLayoutInflater().inflate(R.layout.exp_add, null);
mBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) { 
                         //some of my data and mView manipulation
                    });


mBuilder.setView(mView);
AlertDialog dialog = mBuilder.create();
dialog.show();

问题是如何自定义.setPositiveButton，因为我有一个具有特定背景颜色的视图，但mBuilder添加了一个默认白色背景颜色和粉红色文本按钮的按钮。

有没有办法自定义此按钮？

AlertDialog.Builder builder = new AlertDialog.Builder(context);
    LayoutInflater inflater = context.getLayoutInflater();

    //setting custom view for our dialog
    View myview = inflater.inflate(R.layout.YOUR_CUSTOM_LAYOUT, null);
    builder.setNeutralButton(android.R.string.cancel, null);
    builder.setView(myview);

    //creating an alert dialog from our builder.
    AlertDialog dialog = builder.create();
    dialog.show();

    //retrieving the button view in order to handle it.
    Button neutral_button = dialog.getButton(DialogInterface.BUTTON_NEUTRAL);

    Button positive_button = dialog.getButton(DialogInterface.BUTTON_POSITIVE);


    if (neutral_button != null) {
        neutral_button.setBackgroundDrawable(context.getResources()
                        .getDrawable(R.drawable.custom_background));

        neutral_button.setTextColor(context.getResources()
                        .getColor(android.R.color.white));
    }
    if (positive_button != null) {
        positive_button.setBackgroundDrawable(context.getResources()
                        .getDrawable(R.drawable.custom_background));

        positive_button.setTextColor(context.getResources()
                        .getColor(android.R.color.white));
    }

如何自定义AlertDialog的默认按钮？
