    问题是,我有一个 AlertDialog ,其中我通过以下方式对自定义布局进行充气:

    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();
    

    问题是如何定制 .setPositiveButton ,因为我有一个具有特定背景颜色的视图,但mBuilder添加了一个具有默认白色背景颜色的按钮和一个粉红色文本按钮。

    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));
        }
