Question

我想在Android中的AlertDialog中调整按钮的字体大小（正面，负面和中性）。到目前为止，我只看到了标题的字体大小调整和AlertDialog的消息。

以下是我用来创建对话框的代码：

public void showPopUp(){
    final AlertDialog.Builder dialog = new AlertDialog.Builder(this);
    //dialog.setContentView(R.layout.dialog_main);
    pvuDB.open();
    imageDB.open();


    dialog.setTitle("Select Unit and Quantity of Variant");

    //set drawables ArrayList here
            //here I'm just fetching image paths because my dialog has a listView
            //made up of images in its message
    drawables = imageDB.fetchDialogImages(getIntent().getStringExtra("productName"), 
            pvuDB.getVariantOfProduct(getIntent().getStringExtra("productName"), variantPosition));
    imageDB.close();

        //R.layout.dialog_main is just a plain white layout with a listView
    View view = getLayoutInflater().inflate(R.layout.dialog_main, null);

    //get unit details here
    final ArrayList dialogList = getDialogData();
    pvuDB.close();

    final ListView lv = (ListView) view.findViewById(R.id.custom_list);
    customListAdapterDialog = new CustomListAdapterDialog(OrderForm.this, dialogList);

    lv.setAdapter(customListAdapterDialog);

    //TODO this one is the dialog that sets the quantity
    lv.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> a, View v, final int position, long id){
            //Long listView onclick function here
    });

    dialog.setView(view);
    dialog.show();
}

我知道我可以去使用自定义对话框，但这对我来说太过分了，因为我只是调整按钮的字体大小。

是否可以在不使用自定义对话框的情况下增加/减少AlertDialog中按钮的字体大小？

首先将这些样式添加到styles.xml

  <style name="AlertS" parent="android:Theme.Dialog">
        <item name="android:textSize">10sp</item>
 </style>

之后，在创建警报对话框时编写此代码。

 ContextThemeWrapper con = new ContextThemeWrapper( this, R.style.AlertS );
 AlertDialog.Builder bui = new AlertDialog.Builder( con );
