为编程创建的对话框按钮提供默认的对话框按钮样式

Question

我正在以编程方式创建一个Dialog（不是AlertDialog，并且不要告诉我使用一个，因为它会产生另一个无法解决的问题），它有自己的布局层次结构（下面的代码）。由于我使用的是Dialog而不是AlertDialog，因此没有＆＃34; setPositive / NegativeButton＆＃34;方法所以我必须像对待Dialog的其他视图一样创建按钮。问题是，虽然其他视图使用默认对话框样式，但按钮不会。我尽我所能，在互联网和源代码中查看对话框的默认主题和样式，调试程序以找到对话框使用的主题并将其应用于按钮，但没有任何效果。按钮的风格从来都不是正确的。

这里是代码：

    dialog = new Dialog(context);

    RelativeLayout relativeLayout = new RelativeLayout(context);
    relativeLayout.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.MATCH_PARENT));

    ListView listView = new ListView(context);
    listView.setAdapter(adapter);

    relativeLayout.addView(listView);

    LinearLayout buttonsLayout = new LinearLayout(context);
    buttonsLayout.setOrientation(LinearLayout.HORIZONTAL);
    RelativeLayout.LayoutParams buttonsLayoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    buttonsLayoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    buttonsLayout.setLayoutParams(buttonsLayoutParams);

    Button cancelButton = null;

    if(Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
        cancelButton = new Button(new ContextThemeWrapper(context, android.R.style.Theme_Dialog));
    //this seems to use the right style for buttons on android <= 2.3.3

    } else if(Build.VERSION.SDK_INT > Build.VERSION_CODES.GINGERBREAD_MR1 && Build.VERSION.SDK_INT <= Build.VERSION_CODES.HONEYCOMB_MR2) {
        cancelButton = new Button(new ContextThemeWrapper(context, android.R.style.Theme_Holo_Light_Dialog));
    //this is not the right style. see image below

    } else {
        cancelButton = new Button(context);
        cancelButton.setBackgroundColor(android.R.drawable.dialog_holo_light_frame);
    //this sets the background color of the buttons to match the one of the dialog,
    //but this way the buttons have no visible margins and click animation
    }

    cancelButton.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1));
    cancelButton.setText("Cancel");
    cancelButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {

            dialog.dismiss();
        }
    });

    Button sendButton = null;

    if(Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
        sendButton = new Button(new ContextThemeWrapper(context, android.R.style.Theme_Dialog));
    //this seems to use the right style for buttons on android <= 2.3.3

    } else if(Build.VERSION.SDK_INT > Build.VERSION_CODES.GINGERBREAD_MR1 && Build.VERSION.SDK_INT <= Build.VERSION_CODES.HONEYCOMB_MR2) {
        sendButton = new Button(new ContextThemeWrapper(context, android.R.style.Theme_Holo_Light_Dialog));
    //this is not the right style. see image below

    } else {
        sendButton = new Button(context);
        sendButton.setBackgroundColor(android.R.drawable.dialog_holo_light_frame);
    //this sets the background color of the buttons to match the one of the dialog,
    //but this way the buttons have no visible margins and click animation
    }

    sendButton.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1));
    sendButton.setText("Send");
    sendButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {

            //do something

            dialog.dismiss();
        }
    });

    buttonsLayout.addView(cancelButton);
    buttonsLayout.addView(sendButton);

    relativeLayout.addView(buttonsLayout);

    dialog.setCanceledOnTouchOutside(false);
    dialog.setContentView(relativeLayout);
    dialog.setTitle("Insert");
    dialog.show();

这里是android＆gt;中的结果2.3.3＆amp;＆amp; ＆lt; = 3.2：
