Question

知道怎么做吗？这是我的代码片段，困境是我想为我的AlertDialog.builder的标题，消息和按钮文本定制字体。问题是当对话框出现时，没有图标，应该在标题下面的蓝色默认分界线在对话框上方，我的自定义标题正好在消息上方。布局应该是：

(ICON) (TITLE)
(divider)
(Message)
(button1)(button2)

but instead it looks like this:

(divider)

(Title)
(Message)
(button1) (button2)

There is no icon and the divider is above the window...

Here is my code:

final AlertDialog.Builder endGameDialog = new AlertDialog.Builder(myContext);
    // Setting Dialog
    endGameDialog.setCancelable(false);
    endGameDialog.setMessage("Do you want to play again?");


....

if (myScore == roundChoice) {
        AlertDialog alert = endGameDialog.create();
        alert.requestWindowFeature(Window.FEATURE_LEFT_ICON);
        TextView titleV = new TextView(myContext);
        titleV.setTypeface(font);
        titleV.setTextSize(60);
        titleV.setTextColor(Color.WHITE);
        titleV.setShadowLayer(1, 6, -1, redShadow);
        titleV.setText("You won!");
        alert.setCustomTitle(titleV);
        alert.show();
        alert.setFeatureDrawableResource(Window.FEATURE_LEFT_ICON,R.drawable.ic_launcher);
        alert.getWindow().getAttributes();
        dialog = true;
        Button btn1 = alert.getButton(DialogInterface.BUTTON_POSITIVE);
        Button btn2 = alert.getButton(DialogInterface.BUTTON_NEGATIVE);
        TextView messageView = (TextView) alert.findViewById(android.R.id.message);
        messageView.setTypeface(font);
        messageView.setTextSize(54);
        messageView.setTextColor(Color.WHITE);
        messageView.setShadowLayer(1, 6, -1, redShadow);
        btn1.setTypeface(font);
        btn1.setTextSize(44);
        btn1.setTextColor(Color.WHITE);
        btn1.setShadowLayer(1, 6, -1, redShadow);
        btn2.setTypeface(font);
        btn2.setTextSize(44);
        btn2.setTextColor(Color.WHITE);
        btn2.setShadowLayer(1, 6, -1, redShadow);

    }

我最好的建议是制作自定义布局并将其分配给自定义对话框请参阅此参考资料：developer.android.com/guide/topics/ui/dialogs.html

在不使用自定义布局的情况下构建AlertDialog：

// 1. Instantiate an AlertDialog.Builder with its constructor
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

// 2. Chain together various setter methods to set the dialog characteristics
builder.setMessage(R.string.dialog_message)
       .setTitle(R.string.dialog_title)
       .setIcon(R.drawable.dialog_icon); // Here you set your icon

// 3. Get the AlertDialog from create()
AlertDialog dialog = builder.create();

但是我不知道你怎么能为标题分配不同的字体。
