有没有办法使用单选项向alertDialog添加摘要或其他文本?我希望有一个粗体标题和一些带有一些额外信息的小文本。

"由于列表出现在对话框的内容区域中,因此对话框无法显示消息和列表": http://developer.android.com/guide/topics/ui/dialogs.html
似乎按钮,消息和多项选择项是独占的。 如果您想同时拥有消息和多项选项,则必须使用自己的DialogFragment自定义内容

设置标题,然后设置消息:
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set title
alertDialogBuilder.setTitle("Your Title");
// set dialog message
alertDialogBuilder
.setMessage("Click yes to exit!")
.setCancelable(false)
.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, close
// current activity
MainActivity.this.finish();
}
})
.setNegativeButton("No",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}

您可以在AlertDialog的构建方法setSingleChoiceItems
中使用 -
final CharSequence[] items = {"Red", "Green", "Blue"};
AlertDialog dialog = new AlertDialog.Builder(this).setMessage("Hello world").show();
TextView textView = (TextView) dialog.findViewById(android.R.id.message);
textView.setTextSize(10); //small text font
dialog.setTitle("Colors");
dialog.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
Toast.makeText(getApplicationContext(),
items[item], Toast.LENGTH_SHORT).show();
}
});

您可以这样做:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Title");
builder.setMessage("Message");
builder.setPositiveButton("OK", null);
AlertDialog dialog = builder.show();
// Must call show() prior to fetching text view
TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);
