我得到以下代码,在Android中生成一个Alert对话框:
new AlertDialog.Builder(actContainer).
setIcon(R.mipmap.ic_attach_file_black_24dp).
setTitle(strTitle).
setMessage(Html.fromHtml(strHtml)).
setCancelable(false).
setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Log.i("OptimGeek", "prrrrrrr . . .")
}
}
).
show()
这是在groovy,实际上它工作得很好,如何改善“setPossitiveButton”以避免内部类?

使用SAM类型强制或Implicit Closure Coercion:
new AlertDialog.Builder(actContainer).
setIcon(R.mipmap.ic_attach_file_black_24dp).
setTitle(strTitle).
setMessage(Html.fromHtml(strHtml)).
setCancelable(false).
setPositiveButton("OK", { DialogInterface dialogInterface, int i ->
Log.i("OptimGeek", "prrrrrrr . . .")
} as DialogInterface.OnClickListener).
show()
