android - 带确定/取消按钮的 AlertDialog

Question

我创建了这个 AlertDialog:

            String msg = "Connessione lenta o non funzionante";
            AlertDialog alertDialog;
            alertDialog = new AlertDialog.Builder(HomePage.this).create();
            alertDialog.setTitle("Timeout connessione");
            alertDialog.setMessage(msg);
            alertDialog.show();

我想添加确定和取消按钮。我在 StackOverflow 上进行了搜索，但似乎已弃用 setButton 方法。我还为 AlertDialog.Builder 找到了 setPositiveButton 和 setNegativeButton，但即使是它们似乎也已被弃用。

Answer 1

您可以使用 AlertDialog.Builder.setPositiveButton 和 AlertDialog.Builder.setNegativeButton，两者都没有被弃用(see the documentation):

new AlertDialog.Builder(HomePage.this)
        .setTitle("Timeout connessione")
        .setMessage("Connessione lenta o non funzionante")
        .setNegativeButton(android.R.string.cancel, null) // dismisses by default
        .setPositiveButton(android.R.string.ok, new OnClickListener() {
            @Override public void onClick(DialogInterface dialog, int which) {
                // do the acknowledged action, beware, this is run on UI thread
            }
        })
        .create()
        .show();
