使用列表打开AlertDialog时出错

Question

我需要一些帮助才能从我的应用程序中运行AlertDialog。当有一些错误时，它不会编译。特别是在alertDialog.setItems(items, new DialogInterface.OnClickListener()和setItems()这一行。

请看一下。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_nastavenie_casu);
    // Show the Up button in the action bar.
    getActionBar().setDisplayHomeAsUpEnabled(true);

    final CharSequence[] items = {"30 minút", "45 minút", "60 minút", "75 minút", "90 minút"};

    Button tlacidlo = (Button) findViewById(R.id.spusti);
    EditText pripomienka = (EditText) findViewById(R.id.upozornit_za);

    pripomienka.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {
            // Intent myIntent = new Intent(view.getContext(), agones.class);
            // startActivityForResult(myIntent, 0);

            AlertDialog alertDialog = new AlertDialog.Builder(NastavenieCasu.this).create(); //Read Update
            alertDialog.setTitle("hi");
            alertDialog.setItems(items, new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog, int which) {
                    // do something
                }

                alertDialog.show();  
            });
        }
    }
}

setItems()是AlertDialog.Builder类的一部分，而不是AlertDialog。尝试：

AlertDialog.Builder builder = new AlertDialog.Builder(NastavenieCasu.this); 
builder.setTitle("hi");
builder.setItems(items, new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        // 
        // do something
    }

AlertDialog alertDialog = builder.create();
alertDialog.show();
