Android 列表对话框 setItems

    private Button button;
    private final CharSequence[] items = { "北京","上海","广州" };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        button = (Button) findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {

            @Override
            public  onClick(View v) {
                // TODO Auto-generated method stub

                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                builder.setTitle("请选择以下城市");
                 builder.setMessage("请选择以下城市");  使用setMessage会覆盖setItems内容

                builder.setItems(items, OnClickListener() {

                    @Override
                    void onClick(DialogInterface dialog,int which) {
                         TODO Auto-generated method stub
                        CharSequence sequence = items[which];
                        Toast.makeText(MainActivity.this,"select " + sequence,1).show();
                    }
                });

                AlertDialog dialog = builder.create();
                dialog.show();
            }
        });
    }
