protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  // 定义数组
  String[] str = new String[] { "Cocoa", "China", "Cleaner", "Cience" };
  // 绑定控件
  Spinner spinner = (Spinner) findViewById(R.id.sp1);
  AutoCompleteTextView autoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.atv);
  // 定义数组适配器
  // 1：context，2：样式 3：数组
  ArrayAdapter<String> adapter = new ArrayAdapter<>(this,
    android.R.layout.simple_dropdown_item_1line, str);
  // 为控件设定适配器
  spinner.setAdapter(adapter);
