Android：以编程方式从Java代码填充Spinner

Question

如何以编程方式从java代码填充旋转器？

我在布局中有一个旋转器，如下所示：

 <Spinner
     android:id="@+id/consultation_deseases"
     android:layout_width="@dimen/bigSpinnerWidth"
     android:layout_height="@dimen/bigSpinnerHeight"
     android:prompt="@string/disease_prompt" />

Answer 1

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

此外，为了找出所选择的内容，您可以执行如下操作

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}
