如何添加自定义 Spinner？

Question

我正在从事一个必须实现微调器的项目。我的微调器代码如下：

  ArrayAdapter stringArrayAdapter = new ArrayAdapter(this, 
  android.R.layout.simple_spinner_dropdown_item, CatagoryName);

        // create a spinner
        Spinner spinner = (Spinner) findViewById(R.id.spinner);
        // add adapter to spinner
        spinner.setAdapter(stringArrayAdapter);
        // create listener and add to spinner
        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                // put code which recognize a selected element
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });

基本上，我想在

使用我的自定义微调器布局

   ArrayAdapter stringArrayAdapter = new ArrayAdapter(this, 
   android.R.layout.simple_spinner_dropdown_item, CatagoryName);

R.layout.simple_spinner_dropdown 不是我想要的。如何用我的替换这个布局？

Answer 1

试试这个方法：

    Spinner spinner = (Spinner) findViewById(R.id.spinner);
    String[] CatagoryName = {"A","B","C","D"};
    ArrayAdapter<CharSequence> langAdapter = new ArrayAdapter<CharSequence>(getActivity(), R.layout.your_layout, CatagoryName);
    langAdapter.setDropDownViewResource(R.layout.simple_spinner_dropdown);
    spinner.setAdapter(langAdapter);

Answer 2

这对我有用，首先在 strings.xml 中定义微调项，在上面的 values 目录中，

 
  <string-array name="spinner_array">
        <item>item1</item>
        <item>item2</item>
        <item>item3</item>
    </string-array>

然后尝试上面的代码，

 Spinner customSpinner = (Spinner)findViewById(R.id.spinner);

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getApplicationContext(), R.array.spinner_array, R.layout.custom_spinner_dropdown);

    customSpinner.setAdapter(adapter);
