从字符串列表中填充一个 android 微调器

Question

我在将列表中的元素放入微调器时遇到问题。它给了我“应用程序已停止”。

这是代码：

private void connectToPC(){
        try {
            "..."
            String[] files = smbFile.list();

            for (String fileName : files) {
                Log.e("Test", "Fisier: " + fileName);
            }

            ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), R.id.fisierDate, files);
            fisierDate.setVisibility(View.VISIBLE);
            fisierDate.setAdapter(adapter);


        } catch (IOException e) {
            e.printStackTrace();
            Log.e("", "", e);
        }
    }

这是我在 Logcat 中遇到的错误：

connectToPC() 方法被称为按钮的onClick 事件。

我用过这个：Android : Fill Spinner From Java Code Programmatically

谢谢。

Answer 1

您使用了错误的 ArrayAdapter 构造函数。第二个参数应该是包含TextView id fisierDate的布局

改变

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), R.id.fisierDate, files);

与

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.layout_with_fisierDate, R.id.fisierDate, files);

Answer 2

您需要将字符串 disease_prompt 添加到您的 strings.xml。

Answer 3

您在资源 id R.id.fisierDate 附近的 .xml 布局文件中出现错误，请检查它是否正确并重试。
