onItemSelected 用于字符串数组

Question

I want to make a spinner that has a list, and when selected an imageView bellow it will change getting its value form its integer-array and also change a TextView that also gets its value from a string-array.

现在我已经完成了其中的 2 个，并且它有效（微调器和改变它下面的图像）。问题是让 TextView 发生变化。当我运行它只是崩溃的应用程序

我的java代码：

imgs = getResources().obtainTypedArray(R.array.wakafimage);
image = (ImageView) findViewById(R.id.senaraiwakafimage);
nos = getResources().obtainTypedArray(R.array.nosijil);
tnos = (TextView)findViewById(R.id.sno);

dynamicSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view,
                                   int position, long id) {
            image.setImageResource(imgs.getResourceId(
                    dynamicSpinner.getSelectedItemPosition(), -1));

            tnos.setText(nos.getResourceId(
                    dynamicSpinner.getSelectedItemPosition(), -1));

我的string.xml:

<string-array name="wakaf">
    <item>Pembinaan Sekolah Agama di Seluruh Negeri Johor</item>
    <item>Wakaf Bangunan Darul Furqan</item>
    <item>Wakaf Bangunan Kompleks Tahfiz Kluang</item>
    <item>Wakaf Pembelian Mesin Hemodialisis</item>
    <item>Wakaf Bangunan Asrama Pelajar di Jordan</item>
</string-array>

<string-array name="nosijil">
    <item>2015000149861</item>
    <item>2015000149862</item>
    <item>2015000149863</item>
    <item>2015000149864</item>
    <item>2015000149865</item>
</string-array>

<integer-array name="wakafimage">
    <item>@drawable/wsekolah</item>
    <item>@drawable/wfurqan</item>
    <item>@drawable/wtahfiz</item>
    <item>@drawable/wmesin</item>
    <item>@drawable/wasrama</item>

问题出在这里，当我删除它时应用程序运行正常。

tnos.setText(nos.getResourceId(
                    dynamicSpinner.getSelectedItemPosition(), -1));

我是 android 的新手，这也是我的第一个问题，抱歉英语不好，在此先感谢。
