Android - 以编程方式将文本从 strings.xml 添加到 TextView

Question

好的，所以我一直在学习教程 ( http://javatechig.com/android/android-spinner-example )，它是关于创建 Spinners 和动态添加图像(其位置在 strings.xml 文件中定义)到 View 。嗯，这很好，但我想扩展项目，以便我可以包含文本数组，再次在 strings.xml 文件中定义，以显示在图像之前和之后。我的代码如下，如您所见，我想用对我已经选择的微调项的引用替换 2 setText 行。有任何想法吗？感谢您的关注。

感谢大家的意见，我现在已经解决了这个问题，并在下面展示了一些关于我如何解决它的注释代码......

public class MainActivity extends Activity {

private ImageView image;
private String[] states;
private Spinner spinner1;
private TypedArray imgs;
private String[] leaders;
private String[] descrip;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    states = getResources().getStringArray(R.array.countries);
    imgs = getResources().obtainTypedArray(R.array.leader_photos);

    // --- The following lines grab the problematic string arrays defined in
    // strings.xml
    leaders = getResources().getStringArray(R.array.leaders);
    descrip = getResources().getStringArray(R.array.descrip);

    image = (ImageView) findViewById(R.id.leaderPhoto);
    spinner1 = (Spinner) findViewById(R.id.spinner1);

    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, states);
    dataAdapter
            .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner1.setAdapter(dataAdapter);

    spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent, View view,
                int position, long id) {

            // The variable index identifies what position the selected
            // spinner is. TextView text... locks to the TextView defined in
            // the activity_main.xml layout file. text.setText... loads the
            // appropriate value from the leaders string array
            int index = parent.getSelectedItemPosition();
            TextView text = (TextView) findViewById(R.id.tv1);
            text.setText(leaders[index]);

            image.setImageResource(imgs.getResourceId(
                    spinner1.getSelectedItemPosition(), -1));

            // See earlier comments above TextView tv1 for how this works
            TextView text2 = (TextView) findViewById(R.id.tv2);
            text2.setText(descrip[index]);

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {

        }

    });
}

Android - 以编程方式将文本从 strings.xml 添加到 TextView -

如果我理解你的意思对吗？

 Resources resources = context.getResources();

 String[] textString = resources.getStringArray(R.array.mytext);

然后您将文本放在字符串向量中 - 很容易放入 textView

然后在xml文件中

 <string-array name = "mytext"> 
    <item> ... text </item>
    <item> ... text</item>
    <item> ... text</item>
 </string-array>

在 textView 对象中

text.setText(textString[i]); // at position i
