android - 在接受的位置的基础上，如何显示图像？

Question

public class ImageViewActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {

        Integer[] ImgPreview = { R.drawable.mlview1, R.drawable.mlview2,
            R.drawable.mlview3 };
        super.onCreate(savedInstanceState);
        setContentView(R.layout.image_prev);

        Intent intent = null;
        Bundle b = intent.getExtras();
        int position = b.getInt("position");

        // here, what to do?
        if (position == 0) {

        }

从上一个活动中，它获取参数“位置”，根据“位置”的值，它应该显示图像。例如：如果位置为 0，则显示图像“mlview1”，依此类推。

写这个。。

ImageView imageView = (ImageView) findViewById(R.id.imageview); // Here R.id.imageview is id of ImageView fro your image_prev xml file.. change according it..
imageView.setImageResource(ImgPreview[position]);
