意图库图像机器人位置和数组列表

Question

我正在使用意图将选定的图像从图像库发送到NextImage.java活动。我想将图像的选定位置和图像数组发送到下一个活动。我对意图感到困惑。

String[]imageUrls= new String[PostDetails.size()];
for (int index=0;index<imageUrls.length;index++){
       imageUrls[index]=PostDetails.get(index).getImag();
}

gallery = (Gallery) findViewById(R.id.img_gallery);
gallery.setAdapter(new ImagePagerAdapter(imageUrls));

gallery.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> gallery, View view, int position, long id) {

          Intent galleryIntent  = new Intent(ImageGalleryActivity.this, MyNextImage.class);
          galleryIntent.putExtra(imageUrls, position);
          startActivity(galleryIntent);
      }

在下一个图像类中：

private ViewPager pager;
String[] imageUrls;
private DisplayImageOptions options;
String images;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.view_flipper_item);
    Bundle bundle = getIntent().getExtras();
    String[] imageUrls = bundle.getStringArray(images);
    int pagerPosition = bundle.getInt(position, 0);

Answer 1

你把额外的东西放如下：

galleryIntent.putExtra("IMAGE_URLS", imageUrls);
galleryIntent.putExtra("POSITION", position);

并按如下方式获取额外内容：

String[] imageUrls = bundle.getStringArray("IMAGE_URLS");
int pagerPosition = bundle.getInt("POSITION", 0);
