Question

我想从手机中选择多张图片，但我只获得1张图片，现在我正在使用意图

Intent intent = new Intent();         
intent.setType("image/*");        
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);

但它仍然只选择一个图像。所以如何设置图像选择的限制超过1以及如何在onActivityResult中处理它。

Answer 1

首先，您需要对多个图像执行哪些操作，这很重要

其次，你可以使用数组列表作为相同的位图数组列表，并进一步传递该列表，你可以从该列表中访问所有图像..请尝试并恢复..

尝试以下代码：

      Intent intent = new Intent();
      intent.setType("image/*");
      intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
      intent.setAction(Intent.ACTION_GET_CONTENT);
      startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);

//覆盖onActivityResult方法

                 @Override
                  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
                   if(requestCode ==1)
                  if (data != null) {
                    ClipData clipData = null;
                    try {
                         clipData = data.getClipData();
                        } catch (Exception exception) {
                           e.printStackTrace();
                         }
                      if (clipData != null) {
                        for (int i = 0; i < clipData.getItemCount();i++) {
                             // Get Uri for the image
                         Uri selectedImage = data.getClipData().getItemAt(i).getUri();
                      try {
                      String imagePath = getRealPathFromURI(selectedImage, this); /* Do whatever you want to do with imagePath */
                          } 
                         catch (Exception e) {
                                e.printStackTrace();
                           }
                         }
                     }
                   }
                }
              }

    private String getRealPathFromURI(Uri contentURI, Context context) {
    String filePath = "";

    Pattern p = Pattern.compile("(\\d+)$");
    Matcher m = p.matcher(contentURI.toString());
    if (!m.find()) {
        Log.e("", "ID for requested image not found: " +       contentURI.toString());
        return filePath;
    }
    String imgId = m.group();

    String[] column = { MediaStore.Images.Media.DATA };
    String sel = MediaStore.Images.Media._ID + "=?";

        Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                column, sel, new String[]{imgId}, null);

        int columnIndex = cursor.getColumnIndex(column[0]);

        if (cursor.moveToFirst()) {
            filePath = cursor.getString(columnIndex);
        }
        cursor.close();

    return filePath;


}
