从安卓图库中选择多张图片

 int PICK_IMAGE_MULTIPLE = 1;
String imageEncoded;
List<String> imagesEncodedList;
让我们假设 onClick 按钮应该打开图库以选择图像
 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"), PICK_IMAGE_MULTIPLE);
那么你应该重写 onActivityResult 方法
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    try {
        // When an Image is picked
        if (requestCode == PICK_IMAGE_MULTIPLE && resultCode == RESULT_OK
                    && null != data) {
            // Get the Image from data
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            imagesEncodedList = new ArrayList<String>();
            if(data.getData()!=null){
                Uri mImageUri=data.getData();
                // Get the cursor
                Cursor cursor = getContentResolver().query(mImageUri,
                            filePathColumn, null, null, null);
                // Move to first row
                cursor.moveToFirst();
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                imageEncoded  = cursor.getString(columnIndex);
                cursor.close();
            } else {
                if (data.getClipData() != null) {
                    ClipData mClipData = data.getClipData();
                    ArrayList<Uri> mArrayUri = new ArrayList<Uri>();
                    for (int i = 0; i < mClipData.getItemCount(); i++) {
                        ClipData.Item item = mClipData.getItemAt(i);
                        Uri uri = item.getUri();
                        mArrayUri.add(uri);
                        // Get the cursor
                        Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
                        // Move to first row
                        cursor.moveToFirst();
                        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                        imageEncoded  = cursor.getString(columnIndex);
                        imagesEncodedList.add(imageEncoded);
                        cursor.close();
                    Log.v("LOG_TAG", "Selected Images" + mArrayUri.size());
        } else {
            Toast.makeText(this, "You haven't picked Image",
                        Toast.LENGTH_LONG).show();
    } catch (Exception e) {
        Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
                    .show();
    super.onActivityResult(requestCode, resultCode, data);
请 注意： 画廊不提供选择多张图片的功能，因此我们在这里打开所有图片工作室，您可以从中选择多张图片。并且不要忘记将权限添加到您的清单中
非常重要： getData()；获取一张图片，如果用户选择多张图片，我将其存储在 imageEncoded String 中，那么它们应该存储在列表中
所以你必须检查哪个是空的才能使用另一个
