获取选择器意图谷歌云端硬盘文件文档，而无需在Android中集成谷歌驱动器API

Question

我正在开发一个安卓应用程序，该应用程序在谷歌驱动器中调用getPickChooserIntent以获取一些文件，它对图像工作正常，但对文档不起作用：

注意：我不是在谈论谷歌驱动器API实现。

public static Intent getPickChooserIntent(
@NonNull Context context,
CharSequence title,
boolean includeDocuments,
boolean includeCamera) {
List<Intent> allIntents = new ArrayList<>();
PackageManager packageManager = context.getPackageManager();
// collect all camera intents if Camera permission is available
if (!isExplicitCameraPermissionRequired(context) && includeCamera) {
allIntents.addAll(getCameraIntents(context, packageManager));
}
List<Intent> galleryIntents =
getGalleryIntents(packageManager, Intent.ACTION_GET_CONTENT, includeDocuments);
if (galleryIntents.size() == 0) {
// if no intents found for get-content try pick intent action (Huawei P9).
galleryIntents = getGalleryIntents(packageManager, Intent.ACTION_PICK, includeDocuments);
}
allIntents.addAll(galleryIntents);
Intent target;
if (allIntents.isEmpty()) {
target = new Intent();
} else {
target = allIntents.get(allIntents.size() - 1);
allIntents.remove(allIntents.size() - 1);
}
// Create a chooser from the main  intent
Intent chooserIntent = Intent.createChooser(target, title);
// Add all other intents
chooserIntent.putExtra(
Intent.EXTRA_INITIAL_INTENTS, allIntents.toArray(new Parcelable[allIntents.size()]));
return chooserIntent;
}

从getPickImageChooserIntent(Context(获取所选图像的URI 将返回正确的 URI。

public static Uri getPickImageResultUri(@NonNull Context context, @Nullable Intent data) {
boolean isCamera = true;
if (data != null && data.getData() != null) {
String action = data.getAction();
isCamera = action != null && action.equals(MediaStore.ACTION_IMAGE_CAPTURE);
}
return isCamera || data.getData() == null ? getCaptureImageOutputUri(context) : data.getData();
}

之后，我只是找到URI：content://com.google.android.apps.docs.storage.legacy/enc%3D8HXM7NIDpCn_Ax78iaO3nB9azNXlIu4AOk2poROCD8xP19KU%0A

此 URI 适用于 ImageView 中的图像和显示图像，如果当时我选择 PDF 或其他文档，则它不起作用。

任何人都有任何想法在没有谷歌驱动器API集成的情况下从谷歌驱动器获取意图数据？

谢谢

终于我做到了！

溶液：

@Override
@SuppressLint("NewApi")
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CropImage.PICK_IMAGE_CHOOSER_REQUEST_CODE) {
if (resultCode == Activity.RESULT_OK) {

Uri mUri = CropImage.getPickImageResultUri(this, data);
writeStreamToFile(getApplicationContext(),mUri,".pdf");
}
}
}

方法：

@RequiresApi(api = Build.VERSION_CODES.KITKAT)
void writeStreamToFile(Context mContext, Uri mUri,String ext) {
if (mUri == null) {
return;
}
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = mContext.getContentResolver().query(mUri, filePathColumn, null, null, null);
String mCurrentPath = null;
if (cursor != null && cursor.moveToFirst()) {
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
mCurrentPath = cursor.getString(columnIndex);
cursor.close();
}
if (TextUtils.isEmpty(mCurrentPath)) {
mCurrentPath = mUri.getPath();
}
File storageDir = mContext.getExternalFilesDir(Environment.DIRECTORY_DOCUMENTS);
InputStream inputStream = null;
try {
inputStream = mContext.getContentResolver().openInputStream(mUri);
File file = File.createTempFile("pptFiles", ext, storageDir);
try (OutputStream output = new FileOutputStream(file)) {
byte[] buffer = new byte[4 * 1024]; // or other buffer size
int read;
while ((read = inputStream.read(buffer)) != -1) {
output.write(buffer, 0, read);
}
output.flush();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
