无需Android中的Google Drive Api集成,即可获取具有Pick Chooser意图的Google Drive文件文档
我正在开发一个android应用程序,它在google drive中调用GetPickChooserContent来获取一些文件,它可以处理图像,但不能处理文档: 注意:我不是在谈论GoogleDriveAPI的实现无需Android中的Google Drive Api集成,即可获取具有Pick Chooser意图的Google Drive文件文档,android,android-intent,document,google-drive-android-api,Android,Android Intent,Document,Google Drive Android Api,我正在开发一个android应用程序,它在google drive中调用GetPickChooserContent来获取一些文件,它可以处理图像,但不能处理文档: 注意:我不是在谈论GoogleDriveAPI的实现 public static Intent getPickChooserIntent( @NonNull Context context, CharSequence title, boolean includeDocuments, bo
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;
}
在这之后,我只找到类似这样的URI:content://com.google.android.apps.docs.storage.legacy/enc%3D8HXM7NIDpCn_Ax78iaO3nB9azNXlIu4AOk2poROCD8xP19KU%0A
这个URI对于图像和在ImageView中显示图像工作正常,如果当时我选择了PDF或其他文档,那么它就不工作了
有人有没有想过在没有google drive API集成的情况下从google drive获取意向数据
谢谢我终于做到了
解决方案:
@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();
}
}
}
你在用不起作用的uri做什么?我只想在我们的应用程序中下载该文件。然后显示该代码;PdfView:PdfView.fromUri(mUri);McRopimageri?
