在服务器上上传后，我想删除客户图像（从我保存在外部存储器中的相机中拍摄的图像）。 而且我正在使用FilePicker获取客户文档，它也具有相机选项。使用FilePicker获取文档后，在图库中可以看到图像，我不想。
如果我想对客户数据进行一些修改，这些图像在我的应用程序中仍然可用吗？ 。
有人可以帮助我吗？
我应该在哪里编写删除图片或文档的代码？
这里是用于从相机拍摄图像的代码。
if (view == takePicBtn) {
SelectImage();
}
private void SelectImage() {
final CharSequence[] items = {"Camera", "Cancel"};
AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
builder.setTitle("Add Image");
builder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
if (items[i].equals("Camera")) {
Intent intent = new
Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if
(intent.resolveActivity(getActivity().getPackageManager())
!= null) {
try {
photoFile = createImageFile();
} catch (IOException ioExp) {
}
if (photoFile != null) {
photoURI =
FileProvider.getUriForFile(getActivity(), "com.shery.safco",
photoFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT,
photoURI);
startActivityForResult(intent, REQUEST_CAMERA);
}
}
} else if (items[i].equals("Cancel")) {
dialogInterface.dismiss();
}
}
});
builder.show();
}
private File createImageFile() throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new
Date());
String imageFileName = "image_" + timeStamp + "_";
File storageDir =
activity.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".aaa", /* suffix */
storageDir /* directory */
);
filePaths = image.getAbsolutePath();
return image;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent
data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == REQUEST_CAMERA) {
Bitmap bitmap = CommonMethod.compressImage(photoFile,
getContext());
mCustomerImage = CommonMethod.bitmapToByteArray(bitmap);
imageTemplateStr = Base64.encodeToString(mCustomerImage,
Base64.DEFAULT);
imageCustomer.setImageBitmap(bitmap);
}
}
}
获取文档的代码。
else if (view == pickPhotoBtn) {
FilePickerBuilder.getInstance().setMaxCount(10)
.setActivityTheme(R.style.AppTheme3)
.pickPhoto(getActivity());
}
OnActivityResult（）方法。
@Override
public void onActivityResult(int requestCode, int resultCode, Intent
data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case FilePickerConst.REQUEST_CODE_PHOTO:
if (resultCode == Activity.RESULT_OK && data != null) {
Log.e(TAG, "onActivityResult: ");
for (String path :
data.getStringArrayListExtra(FilePickerConst.KEY_SELECTED_PHOTOS))
{
String fileName =
CommonMethod.getFileNameFromPath(path);
Log.e("DocPath : ", path);
if (!documentNameList.contains(fileName) &&
!selectPhotosPath.contains(path) && selectPhotosPath.size() < 10)
{
selectPhotosPath.add(path);
File file = new File(path);
Log.e(TAG, "Image Name: " + fileName);
documentNameList.add(fileName);
documentIdList.add(0);
selectPhotosBitmap.add(CommonMethod.compressImage(file,
getContext()));
}
}
adapter.addItems(selectPhotosBitmap);
adapter.notifyDataSetChanged();
Log.e(TAG, "Number Of Files: " +
selectPhotosPath.size());
}
}
}
用于上传文档的代码。
public void uploadDocument(final ArrayList<Document> documents) {
if (documents.size() == 0) {
if (progressDialog.isShowing())
progressDialog.dismiss();
imageCount = 1;
uploadGroupData();
return;
}
CommonMethod.writeToFile(new Gson().toJson(documents.get(0)));
// Log.d(TAG, "uploadDocument: For Debuging");
Document document = documents.get(0);
if (oldNic != null &&
!oldNic.equalsIgnoreCase(document.getNicNumber())) {
oldNic = document.getNicNumber();
documentCount = 1;
}
RequestParams params = new RequestParams();
params.put("document_count", documentCount);
params.put("document_data", new Gson().toJson(document));
/*params.put(Document.KEY_IMAGE_NAME, document.getImageName());
params.put(Document.KEY_IMAGE, document.getImage());
params.put(Document.KEY_LOAN_ID, document.getLoanId());
params.put(Document.KEY_DOC_ADDED_DATETIME,
document.getDocumentAddedDataTime());*/
//TODO Test URL For Debugging 2
PhpConnectivity.getClient().post(CommonConst.DOCUMENT_TEST_URL,
params, new AsyncHttpResponseHandler() {
@Override
public void onStart() {
super.onStart();
if (progressDialog.isShowing()) {
progressDialog.setMessage("Uploading Document " +
imageCount + " of " + imgTotalCount);
} else {
progressDialog.setTitle("Documents Sync Up");
progressDialog.setMessage("Uploading Document " +
imageCount + " of " + imgTotalCount);
progressDialog.setCancelable(false);
progressDialog.show();
}
}
@Override
public void onSuccess(int statusCode, Header[] headers, byte[]
responseBody) {
String response = new String(responseBody);
if (response.equalsIgnoreCase(RESPONSE_SUCCESS)) {
Log.e(TAG, "Document Sync Up Response: " + response);
imageCount++;
documentCount++;
documents.remove(0);
uploadDocument(documents);
} else {
Log.e(TAG, "Sync Up Failure: " + response);
progressDialog.dismiss();
CommonMethod.alert(SyncUpActivity.this
, "Document Sync Up Failure:", "Response: " +
response);
}
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[]
responseBody, Throwable error) {
if (responseBody == null) {
CommonMethod.alert(SyncUpActivity.this
, "Connectivity Error:", "Try Again!");
progressDialog.dismiss();
return;
}
String response = new String(responseBody);
Log.e(TAG, "onFailure: " + response);
CommonMethod.alert(SyncUpActivity.this
, "Document Sync Up Failure:", "Response: " +
response);
progressDialog.dismiss();
}
});
}
用于上传组数据的代码（与组数据一起发送的客户图像）
public void uploadGroupData() {
// Log.e(TAG, "group_data: "+ new Gson().toJson(groupSyncUpData));
CommonMethod.writeToFile(new Gson().toJson(groupSyncUpData));
RequestParams params = new RequestParams();
int id = dbHandler.getEmployeeID(preferences.getFirstname());
params.put("EmployeeId" , new Gson().toJson(id));
params.put("group_data", new Gson().toJson(groupSyncUpData));
Log.e("ParamsJason : ", ""+params);
//TODO Test URL For Debugging 1
PhpConnectivity.getClient().post(CommonConst.GROUP_TEST_URL, params,
new AsyncHttpResponseHandler() {
@Override
public void onStart() {
super.onStart();
progressDialog.setTitle("Group Sync Up");
progressDialog.setMessage("Group Data Uploading...");
progressDialog.setCancelable(false);
progressDialog.show();
}
@Override
public void onSuccess(int statusCode, Header[] headers, byte[]
responseBody) {
String response = new String(responseBody);
if (response.trim().equalsIgnoreCase(RESPONSE_SUCCESS)) {
progressDialog.dismiss();
CommonMethod.alert(SyncUpActivity.this
, "Group Sync Up:", "Success")
dbHandler.updateGroupSync(groupSyncUpData.getGroup().getGroupId(),
1);
recAdapter.getItemList().remove(groupSyncUpData.getGroup());
recAdapter.notifyDataSetChanged();
groupSyncUpData = null;
} else {
Log.e(TAG, "onFailure: " + response);
progressDialog.dismiss();
CommonMethod.alert(SyncUpActivity.this
, "Group Sync Up Failure:", "Response: " +
response);
}
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[]
responseBody, Throwable error) {
if (responseBody == null) {
CommonMethod.alert(SyncUpActivity.this
, "Connectivity Error:", "Try Again!");
progressDialog.dismiss();
return;
}
String response = new String(responseBody);
Log.e(TAG, "onFailure: " + response);
progressDialog.dismiss();
CommonMethod.alert(SyncUpActivity.this
, "Group Sync Up Failure:", "Response: " + response);
}
});
