Je dois enregistrer les photos prises avec mon application dans un dossier spécifique. J'ai lu de nombreuses solutions à ce problème, mais je n'ai pu en faire fonctionner aucune, alors je demande de l'aide.
MainActivity.Java
public void onClick(View v) {
Intent camera = new Intent(
Android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
//Folder is already created
String dirName = Environment.getExternalStorageDirectory().getPath()
+ "/MyAppFolder/MyApp" + n + ".png";
Uri uriSavedImage = Uri.fromFile(new File(dirName));
camera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(camera, 1);
n++;
}
AndroidManifest.xml
<uses-permission Android:name="Android.permission.CAMERA" />
<uses-permission Android:name="Android.permission.WRITE_EXTERNAL_STORAGE" />
Parcourez le code suivant, cela fonctionne bien pour moi.
private void createDirectoryAndSaveFile(Bitmap imageToSave, String fileName) {
File direct = new File(Environment.getExternalStorageDirectory() + "/DirName");
if (!direct.exists()) {
File wallpaperDirectory = new File("/sdcard/DirName/");
wallpaperDirectory.mkdirs();
}
File file = new File("/sdcard/DirName/", fileName);
if (file.exists()) {
file.delete();
}
try {
FileOutputStream out = new FileOutputStream(file);
imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
J'ai utilisé le code de mdDroid comme ceci:
public void startCamera() {
// Create photo
newPhoto = new Photo();
newPhoto.setName(App.getPhotoName());
//Create folder !exist
String folderPath = Environment.getExternalStorageDirectory() + "/PestControl";
File folder = new File(folderPath);
if (!folder.exists()) {
File wallpaperDirectory = new File(folderPath);
wallpaperDirectory.mkdirs();
}
//create a new file
newFile = new File(folderPath, newPhoto.getName());
if (newFile != null) {
// save image here
Uri relativePath = Uri.fromFile(newFile);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, relativePath);
startActivityForResult(intent, CAMERA_REQUEST);
}
}
Utilisez comme ça. Cela fonctionnera pour vous.
public void onClick(View v) {
Intent camera = new Intent(
Android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(camera, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case 1:
if(resultCode == RESULT_OK) {
Uri selectedImage = imageReturnedIntent.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
//file path of captured image
filePath = cursor.getString(columnIndex);
//file path of captured image
File f = new File(filePath);
filename= f.getName();
Toast.makeText(getApplicationContext(), "Your Path:"+filePath, 2000).show();
Toast.makeText(getApplicationContext(), "Your Filename:"+filename, 2000).show();
cursor.close();
//Convert file path into bitmap image using below line.
// yourSelectedImage = BitmapFactory.decodeFile(filePath);
Toast.makeText(getApplicationContext(), "Your image"+yourSelectedImage, 2000).show();
//put bitmapimage in your imageview
//yourimgView.setImageBitmap(yourSelectedImage);
Savefile(filename,filePath);
}
}
}
public void Savefile(String name, String path) {
File direct = new File(Environment.getExternalStorageDirectory() + "/MyAppFolder/MyApp/");
File file = new File(Environment.getExternalStorageDirectory() + "/MyAppFolder/MyApp/"+n+".png");
if(!direct.exists()) {
direct.mkdir();
}
if (!file.exists()) {
try {
file.createNewFile();
FileChannel src = new FileInputStream(path).getChannel();
FileChannel dst = new FileOutputStream(file).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
J'espère que ceci vous aidera. pour référence à utiliser camera intention.
