Android - Enregistrer des images dans un dossier spécifique

J'ai besoin d'enregistrer les photos prises avec mon application dans un dossier spécifique. J'ai lu beaucoup de solutions à ce problème, mais je ne pouvais pas le faire tout de leur travail donc j'ai demander 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" />

    Passer par le code suivant , sa fonctionne très 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(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();
    }
}

    L'utilisation de ce genre. Il va travailler 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();
}
}
}

    Espère que cela va vous aider. pour la référence à utiliser caméra intention.

    J'ai utilisé mdDroid code 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);
}
}
