seleccionar - la mejor galeria para android 2018

Diálogo para elegir la imagen de la galería o de la cámara

Question

¿Existe una forma estándar de llamar al cuadro de diálogo con elegir entre elegir una imagen de la cámara o la de la galería (como en la guía telefónica incorporada o Skype)?

He echado un vistazo a this pero el código abre la galería sin sugerir que se elija desde la cámara.

Dispositivo: Samsung Galaxy Tab
Android: 2.3.3

Answer 1

A continuación, el código se puede usar para tomar y seleccionar una foto, y para seleccionar una foto o tomar una foto. Simplemente muestre un diálogo con dos opciones y luego de la selección use el código apropiado.

Para tomar una foto de la cámara:

Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);//zero can be replaced with any action code

Para elegir una foto de la galería:

Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto , 1);//one can be replaced with any action code

Código onActivityResult :

protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case 0:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
imageview.setImageURI(selectedImage);
}
break;
case 1:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
imageview.setImageURI(selectedImage);
}
break;
}
}

Finalmente agregue este permiso en el archivo de manifiesto:

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Answer 2

Creo que depende de usted mostrar ese diálogo para elegir. Para la Galería usarás ese código, y para la cámara prueba this .

Answer 3

He fusionado algunas soluciones para hacer una utilidad completa para elegir una imagen de Galería o Cámara. Estas son las características de ImagePicker util gist (también en una lib de Github ):

• Intenciones fusionadas para las reclamaciones de la Galería y la Cámara.
• Cambiar el tamaño de las imágenes grandes seleccionadas (p. Ej .: 2500 x 1600)
• Girar imagen si es necesario

Captura de pantalla:

Editar : Aquí hay un fragmento de código para juntar un Intento combinado para las aplicaciones Galería y Cámara. Puede ver el código completo en ImagePicker util gist (también en una lib de Github ):

public static Intent getPickImageIntent(Context context) {
Intent chooserIntent = null;
List<Intent> intentList = new ArrayList<>();
Intent pickIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePhotoIntent.putExtra("return-data", true);
takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getTempFile(context)));
intentList = addIntentsToList(context, intentList, pickIntent);
intentList = addIntentsToList(context, intentList, takePhotoIntent);
if (intentList.size() > 0) {
chooserIntent = Intent.createChooser(intentList.remove(intentList.size() - 1),
context.getString(R.string.pick_image_intent_text));
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new Parcelable[]{}));
}
return chooserIntent;
}
private static List<Intent> addIntentsToList(Context context, List<Intent> list, Intent intent) {
List<ResolveInfo> resInfo = context.getPackageManager().queryIntentActivities(intent, 0);
for (ResolveInfo resolveInfo : resInfo) {
String packageName = resolveInfo.activityInfo.packageName;
Intent targetedIntent = new Intent(intent);
targetedIntent.setPackage(packageName);
list.add(targetedIntent);
}
return list;
}

Answer 4

Puede implementar este código para seleccionar la imagen de la galería o cámara: -

private ImageView imageview;
private Button btnSelectImage;
private Bitmap bitmap;
private File destination = null;
private InputStream inputStreamImg;
private String imgPath = null;
private final int PICK_IMAGE_CAMERA = 1, PICK_IMAGE_GALLERY = 2;

Ahora, al hacer clic en el evento, puede llamar a su método de seleccionar Imagen. Esto es dentro de la actividad onCreate.

imageview = (ImageView) findViewById(R.id.imageview);
btnSelectImage = (Button) findViewById(R.id.btnSelectImage);
//OnbtnSelectImage click event...
btnSelectImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
selectImage();
}
});

Fuera de tu actividad está en proceso de creación.

// Select image from camera and gallery
private void selectImage() {
try {
PackageManager pm = getPackageManager();
int hasPerm = pm.checkPermission(Manifest.permission.CAMERA, getPackageName());
if (hasPerm == PackageManager.PERMISSION_GRANTED) {
final CharSequence[] options = {"Take Photo", "Choose From Gallery","Cancel"};
android.support.v7.app.AlertDialog.Builder builder = new android.support.v7.app.AlertDialog.Builder(activity);
builder.setTitle("Select Option");
builder.setItems(options, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo")) {
dialog.dismiss();
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, PICK_IMAGE_CAMERA);
} else if (options[item].equals("Choose From Gallery")) {
dialog.dismiss();
Intent pickPhoto = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto, PICK_IMAGE_GALLERY);
} else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
} else
Toast.makeText(this, "Camera Permission error", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(this, "Camera Permission error", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
inputStreamImg = null;
if (requestCode == PICK_IMAGE_CAMERA) {
try {
Uri selectedImage = data.getData();
bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 50, bytes);
Log.e("Activity", "Pick from Camera::>>> ");
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
destination = new File(Environment.getExternalStorageDirectory() + "/" +
getString(R.string.app_name), "IMG_" + timeStamp + ".jpg");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
imgPath = destination.getAbsolutePath();
imageview.setImageBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
} else if (requestCode == PICK_IMAGE_GALLERY) {
Uri selectedImage = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 50, bytes);
Log.e("Activity", "Pick from Gallery::>>> ");
imgPath = getRealPathFromURI(selectedImage);
destination = new File(imgPath.toString());
imageview.setImageBitmap(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
}
}
public String getRealPathFromURI(Uri contentUri) {
String[] proj = {MediaStore.Audio.Media.DATA};
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

Atlast, finalmente agrega la cámara y escribe el permiso de almacenamiento externo en AndroidManifest.xml

Me funciona mucho, espero que también funcione para usted.

Answer 5

This biblioteca lo hace simple.

Solo llama:

PickImageDialog.on(MainActivity.this, new PickSetup(BuildConfig.APPLICATION_ID));

Luego haga que su Actividad implemente IPickResult y anule este método a continuación.

@Override
public void onPickResult(PickResult r) {
if (r.getError() == null) {
imageView.setImageBitmap(r.getBitmap());
//or
imageView.setImageURI(r.getUri());
} else {
//Handle possible errors
//TODO: do what you have to do with r.getError();
}
}

Si desea obtener la imagen de la galería o capturar la imagen y configurarla en la vista de la imagen en modo retrato, el siguiente código le ayudará a ...

En onCreate ()

title.setGravity(Gravity.CENTER);
title.setTextColor(Color.WHITE);
title.setTextSize(22);
AlertDialog.Builder builder = new AlertDialog.Builder(
AddContactActivity.this);
builder.setCustomTitle(title);
