sincronizadas - ¿Cómo seleccionar múltiples imágenes de la galería en android?

gmail fotos sincronizadas

Question

Estoy haciendo un proyecto en el que quiero seleccionar varias fotos de la galería y quiero guardarlas en una matriz de vista de imagen. Puedo importar una sola imagen y guardar en la vista de imagen ¿Alguien puede saber cómo puedo importar varias imágenes y guardarlas en una matriz o en diferentes vistas de imagen?

MainActivity extends Activity implements OnClickListener {
Button addphoto, save;
ImageView img1[];
Bitmap yourbitmap, resized;
int RESULT_LOAD_IMAGE1 =1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addphoto = (Button)findViewById(R.id.add);
img1[0] = (ImageView)findViewById(R.id.imageView1);
save = (Button)findViewById(R.id.save);
addphoto.setOnClickListener(this);
save.setOnClickListener(this);
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch(arg0.getId()){
case R.id.add:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), RESULT_LOAD_IMAGE1);
break;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE1 && resultCode == RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
try {
yourbitmap = BitmapFactory.decodeFile(picturePath);
resized= Bitmap.createScaledBitmap(yourbitmap, 200,300, true);
img1[0].setImageBitmap(resized);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}

Aquí está el código para Seleccionar varias imágenes y videos de la Galería predeterminada.

Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Intent i = new Intent();
i.setType("image/*");
//i.setType("video/*");
i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
i.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(i, "android.intent.action.SEND_MULTIPLE"), 1);
}
});
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
System.out.println("++data" + data.getClipData().getItemCount());// Get count of image here.
System.out.println("++count" + data.getClipData().getItemCount());
Uri selectedImage = data.getClipData().getItemAt(0).getUri();//As of now use static position 0 use as per itemcount.
Bitmap bitmap = null;
// Uri selectedImage1 = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("+++ clipdate" + selectedImage);
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(bitmap);
// }
}

Answer 2

Creo que Android no admite la selección de varias imágenes. Para eso hay que usar alguna biblioteca. Yo también estaba atrapado en el mismo

https://github.com/luminousman/MultipleImagePick

este me ayudo

Answer 3

Hay EXTRA_ALLOW_MULTIPLE opción EXTRA_ALLOW_MULTIPLE establecida en la intención a través del método Intent.putExtra() :

 intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);

En su código escriba lo siguiente:

Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), RESULT_LOAD_IMAGE1);

Nota: la opción EXTRA_ALLOW_MULTIPLE solo está disponible en Android API 18 y superior .

Si desea desarrollar su propia galería, consulte la sección Seleccionar varias imágenes de la galería

Intención

 Intent intent = new Intent();
intent.setType("image/*");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
}
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_MULTIPLE);

Resultado de la actividad

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
// When an Image is picked
if (requestCode == PICK_IMAGE_MULTIPLE && resultCode == RESULT_OK
&& null != data && null != data.getClipData()) {
ClipData mClipData = data.getClipData();
Toast.makeText(getActivity(), "You picked " +

mClipData.getItemCount() + "Image"),
Toast.LENGTH_LONG).show();
pickedImageContainer.removeAllViews();
int pickedImageCount;
for (pickedImageCount = 0; pickedImageCount < mClipData.getItemCount();

productImageView.setLayoutParams(new LinearLayout

This is manifest file code for app to get consider you are sending images to your app
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.appshare"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<action
android:name="android.intent.action.SEND_MULTIPLE" />
<action
android:name="android.intent.action.SEND" />
<category
android:name="android.intent.category.DEFAULT" />
<data
android:mimeType="image/*" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Program code...
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d("MainActivity", "on Create ");
if (Intent.ACTION_SEND_MULTIPLE.equals(getIntent().getAction())&& getIntent().hasExtra(Intent.EXTRA_STREAM))
{
ArrayList<Parcelable> list =
getIntent().getParcelableArrayListExtra(Intent.EXTRA_STREAM);
for (Parcelable parcel : list) {
Uri uri1 = (Uri) parcel;
Log.d("MainActivity", "on Create uri1 " + uri1);
String sourcepath=getPath(uri1);
Log.d("MainActivity", "on Create sourcepath " + sourcepath);
/// do things here with each image source path.
}
//Commented by Aishwary coz I want to open the app after selecting images otherwise uncomment to just select
//finish();
}else{
// This part is of single image by Aishwary
Uri imageUri =(Uri) getIntent().getExtras().get(Intent.EXTRA_STREAM);
Log.d("MainActivity", "on Create ImageUri " + imageUri);
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
startManagingCursor(cursor);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
This will allow you to get source path and images url . Now you can make array for url and use this url as you want...
