Sélectionnez l'Image à partir de la galerie Android Fragment

L'utiliser pour ouvrir android image sélecteur:

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), GALLERY_INTENT_CALLED);
} else {
    Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType("image/*");
    startActivityForResult(intent, GALLERY_KITKAT_INTENT_CALLED);
}

et pour onActivityResult utiliser ceci:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Cursor cursor = null;
if (resultCode != Activity.RESULT_OK)
return;
if (data == null)
return;
Uri originalUri = null;
if (requestCode == GALLERY_INTENT_CALLED && data != null) {
originalUri = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
cursor = getActivity().getContentResolver().query(originalUri,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
filePath = cursor.getString(columnIndex);
cursor.close();
Log.d("path of uri", filePath);
} else if (requestCode == GALLERY_KITKAT_INTENT_CALLED && data != null) {
originalUri = data.getData();
final int takeFlags = data.getFlags()
& (Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
//Check for the freshest data.
getActivity().getContentResolver().takePersistableUriPermission(
originalUri, takeFlags);
Log.d("Uri: ", originalUri.toString());
filePath = getPath(getActivity(), originalUri);
Log.d("filepath", filePath);
}
}

utiliser ce code pour choisir l'image,

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select image"),
PICK_IMAGE);

Puisque l'Activité est le résultat de onActivityResult(), vous devrez remplacer l'activité onActivityResult() et d'appeler super.onActivityResult() pour se propager à l'fragment de non gérée résultats de codes ou pour tous.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
