startActivityForResult片段中不工作 [英] startActivityForResult Not Working in Fragment

问题描述

我尝试采取从图像相机或画廊购买其未设置的ImageView

I try to take image from camera or gallery buy its not set on imageView

`公共类NewPatient扩展片段{
    按钮Takeimage，保存，取消;
    INT REQUEST_CAMERA = 0，SELECT_FILE = 1;
    ImageView的imageview1;
    乌里imageUri;
    私人位图位图;
    MediaPlayer的熔点为新的MediaPlayer（）;
    @覆盖
    公共查看onCreateView（LayoutInflater充气器，容器的ViewGroup，捆绑savedInstanceState）{
        查看myFragmentView = inflater.inflate（R.layout.activity_new_patient，集装箱，FALSE）;

`public class NewPatient extends Fragment { Button Takeimage, save, cancel; int REQUEST_CAMERA = 0, SELECT_FILE = 1; ImageView imageview1; Uri imageUri; private Bitmap bitmap; MediaPlayer mp = new MediaPlayer(); @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View myFragmentView = inflater.inflate(R.layout.activity_new_patient, container, false);

    imageview1 = (ImageView) myFragmentView.findViewById(R.id.imageNP);
    Takeimage = (Button) myFragmentView.findViewById(R.id.takeimg);
    save = (Button) myFragmentView.findViewById(R.id.save);
    cancel = (Button) myFragmentView.findViewById(R.id.cancel);

    Pakage = (Spinner) myFragmentView.findViewById(R.id.packages);
    Takeimage.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            selectImage();
        }

    return myFragmentView;

private void selectImage() {
    final CharSequence[] items = { "Take Photo", "Choose from Library",
            "Cancel" };

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setTitle("Add Photo!");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int item) {

                dialog.dismiss();
            }

    });

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

    if (resultCode == Activity.RESULT_OK) {
        if (requestCode == SELECT_FILE)
            onSelectFromGalleryResult(data);
        else if (requestCode == REQUEST_CAMERA)
            onCaptureImageResult(data);
    }
}

private void onCaptureImageResult(Intent data) {
    Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);

    File destination = new File(Environment.getExternalStorageDirectory(),
            System.currentTimeMillis() + ".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();
    }

    imageview1.setImageBitmap(thumbnail);
}

@SuppressWarnings("deprecation")
private void onSelectFromGalleryResult(Intent data) {
    Uri selectedImageUri = data.getData();
    String[] projection = { MediaColumns.DATA };
    Cursor cursor = getActivity().managedQuery(selectedImageUri, projection, null, null,
            null);
    int column_index = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
    cursor.moveToFirst();

    String selectedImagePath = cursor.getString(column_index);

    Bitmap bm;
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(selectedImagePath, options);
    final int REQUIRED_SIZE = 200;
    int scale = 1;
    while (options.outWidth / scale / 2 >= REQUIRED_SIZE
            && options.outHeight / scale / 2 >= REQUIRED_SIZE)
        scale *= 2;
    options.inSampleSize = scale;
    options.inJustDecodeBounds = false;
    bm = BitmapFactory.decodeFile(selectedImagePath, options);

    imageview1.setImageBitmap(bm);
}`

是什么问题，我无法理解。
遗憾的英语不好

what is problem i can't understand. sorry for bad English

推荐答案

这code为浏览

case R.id.take_pic:
        startActivityForResult(new Intent(
                android.provider.MediaStore.ACTION_IMAGE_CAPTURE),
                TAKE_REQUEST);
        break;
    case R.id.browse_pic:

        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        startActivityForResult(intent, SELECT_REQUEST);
        break;

在onActivity结果

in onActivity result

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == TAKE_REQUEST && resultCode == Activity.RESULT_OK) {
        pic = (Bitmap) data.getExtras().get("data");
        imageView.setImageBitmap(pic);

    }
    if (requestCode == SELECT_REQUEST && resultCode == Activity.RESULT_OK) {
        try {
            InputStream stream = getActivity().getContentResolver()
                    .openInputStream(data.getData());
            pic = BitmapFactory.decodeStream(stream);
            stream.close();
            imageView.setImageBitmap(pic);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
