frmcamera.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent cameraIntent = new Intent(
                            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    startActivityForResult(cameraIntent, 1);

                }
            });
            frmalbumb.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent int_album = new Intent(Intent.ACTION_PICK);
                    int_album.setType("image/*");
                    startActivityForResult(int_album, 2);

                }
            });




            @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 1 && resultCode == RESULT_OK) {

            Bitmap photo = (Bitmap) data.getExtras().get("data");
            imgview.setImageBitmap(photo);

        } else if (requestCode == 2 && resultCode == RESULT_OK) {

            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();
            File file = new File(picturePath);
            Bitmap bmpp = decodeAndResizeFile(file);
            imgview.setImageBitmap(bmpp);


        }
    }



    public Bitmap decodeAndResizeFile(File f) {
        try {
            // Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(new FileInputStream(f), null, o);

            // The new size we want to scale to
            final int REQUIRED_SIZE = 70;

            // Find the correct scale value. It should be the power of 2.
            int width_tmp = o.outWidth, height_tmp = o.outHeight;
            int scale = 1;
            while (true) {
                if (width_tmp / 2 < REQUIRED_SIZE
                        || height_tmp / 2 < REQUIRED_SIZE)
                    break;
                width_tmp /= 2;
                height_tmp /= 2;
                scale *= 2;
            }
            BitmapFactory.Options o2 = new BitmapFactory.Options();
            o2.inSampleSize = scale;
            return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
        } catch (FileNotFoundException e) {
        }
        return null;
    }

AFAIK相机应用程序布局独立于其他应用程序。它将根据设备和API进行更改。您无法更改默认相机应用程序的布局设计。

如果您愿意，可以创建自己的布局并自行打开相机。

如何在Android画廊展示相机？
