如何在Android Gallery上顯示相機？

Question

Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI); 
startActivityForResult(i, 2); 

當我使用這些行從設備庫中選擇圖像時，默認情況下，“取消”按鈕顯示在設備庫屏幕的標題欄上。 在取消按鈕的位置，我要顯示相機圖像，請問有人可以建議我如何顯示相機

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);

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

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

            Bitmap bmpp = decodeAndResizeFile(file);
            imgview.setImageBitmap(bmpp);


        }
    }



    public Bitmap decodeAndResizeFile(File f) {
        try {

            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 Camera應用程序的布局獨立於其他應用程序的。 它將根據設備和API進行更改。 您無法更改默認相機應用程序的布局設計。

如果需要，您可以創建自己的布局並自行打開相機。
