如何获取使用相机拍摄的图像的图像路径？

Question

在我的应用程序中，您可以单击图像视图，该视图可让您选择从SD卡中选择图像或使用相机拍摄新照片。 我已经实现了从SD卡中选择图像的选项。现在我留下了相机选项。

我的问题：如何获取相机拍摄的任何新图像的图像路径？

下面是我用来打开对话框窗口的代码，以及从SD卡获取图像路径的方法。

1.这是对话框的代码：

private void showImageDialog() {
    final String [] items = new String [] {"From Camera", "From SD Card"};
    ArrayAdapter<String> adapter = new ArrayAdapter<String> (this, android.R.layout.select_dialog_item,items);
    AlertDialog.Builder builder = new AlertDialog.Builder(this);

    builder.setTitle("Select Image");
    builder.setAdapter( adapter, new DialogInterface.OnClickListener() {
        public void onClick( DialogInterface dialog, int item ) {
            if (item == 0) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                File file = new File(Environment.getExternalStorageDirectory(),
                                    "tmp_avatar_" + String.valueOf(System.currentTimeMillis()) + ".jpg");
                mImageCaptureUri = Uri.fromFile(file);

                try {
                    intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
                    intent.putExtra("return-data", true);

                    startActivityForResult(intent, PICK_FROM_CAMERA);
                } catch (Exception e) {
                    e.printStackTrace();
                }

                dialog.cancel();
            } else {
                Intent intent = new Intent();

                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);

                startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_FILE);
            }
        }
    } );

    final AlertDialog dialog = builder.create();
    dialog.show();
}

2.这是用于从SD卡图像获取图像路径的方法。

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == PICK_FROM_FILE || requestCode == PICK_FROM_CAMERA) {
            Uri selectedImageUri = data.getData();
            selectedImagePath = getPath(selectedImageUri);

            Log.v("IMAGE PATH====>>>> ",selectedImagePath);

            // Decode, scale and set the image.
            Bitmap myBitmap = BitmapFactory.decodeFile(selectedImagePath);
            Bitmap scaledBitmap = Bitmap.createScaledBitmap(myBitmap, NEW_WIDTH, NEW_HEIGHT, true);
            myBitmap.recycle();
            myBitmap = null;

            mImageView.setImageBitmap(scaledBitmap);
            mImageView.setTag(selectedImagePath);
        } 

    }
}
