Android-使用相机意图拍摄照片以供临时使用

Question

我正在使用内置相机意图拍照，我的应用只需要图像来创建一个位图。是否可以在不创建我自己的自定义相机的情况下避免将图像保存到画廊？这是我当前的拍照代码。

public void open() {
    Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, 1);
}
static Bitmap bp;

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    bp = (Bitmap) data.getExtras().get("data");
    onNavigationDrawerItemSelected(currentPosition);

    }

不，但你可以删除它，试试这个代码：

 private void DeletePicTaken(){
            final String[] imageColumns = { BaseColumns._ID, MediaColumns.DATA };
            final String imageOrderBy = BaseColumns._ID + " DESC";
            Cursor imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns, null, null, imageOrderBy);
            if(imageCursor.moveToFirst()){
                //int id = imageCursor.getInt(imageCursor.getColumnIndex(MediaStore.Images.Media._ID));
                String fullPath = imageCursor.getString(imageCursor.getColumnIndex(MediaColumns.DATA));
                //imageCursor.close();
                File file = new File(fullPath);
                file.delete();
            }


        } 

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    bp = (Bitmap) data.getExtras().get("data");
    onNavigationDrawerItemSelected(currentPosition);
    DeletePicTaken();
    }
