问题 I'm using the CameraPreview example API demo. I need to add some views (button, etc..) overlaying the SurfaceView. For this, I'm trying to set their parameters, but they appear all the time on the top-left side of the screen. This is the onCreate method of the code: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); btnTakePhoto = new

问题 jQuery.param() takes an array of key-value pairs, and turns it into a string you can use as a query string in HTML requests. For example, a = { userid:1, gender:male } would get converted to userid=1&gender=male I'm trying to call external APIs on the server side in a Google Apps script, which need long query strings. I would use the jQuery param function, but there seems to be no easy way to use jQuery on the server side in Google. Could you give me plain javascript code that achieves the

问题 I like all the default routes that are generated by Rail's map.resources . But, there are cases where I would like to use a non-numeric identifier in my routes. For example, If have a nested route consist of users and their articles, a standard route could be written as such: map.resources :users, :has_many => [:articles] # => e.g. '/users/:id/articles/:id' However, there are many advantages / reasons not to use the default numerical identifier generated by Rails. Is there a way to replace

问题 I'm using a GSP for sending out emails based on the MailService plug-in. The sendMail closure passes (amongst others) body(view:..., model:myModel) I know that I can access every item of the myModel Map just using ${itemName} in the GSP.
