layout

问题 Can you overlay a view on top of everything in android? In iPhone I would get the new view set its frame.origin to (0,0) and its width and height to the width and height of self.view . Adding it to self.view would then cause it to act as an overlay, covering the content behind (or if it had a transparent background then showing the view behind). Is there a similar technique in android? I realise that the views are slightly different (there are three types (or more...) relativelayout,

问题 MatPlotLib PyQt5 Layout Problems: Using horizontal and vertical layouts, it seems to be very difficult to get the widgets where I want them. Maybe there is another way of doing it, for instance: If one can put the canvas and toolbar in a container or some kind of widget. Then you can size it and put it where you want. If one can limit the size of the plot so that the UI in the background is visible. This seems impossible though. What about using QGridLayout? I have tried many things, but am

问题 I'm to implement a fullscreen layout for a Web app according to custom specs. I've got most of it under control but there's one part I have some trouble with. To economize on space in an otherwise already crowded GUI, a "Log out" button should go into the title row rather than elsewhere. The title row, of course, contains a title. The button should appear in its default dimensions for the given browser/opsys combination at the top right, with a little padding. The title should be centered in

问题 This question already has answers here : How do I prevent the padding property from changing width or height in CSS? (7 answers) Closed 5 years ago . I am starting to get in creating websites, but There are some things i don't understand. For example: I created a wrapperdiv. Inside it are three maindivs: header, content and footer. I gave the wrapperdiv a fixed size (1280px x 1024px) and set the content div to 2/3 of that size. The rest is 1/3. Now whenever i want to pad something inside my

问题 I have created a widget. I intentionally used layout_weight so it would fit any screen size. The widget is always spanned to 1X4. I now look at different devices in the graphic editor and I see the weight doesn't help. should I move to dip size? The linear-layouts are spanned differently in relation to the background image. My XML: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/app_widget_root" android:layout_width="fill_parent" android:layout_height

问题 I have a VerticalLayout filled with components in Vaadin. PLease i will to print this layout exactly as it is to an A4 paper. Any Idea how to do this, Code Sample will be great. 回答1: Straight out of the Vaadin doc… Printing the Browser Window Vaadin does not have special support for launching the printing in browser, but you can easily use the JavaScript print() method that opens the print window of the browser. Button print = new Button("Print This Page"); print.addClickListener(new Button

问题 I am trying to get my views to animate using MotionLayout but want certain Constraints to animate in before others. I think this was the purpose of the motion:staggered property for Transition but I don't understand how that works and there are no examples of it successfully working anywhere. With updated versions of MotionLayout it seems we should have motion:motionStagger for individual Constraints but again I cannot seem to get it to stagger as desired. Only documentation I could find was

问题 I am trying to have a custom GLSurfaceView with some text over it, to display the score in a game. I have made a uniform xml layout based off of someones post here but when I try to load it with a setContentView the app crashes. after debugging I found that it says "Source can not be found". I have rebuilt the R file but that doesn't help. For reference my class that extends GLSurfaceView is called GLView. Any help would be appreciated. package org.kizik.WLTBO; import android.app.Activity;
