preview

问题 I customize my own soft keyboard by implementing the KeyboardView.OnKeyboardActionListener interface. When the keys are pressed, it will show a preview popup. My problem is how to disable the preview popup for special keys such as SHIFT and DELETE? I have tried to set the android:iconPreview attribute to null but it didn't work. <Key android:codes="-1" android:keyIcon="@drawable/key_shift" android:keyWidth="15%p" android:isModifier="true" android:isSticky="true" android:keyEdgeFlags="left" />

问题 I'm using Eclimd for completion. it generates a lot of helpful info about function, but in 1-line preview window it looks messy. (same window uses by omni-completion) So: Is there any way to change default preview window height? Make preview-popup instead of preview-window? 回答1: I am facing problems with 'previewheight' too so I came up with the following work around: set previewheight=50 au BufEnter ?* call PreviewHeightWorkAround() func PreviewHeightWorkAround() if &previewwindow exec

问题 I want to take the information typed into a text field and display it in a paragraph elsewhere on the page. Basically, exactly what is happening below as I'm type this (go to post a question and start typing in the main text box and you'll see what I mean). Any idea how to do this? The page has so much JavaScript on it I can't find how they did it. 回答1: I think you are looking for this. Here is how your html should look like: <textarea id="txt" style="width:600px; height:200px;"></textarea>

问题 I'm using Google's CameraPreview sample demo. Here, I have the cameraPreview, and an overlayed image over cameraPreview. When I take the photo, only the cameraPreview is saved, but I need the overlay image to be saved too over the cameraPreview. This is the way I save cameraPreview's photo, but I need to know what would be the best way for overlaying booth images and save them into one. public void onPictureTaken(byte[] data, Camera camera) { String photoPath = Environment

问题 I have created a custom camera preview view CameraView which extends SurfaceView , and it also implements SurfaceHolder.Callback interface. The view operates with the camera. When you open the view it shows a camera preview. On the same screen there is also overlay with two buttons - 'Take picture', 'Choose from gallery'. The activity that holds the CameraView releases and reopens the camera in onPause() and onResume() methods. If I click the 'Choose from gallery' button, the following intent

问题 I have done this using "pay" tools like ASPOSE, but I was curious if there are any open source tools out there that will do this. 回答1: I am sure there may be tools out there to do that, but if you can get the file into a format that can then be rasterized easily, it may be worth exploring that. eg converting the work doc to pdf then thumbnailing that. 来源： https://stackoverflow.com/questions/5921761/is-there-any-way-to-generate-a-thumbnail-image-of-a-docx-file

问题 I've been working on a simple Android app designed to pass streaming camera frames from the Android Camera2 API pipeline to my algorithm. I've made several applications already that faithfully do this using the Android Camera1 API, but even after checking (Google docs, forums) to confirm correct coding, I am unable to capture any real data from the ImageReader in onImageAvailable(). Please note the following relevant code: Setting up the ImageReaders: private void setUpCameraOutputs(int width

问题 According to the android camera docs from the Java SDK side, the camera preview frames have to be supplied a (visible and active) surface to be drawn to in order to access the frame data. I have linked a few of the things I have come across here (I'm new so capped at 2 hyperlinks), but I went over tons of documentation of various things before winding up posting my own question here on SO. My Problems: a) I explicitly don't want to draw the camera preview to the screen, I just want the byte

问题 I play around with the Preview M and test my app on it, especially the "saving a file to external storage" part. Before the download/save process starts, i request for Manifest.permission.WRITE_EXTERNAL_STORAGE permission as described on the developer page: https://developer.android.com/preview/features/runtime-permissions.html The dialog occurs as expected: "Allow <AppName> to access photos, media, and files on your device?" Deny / Allow If i hit the "deny"-button, the

问题 I have a dropzone.js instance on a web page with the following options: autoProcessQueue:false uploadMultiple:true parallelUploads:20 maxFiles:20 It is programmatically instantiated, as it is part of a larger form. I have it rigged up to process the queue when the form is submitted. The goal is for my users to be able to use the dropzone to manage images for an item, so I'd like them to be able to re-order the images by dragging and dropping the dropzone.js image previews. Is there a good way
