android - giving onTouch priority over onClick

由 混江龙づ霸主 提交于 2019-12-30 10:48:09
问题 I have an activity that allows users to swipe between 3 different views. Each view displays a list of images. The images have onClick events that call a new activity and makes the images full screen. This all works ok however if I try to swipe between the 3 different views and my finger swipes over an image it will trigger the onClick event and open the image fullscreen. So I am wondering how can I put priority on onTouch (for the page/view swapping) ? (the onTouch event uses a

问题 so i've done some searching but haven't found a good answer. anyone who's familiar with android 4.0 knows the fancy swipe to remove running apps. i'm trying to implement this into a dynamic list. when i say dynamic, it's a list being built with a base adapter and holder's. i'm wondering if anyone has a good example of how to implement this swipe feature into a dynamic list. i want it to have the fancy animation and everything of the list collapsing back together after an element is removed.

问题 I've got a remove on swipe, that draws a background (much like the Inbox app), implemented by an ItemTouchHelper - by overriding the onChilDraw method and drawing a rectangle on the provided canvas: ItemTouchHelper mIth = new ItemTouchHelper( new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.RIGHT) { public void onSwiped(RecyclerView.ViewHolder viewHolder, int direction) { remove(viewHolder.getAdapterPosition()); } public boolean onMove(RecyclerView recyclerview, RecyclerView.ViewHolder v

Tutorial to implement the use of TabHost in Android 2.2 + ViewPager and Fragments

由 回眸只為那壹抹淺笑 提交于 2019-12-28 08:08:37
问题 A short tutorial for people like me who had some trouble finding a way to implement TabHost and ViewPager, including page swiping with fingers and tab click to change pages. The shown solution is compatible with Android versions 2.2+. It includes Tabs initialization, ViewPager connected with Tabs and Page Scrolling management. Its main peculiarity is the optimization for earlier versions of Android (Android 2.2 (Froyo), API version 8) and the simple implementation for different purposes. 回答1:

How to draw a Line in ImageView on Android?

由 三世轮回 提交于 2019-12-28 05:46:06
问题 I'd Like to know how to draw a Line on ImageView as user swipe their finger ? Could any body explain this ? Or perhaps any Link to get start on this. 回答1: You must have your own ImageView and override onDraw function. Use something like this public class MyImageView extends ImageView{ public MyImageView(Context context) { super(context); // TODO Auto-generated constructor stub } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); Paint p = new Paint(Paint.ANTI_ALIAS_FLAG);

Detect left/right-swipe on touch-devices, but allow up/down-scrolling

由 落花浮王杯 提交于 2019-12-28 04:49:07
问题 I need to detect and react to left/right-swipes, but want to give the user the ability to scroll on the same element, so as long as he moves his finger only left/right with a maximum up/down movement of X pixels, it should not scroll, but when he exceeds X, it should scroll. So what I did is: var startX, startY, $this = $(this); function touchmove(event) { var touches = event.originalEvent.touches; if (touches && touches.length) { var deltaX = touches[0].pageX - startX; var deltaY = touches[0

gulp实时编译less，压缩合并requirejs模块文件

gulp的使用命令简单，就几个，gulp的简单使用教材可以参考一点的gulp使用教材（http://www.ydcss.com/archives/18）。 下面就简单的介绍这些命令如何互相配合的完成前端的构建工作。 项目结构： 首先全局安装gulp，使用命令：npm install -g gulp 一：gulp实时编译less var gulp = require('gulp'); var gulpLess = require('gulp-less'); var gulpMinifyCss = require('gulp-minify-css'); var gulpSourcemaps = require('gulp-sourcemaps'); 　　这4个插件就是目前用到的，需要其他功能可以自己添加。gulp-less是编译less用的插件，gulp-minify-css是压缩css的插件，gulp-sourcemaps是便于压缩后代码调试的。 gulp.task('allLess', function(){ gulp.src('src/less/**/*.less') .pipe(gulpSourcemaps.init())//sourcemaps .pipe(gulpLess())//编译less .pipe(gulpSourcemaps.write()) .pipe(gulp

hammer.js - need default zoom behaviour + swipe

由 随声附和 提交于 2019-12-25 18:21:09
问题 I want to make it so swiping over an image will take a user to the previous or next image, depending on the direction of the swipe. That part works great, BUT it removes the ability to zoom in on the image. According to this answer the solution is to enable touchAction: 'auto' , but that breaks hammer.js entirely, preventing it from working for swipe at all. Code: <script src="../js/hammer.min.js"></script> <script> $('.imagecontainer').each(function(){ var options = { touchAction: 'auto', };
