When customizing some controls, or using custom controls written by someone else, there are occasional multi-touch problems, so you need to disable Multitouch in some places, here are the two simple ways I found:1. Use the custom theme theme directly to modify the entire app's style to prohibit global multitouch: style name="Mythemestyle"> item NBSP; name = "Android:windowenablesplittouch" >
The gallery provided by the android source code does not support multi-touch features such as scaling images with two fingers, so you have to add the image by yourself.
The added code is simple. Just modify the rootlistener in/packages/apps/Gallery/src/COM/Android/camera/viewimage. java.
The following code calculates the scaling ratio based on the change of the distance length between two points:
Float sca
public class Scalegesturedetector extends Object
Java.lang.Object
Android.view.ScaleGestureDetector
class overviewDetects deformation gestures caused by multiple contacts (Multitouch), based on the received motionevent. The callback method Scalegesturedetector.onscalegesturelistener notifies the user when a specific gesture event occurs。 This class can only be used in conjunction with the motionevent triggered by the Touch
In the development of Android UI, we often encounter this requirement:Two components that support sliding, such as the ListView nested multiple Listview,listview item is a Viewpager or gallary? or ScrollView nested ScrollView and so on.In general, you may also need to support several features such as:¤ Two-layer components can slide¤ Do not let two components slide at the same time, or let two components sliding simultaneously and can adjust themselves¤ Click events that do not affect the sub vi
you have to report two times, the code setting delay is already 2ms, plus a pair of code, absolutely more than 3ms. so the delay from 1ms to 500us is reported when the packet is divided into 2 packets as follows: Else // other packages, set to 0 { delay_us (+); reportbuf[0; }finally still can not 5 points, 5 points directly disorderly report. It seems that the real firmware does not support 5 points, so read only 4 pointsFor (i=0;i{i

2) calculate the distance between two fingers in real time when the two fingers movesampledistant;
3) Calculate the scaling ratio:zoom= sampledistant / olddistant;
4) Repeat2,Step 3An up event occurs.

One of my friends once said that scaling and rotating an image on a multi-touch screen should be as basic as "Hello World" in the program. I think this is very reasonable. In the first part of the video (two parts in total), I will explain how to make the flex component rotate and zoom. The following class allows the image to be scaled and rotated, which is as classic as "Hello World" and also applies to vi
Cocoa Touch multi-languageImplementation is the content to be introduced in this article. When developing a project, you do not need to worry about the Display language. In the code, you need to call the display text everywhere:

The iphone's touchscreen is fairly easy to use, without hindrance, as Apple spends a lot of time dealing with the details of the smiles. You can use the built-in controls for free, but if you need to implement your own control, pay more attention to these details, otherwise the application may be extremely clumsy and difficult to use, and once you pay attention to these details, you may get a relaxed and natural iphone-like application.Finger Story: Design and implementation of
