Several of the previous articles have been ported by configuring DTS for multiple drives, and then we are addressing tq335x's touch-driven issues. For various reasons, tq335x touch screen drive is provided by the module, and the Linux official kernel also does not have the drive source code with the touchscreen, the simple configuration of DTS is unable to complete the tq335x touch-driven porting work, therefore, this article refers to the core of the

point device events, regardless of whether they occur within the window range. Public Static Final intFlag_not_touch_modal =0x00000020; If this flag is set, when the device sleeps, tap on the touchscreen and the device will receive this first touch event. Usually the first touch event is consumed by the system, and the user will not see what happens when they click on the screen. Public Static Final intFlag_touchable_when_waking =0x00000040; When

Reprinted from Http://www.cnblogs.com/xiaoweiz/p/3833079.htmlFirst, let's look at the definition of touch mode. It is a state of the view hierarchy when the user interacts with the phone. It's very easy to understand,Represents whether the most recent interaction occurred through a touchscreen, because there are other ways of interacting on Android devices, such as d-pad, scrolling balls, and so on.Why is Android introducing such a mode? This is becau

country number consists of three digits. Each country has its own independent MCC, which can identify the country to which the mobile phone user belongs. "Mnc" The IMSI mobile network code (MNC) has changed-that is, a SIM hasbeen detected and updated the MNC. mobile network number, which is used to differentiate mobile phone users in a country or region.

ObjectiveIf we allow users to control the Web APP in a way that is similar to a desktop browser mouse gesture on the page, there must be a lot of clickable areas on this page, what if the user touches those clickable areas??Mobile devices such as smartphones and tablets typically have a capacitive touchscreen (capacitive touch-sensitive screen) to capture the interaction of the user's finger. With the development of mobile networks, which can support

aregenerated by events and keystrokes that are usually generated by the touch screen and are the most common. But in fact inputevent not only have these two kinds. Because the android system can run a very rich type of device, on different devices corresponding to different hardware, there must be a different input events,inputevent Depending on the input source of the event, it can be divided into the following categories (not all):Sensor inputevent ( Transducer input Event )Hook inputevent (

Events such as Onclick,onlongclick,onfling,onscroll in Android are made up of multiple Ontouch events, and a complete touchscreen event must contain 1 Action_down (pressed), multiple action_ Move, 1 action_up (release), touch event distribution is the process by which these events rotate between viewgroup and view.1, ViewGroup inheritance View,view contains Dispatchtouchevent and ontouchevent two and event distribution directly related to two methods,
