通常的实现就是简单的用一个视图来处理所有的工作,并且在调用onCreateInputView的时候返回一个新的实例。那么你怎么知道该不该来显示你的输入视图呢,这个可以调用系统的 onEvaluateInputViewShow来测试是否需要,这个是系统根据当前的上下文环境来实现的。所以你的输入法状态改变的时候,就需要调用 updateInputViewShown来重...
Some input devices present multiple distinguishable sources of input. Applications can query the framework about the characteristics of each distinct source. As a further wrinkle, different kinds of input sources uses different coordinate systems to describe motion events. Refer to the comments on the ...
Alternately, it may be that the input devices are simply indistinguishable, such as two keyboards made by the same manufacturer. The input device descriptor returned by #getDescriptor should only be used when an application needs to remember settings associated with a particular input device. For ...
sockets[1]); return OK;}这里socketpair的创建与访问其实是还是借助文件描述符，WMS需要借助Binder通信向APP端回传文件描述符fd，这部分只是可以参考Binder知识，主要是在内核层面实现两个进程fd的转换，窗口添加成功后，socketpair
1、adb devices 查看设备 这个命令是查看当前连接的设备, 连接到计算机的android设备或者模拟器将会列出显示(如图) 只提示“List of devices attached” 没有罗列设备,两种情况下遇到过这个问题:(1)手机设置导致,确定手机已经连接到电脑上,且手机 “设置->开发者选项->开发人员选项”和“USB调试”为打开状态,在“是...

1. getevent命令能获取数据,说明input驱动层OK,且Eventhub.cpp层也能获取到数据 getevent命令打印数据格式:type=%d, code=%d, value=%d 2). dumpsysinput 可查看各个输入设备信息,包括设备对应的kl, kcm等信息, 以及当前指定的app信息 3). catproc/bus/input/devices 查所有input device信息 ...
