Android无线网络使用无线键盘、触摸屏操作手机是如何进行的

这是我们为大家提供的一篇介绍Android无线网络使用无线键盘触摸屏操作手机是如何进行的的文章,接下来就让我们一起来了解一下吧!

Remote Droid

RemoteDroid是一个Android应用,能够让用户使用自己的无线网络使用无线键盘、触摸屏操作手机。这个项目为开发者提供了如网络连接、触摸屏手指运动等很好的样例。

Features requiring Android 2.0

Any features requiring Android 2.0 will probably necessitate a new branch, or possibly a new project to maintain compatibility with 1.6 devices.

Bluetooth

This is probably the most requested feature for RemoteDroid. It would eliminate the need for a server program, and enable use with the PS3.

Blocking issues

The author doesn't own an Android 2.0 device. (Oh, the pains of being an early adopter.)

Multitouch

Maybe the second most requested feature since the release of the Droid. It'd be useful for easier dragging and dropping (Currently, you have to tap and hold, or use the right alt key to toggle mouse buttons on or off.) and multi-finger gestures.

Blocking issues

The author still doesn't have an Android 2.0 device.

Networking

Zeroconf/Bonjour

IMHO, this is a nice to have, rather than a priority. Most people don't really care about IP addresses, so it'd be good to have an easier mechanism for connecting people's phones to their computers. If we can't have Bluetooth, we could at least have this.

Security/authentication

This requires a decent amount of thought before anything gets implemented.

Localization

Android is growing in popularity all over the world, and the rest of the world doesn't necessarily use the same characters that we do. Eventually, it'd be nice if RemoteDroid supported those.

Fun features

Bar code/QR code scanning

Someone recently suggested the addition of bar code/QR code scanning, probably using ZXing. This would just take the data from the code, and send it to the computer as a series of keypresses. It could be useful as a way of storing passwords, URLs, or whatever.

I'd probably implement it as another activity which could be reached by pressing the camera button. On successful scan, it's pass the data back to PadActivity, which would have some method added for turning a string into keypresses.

Wiimote-style motion control

This would either just use the accelerometer, or a combination of the accelerometer and the compass.

Blocking issues

The readings from both the accelerometer and the compass have a decent amount of noise. Techniques like Kalman filtering exist to reduce noise, but that requires me to figure out how to use them.
