Android Speedometer (Needle Gauge)

问题:

Creating a simple app that calculates the speed your going and displays it in a speedometer graphic. I can do all the speed calculations, gps calculations etc.. but i am not too sure about the animation. Does anyone have any good tutorials or examples on needle gauges other than the thermometer example out there?

回答1:

You could probably start with something like this.

Then when transitioning between values, do an animation where the needle gradually moves to the next value X units per unit of time.

This question is also very similar to yours.

I know, the post is quite old. But I had the same situation: there is no a good control for representing speed. I guess many people are facing this.

I've implemented SpeedometerView myself: a simple speedometer with needle and colored value ranges. Feel free to download!

This control was used in my app CardioMood.

The code is not optimized, but works. Enjoy!

Check here. It is my code. If you have any question please let me know. Visit https://github.com/mucahitsidimi/GaugeView

You can implement Gauge to your project simply.

<com.sidimi.mucahit.gaugeview.GaugeView
android:id="@+id/gaugeView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>

You can set width and height what ever you want to. It will calculate everything automatically.
