Can the Line chart be made adjustable on Android?

How can i use linechart adjustment function with android webview and able to move line correctly.

Well, I don't know what "webview" is but the Line chart can be made adjustable on Android phones, though the adjusting has to be custom and, because of the limitations of the interface, only a single line is supported.

I've made you a demo of how to do it here:
