WP7 captures the slide direction of the screen (up or down)

Previously, touch was used. framereported is used to perform touch screen operations, but later it was found that some meticulous things could not be implemented. For example, the touchpoint action can only determine whether to click, move, and leave, so the sliding up or down is a solution.

After self-exploration, manipulationdelta is used to implement this function.

CodeAs follows:


Double firsty = 0.0; protected override void onmanipulationdelta (manipulationdeltaeventargs e) {If (firsty = 0.0) {firsty = E. cumulativemanipulation. translation. y;} else {double result = E. cumulativemanipulation. translation. y-firsty; If (result> 0) {This. dispatcher. begininvoke () => {MessageBox. show ("Move Down") ;}) ;}else if (result <0) {This. dispatcher. begininvoke () => {MessageBox. show ("Move Up") ;}) ;}firsty = 0.0 ;}base. onmanipulationdelta (E );}


[As follows]
