的buttonDown和ButtonUp事件为Android屏幕按钮？ [英] ButtonDown and ButtonUp events for Android screen buttons?

问题描述

有没有办法得到一个onButtonDown或onButtonUp事件的软按钮（即不是一个物理硬件按钮，但屏幕上的按钮）？我有，我希望用户按住X秒，屏幕上的按钮。要做到这一点，我需要单独捕获的buttonDown和buttonUp事件。

谢谢

解决方案

  yourButton.setOnTouchListener（yourListener）;

公共布尔onTouch（查看yourButton，MotionEvent theMotion）{
    开关（theMotion.getAction（））{
    案例MotionEvent.ACTION_DOWN：打破;
    案例MotionEvent.ACTION_UP：打破;
    }
    返回true;
}
 

Is there a way to get an onButtonDown or onButtonUp event for a soft button (i.e. not a physical hardware button, but a button on the screen)? I have a button on the screen that I want the user to hold down for X seconds. To do this I need to capture the buttonDown and buttonUp events separately.

Thanks,

Bret

解决方案

yourButton.setOnTouchListener( yourListener );

public boolean onTouch( View yourButton , MotionEvent theMotion ) {
    switch ( theMotion.getAction() ) {
    case MotionEvent.ACTION_DOWN: break;
    case MotionEvent.ACTION_UP: break;
    }
    return true;
}
