我需要创建一个“滑动活动”,当用户滑动它时它会滑动。当用户向左“滑动”时,活动应向左滑动,新活动将从右侧进入屏幕。你不能把它放在中间。雅虎邮箱应用程序也是如此。您在阅读邮件时可以看到此信息,然后向左滑动邮件以转到下一封邮件。就像下面一样。
在图像中,您可以看到下一封邮件(标题为“谢谢”)从侧面打开。就我而言,它们是两种不同的活动。我们还可以在当前活动的右侧显示下一个活动的一小部分(例如在Windows手机中),这样用户就知道他必须刷卡。无论如何,这部分现在都是强制性的。
我尝试用this answer来做,但这不是我想要的。好吗?
注意
如果我选择片段,很多课程将被更改或完全重新编码。

请查看以下代码。在这里,当我在SalesInquiry.java
上滑动时,NewLead.java
应该是开放的,具有上述效果。

User GestureDetector and in onFling() method check for the direction of swipe and start the activity accordingly
Edited:
Try this:
GestureDetector gestureDetector = new GestureDetector(
simpleOnGestureListener);
SimpleOnGestureListener simpleOnGestureListener = new SimpleOnGestureListener() {
// Move The Background Theme To Select The Theme
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
float sensitvity = 100;
if ((e1.getX() - e2.getX()) > sensitvity) {
//Move right ,start new Activity here
return true;
}else if ((e2.getX() - e1.getX()) > sensitvity) {
//Move left ,start new Activity here
return true;
}else{
return false ;
}
}
@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
return (gestureDetector.onTouchEvent(event) || super
.onTouchEvent(event));
}

您可以简单地使用Fragments精确支持片段和ViewPager,它们可以让您浏览不同的片段。它在android.support.v4库中可用。
