我正在尝试使用ObjectAnimator在android中移动按钮。我希望视图能够移动，以便它不会与前一个位置重叠，也不会重叠。所以，当按下按钮时，我计算新的位置，如new_location = Current_location_of_view + view_height。当移动时：new_location = Current_location_of_view + view_height。但为了正常工作，我必须向上添加24dp（72p）的偏移量，在获取当前视图的位置时，通过减去72来实现此目的。这个抵消来自哪里？ 我的猜测是view.getLocationOnScreen（）函数与ObjectAnimator.ofFloat（view，“y”，new_location）函数有不同的y轴起点，但我不知道为什么。这应该如何正确完成？使用objectAnimator在Android上移动视图，获得24dp（72p）的偏移量
我使用这个代码：
private void moveViewUpMinimum(View view, int viewHeight){
int currentViewLocation = getViewLocation(view);
Log.e("Actual location", String.valueOf(currentViewLocation));
if(currentViewLocation >viewHeight){
//if there is enough space on top of the screen
ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(view, "y", currentViewLocation-viewHeight);
Log.e("Set location:", String.valueOf(currentViewLocation-viewHeight));
objectAnimator.setDuration(100);
objectAnimator.start();
}
else{
//if no more room move the view down
ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(view, "y", screenHeight-viewHeight);
objectAnimator.setDuration(100);
objectAnimator.start();
}
}
private void moveViewDownMinimum(View view, int viewHeight){
int currentViewLocation = getViewLocation(view);
Log.e("Actual location", String.valueOf(currentViewLocation));
if(screenHeight - currentViewLocation >= 2*viewHeight){
//if there is enough space on the bottom of the screen
ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(view, "y", currentViewLocation+viewHeight);
Log.e("Set location:", String.valueOf(currentViewLocation+viewHeight));
objectAnimator.setDuration(100);
objectAnimator.start();
}
else{
//if no more room move the view up
ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(view, "y", 0);
objectAnimator.setDuration(100);
objectAnimator.start();
}
}
private int getViewLocation(View view){
int buttonLoc[] = {0, 0};
view.getLocationOnScreen(buttonLoc);
return buttonLoc[1]-72;//where does this offset come from???
}
