我正在尝试在我的 FrameLayout 中制作可 move 的文本。在 TextView 中，我设置了 OnTouchListener，您可以在下面看到它。问题是，当我触摸 textview(没有手指 move )时，OnTouchListener 给出了不同的位置，而我的 TextView 在不同的位置之间跳跃。我还放了 LogCat 结果，这与这种情况有关。感谢您的帮助。
onTouchListener = new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
Log.w("KKK", "ONTOUCH EVENT: "+motionEvent.getAction());
switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_DOWN:
ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
lastTouchX = motionEvent.getX();
lastTouchY = motionEvent.getY();
Log.w("KKK", "ACTION DOWN X: " + lastTouchX + " Y: " + lastTouchY);
break;
case MotionEvent.ACTION_MOVE:
Log.w("KKK", "ACTION MOVE BEFORE X: " + lastTouchX + " Y: " + lastTouchY);
float beforeX = lastTouchX, beforeY = lastTouchY;
lastTouchX = motionEvent.getX();
lastTouchY = motionEvent.getY();
Log.w("KKK", "ACTION MOVE AFTER X: " + lastTouchX + " Y: " + lastTouchY);
Log.w("KKK", "ACTION MOVE DELTA X: " + (beforeX - lastTouchX) + " Y: " + (beforeY - lastTouchY));
float delX = lastTouchX - beforeX;
float delY = lastTouchY - beforeY;
ViewGroup.MarginLayoutParams lp1 = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
lp1.setMargins(lp1.leftMargin+(int)delX, lp1.topMargin+(int)delY, lp1.rightMargin, lp1.bottomMargin);
view.setLayoutParams(lp1);
break;
}
return true;
};
};

最佳答案
解决方法:
我变了
motionEvent.getX();
到
motionEvent.getRawX();
与Y坐标法类似，
效果很好。
