我想更改 Android 上的 GifImageView 位置。通过使用 OnTouchListener 方法获取用户编织到屏幕中的点的位置。我想在 GifImageView 重定位中使用这个位置。你能帮助我吗?
gifImageView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
LayoutParams layoutParams = (LayoutParams) gifImageView.getLayoutParams();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
break;
case MotionEvent.ACTION_MOVE:
int x_cord = (int) event.getRawX();
int y_cord = (int) event.getRawY();
if (x_cord > windowwidth) {
x_cord = windowwidth;
}
if (y_cord > windowheight) {
y_cord = windowheight;
}
layoutParams.leftMargin = x_cord - 25;
layoutParams.topMargin = y_cord - 75;
gifImageView.setLayoutParams(layoutParams);
break;
default:
break;
}
return true;
}
});
我尝试使用上述代码更改位置,但包含此错误:
E/InputEventReceiver: Exception dispatching input event.
E/MessageQueue-JNI: Exception in MessageQueue callback: handleReceiveCallback
