在这里将一个浮动动作按钮,我具有由其中所有都包含在一个TABLayout多个片段共享如下所示如何通过图寻呼机

的FAB由所有共享的图寻呼机碎片。我想在FAB上添加一个onLongClicklistener,通过它我可以在布局上拖动按钮(包括viewPager)。 我已经使用onTouchListener和MotionEvent对象完成了上述任务。 但是,我无法使用拖放API(释放拖动的按钮后,该按钮消失)。
下面是代码:
orderIcon = (FloatingActionButton)findViewById(R.id.order_icon);
orderIcon.setTag(IMAGEVIEW_TAG);
// Sets a long click listener for the ImageView
orderIcon.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
ClipData.Item item = new ClipData.Item((CharSequence) v
.getTag());
String[] mimeTypes = { ClipDescription.MIMETYPE_TEXT_PLAIN };
ClipData clipData = ClipData.newPlainText("", "");
View.DragShadowBuilder myShadow = new View.DragShadowBuilder(view);
// Starts the drag
v.startDrag(clipData,myShadow,null,0);
return true;
}
});
orderIcon.setOnDragListener(new View.OnDragListener() {
@SuppressLint("NewApi")
@Override
public boolean onDrag(View v, DragEvent event) {
switch (event.getAction()) {
case DragEvent.ACTION_DRAG_STARTED:
owner = (ViewGroup) v.getParent();
owner.removeView(v);
Log.d(msg, "Action is DragEvent.ACTION_DRAG_STARTED");
break;
case DragEvent.ACTION_DRAG_ENTERED:
Log.d(msg, "Action is DragEvent.ACTION_DRAG_ENTERED");
float x = (int) event.getX();
float y = (int) event.getY();
break;
case DragEvent.ACTION_DRAG_EXITED:
Log.d(msg, "Action is DragEvent.ACTION_DRAG_EXITED");
x = (float) event.getX();
y = (float) event.getY();
v.setX(x);
v.setY(y);
owner.addView(v);
v.setVisibility(View.VISIBLE);
break;
case DragEvent.ACTION_DRAG_LOCATION:
Log.d(msg, "Action is DragEvent.ACTION_DRAG_LOCATION");
break;
case DragEvent.ACTION_DRAG_ENDED:
Log.d(msg, "Action is DragEvent.ACTION_DRAG_ENDED");
break;
case DragEvent.ACTION_DROP:
Log.d(msg, "ACTION_DROP event");
break;
default:
break;
}
return true;
}
});
任何响应将高度赞赏。先谢谢你。
这个工程,我不知道为什么它不是接受的答案,谢谢你 –
它实际上工作,但变量“视图”有错误。将其更改为“v”将使其工作。 –
@ChungXa谢谢,兄弟。 –
