How change position of popup menu on android overflow button?
提问by user3266062
I just like to implement somethings same as popup menu in the Gmail app, anchored to the overflow button at the top-right. for that I used the same code as google tutorial for android Android popup menu, but for me show pop menu on top of edge of actionbar not under that. If you notice on pop menu of gmail overflow you saw that popmenu take place at edge of actionbar.
我只是喜欢在 Gmail 应用程序中实现与弹出菜单相同的东西，锚定到右上角的溢出按钮。为此，我使用了与 android Android 弹出菜单的google 教程相同的代码，但对我来说，在操作栏的边缘显示弹出菜单而不是在它之下。如果您注意到 gmail 溢出的弹出菜单，您会看到弹出菜单发生在操作栏的边缘。
This is the xml that I used for popup menu:
这是我用于弹出菜单的 xml：
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/item1"
android:title="lablab"/>
<item
android:id="@+id/item2"
android:title="lablab"/>
</menu>
and at the follow is in my activity:
以下是我的活动：
public void showFontSetting(View view) {
PopupMenu popup = new PopupMenu(this, view);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.menu, popup.getMenu());
popup.show();
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.item1:
Toast.makeText(Index.this,
"You Clicked : " + item.getTitle(),
Toast.LENGTH_SHORT).show();
break;
case R.id.item2:
break;
}
return true;
}
});
}

Add the following piece of code to your activity:
将以下代码添加到您的活动中：
PopupWindow popupwindow_obj; // create object
popupwindow_obj=popupDisplay(); // initialize in onCreate()
popupwindow_obj.showAsDropDown(clickbtn,-40, 18); // where u want show on view click event
public PopupWindow popupDisplay() { // disply designing your popoup window
final PopupWindow popupWindow = new PopupWindow(this); // inflet your layout or diynamic add view
View view;
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.mylayout, null);
Button item = (LinearLayout) view.findViewById(R.id.button1);
popupWindow.setFocusable(true);
popupWindow.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
popupWindow.setContentView(view);
return popupWindow;
}
Create an XML in res/layoutdirectory and name it mylayout.xml
在res/layout目录中创建一个 XML并命名mylayout.xml
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Window test" />
</LinearLayout>

To overlap only, use this approach:
要仅重叠，请使用以下方法：
PopupMenu popupMenu = new PopupMenu(getContext(), this, Gravity.NO_GRAVITY, R.attr.actionOverflowMenuStyle, 0);
To get a PopupMenu with a bright background and a detailed control over the offsets use this approach:
要获得具有明亮背景和对偏移量的详细控制的 PopupMenu，请使用以下方法：
styles.xml
样式文件
<style name="PopupMenuOverlapAnchor" parent="@style/Theme.AppCompat.Light">
<item name="android:overlapAnchor">true</item>
<item name="android:dropDownVerticalOffset">0dp</item>
<item name="android:dropDownHorizontalOffset">0dp</item>
</style>
Code:
代码：
ContextThemeWrapper contextThemeWrapper = new ContextThemeWrapper(getContext(), R.style.PopupMenuOverlapAnchor);
PopupMenu popupMenu = new PopupMenu(contextThemeWrapper, this);
Does not work anymore:Here a simple way to adjust the position of a PopupMenu. It positions the menu over its anchor view (overflowButton) like the menu in the action bar:
不再起作用：这里有一个简单的方法来调整 a 的位置PopupMenu。它将菜单定位在其锚点视图 ( overflowButton) 上，就像操作栏中的菜单一样：
PopupMenu popupMenu = new PopupMenu(context, overflowMenuButton);
popupMenu.inflate(R.menu.my_menu);
// Fix vertical offset
overflowMenuButton.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
popupMenu.show();
if (popupMenu.getDragToOpenListener() instanceof ListPopupWindow.ForwardingListener)
{
ListPopupWindow.ForwardingListener listener = (ListPopupWindow.ForwardingListener) popupMenu.getDragToOpenListener();
listener.getPopup().setVerticalOffset(-overflowMenuButton.getHeight());
listener.getPopup().show();
}
}
});
PopupMenu popupMenu = new PopupMenu(context, overflowMenuButton);
popupMenu.inflate(R.menu.my_menu);
// Fix vertical offset
overflowMenuButton.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
popupMenu.show();
if (popupMenu.getDragToOpenListener() instanceof ListPopupWindow.ForwardingListener)
{
ListPopupWindow.ForwardingListener listener = (ListPopupWindow.ForwardingListener) popupMenu.getDragToOpenListener();
listener.getPopup().setVerticalOffset(-overflowMenuButton.getHeight());
listener.getPopup().show();
}
}
});

Applying gravity helped in my case
在我的情况下应用重力有帮助
PopupMenu popup = new PopupMenu(this, v, Gravity.RIGHT);

After trying out each approach that I have found, I would think putting an anchoring view might still be an easier and simpler way, especially when you are using a more flexible layout, e.g. ConstraintLayout.
在尝试了我发现的每一种方法之后，我认为放置锚定视图可能仍然是一种更容易和更简单的方法，尤其是当您使用更灵活的布局时，例如 ConstraintLayout。
Just put an invisible view to where you want the popup menu to anchor:
只需在您希望弹出菜单锚定的位置放置一个不可见的视图：
<View
android:id="@+id/anchor_menu"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginTop="10dp"
app:layout_constraintStart_toStartOf="@+id/button_menu"
app:layout_constraintTop_toBottomOf="@+id/button_menu"
/>
Then use it as the anchoring view instead:
然后将其用作锚定视图：
mPopupMenu = new PopupMenu(getActivity(), mPopupMenuAnchor);
Boom, it is done.
轰，大功告成。
回答by Sanket Kachhela
Maybe you might consider using PopupWindowinstead.
也许您可以考虑使用PopupWindow代替。
popupwindow.showAsDropDown(view,x,y);
Here xand yis position of popup window relative to your view.
这里x和y是弹出窗口相对于您的视图的位置。
