Android 将弹出菜单设置为全屏

注意：这是弹出式菜单，不是弹出式窗口。所以请大家仔细阅读

我已经实现了弹出菜单。它显示在屏幕的一半。我想把它扩展到整个设备的宽度。我试图通过将

layout\u width

设置为

match\u parent

来改变它的样式，但没有成功

以下是我迄今为止所做的尝试：

风格

 <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->

        <item name="popupMenuStyle">@style/PopupMenu</item>
    </style>

  <!-- Change Overflow Menu Background -->
    <style name="PopupMenu" parent="android:Widget.Holo.Light.ListPopupWindow">
        <item name="android:popupBackground">#888888</item>
        <item name="android:layout_width">match_parent</item>
    </style>

@样式/弹出菜单
#888888
匹配父项

下面是我的java代码：

  PopupMenu menu = new PopupMenu(getActivity(), tvnext);


    for (int i = 0; i < array.size(); i++) {

        menu.getMenu().add(1, i, 1, array.get(i).getAccountName());

    }


    menu.show();

    menu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem item) {
            setUpNextFunctionality(item.getItemId());


            return false;
        }
    });

PopupMenu=new PopupMenu（getActivity（），tvnext）；
对于（int i=0；i

请不要建议我使用弹出窗口。如果不起作用，这是我的最后一个选择。

尝试以下操作：

pwindow = 
    new PopupWindow(layoutt,LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,true);

试试这个

充气机。充气（右布局。菜单，菜单）

或

菜单。充气（右布局。弹出菜单）

如果不实现类似于

PopupMenu

的弹出窗口，我认为您无法做到这一点。如果要选中菜单OpupHelper:：createPopup：

@NonNull
private MenuPopup createPopup() {
    final WindowManager windowManager = (WindowManager) mContext.getSystemService(
            Context.WINDOW_SERVICE);
    final Display display = windowManager.getDefaultDisplay();
    final Point displaySize = new Point();

    if (Build.VERSION.SDK_INT >= 17) {
        display.getRealSize(displaySize);
    } else if (Build.VERSION.SDK_INT >= 13) {
        display.getSize(displaySize);
    } else {
        displaySize.set(display.getWidth(), display.getHeight());
    }

    final int smallestWidth = Math.min(displaySize.x, displaySize.y);
    final int minSmallestWidthCascading = mContext.getResources().getDimensionPixelSize(
            R.dimen.abc_cascading_menus_min_smallest_width);
    final boolean enableCascadingSubmenus = smallestWidth >= minSmallestWidthCascading;

    final MenuPopup popup;
    if (enableCascadingSubmenus) {
        popup = new CascadingMenuPopup(mContext, mAnchorView, mPopupStyleAttr,
                mPopupStyleRes, mOverflowOnly);
    } else {
        popup = new StandardMenuPopup(mContext, mMenu, mAnchorView, mPopupStyleAttr,
                mPopupStyleRes, mOverflowOnly);
    }

    // Assign immutable properties.
    popup.addMenu(mMenu);
    popup.setOnDismissListener(mInternalOnDismissListener);

    // Assign mutable properties. These may be reassigned later.
    popup.setAnchorView(mAnchorView);
    popup.setCallback(mPresenterCallback);
    popup.setForceShowIcon(mForceShowIcon);
    popup.setGravity(mDropDownGravity);

    return popup;
}

您将看到弹出菜单的大小是根据显示大小硬编码的。所以，最简单的方法可能是检查

PopupMenu

相关的源代码并实现类似的功能，但大小要符合您的需要。

尝试在您的样式中设置minWidth，如下所示

     <item name="android:minWidth">1000dp</item>

1000dp

我知道你的问题了。不要修改某些东西，而是使用新的小部件，它可以轻松满足您的需要，并与新版本兼容

要在android中使用它，您可以使用git hub库，如

使其半透明。我做了同样的弹出像这样。请检查一下这个。也许它对你也有用。
