从膨胀的布局中删除黑色边框 [英] remove black border from inflated layout
问题描述
我正在使用PopupWindow
,它工作正常,但是问题是在放大显示有黑色边框的布局视图之后.
I am using PopupWindow
, which is working fine, but the problem is after inflating the layout view that is shown with black border.
final PopupWindow popupWindow = new PopupWindow(context);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.pop_up_window_menu_layout, null);
popupWindow.setContentView(view);
pop_up_window_menu_layout.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/solid_white"
android:orientation="vertical" >
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:gravity="center_vertical"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:text="SAVE"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:textColor="@color/black"
android:textSize="@dimen/txt_size_sliding_list" />
我尝试使用popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT))
删除边框,但是问题仍然相同.
I've tried to remove border by using popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT))
, but problem is still same.
有人可以告诉我如何删除不需要的黑色边框吗?
Can anyone tell me how to remove unwanted black border?
推荐答案
我的弹出窗口周围没有看到任何边框,但是我将它们设置为与您稍有不同.希望这会为您指明正确的方向.
I don't see any border around my popup windows, but I do set them up slightly different than you. Hopefully this points you in the right direction.
