我想添加一个布局片段,但我不断收到错误:如何包括布局片段的Android
Caused by: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
这是碎片如何包含在rev_lay_drawer_nav.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:id="@+id/helpAboutLL"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:id="@+id/about_bags_bttn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="About BAGS" />
<Button
android:id="@+id/help_bttn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/rev_dr_thinner_help_top"
android:text="Help" />
</LinearLayout>
</LinearLayout>
这是我怎样,我称之为:
mContext = context;
revLayDrawerLayoutInflater = LayoutInflater.from(mContext);
revLayDrawerView = revLayDrawerLayoutInflater.inflate(R.layout.rev_lay_drawer_nav, null, false);
LinearLayout helpAboutLL = (LinearLayout) revLayDrawerView.findViewById(R.id.helpAboutLL);
LinearLayout revDrawerNavViewContainer = new LinearLayout(mContext);
revDrawerNavViewContainer.setOrientation(LinearLayout.VERTICAL);
revDrawerNavViewContainer.addView(helpAboutLL);
瓦在正确的方式去呢?
错误提供了很多info.The LinearLayout中与ID helpAboutLL有已经是您的XML定义的父视图。您正尝试为其分配一个新的父级,这是错误的,因为View不能是两个View父级的子级。你可以尝试创建一个没有初始LinearLayout的xml。这种方式helpAboutLL将有一个父项。我认为它会起作用。 – Giannis
