Android的替代片段仍然显示了一些取代片段 [英] Android replace fragment still displays some of the replaced fragment

问题描述

我有一个包含一个搜索查看和列表视图线性布局的标签。当用户点击的搜索结果中的一个，我希望替换布局与含有选择的细节的另一布局。

I have a tab that contains a linear layout with a searchview and a listview. When the user clicks one of the search results, I want to replace that layout with another layout containing the details of the selection.

在我替换搜索片段的布局只有列表视图部分被替换会发生什么事;在搜索查看仍然可见，活跃在荧屏上。

What happens when I replace the search fragment only the listview portion of the layout gets replaced; the searchview is still visible and active on the screen.

下面是我的搜索布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/search_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <SearchView
        android:id="@+id/public_calendar_search"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:iconifiedByDefault="false"
    </SearchView>

    <ListView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1.0"
        android:choiceMode="singleChoice" />

    <TextView
        android:id="@android:id/empty"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:gravity="center"/>

</LinearLayout>

下面是详细的布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/detail_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:baselineAligned="false"
        android:orientation="vertical" >

        <Space
            android:layout_width="0dip"
            android:layout_height="20dip"
            android:layout_weight="1" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:baselineAligned="false"
        android:orientation="horizontal" >

        <Space
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight=".1" />

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight=".8"
            android:text="@string/label_Name" />

        <Space
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight=".1" />
    </LinearLayout>

    .........

</LinearLayout>

和我的code来代替搜索片段：

And my code to replace the search fragment:

FragmentTransaction transaction = getFragmentManager().beginTransaction();

// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack.
DetailFragment fragment = DetailFragment.newInstance(cal);
transaction.replace(R.id.search_layout, fragment);

transaction.addToBackStack(null);
transaction.commit();

详细片断创建：

Detail fragment creation:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.detail_layout, container, false);
    return v;
}

static DetailFragment newInstance(String cal) {
    DetailFragment d = new DetailFragment();
    return d;
}

我是什么做错了吗？我怎样才能得到整个搜索布局进行更换。

What am I doing wrong? How can I get the entire search layout to be replaced.

谢谢！

推荐答案

我想通了，我的问题。马是不完全正确的，但他指出我朝着正确的方向发展。

I figured out my problem. Marco wasn't exactly right but he pointed me in the right direction.

的问题是该容器ID我被传递给替换方法的片段我被替换，而不是片段容器的ID的ID。这似乎可以解释为什么一些原本片段控制人后剩余取代 - 这整个片段不被替换

The problem was the the container ID I was passing to the replace method was the ID of the fragment I was replacing, not the ID of the fragment container. This seems to explain why some of the original fragment controls were remaining after the replace - that entire fragment wasn't being replaced.

我把它拿到片段容器视图的ID，而且成功了！这里的code：

I changed it to get the fragment container view ID, and that worked! Here's the code:

transaction.replace(((ViewGroup)(getView().getParent())).getId(), fragment); 

我找到了答案获取一个片段的容器视图ID在这里，获取片段的容器视图ID 。
