Android 替换片段仍然显示一些被替换的片段 [英] Android replace fragment still displays some of the replaced fragment

问题描述

我有一个包含带有搜索视图和列表视图的线性布局的选项卡.当用户点击其中一个搜索结果时，我想用另一个包含选择细节的布局替换该布局.

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.

当我替换搜索片段时会发生什么，只有布局的列表视图部分被替换；搜索视图在屏幕上仍然可见并处于活动状态.

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.

这是我的搜索布局:

<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>

这里是详细布局:

<?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>

还有我替换搜索片段的代码:

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();

细节片段创建:

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;
}

我做错了什么?如何让整个搜索布局被替换.

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

谢谢！

推荐答案

我发现了我的问题.马可并不完全正确，但他为我指明了正确的方向.

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

问题是我传递给 replace 方法的容器 ID 是我正在替换的片段的 ID，而不是片段容器的 ID.这似乎解释了为什么一些原始片段控件在替换后仍然保留 - 整个片段没有被替换.

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.

我将其更改为获取片段容器视图 ID，并且奏效了！代码如下:

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

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

我在这里找到了获取片段的容器视图 ID 的答案，获取片段的容器视图id.

I found the answer for getting the container view ID of a fragment here, Get fragment's container view id.
