Question

使用RecyclerView的导航抽屉碎片不适用于除Lollipop设备之外的任何设备，请帮助

NavigationDrawerFragment.java

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    mRecyclerView = (RecyclerView) view.findViewById(R.id.rv_drawer_menu);
    mAdapter = new NavigationAdapter(getActivity(), getItems());
    mRecyclerView.setAdapter(mAdapter);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

}

在除Lollipop之外的所有设备上给出例外。删除行setLayoutManager会使错误消失但然后RecyclerView无法正常工作

我的build.gradle

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.+'
compile 'com.android.support:recyclerview-v7:+'
compile 'com.android.support:support-v4:+'

}

布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="@dimen/navigation_drawer_width"
    android:layout_height="match_parent"
    android:background="@color/backgrounds"
    tools:context="com.xx.xx.supporting.NavigationDrawerFragment">

    <RelativeLayout
        android:id="@+id/rl_pic"
        android:layout_width="@dimen/navigation_drawer_width"
        android:layout_height="wrap_content"
        android:background="@color/backgrounds">

        <ImageView
            android:layout_width="@dimen/navigation_drawer_width"
            android:layout_height="130dp"
            android:layout_marginBottom="@dimen/margin_full"
            android:src="@drawable/img_abstract" />

    </RelativeLayout>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_drawer_menu"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/rl_pic">

    </android.support.v7.widget.RecyclerView>

</RelativeLayout>

Answer 1

您是否设置了RecyclerView的方向？

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
   mRecyclerView = (RecyclerView) view.findViewById(R.id.rv_drawer_menu);
   LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
   linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
   mRecyclerView.setLayoutManager(linearLayoutManager);
   mAdapter = new NavigationAdapter(getActivity(), getItems());
   mRecyclerView.setAdapter(mAdapter);
}

Answer 2

您是否检查过libs文件夹中的android-support-v7-recyclerview.jar库？如果是，那么检查您的清单文件是否具有目标sdk版本 21

  <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="21" />

因为在互联网上尝试了所有内容后，我通过将目标从 17 更改为 21 来解决了recyclelerview膨胀错误。

可能这对未来的某些人有帮助，而不是像我一样浪费时间。

使用RecyclerView的NavigationDrawerFragment不起作用
