我有一個應用程序,我想在recyclerview中顯示服務器的dataList,當我滾動到recyclerView結束時,想要顯示底部的進度條,並且我還在recyclerview之間添加了AdsView,但它與recyclerView的項目重疊指定的索引。顯示視圖時,它與recyclerview中的項目重疊?

代碼: -

@Override 
public int getItemViewType(int position) { 
    if (contacts.get(position) == null) 
     return VIEW_TYPE_LOADING; 
    else if (position % 5 == 0) 
     return AD_VIEW; 
    else { 
     return VIEW_TYPE_ITEM; 
    } 
} 

@Override 
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view = null; 
    if (viewType == AD_VIEW) { 
     View adView = LayoutInflater.from(parent.getContext()).inflate(R.layout.add, parent, false); 
     return new AdView(adView); 
    } else if (viewType == VIEW_TYPE_ITEM) { 
     view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_recycler_view_row, parent, false); 
     return new UserViewHolder(view); 
    } else if (viewType == VIEW_TYPE_LOADING) { 
     view = LayoutInflater.from(activity).inflate(R.layout.item_loading, parent, false); 
     return new LoadingViewHolder(view); 
    } 
    return null; 
} 

@Override 
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 
    if (holder instanceof AdView) { 
     AdView adView = (AdView) holder; 
     adView.textView.setText("Ads"); 
    } else if (holder instanceof UserViewHolder) { 
     Contact contact = contacts.get(position); 
     UserViewHolder userViewHolder = (UserViewHolder) holder; 
     userViewHolder.phone.setText(contact.getEmail()); 
     userViewHolder.email.setText(contact.getPhone()); 
    } else if (holder instanceof LoadingViewHolder) { 
     LoadingViewHolder loadingViewHolder = (LoadingViewHolder) holder; 
     loadingViewHolder.progressBar.setIndeterminate(true); 
    } 
} 

@Override 
public int getItemCount() { 
    return contacts == null ? 0 : contacts.size(); 
} 

XML主

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin"> 

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

ItemView控件

<android.support.v7.widget.CardView 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:card_view="http://schemas.android.com/apk/res-auto" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
card_view:cardUseCompatPadding="true"> 

<RelativeLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="?android:selectableItemBackground" 
    android:padding="10dp"> 

    <TextView 
     android:id="@+id/txt_email" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:textColor="@android:color/black" 
     android:textSize="16sp" 
     android:textStyle="bold" /> 

    <TextView 
     android:id="@+id/txt_phone" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_below="@id/txt_email" 
     android:textColor="@android:color/black" 
     android:textSize="12sp" /> 
</RelativeLayout> 

的XML

XML loadingview的: - 需要爲了讓我們理解元素是如何排序,並視對方

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

<ProgressBar 
    android:id="@+id/progressBar1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center_horizontal" />

請發佈您用於此目的的XML(Progressbar,recyclerview) –

爲什麼需要xml – Raghav

我的問題是隻有當額外的視圖名爲「AD_VIEW」時,它與指定索引處的recyclerview項重疊時才被命名爲「AD_VIEW」。 .. – Raghav

你的XML。 但是,在您發佈它之前,您可以將您的recyclerView放置在RelativeLayout中,並將其設置爲低於(或高於)其重疊視圖。 但是請注意,兩個視圖(回收站和重疊視圖或回收站的佈局以及重疊視圖)應該位於相同的RelativeLayout下,以便它們可以具有位置依賴性。
