Android工具欄覆蓋了一個片段

我在工具欄覆蓋的應用程序中有2個佈局。在我嘗試使用android:layout_below="@id/app_bar_layout或android:layout_below="@id/toolbar的每個佈局中，都沒有運氣。我怎樣才能解決這個問題？Android工具欄覆蓋了一個片段

回收者視圖通過觸摸菜單項調用，並由rv adpater和視圖持有者類充氣。到目前爲止，除了覆蓋視圖的工具欄之外，我沒有其他應用程序問題。

RVAdapter：作爲建議增加appbar_scrolling_view_behavior的

public class RVAdapter extends RecyclerView.Adapter<RVAdapter.SubjectViewHolder> { 

List<Subject> subjects; 
static SubjectViewHolder svh; 
View v = null; 
Context cxt; 

private static MyListener listener; 

public interface MyListener { 
    void onClick(View itemView, int viewPosition); 

} 


RVAdapter(List<Subject> subjects, Context cxt) { 
    this.subjects = subjects; 
    this.cxt = cxt; 
} 

public void setOnClickListener(MyListener listener) { 
    this.listener = listener; 
} 

@Override 
public void onAttachedToRecyclerView(RecyclerView recyclerView) { 
    super.onAttachedToRecyclerView(recyclerView); 
} 

@Override 
public SubjectViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) { 
    v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.cards, viewGroup, false); 
    svh = new SubjectViewHolder(v); 
    return svh; 
} 

String[] localLinks = { 
     "http://192.168.11.111:8000/pic1.png", 
     "http://192.168.11.111:8000/pic2.jpg", 
     "http://192.168.11.111:8000/pic3.png", 
     "http://192.168.11.111:8000/pic4.jpg", 
     "http://192.168.11.111:8000/pic5.png",

     "http://192.168.11.111:8000/pic8.jpg", 
     "http://192.168.11.111:8000/pic9.png", 
     "http://192.168.11.111:8000/pic10.jpg", 
     "http://192.168.11.111:8000/pic11.png",

     "http://192.168.11.111:8000/pic14.png", 
}; 


@Override 
public void onBindViewHolder(SubjectViewHolder subjectViewHolder, int i) { 
    subjectViewHolder.subjectName.setText(subjects.get(i).subjectName); 
    subjectViewHolder.subjectText.setText(subjects.get(i).subjectText); 
    Picasso.with(cxt).load(localLinks[i]).into(subjectViewHolder.subjectPhoto); 
    subjectViewHolder.expandedSubjectText.setText(subjects.get(i).expandedSubjectText); 
    subjectViewHolder.expandedSubjectText.setVisibility(View.GONE); 


} 

@Override 
public long getItemId(int position) { 
    return position; 
} 


@Override 
public int getItemCount() { 
    return subjects.size(); 
} 

public static class SubjectViewHolder extends RecyclerView.ViewHolder { 

    CardView cv; 
    TextView subjectName; 
    TextView subjectText; 
    TextView expandedSubjectText; 
    ImageView subjectPhoto; 
    Button leftButton; 
    Button rightButton; 


    SubjectViewHolder(final View itemView) { 

     super(itemView); 

     cv = (CardView) itemView.findViewById(R.id.cv); 
     subjectName = (TextView) itemView.findViewById(R.id.subject_name); 
     subjectText = (TextView) itemView.findViewById(R.id.subject_text); 
     expandedSubjectText = (TextView) itemView.findViewById(R.id.expanded_subject_text); 
     subjectPhoto = (ImageView) itemView.findViewById(R.id.subject_photo); 
     leftButton = (Button) itemView.findViewById(R.id.card_button_left); 
     rightButton = (Button) itemView.findViewById(R.id.card_button_right); 

     rightButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       if (expandedSubjectText.getVisibility() == View.GONE) { 
        expandedSubjectText.setVisibility(View.VISIBLE); 
       } else { 
        expandedSubjectText.setVisibility(View.GONE); 
       } 
       // Triggers click upwards to the adapter on click 
       if (listener != null) 
        v.findViewById(R.id.card_container); 
       listener.onClick(rightButton, svh.getAdapterPosition()); 
      } 
     }); 

     leftButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // Triggers click upwards to the adapter on click 
       if (listener != null) 
        listener.onClick(leftButton, svh.getAdapterPosition()); 
      } 
     }); 
    } 
}}

結果。一個空白欄覆蓋了剛剛動畫本身可見的文本視圖。

您必須添加以下屬性到父視圖中content_main.xml

app:layout_behavior="@string/appbar_scrolling_view_behavior"

像這樣：android:layout_height="?attr/actionBarSize" 這樣：

<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/content_frame" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.test09feb.MainActivity" 
    tools:showIn="@layout/app_bar_main" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior"> 

</FrameLayout>

謝謝。我忘了提及我已經嘗試過這種方法，但它在我的recyclerview中混淆了cardviews的佈局。每張卡都有一個「閱讀」按鈕，使文本視圖可見。添加'appbar_scrolling_view_behavior'會導致新顯示的文本視圖被屏幕底部的空白覆蓋。我會在原始響應中添加更多代碼。 – user465001

您不必爲'Card'佈局添加'app：layout_behavior'。只有'content_main.xml'文件中的父視圖 – Sharj

糟糕 - 我把它作爲一個實驗。但是，我確實在您建議的位置添加了行爲行，但仍然沒有將視圖向下推。該視圖仍然被工具欄遮蓋。 – user465001

你的工具欄高度被定義我將這些值的上邊距添加到列表視圖中： android:layout_marginTop="?attr/actionBarSize"

在我工作的應用程序中爲我工作。
