導航抽屜活動與我的內容重疊

-1

我打算在這個項目中使用Fragments。當我嘗試顯示片段時，工具欄會重疊到片段內容上。

我很確定這是我的XML的問題，但不知道在哪裏。 activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/drawer_layout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true" 
    tools:openDrawer="start"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

     <include 
      layout="@layout/content_main" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" /> 

    </LinearLayout> 


    <include 
     layout="@layout/app_bar_main" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

    <android.support.design.widget.NavigationView 
     android:id="@+id/nav_view" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="start" 
     android:fitsSystemWindows="true" 
     app:headerLayout="@layout/nav_header_main" 
     app:menu="@menu/activity_main_drawer" /> 

</android.support.v4.widget.DrawerLayout>

我content_main.xml包含一個空的框架佈局，使我可以添加使用的交易片段。我的片段內容出現，但頂部被工具欄隱藏。

你使用任何看法尋呼機？ –

儘量安排，使得「content_main.xml」（其中有你的片段容器）是「包括 -ed」，在「app_bar_main.xml」。

代碼：

activity_main.xml中

超級！這工作...謝謝！ –

沒問題的人！ –

包括像這樣的app_bar_main.xml內容主要：

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true" 
    tools:context="bd.tahsincom.smartsell.MainActivity" 
    tools:showIn="@layout/activity_main2"> 

    <android.support.design.widget.AppBarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:theme="@style/AppTheme.AppBarOverlay"> 

     <android.support.v7.widget.Toolbar 
      android:id="@+id/toolbar" 
      android:layout_width="match_parent" 
      android:layout_height="?attr/actionBarSize" 
      android:background="@color/colorPrimaryDark" 
      app:popupTheme="@style/AppTheme.PopupOverlay" /> 

    </android.support.design.widget.AppBarLayout> 

    <include layout="@layout/content_main" /> 

</android.support.design.widget.CoordinatorLayout>

在這裏一個新的佈局編寫代碼ü要在打開的應用程序默認的顯示設置和其能見度=「可見」！

content_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
      xmlns:app="http://schemas.android.com/apk/res-auto" 
      xmlns:tools="http://schemas.android.com/tools" 
      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" 
      app:layout_behavior="@string/appbar_scrolling_view_behavior" 
      tools:context=".MainActivity"> 

      <LinearLayout 
       android:id="@+id/strtlayID" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:orientation="vertical" 

android:visibility="visible"> 
       <ImageView 
        android:layout_width="match_parent" 
        android:layout_height="200dp" 
        android:src="@drawable/canada" 
        android:layout_marginTop="40dp"/> 
       <TextView 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_marginTop="20dp" 
        android:textSize="20dp" 
        android:textStyle="bold" 
        android:text="This is safety application for women's. "/> 
      </LinearLayout> 
      <FrameLayout 
       android:id="@+id/content_frame" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       > 

       </FrameLayout> 

     </RelativeLayout>

此處設定的佈局li.setVisibility（View.INVISIBLE）;你在哪裏得到選定片段的ID！

      @Override

      private void displaySelectedScreen(int itemId) { 
       Fragment fragment = null; 



li.setVisibility(View.INVISIBLE); 

       switch (itemId) { 
        case R.id.nav_start: 

         fragment = new start_app(); 
         pre=R.id.nav_start; 
         break;

         fragment = new Sens(); 
         break; 
       } 
       if (fragment != null) { 
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
        //ft.setCustomAnimations(R.anim.enter,R.anim.exit,R.anim.pop_enter,R.anim.pop_exit); 
        ft.replace(R.id.content_frame, fragment); 
        ft.commit(); 
       } 


       DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
       drawer.closeDrawer(GravityCompat.START); 
      } 
      @SuppressWarnings("StatementWithEmptyBody")
