顏色問題（Android）

Question

我正在升級我的應用以包含操作欄，我對格式有點困惑。

所以第一個活動看起來不錯，這裏是代碼：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

<TextView 
    android:id="@+id/main_title" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/main_title" 
    android:textSize="24sp" 
    android:textColor="@color/orange" 
    android:textStyle="bold" 
    android:gravity="center_vertical|center_horizontal" 
    android:padding="20dp"/> 
    <Button 
    android:id="@+id/new_inspection" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/main_title" 
    android:text="@string/create_new_inspection"/> 
    <TextView 
    android:id="@+id/saved_inspections" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/new_inspection" 
    android:text="@string/saved_inspections" 
    android:padding="5dp"/> 
    <ListView 
    android:id="@id/android:list" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/saved_inspections"/> 
    <TextView 
    android:id="@id/android:empty" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/no_saved_inspections" 
    android:gravity="center" 
    android:padding="20dp" 
    android:layout_below="@id/saved_inspections"/> 
</RelativeLayout> 

的onCreate方法本：

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_inspection); 
    setUpViews(); 
    setLongClick(); 
    rmDbHelper = new RMDbAdapter(this); 
    rmDbHelper.open(); 
    Cursor listCursor = rmDbHelper.fetchAllInspections(); 
    startManagingCursor(listCursor);   
    setListAdapter(new MyListAdapter(this, listCursor)); 
} 

，看起來像這樣：

但其他一些活動不是這樣，我不知道爲什麼 - 例如，這裏是下一個活動代碼：它看起來像這樣

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_run); 
    rmDbHelper = new RMDbAdapter(this); 
    rmDbHelper.open(); 
    Intent i = getIntent(); 
    inspectionId = i.getLongExtra("Intent_InspectionID", -1); 
    areaId = i.getLongExtra("Intent_AreaID", -1); 
    setUpViews(); 
    setLongClick(); 
    Cursor listCursor = rmDbHelper.fetchAllRunsForArea(areaId); 
    startManagingCursor(listCursor);   
    setListAdapter(new MyListAdapter(this, listCursor)); 
} 

：

的OnCreate此

的顏色是遍佈該店和我看不到在xml文件中有所不同..

下面是信息清單：

Answer 1

只需設置父佈局的背景顏色以黑色爲：

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    android:background="@android:color/black"> 

，或者設置應用主題：

Theme.Black.NoTitleBar 

比希望它看起來很好。
