我弹出的布局如下所示。为什么滚动条不出现在弹出窗口内？

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    > 

    <ScrollView 
     android:id="@+id/scroller" 
     android:layout_marginTop="16dip" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:background="@drawable/popup" 
     android:fadingEdgeLength="5dip" 
     android:scrollbars="vertical" 
     android:fillViewport="true"> 

     <LinearLayout 
      android:id="@+id/tracks" 
      android:orientation="vertical" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"

    </ScrollView > 

    <ImageView

我在弹出式窗口中显示的数据如下面的布局。

我面临的问题是，滚动条没有出现。随着弹出窗口内的数据逐渐增加，弹出窗口的大小也在增加。我想限制弹出窗口高度已经绝迹，如果弹出窗口内的数据增加，则应该出现垂直滚动视图。请找到如下屏幕截图。

请让我知道我做错了。谢谢。

数据将在列表中，我将遍历列表并将其添加到布局如下。

for (int i = 0; i < currentDateVisitsAL.size(); i++) { 
      container = mInflater.inflate(R.layout.cal_list_item_entry, mTrack,false); 
      if(flag == true) 
      { 
       pageTitle = (TextView) container.findViewById(R.id.pageTitle); 
       pageTitle.setText(day); 
       flag =false; 
      } 
      View colourBar; 
      TextView visitTimeTV; 
      TextView visitStoreNameTV; 
      TextView visitStoreAddressTV; 
      colourBar = (View) container.findViewById(R.id.vwVerticalColourBar); 
      visitTimeTV = (TextView) container.findViewById(R.id.tvVisitTime); 
      visitStoreNameTV = (TextView) container.findViewById(R.id.tvVisitStoreName); 
      visitStoreAddressTV = (TextView) container.findViewById(R.id.tvVisitStoreAddress); 


      CalendarTabView.Reminder iItem = currentDateVisitsAL.get(i); 

      int colour = mContext.getResources().getColor(R.color.white); 
      boolean isTask; 
      if (CalendarTabView.isTodo(iItem.getActivityHeader())) 
       isTask = true; 
      else isTask = false; 
      if (isTask) { 
       colour = mContext.getResources().getColor(R.color.cal_task_bg); 
      } else if (iItem.getVisitStatus().contains("I1002")) { 
       if (iItem.getActivityHeader().get__allDayVisit() != null && iItem.getActivityHeader().get__allDayVisit().equalsIgnoreCase("X")) 
        colour = Color.parseColor("#87CEFA"); 
       else 
        colour = mContext.getResources().getColor(R.color.visit_status_notstarted); 
      } else if (iItem.getVisitStatus().contains("I1003")) { 
       colour = mContext.getResources().getColor(R.color.visit_status_inprogress); 
      } else if (iItem.getVisitStatus().contains("I1005")) { 
       colour = mContext.getResources().getColor(R.color.visit_status_complete); 
      } else if (iItem.getVisitStatus().contains("I1007")) { 
       colour = mContext.getResources().getColor(R.color.native_calendar); 
      } else { 
       colour = mContext.getResources().getColor(R.color.visit_status_cancelled); 
      } 


      String fromTime = iItem.getFromTimeString(); 
      String toTime = iItem.getToTimeString(); 
      SimpleDateFormat sdf = new SimpleDateFormat("hhmm"); 
      try { 
       Date fromTimeD = iItem.getActivityHeader().getPlanStartDateTime(); 
       Date toTimeD = iItem.getActivityHeader().getPlanEndDateTime(); 
       if (DateFormat.is24HourFormat(mContext)) { 
        sdf = new SimpleDateFormat("HH:mm"); 
       } else { 
        sdf = new SimpleDateFormat("hh:mm a"); 
       } 

       fromTime = sdf.format(fromTimeD); 
       toTime = sdf.format(toTimeD); 
      } catch (Exception e) { 
       MAFLogger.e("", "", e); 
      } 

      String visitStoreName = iItem.getCustName();// Customer name 
      String visitStoreAddress; // Description 
      if (isTask) { 
       visitStoreAddress = mContext.getResources().getString(R.string.todo); 
      } else { 
       String actType = iItem.getActivityType(); 
       String actCatCode = iItem.getActivityHeader().get__ACT_CATG_CODE(); 
       visitStoreAddress = ActivityABO.getVisitTypeDescriptionByActAndCatType(actType, actCatCode); 
      } 
      colourBar.setBackgroundColor(colour); 
      visitTimeTV.setText(fromTime + "-" + toTime); 

      if (isTask && (visitStoreName == null || visitStoreName.isEmpty())) { 
       visitStoreNameTV.setText(visitStoreAddress); 
       visitStoreAddressTV.setText(""); 
      } else { 
       visitStoreNameTV.setText(visitStoreName); 
       visitStoreAddressTV.setText(visitStoreAddress); 
      } 

      mTrack.addView(container, mInsertPos); 

      mChildPos++; 
      mInsertPos++; 

      final int finalI = i; 
      container.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        if (mItemClickListener != null) { 
         mItemClickListener.onItemClick(QuickAction.this, finalI); 
        } 
       } 
      }); 

     } 
    }

mTrack是弹出式布局中线性布局的id。请找到如下代码。

public void setRootViewId(int id) { 
     mRootView = (ViewGroup) mInflater.inflate(id, null); 
     mTrack  = (ViewGroup) mRootView.findViewById(R.id.tracks); 

     mArrowDown = (ImageView) mRootView.findViewById(R.id.arrow_down); 
     mArrowUp = (ImageView) mRootView.findViewById(R.id.arrow_up); 

     mScroller = (ScrollView) mRootView.findViewById(R.id.scroller); 

     //This was previously defined on show() method, moved here to prevent force close that occured 
     //when tapping fastly on a view to show quickaction dialog. 
     //Thanx to zammbi (github.com/zammbi) 
     mRootView.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 

     setContentView(mRootView); 
    }

滚动型没有SETMAX height属性。我们需要编写自定义类。请在下面找到它。

public class MaxHeightScrollView extends ScrollView { 

    private int maxHeight; 
    private final int defaultHeight = 800; 

    public MaxHeightScrollView(Context context) { 
     super(context); 
    } 

    public MaxHeightScrollView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
     if (!isInEditMode()) { 
      init(context, attrs); 
     } 
    } 

    public MaxHeightScrollView(Context context, AttributeSet attrs, int defStyleAttr) { 
     super(context, attrs, defStyleAttr); 
     if (!isInEditMode()) { 
      init(context, attrs); 
     } 
    } 

    @TargetApi(Build.VERSION_CODES.LOLLIPOP) 
    public MaxHeightScrollView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { 
     super(context, attrs, defStyleAttr, defStyleRes); 
     if (!isInEditMode()) { 
      init(context, attrs); 
     } 
    } 

    private void init(Context context, AttributeSet attrs) { 
     if (attrs != null) { 
      TypedArray styledAttrs = context.obtainStyledAttributes(attrs, R.styleable.MaxHeightScrollView); 
      //200 is a defualt value 
      maxHeight = styledAttrs.getDimensionPixelSize(R.styleable.MaxHeightScrollView_maxHeight, defaultHeight); 

      styledAttrs.recycle(); 
     } 
    } 

    @Override 
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     heightMeasureSpec = MeasureSpec.makeMeasureSpec(maxHeight, MeasureSpec.AT_MOST); 
     super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
    } 
}

在attr.xml中添加下面的一个。

<declare-styleable name="MaxHeightScrollView"> 
    <attr name="maxHeight" format="integer" /> 
</declare-styleable>

一套固定高度pop-up'sRelativeLayout

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="300dp"> 

<ScrollView 
    android:id="@+id/scroller" 
    android:layout_marginTop="16dip" 
     android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/popup" 
    android:fadingEdgeLength="5dip" 
    android:scrollbars="vertical" 
    android:fillViewport="true"> 

    <LinearLayout 
     android:id="@+id/tracks" 
     android:orientation="vertical" 
     android:layout_width="match_parent" 
    android:layout_height="match_parent" 
     android:layout_weight="1" 
     android:padding="10dip" 
     android:gravity="top|center"/> 

</ScrollView > 

<ImageView 
    android:id="@+id/arrow_up" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:src="@drawable/arrow_up" /> 

<ImageView 
    android:id="@+id/arrow_down" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/scroller" 
    android:layout_marginTop="-4dip" 
    android:src="@drawable/arrow_down" /> 
</RelativeLayout>

谢谢你回复Kishore，它再次回复你的第二个问题。我会检查，让知道弟弟 – coders

嘿Kishore，appologies，它无法正常工作。 – coders

你的RelativeLayout和它的子'View'不合适。看看'android：orientation =“vertical”' –
