Question

我有嵌套片段，其中包含mapview，所有視圖重疊，因爲我預期除了mapview。我也有一個recyclerview ..顯示在剪切佈局下，但沒有映射。

截圖：

結果我得到的是：

，並導致我的期望：

我試圖設置性否定保證金，但它不是爲工作MapView類。

代碼： fragment_around.xml

用戶切佈局的RelativeLayout

public class CutLayout extends FrameLayout { 
    private Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); 
    private Xfermode pdMode = new PorterDuffXfermode(PorterDuff.Mode.CLEAR); 
    private Path path = new Path(); 

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

    public CutLayout(Context context, AttributeSet attrs) { 
     super(context, attrs); 
    } 

    public CutLayout(Context context, AttributeSet attrs, int defStyleAttr) { 
     super(context, attrs, defStyleAttr); 
    } 

    @TargetApi(Build.VERSION_CODES.LOLLIPOP) 
    public CutLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { 
     super(context, attrs, defStyleAttr, defStyleRes); 
    } 

    @Override 
    protected void dispatchDraw(Canvas canvas) { 
     int saveCount = canvas.saveLayer(0, 0, getWidth(), getHeight(), null, Canvas.ALL_SAVE_FLAG); 
     super.dispatchDraw(canvas); 

     paint.setXfermode(pdMode); 
     path.reset(); 

     path.moveTo(0, getHeight()); 
     path.lineTo(getWidth(), getHeight()); 
     path.lineTo(getWidth(), getHeight() - TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 60, getResources().getDisplayMetrics())); 
     path.close(); 
     canvas.drawPath(path, paint); 

     canvas.restoreToCount(saveCount); 
     paint.setXfermode(null); 
    } } 

代替和在XML文件

<com.helper.CutLayout 
     android:id="@+id/background" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <ImageView 
      android:scaleType="fitXY" 
      android:src="@drawable/aroundme" 
      android:layout_width="match_parent" 
      android:layout_height="230dp" /> 
</com.helper.CutLayout>
