訪問自定義視圖中的標準佈局屬性

Question

我想從傳遞給我的自定義視圖的構造函數的標準屬性中拉出寬度規格和高度規範，以便我可以調整它們並作爲新的佈局窗體返回，以便當我要顯示視圖在活動鎖中旋轉爲縱向。

我無法找到intarray中需要傳遞的靜態int值來獲取這些原始值。他們在哪？

public static final int[] stdatts = {valForandroid:layout_width,...height,...gravity}; 
TypedArray natts = getContext().getResources().obtainAttributes(attrs, stdatts); 
int widset = natts.getInteger(valForandroid:layout_width, 0); 
int hitset = ....; 
int gravset = .....; 
if (orientIsV) 
    FrameLayout.LayoutParams reset = new FrameLayout.LayoutParams (widset, hitset, gravset); 
else 
    FrameLayout.LayoutParams reset = new FrameLayout.LayoutParams (hitset, widset, gravset); 

我可以通過查看屬性陣列我居然獲得通過，在發現這些容易足夠的價值，但這顯然是一個非常骯髒的和不可靠的修復

不太答案我希望 - 我給試圖以這種方式處理這個問題 - 數據格式非常難以理解。這裏是旋轉的擴展relativelayout類的代碼的一部分，保持其中的所有內容不變，它也保持左/右對齊正確並正確處理觸摸事件。例如，它將允許嵌套的Seekbar處於任何方向，避免需要特殊情況下的seekbar。

public void setOrientation() { 
    if (rSource == RotateSetBy.globalStatic) { 
    currRotate = PootleViewExtras.deviceOrient; 
    } 
    boolean isVert = currRotate == Orientations.up || currRotate == Orientations.down; 
    if (lockSize > 0 && widthAtt < 0 && heightAtt < 0) { 
    int lws = 0; 
    int lhs = 0; 
    if (isVert) { 
     lws = widthAtt; 
     lhs = heightAtt; 
    } else { 
     lhs = widthAtt; 
     lws = heightAtt; 
    } 
    int setgrav = gravityAtt & 0x11; // messy but seems to do the right things 
    if (currRotate == Orientations.down) { 
     if ((gravityAtt & 0x2) != 0) setgrav |= 0x4; 
     if ((gravityAtt & 0x4) != 0) setgrav |= 0x2; 
     if ((gravityAtt & 0x20) != 0) setgrav |= 0x40; 
     if ((gravityAtt & 0x40) != 0) setgrav |= 0x20; 
    } else { 
     setgrav = gravityAtt; 
    } 

    FrameLayout.LayoutParams reset = new FrameLayout.LayoutParams (lws, lhs, setgrav); 
    this.setLayoutParams(reset); 
    } 
}

} 

@Override

    if (currRotate == Orientations.up) {

    canvas.save(); 
    canvas.concat(mForward); 
    super.dispatchDraw(canvas); 
    canvas.restore(); 
    } 
} 

@Override 
public boolean dispatchTouchEvent(MotionEvent event) {

//  return super.dispatchTouchEvent(event); 
// } else { 
    final float[] temp = mTemp; 
    temp[0] = event.getX(); 
    temp[1] = event.getY(); 

    mReverse.mapPoints(temp); 
    event.setLocation(temp[0], temp[1]); 
    return super.dispatchTouchEvent(event);
