禁用和啓用視圖機器人

我的目標是繪製上述谷歌地圖v2的自由形狀，所以我創建一個應用程序來繪製由手指移動自由的形狀在定製視圖和layout.xml推杆地圖片段高於此視圖和使視圖背景變得透明。現在我可以很好地繪製自由形狀，但現在的問題是我無法控制地圖或縮放或拖動它。禁用和啓用視圖機器人

是否有什麼辦法可以讓我控制他們兩個，例如按鈕隱蔽從地圖片段面圖的控制，反之亦然？或打開/關閉繪圖視圖？

這是我的代碼

DrawerView.java

public class DrawerView extends View { 

public Paint paint = new Paint(); 
public Path path = new Path(); 
public Path circlePath = new Path(); 

private int lineCol; 


public LayoutParams params; 


public DrawerView(Context context, AttributeSet attrs){ 
    super(context, attrs); 

    //get the attributes specified in attrs.xml using the name we included 
    TypedArray a = context.getTheme().obtainStyledAttributes(attrs, 
      R.styleable.LineView, 0, 0); 

    try { 
     //get the text and colors specified using the names in attrs.xml 

     lineCol = a.getInteger(R.styleable.LineView_lineColor, 0);//0 is default 

    } finally { 
     a.recycle(); 
    } 

    //paint object for drawing in onDraw 
    paint.setAntiAlias(true); 
    paint.setColor(lineCol); 
    paint.setStyle(Paint.Style.STROKE); 
    paint.setStrokeJoin(Paint.Join.ROUND); 
    paint.setStrokeWidth(4f); 

}

    // resets the screen 
    path.reset();

    postInvalidate();

    canvas.drawPath(path, paint); 
    //canvas.drawPath(circlePath, circlePaint); 
}

    // Gives you x and y coordinates on the Event. 
    float pointX = event.getX();

    switch (event.getAction()) { 
    case MotionEvent.ACTION_DOWN: 
     path.moveTo(pointX, pointY); 

     return true; 
    case MotionEvent.ACTION_MOVE: 
     path.lineTo(pointX, pointY); 
     circlePath.reset(); 

     circlePath.addCircle(pointX, pointY, 30, Path.Direction.CW); 
     break; 

    case MotionEvent.ACTION_UP: 
     circlePath.reset(); 

     break; 
    default: 
     return false;

是的，你可以的接收器之間切換通過在onTouchEvent返回false觸摸事件，這應該傳播事件到下一個視圖。

UPD：代碼應該是這樣的：

@Override 
public boolean onTouchEvent(MotionEvent event) { 
if (!isTouchable) return false; 
// your DrawerView logic 
}

其中isTouchable是一個布爾變量應該是false是你不想動用你的看法和true如果你想畫。

你能告訴我怎麼用代碼？這會讓我再次控制地圖嗎？ – Eman87

是的，這應該返回您在地圖 – Desert

的控制非常感謝你的幫助，它現在與我。 :) – Eman87

您可以啓用或禁用點擊繪圖覆蓋：

findViewById(R.id.custView).setClickable(true/false);

雖然您的繪圖覆蓋無法點擊，您就可以與地圖交互。
