触摸 android.gesture.GestureOverlayView 时在 ScrollView 中阻止滚动

Question

我尝试在 ScrollView 中实现 android.gesture.GestureOverlayView。在我的 activity.xml

<?xml version="1.0" encoding="utf-8"?>
   <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:id="@+id/scrollViewreceipt"
   >
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical" android:layout_width="match_parent"
   android:layout_height="match_parent">
       <include
       android:id="@+id/include1"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       layout="@layout/toolbar" />
      <Spinner
        android:id="@+id/custom_spinner"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:theme="@android:style/Theme.Holo.Light.DarkActionBar"/>

      <ListView
        android:id="@+id/customList"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:layout_marginTop="15dp" />

      <android.gesture.GestureOverlayView
           android:id="@+id/signaturePad"
            android:layout_width="match_parent"
            android:layout_height="80dp"
            android:layout_weight="5"
            android:background="#d3d3d3"
            android:eventsInterceptionEnabled="true"
            android:fadeEnabled="false"
            android:gestureColor="#333"
            android:gestureStrokeLengthThreshold="0.1"
            android:gestureStrokeType="multiple"
            android:fadeOffset="5000"
            android:orientation="vertical" >
        </android.gesture.GestureOverlayView>

       <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:onClick="testImage"
            android:text="test"/>
</LinearLayout>

但是当我尝试在我的 android.gesture.GestureOverlayView 上绘制视图滚动时，它无法使用，所以我问我如何在触摸 android.gesture.GestureOverlayView 时阻止滚动。

我是这样解决的：

我用 CustomScrollView

扩展了一个 ScrollView

public class CustomScrollView extends ScrollView {
 private boolean enableScrolling = true;

public boolean isEnableScrolling() {
    return enableScrolling;
}

public void setEnableScrolling(boolean enableScrolling) {
    this.enableScrolling = enableScrolling;
}

public CustomScrollView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

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

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

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {

    if (isEnableScrolling()) {
        return super.onInterceptTouchEvent(ev);
    } else {
        return false;
    }
}
@Override
public boolean onTouchEvent(MotionEvent ev) {
    if (isEnableScrolling()) {
        return super.onTouchEvent(ev);
    } else {
        return false;
    }
}
}

在我的 XML 中，我用我的新扩展 class 和 id

更改了 ScrollView

<com.itmind.spac.spacapp.custom_extends.CustomScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/scrollViewreceipt"
>......</com.itmind.spac.spacapp.custom_extends.CustomScrollView>

并且在我的 ActivityClass

public class CustomActivity  implements GestureOverlayView.OnGestureListener {
CustomScrollView myScrollView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState, R.layout.activity_receipts);

    GestureOverlayView signaturePad = (GestureOverlayView) findViewById(R.id.signaturePad);
    myScrollView = (CustomScrollView) findViewById(R.id.scrollViewreceipt);
    assert myScrollView != null;


    assert signaturePad != null;
    signaturePad.addOnGestureListener(this);
}
@Override
public void onGestureStarted(GestureOverlayView overlay, MotionEvent event) {
    myScrollView.setEnableScrolling(false);
}

@Override
public void onGesture(GestureOverlayView overlay, MotionEvent event) {
}

@Override
public void onGestureEnded(GestureOverlayView overlay, MotionEvent event) {
    myScrollView.setEnableScrolling(true);
}

@Override
public void onGestureCancelled(GestureOverlayView overlay, MotionEvent event) {
}
