Question

当我尝试将自定义视图添加到ScrollView的子（RelativeLayout）时，我遇到了ScrollView的问题。 删除scrollView时，它可以正常工作。

这是xml文件

    <ScrollView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:clickable="true"
        android:id="@+id/scrollView">


    <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_below="@+id/relativeLayout"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_alignRight="@+id/relativeLayout"
            android:layout_alignEnd="@+id/relativeLayout"
            android:id="@+id/rlSelectable">
        <View android:layout_width="match_parent"
              android:layout_height="120dp"

              android:layout_alignParentStart="true"/>
    </RelativeLayout>

</ScrollView>

注意：ScrollView在xml布局中不是父级。它包含在RelativeLayout中。

这是MainActivity代码：

public class MainActivity extends AppCompatActivity implements Dragger.DraggerInterface {

GestureDetector detector;
ArrayList<Dragger> draggers;
RelativeLayout rlSelectable;
int width,height,count=0,startsAt=0;
float centerX;
ScrollView scrollView;
String TAG = "MAIN_DRAGGER";

View view;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.calendar_view);

    view = findViewById(R.id.view1);
    rlSelectable = (RelativeLayout) findViewById(R.id.rlSelectable);
    draggers = new ArrayList<Dragger>();
    scrollView = (ScrollView)findViewById(R.id.scrollView);
    scrollView.requestDisallowInterceptTouchEvent(true);
    detector = new GestureDetector(new GestureDetector.SimpleOnGestureListener(){
        @Override
        public boolean onDown(MotionEvent e) {
            return true;
        }

        @Override
        public boolean onSingleTapConfirmed(MotionEvent e) {
            int index  = MotionEventCompat.getActionIndex(e);
            float x = MotionEventCompat.getX(e, index);
            float y = MotionEventCompat.getY(e, index);
            addDragger(centerX,y);
            log("single tapped");
            return true;
        }
    });




    rlSelectable.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return detector.onTouchEvent(event);
        }
    });
}


@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    width = rlSelectable.getWidth();
    centerX = (rlSelectable.getRight()-rlSelectable.getLeft())/2;
    height = view.getHeight();
    startsAt = view.getTop();
}


public void addDragger(float x,float y) {
    Dragger dragger = new Dragger(MainActivity.this);
    dragger.setParams(width,height);
    dragger.setCenter(x, y);
    draggers.add(dragger);
    dragger.setId(count++);
    dragger.viewStartsAt(startsAt);
    dragger.addView(this);
    rlSelectable.addView(dragger);

}




private void log(String message){
    Log.d(TAG,message);
}

@Override
public void checkBounds(Dragger current) {
    int currentId = current.getId();

    if(draggers.size()>1){
        for(Dragger dragger : draggers){

            if(currentId !=dragger.getId()){
                if(current.getUpState() && current.getRectTop()<dragger.getRectBootom() && current.getRectBootom() > dragger.getRectTop()){
                    dragger.setBottom(current.getRectBootom());
                    current.removeView();
                    draggers.remove(current);
                    break;
                }else if(!current.getUpState() && current.getRectBootom() > dragger.getRectTop() && current.getRectTop() < dragger.getRectBootom()){
                    dragger.setTop(current.getRectTop());
                    current.removeView();
                    draggers.remove(current);
                    break;
                }
            }
        }
    }
}
