Question

我为我的英语道歉。我有个问题。我使用听众LongClick和TouchListener。

在长按中 - 视图将被删除，父视图将插入另一个父视图中。触摸停止工作，因为父改变了。

如何将TouchListener保持为View？

static boolean drag = false;
static View parent;
static OnLongClickListener olcl = new OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {

        if(!drag) {
            parent = (View) v.getParent();
            int[] loc = {0, 0};
            v.getLocationOnScreen(loc);
            ((ViewGroup) parent).removeView(v);
            Main.mainRelative.addView(v);

            RelativeLayout.LayoutParams par = (LayoutParams) v.getLayoutParams();
            par.leftMargin = loc[0];
            par.topMargin = loc[1];
            v.setLayoutParams(par);

            drag = true;
            return true;
        }
        return false;
    }
};

static OnTouchListener otl = new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {

        if(v.getParent() != null && v.getParent() == Main.mainRelative) {
            //!!!!!!!!!!!!!
            RelativeLayout.LayoutParams par = (LayoutParams) v.getLayoutParams();
            par.leftMargin = (int) (event.getRawX() - v.getWidth()/2);
            par.topMargin = (int) (event.getRawY() - v.getHeight()/1.2);
            v.setLayoutParams(par);

            for(int y = 0; y < Main.radioGroupLeftMain.getChildCount(); y++) {
                RadioButton rb = (RadioButton) ((ViewGroup) Main.radioGroupLeftMain.getChildAt(y)).getChildAt(0);
                if(checkHit((int)event.getRawX(), (int)event.getRawY(), rb)) {
                    rb.setChecked(true);
                } else {
                    rb.setChecked(false);
                }

                if(event.getAction() == MotionEvent.ACTION_UP) {


                    try { ((ViewGroup) v.getParent()).removeView(v); } catch(Exception e) {};
                    if(v.getVisibility() == View.VISIBLE) {
                        ((ViewGroup) parent).addView(v);
                    }
                    drag = false;
                }
            }   
        }



        return false;
    }
};

public static boolean checkHit(int x, int y, View v) {
    int[] loc = {0, 0};
    v.getLocationOnScreen(loc);
    Rect rv = new Rect(loc[0], loc[1], loc[0]+v.getWidth(), loc[1]+v.getHeight());


    return rv.contains(x, y);
}

当您要添加视图 Main.mainRelative.addView（v）;
时在创建新视图之前，使用此视图初始化 v ，如查看视频= v
然后再次设置触摸侦听器 vv.setOnTouchLIstener（ot1）;
试试这个应该有用......

触摸侦听器并更改父级
