PopupWindow 点击按钮的泡泡

PopupWindow 属性用来设置视图的位置

主java写

package com.example.popupwindow;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        
        
    }
    public void dian(View v){//点击事件
        View view = View.inflate(this, R.layout.popup_window, null);
        GridView viewById = (GridView) view.findViewById(R.id.gv);
        viewById.setAdapter(new MyActivity());//设置九宫格
        //设置冒泡
        pw=new PopupWindow(view,
                ViewGroup.LayoutParams.MATCH_PARENT,//填充宽度
                ViewGroup.LayoutParams.WRAP_CONTENT);//包裹内容填充(内容是View的match填充父窗体,填充父窗体就是包裹内容,包裹内容-->View的填充父窗体--->(两个结合父类的wrap_..)--->GridView的包裹内容)
        pw.setBackgroundDrawable(new BitmapDrawable());//可绘制的位图
        pw.setFocusable(true);//设置可聚焦的 //显示/消失
//      pw.showAsDropDown(v);//指定在控件上的按钮的下方出现
        //显示在屏幕下方   (v是按钮v.getparent()是父布局,显示在什么位置,x水平的偏移量,y是垂直的偏移量)
        pw.showAtLocation((View) v.getParent(), Gravity.BOTTOM, 0, 0);
    
    }

显示在右下

int[] location = new int[2];
                view.getLocationOnScreen(location);
                mPw.showAtLocation(view, Gravity.NO_GRAVITY, location[0]+view.getWidth(), location[1]+view.getHeight());

显示在右下也可以用包含自带的点击效果(动画)

 // 通过WindowManager获取
        mDm = new DisplayMetrics();
        getActivity().getWindowManager().getDefaultDisplay().getMetrics(mDm);
//                System.out.println("width-display :" + dm.widthPixels);
//                System.out.println("heigth-display :" + dm.heightPixels);
        //设置冒泡
        mPw = new PopupWindow(view,
                ViewGroup.LayoutParams.WRAP_CONTENT,//填充宽度
                ViewGroup.LayoutParams.WRAP_CONTENT);//包裹内容填充(内容是View的match填充父窗体,填充父窗体就是包裹内容,包裹内容-->View的填充父窗体--->(两个结合父类的wrap_..)--->GridView的包裹内容)
        mPw.setBackgroundDrawable(new BitmapDrawable());//可绘制的位图
        mPw.setFocusable(true);//设置可聚焦的 //显示/消失
        lv.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView adapterView, View view, int i, long l) {
                mContent = list.get(i-1).get("content");//一共有几条
                delete=i-1;//从集合中删除

                mPw.showAsDropDown(view, mDm.widthPixels,0);//他不会把自己挤没
