方法：

    public void showpopupwindow() {
        LayoutInflater inflater = LayoutInflater.from(PersonalInfoActivity.this);
        View v = inflater.inflate(R.layout.item_add, null);
        Button album = (Button) v.findViewById(R.id.album);
        Button camera = (Button) v.findViewById(R.id.camera);
        Button cancel = (Button) v.findViewById(R.id.cancel);
        album.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                // 相册选择图片
                //setalbumImg();
             }
        });
        camera.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
            //    setcameraImg(type2);
            }
        });
        cancel.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                pw.dismiss();
            }
        });
        // 一般来说，我们在onCreate里面得到的控件的宽高全是０.采用下面的方法，可以得到真实的宽高
        int w = View.MeasureSpec.makeMeasureSpec(0,
                View.MeasureSpec.UNSPECIFIED);
        int h = View.MeasureSpec.makeMeasureSpec(0,
                View.MeasureSpec.UNSPECIFIED);
        v.measure(w, h);
        int v_h = v.getMeasuredHeight();
        int v_w = v.getMeasuredWidth();

        pw = new PopupWindow(v, LayoutParams.MATCH_PARENT, v_h);
        pw.setFocusable(true);
    }

使用：

private PopupWindow pw;

showpopupwindow();
pw.showAtLocation(findViewById(R.id.m), Gravity.BOTTOM, 0, 0);//m是整个当前的根布局id
