<ListView android:id="@+id/popup"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:listSelector="@android:color/transparent"/>

layout_popup_list.xml

2.java文件

private void showPopupWindow(View view) {

    // 一个自定义的布局，作为显示的内容
    View contentView = LayoutInflater.from(this).inflate(
            R.layout.layout_popup, null);

    //状态选择
    String status = "yespwd";
    ListView popuplist = (ListView)contentView.findViewById(R.id.popup);
    data = getData(status);

            R.layout.layout_popup_list, new String[] {"text"},
            new int[] {R.id.text});
    popuplist.setAdapter(simpleAdapter);
    final PopupWindow popupWindow = new PopupWindow(contentView,
            200, ViewGroup.LayoutParams.WRAP_CONTENT, true);
    //点击外部后消失
    popupWindow.setTouchable(true);
    popuplist.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            String text = (String) data.get(i).get("text");
            if (text.equals("status")) {
                Intent intent = new Intent(PrePaymentActivity.this, PaymentHistoryActivity.class);
                startActivity(intent);
　　　　　　　　　//弹框消失
　　　　　　　　　popupWindow.dismiss();
            }
        }
    });
    popupWindow.setTouchInterceptor(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return false;
            // 这里如果返回true的话，touch事件将被拦截
            // 拦截后 PopupWindow的onTouchEvent不被调用，这样点击外部区域无法dismiss
        }
    });

    // 如果不设置PopupWindow的背景，无论是点击外部区域还是Back键都无法dismiss弹框
    popupWindow.setBackgroundDrawable(getResources().getDrawable(
            R.color.white));
    // 设置好参数之后再show

    popupWindow.showAsDropDown(view);
}

//输入数据

private List<Map<String, Object>> getData(String stutas)

    }
