配置好的popupwindow 拿来就用

private void showPopupWindow(View view) { // 一个自定义的布局，作为显示的内容 View contentView = LayoutInflater.from(ValidationRunmanActivtiy.this).inflate(R.layout.pop_xieyi_read, null); // 设置按钮的点击事件 TextView button = (TextView) contentView.findViewById(R.id.bt_read); WebView webView = (WebView) contentView.findViewById(R.id.wb_content); webView.setWebViewClient (new MyWebViewClient ()); String url = ServerConfig.getServer ().API_HOST + getResources ().getString (R.string.agreementHtmlUrl); webView.loadUrl (url); final PopupWindow popupWindow = new PopupWindow(contentView,CommonUtils.dip2px(appContext, 320), CommonUtils.dip2px(appContext, 520), true); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if(null != popupWindow && popupWindow.isShowing()) { popupWindow.dismiss(); } } }); popupWindow.setTouchable(true); // 点击外围会隐藏 popupWindow.setOutsideTouchable(false); // 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.drawable.list_item_cover_center)); // 设置好参数之后再show popupWindow.showAtLocation(ll_llll, Gravity.CENTER , 0 , 0 ); }
