跳转支付宝扫描二维码，付款码，收款码，和手机计算器，日历

主要再次做一下记录，防止以后又重新找一边。

主要是支付宝跳转:

         //微信
                //weixin://dl/scan 扫一扫
                // "weixin://dl/moments"朋友圈
//                String intentFullUrl ="alipayqr://platformapi/startapp?saId=10000007";//支付宝扫码的uri
//                String intentFullUrl ="alipayqr://platformapi/startapp?saId=20000056";//支付宝付款吗码的uri
                String intentFullUrl ="alipays://platformapi/startapp?appId=20000123";//支付宝收款码的uri
                Intent intent = null;try {intent = Intent.parseUri(intentFullUrl, Intent.URI_INTENT_SCHEME );startActivity(intent);} catch (URISyntaxException e) {e.printStackTrace();}

/**
 * 判断支付宝是否安装
 * @param context
 * @return
 */
public static boolean checkAliPayInstalled(Context context) {Uri uri = Uri.parse("alipays://platformapi/startApp");Intent intent = new Intent(Intent.ACTION_VIEW, uri);ComponentName componentName = intent.resolveActivity(context.getPackageManager());return componentName != null;
}

/**打开计算器*/
public void openJS(){//可以通过下面方法获取手机应用 判断是否存在
    PackageInfo pak = getAllApps(getActivity(), "Calculator","calculator"); //大小写
    if(pak != null){Intent intent = new Intent();intent = getActivity().getPackageManager().getLaunchIntentForPackage(pak.packageName);startActivity(intent);}else{Toast.makeText(getActivity(), "未找到计算器", Toast.LENGTH_SHORT).show();}
}public  PackageInfo getAllApps(Context context, String app_flag_1, String app_flag_2) {PackageManager pManager = context.getPackageManager();// 获取手机内所有应用
    List packlist = pManager.getInstalledPackages(0);for (int i = 0; i < packlist.size(); i++) {PackageInfo pak = (PackageInfo) packlist.get(i);if(pak.packageName.contains(app_flag_1)||pak.packageName.contains(app_flag_2)){return pak;}}return null;
}

/**
 * 打开日历应用
 */
public  void gotoCalendarApp(Context cnt) {try {Intent t_intent = new Intent(Intent.ACTION_VIEW);t_intent.addCategory(Intent.CATEGORY_DEFAULT);t_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK
                | Intent.FLAG_ACTIVITY_TASK_ON_HOME);t_intent.setDataAndType(Uri.parse("content://com.android.calendar/"), "time/epoch");cnt.startActivity(t_intent);} catch (Exception e) {e.printStackTrace();Toast.makeText(cnt, "打开日历失败", Toast.LENGTH_SHORT).show();}
}
