Android常用代码

一、通过意图打开网络设置

startActivity(new Intent(Settings.ACTION_SETTINGS));

二、判断网络是否可用

ConnectivityManager conMan = (ConnectivityManager) mActivity.getSystemService(Context.CONNECTIVITY_SERVICE);NetworkInfo netWorkInfo = conMan.getActiveNetworkInfo(); // 获取可用的网络信息if (netWorkInfo != null) {// 判断网络是否连接if (netWorkInfo.isConnected()) {mTextView.setVisibility(View.GONE);return;}}
