我正在登录农场,但我有一个问题,我不明白为什么 这是我的代码:
if (isNetworkOnline()) {
if (!(edtuserid.getText().toString().equals("") && !(edtpass.getText().toString().equals("")))){
DoLogin doLogin = new DoLogin();
doLogin.execute("");
Log.e("Login", "logining");
}else {
Log.e("Login","empty");
}
}else {
Log.e("Login", "no network");
}
它始终显示"登录"在logcat ...我试过setText到edtuserid =""和edtpass.getText => Logcat ="登录" ,转而使用wifi,然后显示"登录"
这是我的支票网络代码:
public boolean isNetworkOnline() {
boolean status=false;
try{
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getNetworkInfo(0);
if (netInfo != null && netInfo.getState()==NetworkInfo.State.CONNECTED) {
status= true;
}else {
netInfo = cm.getNetworkInfo(1);
if(netInfo!=null && netInfo.getState()==NetworkInfo.State.CONNECTED)
status= true;
}
}catch(Exception e){
e.printStackTrace();
return false;
}
return status;
}
答案 0 :(得分:1)
检查连接
public boolean isInternetOn() {
// get Connectivity Manager object to check connection
ConnectivityManager connec =
(ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
// Check for network connections
if ( connec.getNetworkInfo(0).getState() == android.net.NetworkInfo.State.CONNECTED ||
connec.getNetworkInfo(0).getState() == android.net.NetworkInfo.State.CONNECTING ||
connec.getNetworkInfo(1).getState() == android.net.NetworkInfo.State.CONNECTING ||
connec.getNetworkInfo(1).getState() == android.net.NetworkInfo.State.CONNECTED ) {
return true;
} else if (
connec.getNetworkInfo(0).getState() == android.net.NetworkInfo.State.DISCONNECTED ||
connec.getNetworkInfo(1).getState() == android.net.NetworkInfo.State.DISCONNECTED ) {
return false;
}
return false;
}
在您的代码中使用
if (isInternetOn()) {
if (edtuserid.getText().toString().length > 0 && edtpass.getText().toString().length > 0){
DoLogin doLogin = new DoLogin();
doLogin.execute("");
Log.e("Login", "logining");
}else {
Log.e("Login","empty");
edtuserid.setError("Invalid UserId!");
edtpass.setError("Invalid Password!");
}
}else {
Log.e("Login", "no network");
}
