当网络不可用或禁用时，我的应用程序没有显示 toast 消息？我在下面插入了我的代码，它似乎没有检查连接是否可用。请帮助我，当网络可用时它工作正常，但是当我禁用我的网络时，它没有显示错误消息，没有其他网络可用。
if (position == 2)
{
final ConnectivityManager connMgr = (ConnectivityManager)
getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connMgr
.getActiveNetworkInfo();
android.net.NetworkInfo mobile1 =
connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if (activeNetworkInfo == null) {
Toast.makeText(LoginScreen.this, "No
Active Network",Toast.LENGTH_LONG).show();
} else {
if (activeNetworkInfo.isConnected()) {
btnLogin.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
String pinemptycheck = pin.getText().toString();
String mobileemptycheck = mobile.getText().toString();
if (pinemptycheck.trim().equals("")||
(mobileemptycheck.trim().equals("")))
{
Toast.makeText(getApplicationContext(), "Please Enter Correct Information",
Toast.LENGTH_LONG).show();
}
else
{
showProgress();
postLoginData();
}
}
});
} else if
(activeNetworkInfo.isConnectedOrConnecting()) {
Toast.makeText(LoginScreen.this, "network is Connecting", Toast.LENGTH_LONG)
.show();
} else if (mobile1.isAvailable()) {
btnLogin.setOnClickListener(new
OnClickListener() {
public void onClick(View view) {
showProgress();
postLoginData();
}
});
} else if (!mobile1.isAvailable()) {
Toast.makeText(LoginScreen.this,"No other Connection Found
",Toast.LENGTH_LONG).show();
btnLogin.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
Toast.makeText(LoginScreen.this," No other Connection Found", Toast.LENGTH_LONG).show();
}
});
