Android如何在連接上顯示吐司時間

Question

我正在使用下面的代碼來檢查Android中的連接超時時間。最重要的是，如果連接實際超時，我該如何顯示吐司？任何建議？

/*Client timeout*/ 
HttpParams httpParameters = new BasicHttpParams(); 
// Set the timeout in milliseconds until a connection is established. 
// The default value is zero, that means the timeout is not used. 
int timeoutConnection = 3000;  //3Seconds 
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection); 
// Set the default socket timeout (SO_TIMEOUT) 
// in milliseconds which is the timeout for waiting for data. 
int timeoutSocket = 5000;   //5Seconds 
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket); 
/*Client timeout ends*/ 

final HttpClient client = new DefaultHttpClient(httpParameters);

//HOW TO SHOW TOAST MESSAGE WHEN THIS CASE ACTUALLY OCCURS ?? 

Answer 1

您可以使用try catch塊。

try{ 
    //your code of making request 
} 
catch (ConnectTimeoutException e) { 
    Toast.makeText(context, "Connection timed out.", Toast.LENGTH_SHORT).show();  
} 

確保從活動中傳遞適當的上下文。

希望這會有所幫助。
