我有我的活動意圖啓動的問題。看來，當我在autoGO方法運行這段代碼兩個活動奇怪開始
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClass(this, contentScreen.class);
startActivity(intent);
finish();
，它運行兩個活動，我知道這是我的logcat的告訴我：
11-03 11:16:16.542: INFO/ActivityManager(58): Displayed activity three.three/.contentScreen: 2030 ms (total 3391 ms)
11-03 11:16:16.713: INFO/ActivityManager(58): Displayed activity three.three/.contentScreen: 1596 ms (total 1596 ms)
我的流程基本上是在這個活動如果數據庫中的特定值爲true，它會自動運行autoGO，它在autoGO中啓動一個新的intent並將我帶到該類。不過，這似乎是我開始兩個活動的地方。因此，我打開了兩個相同類型的活動，但這是不需要的。這可能是什麼原因？
這裏是autoGO方法：
public void autoGO(View arg1) throws IOException,
XmlPullParserException {
EditText username = (EditText) findViewById(R.id.widget40);
EditText password = (EditText) findViewById(R.id.widget37);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//gainString(remembered);
setUserPass();
System.out.println(Compare[1]);
System.out.println(Compare[2]);
request.addProperty("User", Compare[1]);
request.addProperty("Password", Compare[2]);
autoSign = false;
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL);
httpTransport.debug = true;
httpTransport.call(SOAP_ACTION, envelope); // send request
SoapObject result = (SoapObject) envelope.getResponse(); // get
System.out.println(result);
int Conversion = Integer.parseInt(result.getProperty(0).toString());
System.out.println(Conversion);
if (Conversion > 0) {
try{
sqlDB=openOrCreateDatabase(DBNAME1,Context.MODE_PRIVATE,null);
System.out.println("open or create database");
//sqlDB.execSQL("UPDATE " + Table1 + " SET NAME = '" + sUserName + "' WHERE NAME = '" + remembered[1] + "'");
System.out.println("URL updated");
//sqlDB.execSQL("UPDATE " + Table1 + " SET PASSWORD = '" + sPassword + "' WHERE PASSWORD = '" + remembered[2]+ "'");
sqlDB.execSQL("UPDATE " + Table1 + " SET URL = '" + "http://" + result.getProperty(2).toString()+ "'");
System.out.println("HERE IS THE NEW URL " + "http://" + result.getProperty(2).toString());
contentScreen co = new contentScreen();
co.signAuto(true);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClass(this, contentScreen.class);
startActivity(intent);
finish();
}
catch (Exception e1) {
// TODO Auto-generated catch block
System.out.println("Problem "+ e1.getMessage());
e1.printStackTrace();
}
finally
{
sqlDB.close();
}
} else {
username.setTextSize(10);
username.setText("Invalid username or passcode!");
}
}
