こんにちは、Asyncタスクを使って基本的なログインシステムを利用しようとしています。しかし、問題があるIm。 android.os.networkexceptionを乗り越えるために、私は非同期を使用しますが、私はこの状況で完全に間違って使用していると確信しています。android login async taskでエラーが発生する
package com.example.toknapp;
import java.util.ArrayList;
import org.apache.http.NameValuePair;
import org.apache.http.message.BasicNameValuePair;
import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class login2 extends Activity {
EditText un;
TextView error;
Button ok;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
un=(EditText)findViewById(R.id.et_un);
ok=(Button)findViewById(R.id.btn_login);
error=(TextView)findViewById(R.id.tv_error);
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
GetData task = new GetData();
task.execute();
}
});
}
private class GetData extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... urls) {
ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("username", un.getText().toString()));
//String valid = "1";
String response = null;
try {
response = CustomHttpClient.executeHttpPost("http://tokn.me/android_merchant_login.php", postParameters);
String res=response.toString();
// res = res.trim();
res= res.replaceAll("\\s+","");
//error.setText(res);
if(res.equals("1"))
error.setText("Correct Username or Password");
else
error.setText("Sorry!! Incorrect Username or Password");
} catch (Exception e) {
un.setText(e.toString());
}
return response;
}
}
}

doInBackground（）内でテキストを設定しないで、テキストを設定してからpostExecute（）で変更したい場合は、そこから削除してください。 –
