Downloading a website to a string
android, contain, download, eclipse, web
Solution
You can get the text using InputStream Reader like this.
try
{
URL url = new URL("http://yourwebpage.com");
// Read all the text returned by the server
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String str;
while ((str = in.readLine()) != null)
{
// str is one line of text; readLine() strips the newline character(s)
// You can use the contain method here.
if(str.contains(editText.getText().toString))
{
You can perform your logic here!!!!!
}
}
in.close();
} catch (MalformedURLException e) {
} catch (IOException e) {
}
Also add an additional permission in your apps Manifest file:
<uses-permission android:name="android.permission.INTERNET/>
//============================EDIT================================//
if (group.length() > 0)
{
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage("Bezig met checken voor roosterwijzigingen...");
mProgressDialog.show();
try
{
URL url = new URL("http://www.augustinianum.eu/roosterwijzigingen/14062012.pdf");
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String str;
while ((str = in.readLine()) != null){
if(str.contains(mEtxtGroup.getText().toString())){
if(mProgressDialog.isShowing())
{
mProgressDialog.dismiss();
}
Toast.makeText(this, "U hebt een roosterwijziging.", Toast.LENGTH_LONG).show();
break;
}
}
in.close();
} catch (MalformedURLException e) {
Toast.makeText(this, "Er is een fout opgetreden, probeer opniew.", Toast.LENGTH_LONG).show();
} catch (IOException e) {
Toast.makeText(this, "Er is een fout opgetreden, probeer opniew.", Toast.LENGTH_LONG).show();
}
if(mProgressDialog.isShowing())
{
mProgressDialog.dismiss();
}
}
else{
Toast.makeText(this, "Voer een klas in", Toast.LENGTH_LONG).show();
}
Problem
Having done some basic tutorials, I started making my first real android app in eclipse. I want this app to check if the text in an EditText matches the text on a website (this one: http://www.augustinianum.eu/roosterwijzigingen/14062012.pdf (it contains my school's schedule changes)). I've found out how to make the app check if the text in the EditText matches a string (with the method contains()), so now the only thing I need to do is to download all of the text of that website to a string. But I have no idea how to. Or is there maybe a method which I can check with if a website contains a certain word without downloading the website's text to a string. Thank You! (BTW I'm not English so plz forgive me if I've made some language-related mistakes.) @androider I can't post my code in the comment box so here it is: ``` package me.moop.mytwitter; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.MalformedURLException; import java.net.URL; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; import android.app.Activity; import android.app.ProgressDialog; public class MainActivity extends Activity { Button mBtnCheck; EditText mEtxtGroup; ProgressDialog mProgressDialog; TwitterUser mTwitterUser; TextView mTxtv1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.nicelayout3); mBtnCheck = (Button) findViewById(R.id.btnCheck); mEtxtGroup = (EditText) findViewById(R.id.etxtGroup); mTxtv1 = (TextView) findViewById(R.id.textView1); } public void checkScheduleChange(View view){ if (view == mBtnCheck){ String group; group = mEtxtGroup.getText().toString(); if (group.length() > 0){ mProgressDialog = new ProgressDialog(this); mProgressDialog.setMessage("Bezig met checken voor roosterwijzigingen..."); mProgressDialog.show(); try { URL url = new URL("http://www.augustinianum.eu/roosterwijzigingen/14062012.pdf"); BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream())); String str; while ((str = in.readLine()) != null){ mProgressDialog.dismiss(); if(str.contains(mEtxtGroup.getText().toString())){ Toast.makeText(this, "U hebt een roosterwijziging.", Toast.LENGTH_LONG).show(); } else{ Toast.makeText(this, "U hebt geen roosterwijzigingen", Toast.LENGTH_LONG).show(); } } in.close(); } catch (MalformedURLException e) { Toast.makeText(this, "Er is een fout opgetreden, probeer opniew.", Toast.LENGTH_LONG).show(); } catch (IOException e) { Toast.makeText(this, "Er is een fout opgetreden, probeer opniew.", Toast.LENGTH_LONG).show(); } } else{ Toast.makeText(this, "Voer een klas in", Toast.LENGTH_LONG).show(); } } } } ``` Here are the button's properties: ``` <Button android:id="@+id/btnCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:clickable="true" android:onClick="checkScheduleChange" android:text="Check" > ```
