After conducting thorough research on this matter, I stumbled upon an answer here. Despite following the provided solution, the process is still not functioning as expected. My goal is simple - to extract text from a webpage like Google and convert it into a string. Below is my code, integrating the aforementioned tutorial's code:
public class Searching_Animation_Screen extends ActionBarActivity {
TextView loading_txt;
Animation blink;
public String pre_split;
public String[] split_string;
TextView text;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_searchinganimationscreen);
ActionBar actionBar = getSupportActionBar();
actionBar.hide();
int width = getWindowManager().getDefaultDisplay().getWidth();
loading_txt = (TextView)findViewById(R.id.loading);
text =(TextView)findViewById(R.id.textView);
Typeface pacifico_typeface = Typeface.createFromAsset(getAssets(), "fonts/pacifico.ttf");
loading_txt.setTypeface(pacifico_typeface);
loading_txt.setTextSize(width / 20);
blink = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.blink);
loading_txt.setAnimation(blink);
Begin();
}
private void Begin() {
Intent SEARCH_INTENT = getIntent();
pre_split=SEARCH_INTENT.getStringExtra("Search_Text");
split_string = pre_split.split(" ");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_searchinganimationscreen, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class DownloadWebPageTask extends AsyncTask<String, Void, String> {
String google_url ="https://www.google.com/#safe=active&q=";
@Override
protected String doInBackground(String... urls) {
String response = "";
for (String url : urls) {
DefaultHttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse execute = client.execute(httpGet);
InputStream content = execute.getEntity().getContent();
BufferedReader buffer = new BufferedReader(
new InputStreamReader(content));
String s = "";
while ((s = buffer.readLine()) != null) {
response += s;
}
} catch (Exception e) {
e.printStackTrace();
}
}
return response;
}
@Override
protected void onPostExecute(String result) {
text.setText(Html.fromHtml(result));
//throw into summarizer
}
public void readWebpage(View view) {
DownloadWebPageTask task = new DownloadWebPageTask();
task.execute(new String[] {"www.google.com"});
}
}
}
Android Studio has pointed out that readWebpage is never utilized, as well as the actual DownloadWebPageTask class. Any suggestions? I aim for this class to execute immediately upon creation. Appreciate any help!
