Open first Link searched against a keyword

I have 2 activities in my app, First Activity is simple editText and submit Button, When I press submit, it launches webView Activity and searches the keyword entered in the first activity. Now I want to open the first link Automatically in webview.
public class MainActivity extends AppCompatActivity {
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClient());
String query = "firebase";// Get the text from EditText here
String url = "https://www.google.com/search?q="+query;
webView.loadUrl(url);
}
}

How can I display a pdf document into a TextView?

I want to read pdf files and display contents on TextView. is it possible ? or just show pdf into WebView or pdfViewer?
i want to do like it,
public class MainActivity extends Activity {
private TextView showText;
String url="http://www.adobe.com/devnet/acrobat/pdfs/pdf_open_parameters.pdf";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
showText= (TextView)this.findViewById(R.id.showtext);
showText.setText( ++ convertPdfTotext ++);
}
public void convertPdfTotext(View view)
{
}
}

If you want to use it in text view you can convert it with itext as string,but you'll loose formatting:
PdfTextExtractor parser =new PdfTextExtractor(new PdfReader("C:/Text.pdf"));
parser.getTextFromPage(3);
Use WebView instead and you can enable even zoom.
WebView mWebView=new WebView(MyPdfViewActivity.this);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginsEnabled(true);
mWebView.loadUrl("https://docs.google.com/gview?embedded=true&url="+LinkTo);

Loading local html file from asset folder into a webview

Trouble in loading local html file from asset into a webview. HTML page has javascript code, so I have used webview.setJavaScriptEnabled(true) to enable it. It loads the html page, but not all the widgets properly. Any suggestions...

public class ViewWeb extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
WebView wv;
wv = (WebView) findViewById(R.id.webView1);
wv.loadUrl("file:///android_asset/hello.html");
}
}

For your most basic PhoneGap app you should extend your main activity from DroidGap.
import com.phonegap.DroidGap;
public class Main extends DroidGap {
/** Called when the activity is first created. */
//private Button m_button;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.loadUrl("file:///android_asset/www/index.html");
}
}

I would suggest checking out this link for a series of tutorials using Phonegap within the Eclipse development environment. Once you are setup on eclipse, you only need to overide a few lines of code in the Android Activity class to call your web pages. Phonegap takes care of the rest in terms of opening up a webview class and rendering your html within it. You will no longer to code that yourself (as you've done above). The tutorials spell it out quite clearly. You can also add your own custom JavaScript interface methods as well. Again that's described in the tutorials. Hope this helps.

In your case there is a need to Embedding Cordova WebView on Android here is link for it
Modify your main Activity as
public class MainActivity extends Activity implements CordovaInterface {
CordovaWebView cwv;
/* Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
cwv = (CordovaWebView) findViewById(R.id.tutorialView);
cwv.loadUrl("file:///android_asset/www/index.html");
}
And in your layout replace your webview with
<org.apache.cordova.CordovaWebView
android:id="#+id/tutorialView"
android:layout_width="match_parent"
android:layout_height="match_parent" />

Image from WebView

i m getting a photo from the web,but i see it very large..how could i see it with zoom out?this is my code for webView:
public class gavros extends Activity {
WebView browser;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.efimerides);
browser =(WebView)findViewById(R.id.webview);
browser.loadUrl("http://...");
}}

Checkout WebView's setInitialScale method:
