Jak załadować zewnętrzną stronę internetową wewnątrz WebView
Mój problem polega na tym, że strona nie jest ładowana wewnątrz webview.
mWebview.loadUrl("http://www.google.com");
uruchamia przeglądarkę internetową...
Oto kod mojej aktywności:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class Main extends Activity {
private WebView mWebview;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.loadUrl("http://www.google.com");
setContentView(mWebview);
}
}
Dodałem wymagane pozwolenie w manifeście:
<uses-permission android:name="android.permission.INTERNET" />

Dzięki temu postowi w końcu znalazłem rozwiązanie. Oto kod:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebResourceError;
import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
import android.annotation.TargetApi;
public class Main extends Activity {
private WebView mWebview ;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
@SuppressWarnings("deprecation")
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
@TargetApi(android.os.Build.VERSION_CODES.M)
@Override
public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
// Redirect to deprecated method, so you can use it in all SDK versions
onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
}
});
mWebview .loadUrl("http://www.google.com");
setContentView(mWebview );
}
}

Spróbuj tego
Webviewlayout.xml:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/help_webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="none"
/>
W Twojej aktywności:
WebView webView;
setContentView(R.layout.webviewlayout);
webView = (WebView)findViewById(R.id.help_webview);
webView.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://www.google.com");
Update
Dodaj webView.setWebViewClient(new WebViewController());
do swojej aktywności.
Klasa WebViewController:
public class WebViewController extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}

Proszę użyć tego kodu: -
Main.Xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/background">
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="@drawable/top_heading"
android:id="@+id/rlayout1">
<TextView android:layout_width="wrap_content"
android:layout_centerVertical="true" android:layout_centerHorizontal="true"
android:textColor="#ffffff" android:textSize="22dip"
android:textStyle="bold" android:layout_height="wrap_content"
android:text="More Information" android:id="@+id/txtviewfbdisplaytitle" />
</RelativeLayout>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_below="@+id/rlayout1"
android:id="@+id/rlayout2">
<WebView android:id="@+id/webview1" android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1.0" />
</RelativeLayout>
</RelativeLayout>
Główna aktywność.Java
public class MainActivity extends Activity {
private class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Button btnBack;
WebView webview;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview=(WebView)findViewById(R.id.webview1);
webview.setWebViewClient(new MyWebViewClient());
openURL();
}
/** Opens the URL in a browser */
private void openURL() {
webview.loadUrl("http://www.google.com");
webview.requestFocus();
}
}

Możesz zrobić tak.
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("Your URL goes here");

To bardzo proste spróbuj zintegrować te linie kodu najpierw weź uprawnienia w pliku Manifest Androida
<uses-permission android:name="android.permission.INTERNET" />
To napisz jakiś kod w swojej aktywności .xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.MainActivity">
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/help_webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>
Następnie napisz ten kod w swojej głównej aktywności.java
import android.app.Activity;
import android.content.Intent;
import android.content.res.Resources;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Window;
import android.webkit.WebResourceRequest;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class MainActivity extends Activity{
private WebView mWebview ;
String link = "";// global variable
Resources res;// global variable
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_modernherbal_main);
mWebview = (WebView) findViewById(R.id.help_webview);
WebSettings webSettings = mWebview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
mWebview .loadUrl("http://www.example.com");
}
}

Po prostu wejdź do pliku XML i podaj id do swojego webView ' a następnie w Javie wklej tę linię:
public class Main extends Activity {
private WebView mWebview;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.Your_layout_file_name);
mWebview = (WebView)findViewById(R.id.id_you_gave _to_your_wenview_in_xml);
mWebview.loadUrl("http://www.google.com");
}
}

Try this;
webView.loadData("<iframe src='http://www.google.com' style='border: 0; width: 100%; height: 100%'></iframe>", "text/html; charset=utf-8", "UTF-8");

Dodaj poniżej metodę w klasie aktywności.Tutaj przeglądarka to nic innego jak Twój obiekt webview.
Teraz możesz łatwo przeglądać strony www.
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && browser.canGoBack()) {
browser.goBack();
return true;
}
return false;
}
