I am trying to make a simple app that starts the webbrowser on the right page. Simply enougth I found the code to do it right here on stackoverflow.
But there is a problem, if you open the website threw the app, then click home button and open the app again then nothing happens and the browser does not open.
Does anybody know away to force the browser in the foreground?
Edit: Extend question:
Here is the layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
And this is the MainActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
oWebView = (WebView) findViewById(R.id.webview);
oWebView.setWebViewClient(new WebViewClient());
oWebView.getSettings().setJavaScriptEnabled(true);
String url = "http://google.com";
oWebView.loadUrl(url);
}
My problem is with the fullscreen, the Webview does not extend to the hole screen. See the top right:
It doesn't really matter on this websites but on other it messes up the views.
Try this :
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
WebView oWebView = (WebView)findViewById(R.id.webView1);
oWebView.setWebViewClient(new WebViewClient());
oWebView.getSettings().setJavaScriptEnabled(true);
oWebView.loadUrl(your_url);
xml: android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
//or in code
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
WebView oWebView = (WebView)findViewById(R.id.webView1);
oWebView.setWebViewClient(new WebViewClient());
oWebView.getSettings().setJavaScriptEnabled(true);
oWebView.loadUrl(your_url);
onResume(){
oWebView.reload();
}

Am trying to Use button to Load html file from asset folder
but after clicking the button the html file refuse to load
Activity_main.xml
<Button
android:id="#+id/btn1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="open"
android:text="lawal"
android:textSize="20dp" />
<WebView
android:layout_width="368dp"
android:layout_height="495dp"
android:id="#+id/webView"
/>
Main.java
public class MainActivity extends AppCompatActivity {
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void open(View view) {
webView = (WebView)findViewById(R.id.webView);
WebView webView = new WebView(this);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.loadUrl("file:///Android_asset/1.html");
setContentView(view);
}
}
android_asset should be in lower case.Change your button onClick() code as below. here test.html should be replaced by your file name.
you need to create assets folder inside main folder.
WebView webView = view.findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.loadUrl("file:///android_asset/test.html");
Initialize the webview in oncreate after setting the content view
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
and then load your url in open function
webView.loadUrl("file:///android_asset/1.html");
I has activity with webView. Here layout xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
Here activity code:
public class TestActivity extends AppCompatActivity {
public static final String HTML_TEXT = "HTML_TEXT";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test_activity);
String htmlText = getIntent().getExtras().getString(HTML_TEXT);
WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
String resultHTML = "<html><head><meta charset=utf-8></head><body>" + htmlText + "</body></html>";
webview.loadDataWithBaseURL("fake://", resultHTML, "text/html", StringUtil.encodingUTF8, null);
}
}
And here result:
And as you can see on right side success show scrollbar when scrolling.
This work on Android 4.0, 5.0, 6.0, 7.0. OK.
But on Android 8.0 (Emulator) when scrolling to item "Test many posts 7/15" (about half screen) scrollbar is hide. I'm scrolling to bottom of screen but scrollbar not show.
Here result:
and scrolling to bottom of screen (scrollbar is hide):
How fix this?
in your onCreate() method try this :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_web_view_layout);
browser = (WebView)findViewById(R.id.your_webview);
WebSettings mWebSettings = browser.getSettings();
mWebSettings.setBuiltInZoomControls(true);
browser.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
browser.setScrollbarFadingEnabled(false);
browser.loadUrl("file:///android_asset/index.html");
}
I am developing an app and there is webview tab, on it i give zoom in out from .getSettings().setSupportZoom(true);. However when i zoom out (the view gets smaller and smaller until minus button(zoom out)disabled itself)the webview showing white background that i don't even set a background on the layout. how to make webview on zoom out have some resolution which will fit the height of the screen? and I am curious if we can make the zoom controls always seen?(it only appear whenever we touch the screen and make some move on it(tap, hold and move))
here is my java code from webview
public class WebViewActivity extends Activity {
private WebView webView;
//private static final FrameLayout.LayoutParams ZOOM_PARAMS = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT,Gravity.BOTTOM);
#Override
#SuppressLint("SetJavaScriptEnabled")
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setUseWideViewPort(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("http://www.somewebsitename.com");
}
}
and here is my xml code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<WebView
android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent">
</WebView>
</LinearLayout>

webView.getSettings().setDisplayZoomControls(true);
I am creating an application in which I have to use webView and display a HTML file saved in application in assets folder. This is my mainActivity code.
public class MainActivity extends Activity {
WebView browser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
browser = (WebView)findViewById(R.id.wv1);
browser.loadUrl("file:///android_asset/test.htm");
WebSettings webSettings = browser.getSettings();
browser.getSettings().setJavaScriptEnabled(true);
setContentView(browser);
}
}
and this is my xml file
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Test Application"
android:gravity="center_horizontal">
</TextView>
<WebView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/wv1"
android:layout_marginTop="3dp">
</WebView>
whin I am trying to run this application , it goes crash..
can any one please help me to find out what is the mistake i am doing.
You cannot call setContentView(browser) because browser is already a child of another view -- the LinearLayout.
If you don't need the other views, just change the layout xml file and remove them, leaving only the WebView. Otherwise, remove the setContentView(browser) line.
You're using setContentView() twice and supplying the view that already has a parent. That is why it is giving you the error saying call removeView() on the child's parent first. So remove setContentView(browser).
Your code should look like this.
public class MainActivity extends Activity {
WebView browser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
browser = (WebView)findViewById(R.id.wv1);
browser.loadUrl("file:///android_asset/test.htm");
browser.getSettings().setJavaScriptEnabled(true);
}
}
I am new to android development and i'm doing a an app where i need to embed an iframe in android's webview..
iframe sample is
<iframe src="//e.infogr.am/chart-61108188168" width="550" height="680" scrolling="no" frameborder="0" style="border:none;"></iframe>
Can you just set up a simple webview pointing to the iFrames url like so?
Create a webview in the xml:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
Then in your code set it up as:
public class WebActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webcontent);
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://websitesby.projectcaruso.com/");
}
}
