How can I add a button on a WebView?. I have a WebView and I want to show a popup. For that I need to add a button on the bottom-left corner of WebVew. How can I do this?
I would use a RelativeLayout. I like using it a lot. Its a great way to easily place and organize views,buttons,layouts,etc...
Some Example code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFD0">
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<Button
android:id="#+id/My_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true"
android:text="My Button!" />
</RelativeLayout>
I think the views and buttons will be drawn in order from top to bottom in the XML, but it may be the other way around.use margins like :
android:layout_marginLeft="15dip" and android:layout_marginBottom="10dip"
to help adjust the position.
What kind of content is in the WebView? Is it some HTML that you can control / modify?
If yes, just add a <button> tag and position it accordingly using CSS.
If no, use Wayner's solution.
package com.webview;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
import android.widget.Toast;
public class webview extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_PROGRESS);
WebView webview = new WebView(this);
Button btnTag = new Button(this);
btnTag.setText("Button");
btnTag.setId(1);
webview.addView(btnTag);
setContentView(webview);
webview.getSettings().setJavaScriptEnabled(true);
final Activity activity = this;
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
activity.setProgress(progress * 1000);
}
});
webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
Toast.makeText(activity, "Oh no! " + description,
Toast.LENGTH_SHORT).show();
}
});
webview.loadUrl("http://www.google.com/");
}
}

I am creating an Android application to work as a simple browser. The user enters a web address and then clicks a button. After this, the application should the website in the WebView. However, after the button is clicked, a notification pops up asking me to choose a browser to complete my action. [The options in the pop up are my default browser, mozilla, etc.]
However, I do not want to use any of them. What should I do ?
This is my .java file:
package com.example.all_in_one;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebView;
import android.widget.Button;
import android.widget.EditText;
public class SimpleBrowser extends Activity implements OnClickListener{
WebView myBrowser;
EditText URLaddress;
Button Go;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_browser);
myBrowser = (WebView) findViewById(R.id.WV);
URLaddress = (EditText) findViewById(R.id.webaddress);
Go = (Button) findViewById(R.id.go);
Go.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.go:
String address = URLaddress.getText().toString();
myBrowser.loadUrl("http://" + address);
break;
}
}
}
This is my .xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/LL1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="5" >
<EditText
android:id="#+id/webaddress"
android:inputType="textNoSuggestions"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
/>
<Button
android:id="#+id/go"
android:text="Go"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="4"
/>
</LinearLayout>
<WebView
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="#+id/WV"
android:layout_below="#+id/LL1" />
</RelativeLayout>
I have added the Internet permission in my Manifest file.
Please help. Thank you in advance.
You have to pass the WebViewClient class object to browser.setWebViewClient(new BrowserClient()) to open the links in the webview.
private class BrowserClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.d(tag, "shouldOverrideUrlLoading");
view.loadUrl(url);
return true;
}
}
and in your onCreate() call like this
myBrowser.setWebViewClient(new BrowserClient());
I am opening a simple flash based website in my webview using following code:
Java Code:
package com.sample.webview;
import android.app.Activity;
import android.app.ProgressDialog;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
public class SampleWebViewActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final WebView webView = (WebView) findViewById(R.id.webview);
final ProgressDialog progress = new ProgressDialog(this);
progress.setMessage("loading");
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setPluginsEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
progress.show();
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
progress.dismiss();
}
});
Button mButton = (Button) findViewById(R.id.button);
mButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
webView.loadUrl("http://www.fusioncharts.com/demos/features/#linkedcharts-for-easy-drill-down");
}
});
}
}
Main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:text="Load URL" />
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_margin="5dp" />
</LinearLayout>
Now when the page is loaded completely and i am trying to scroll down to view rest of the content, the webview is coming on top of "Load URL" button. Check the screenshot:
while it should look like:
Please suggest, what should i do so that it works correctly.
Edit: I am using a Galaxy Note(OSv2.3.5) with the latest version of both Flash Player and Adobe Air installed.
I have also tried this things but I think the only solution to do this is by using only a single webview in your xml, so, you don't have other native controls.
This is really broken on Android. If you try to use the Build in topbar it will also go behind the flash. I'd really recommend you go away (far away) from flash. There is some discussions about it on google groups and some on stackoverflow but all ends without any good results. The only good suggestion I found was using flash to cover other flash components =/
I am trying to find a code that will do a popup at the initial start up on an installed app. Much like a changelog that is starting to appear in more and more apps.
I have found some similar codes, but being a beginner I haven't been able to figure out where to exactly put the code in and I always have tons of errors that still do not work once I try and fix them.
I am working in Eclipse with an android project, and I'm using a webview to show a website.
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webview"
android:layout_height="fill_parent" android:layout_width="fill_parent" android:scrollbarAlwaysDrawVerticalTrack="false"/>
</LinearLayout>
Java File:
package com.A2Ddesigners.WhatThe;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.view.KeyEvent;
public class Whatthe extends Activity {
WebView webview;
/** Called when the activity is first created. */
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
webview.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.setWebViewClient(new HelloWebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.setInitialScale(50);
webview.getSettings().setUseWideViewPort(true);
webview.loadUrl("http://mdsitest2.com/");
}
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
}
Using My this code you can show popup on any type of view on intial time of activity.
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.PopupWindow;
public class PopupDispaly extends Activity {
private PopupWindow outComePopup;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tiwter_login);
final View anyView = findViewById(R.id.popo_up); // define heade your view
anyView.postDelayed(new Runnable() {
#Override
public void run() {
callFirstToolTip(anyView);
}
}, 5000); // hear you can put your delay time like 5000 mls
}
public void callFirstToolTip(View view) {
Log.i("Started Info","popup");
View layout = LayoutInflater.from(PopupDispaly.this).inflate(R.layout.popup_copy_delete, null); // define hear your layout file id.
LinearLayout layCopyDelete = (LinearLayout) layout.findViewById(R.id.layCopyDelete);// hear define your id of sub lay like LinearLayout.
outComePopup = new PopupWindow(layout);
outComePopup.setFocusable(true);
layCopyDelete.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
outComePopup.setWidth(layCopyDelete.getMeasuredWidth());
outComePopup.setHeight(layCopyDelete.getMeasuredHeight());
outComePopup.setBackgroundDrawable(getResources().getDrawable(android.R.color.transparent));
outComePopup.setOutsideTouchable(true);
outComePopup.showAsDropDown(view);
}
}
And my Custome View layout file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/got_it_bg"
android:layout_gravity="center_horizontal"
android:id="#+id/layCopyDelete"
android:layout_marginLeft="100dp"
android:orientation="horizontal">
</LinearLayout>
Sounds like you should use a custom dialog box. http://developer.android.com/guide/topics/ui/dialogs.html
There's a code example at the bottom of the page. To show it, you can call onCreateDialog(int) from inside your main activity in its onCreate() method.
PopupWindow.showAsDropDown() in a delayed process can solve this problem, you can execute the show popupWindow in onCreate() method by 0.5s delay.
You should use PopupWindow.showAtLocation but use the post method of the one of the views on your activity. you can also use the root view of the activity using findViewById(android.R.id.content).
You code should look like this:
View anyView = findViewById(R.id.anyView);
anyView.post(new Runnable()
{
#Override
public void run()
{
// Create and show PopupWindow
}
});
I am developing an android game application,I have implemented all the screens.Now i want to change the webview background color,Can anybody guide me.Here is my xml file

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="109px"
android:layout_marginTop="37px">
</Button>
</LinearLayout>
And My Java file is
package com.tli.roadtripbingo;
import android.app.Activity;

public class WebView1 extends Activity {
private Button Back;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.webview);
Back = (Button)findViewById(R.id.back);
WebView webView = (WebView) findViewById(R.id.webbrowser);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.vikingredning.no/skilt.aspx");
webView.setWebViewClient(new HelloWebViewClient());
}
class HelloWebViewClient extends WebViewClient
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
};
}
Thanks in advance

You can find answer here Change Background color and font color
WebView myWebView = (WebView) findViewById(R.id.myWebView);
myWebView.setBackgroundColor(Color.parseColor("#123456"));
You can make the WebView transparent like this:
WebView webView = (WebView) findViewById(R.id.webView);
webView.setBackgroundColor(Color.TRANSPARENT);
<LinearLayout
android:id="#+id/web_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/web_bg_color"
android:gravity="center" >
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
WebView mWebView = (WebView) findViewById(R.id.webview);
mWebView.setBackgroundColor(Color.TRANSPARENT);
mWebView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);
It worked for me in lollipop also.
try it once!
You may also want to reload the page after changing colors by using the reload() method:
webView.reload();
