I want to display webview below progressbar. How to do it ?
My code is as below :
<FrameLayout
android:id="#+id/flWeb"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<ProgressBar
android:id="#+id/pbWebsite"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|top" />
<WebView
android:id="#+id/wvWebsite"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</FrameLayout>
I used this and solved my problem...
<FrameLayout
android:id="#+id/flWebpre"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<WebView
android:id="#+id/wvWebsite"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<ProgressBar
android:id="#+id/pbWebsite"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/white"
android:layout_gravity="center_horizontal" />
</FrameLayout>
This is the code i have used to show the progress:
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity {
WebView mWvUrl;
#Override
protected void onCreate(Bundle savedInstanceState) {
final Activity activity=this;
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setContentView(R.layout.activity_main);
activity.setProgressBarIndeterminateVisibility(false);
mWvUrl = (WebView) findViewById(R.id.wv_url);
mWvUrl.getSettings().setJavaScriptEnabled(true);
Button btnLoad = (Button) findViewById(R.id.btn_load);
btnLoad.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
EditText etUrl = (EditText) findViewById(R.id.et_url);
mWvUrl.loadUrl(etUrl.getText().toString());
activity.setProgressBarIndeterminateVisibility(true);
}
});
mWvUrl.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
/** This prevents the loading of pages in system browser */
return false;
}
/** Callback method, executed when the page is completely loaded */
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
Toast.makeText(getBaseContext(),
"Page loaded Completely",
Toast.LENGTH_SHORT).show();
/** Hiding Indeterminate Progress Bar in the title bar*/
activity.setProgressBarIndeterminateVisibility(false);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
You need another Layout. The FrameLayout is not the better way to do alignement between components. If you are using a FrameLayout, components will be superimposed. I suggest you to use a LinearLayout vertical or a RelativeLayout.
Try this:
<?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" >
<ProgressBar
android:id="#+id/pbWebsite"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|top" />
<WebView
android:id="#+id/wvWebsite"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>

Good morning,

Everything works very well except for a small problem, the message Loading appears for a while and disappears, I want that remains until the total loading of the whole page (images ...).
Thanks for your help

Thank you
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 have an app with PopupWindow containing WebView that opens Facebook's page, any context menu like: the Autocomplete on text fields in the WebView or even the Long Press that should display options for the user to copy/paste/cut crashes the app right away with the follow error:

Notice: my understanding of the problem is that the context menu/window are shown actually in the scope of the app itself not inside the WebView using another PopWindow (Auto generated by the Core WebView Class) this class references the context incorrectly.
My Code is as follows:

As commented above in my answer you can use Custom dialog for your requirement.. i have created a sample PopupDialog.. please check and let me know..if it solve your purpose.. Autocomplete and ContextMenus will work as expected..
MyActivity.java
package com.example.testapp;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;

import android.widget.Button;
public class MyActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button btnOpenPopup = (Button) findViewById(R.id.openpopup);
btnOpenPopup.setOnClickListener(new Button.OnClickListener() {
#SuppressLint("NewApi")
#Override
public void onClick(View arg0) {
final PopupDialog popupDialog = new PopupDialog(MyActivity.this);
popupDialog.setContentView(R.layout.popup);
WebView popupWebview = (WebView) popupDialog.findViewById(R.id.webviewActionView);
popupWebview.setWebChromeClient(new WebChromeClient());
popupWebview.setWebViewClient(new WebViewClient());
popupWebview.loadUrl("http://m.facebook.com");
Button btnDismiss = (Button) popupDialog
.findViewById(R.id.dismiss);
btnDismiss.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
popupDialog.dismiss();
}
});
// popupDialog.showAtLocation(50,50);
popupDialog.showAsDropDown(findViewById(R.id.openpopup));
}
});
}
}
PopupDialog.java
package com.example.testapp;
import android.app.Dialog;
import android.content.Context;
import android.view.Gravity;
import android.view.View;

import android.view.WindowManager;
public class PopupDialog extends Dialog{
private final Context mContext;
public PopupDialog(Context context) {
super(context);
mContext=context;
requestWindowFeature(Window.FEATURE_NO_TITLE);
}
public void showAtLocation(int x,int y)
{
WindowManager.LayoutParams wmlp = getWindow().getAttributes();
wmlp.gravity = Gravity.TOP | Gravity.LEFT;
wmlp.x = x;
wmlp.y = y;
show();
}
public void showAsDropDown(View view)
{
float density = mContext.getResources().getDisplayMetrics().density;
WindowManager.LayoutParams wmlp = getWindow().getAttributes();
int[] location = new int[2];
view.getLocationInWindow(location);
wmlp.gravity = Gravity.TOP | Gravity.LEFT;
wmlp.x = location[0]+(int)(view.getWidth()/density);
wmlp.y = location[1]+(int)(view.getHeight()/density);
show();
}
}
edit: added popup.xml

yes i think you should use your activity name in place of "getBaseContext()". i am just created one demo with your code. its working fine in my pc. and when you are getting this exception?
Nothing wrong in your code..seems to be Android 4.1+ specific issue..
Webview is also using PopupWindow for showing Paste context menu in input box..Nested popupwindows through webview is causing WindowManager crash, while adding new view to it.
I have tried Custom Dialog(in place of Popupwindow) with embedded Webview, Paste context menu is coming fine in Android 4.1+..
If you are not so specific about this paste context menu you can disable it for particular android version using below code..i have tried it.. it will stop app from being crash..
popupWebView.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
if (Build.VERSION.SDK_INT >= 16)
return true;
return false;
}
});
Also you can look at Webview HitTestResult class for displaying some custom made Context menus, according to your needs..
I have created a WebViewActivity extending Activity and showing a WebView inside of my app instead of redirecting to the browser.
So I tried to use AsyncTask to show my ProgressBar while the view is loading. But the progress bar doesn't display at all. Here is the code I'm using:
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebView;
import android.widget.ProgressBar;
import android.widget.TextView;
import android.app.Activity;
public class WebViewActivity extends Activity {
WebView webView;
TextView textView;
ProgressBar bar;
private class Async extends AsyncTask<Void, Void, Void> {
protected Void doInBackground(Void... arg0) {
return null;
}
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
String url = new String(getIntent().getStringExtra("url"));
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.loadUrl(url);
textView.setText(getIntent().getStringExtra("title"));
bar.setVisibility(ProgressBar.INVISIBLE);
}
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_web_view);
vueText = (TextView) findViewById(R.id.barTitle);
vueWeb = (WebView) findViewById(R.id.WebView);
bar = (ProgressBar) findViewById(R.id.progressBar);
bar.setVisibility(ProgressBar.VISIBLE);
new Async().execute();
}
}
And here is my layout:
<?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="#color/grayBackground"
android:orientation="vertical" >
<TextView
android:id="#+id/barTitle" />
<ScrollView
android:id="#+id/sc1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/barTitle"
android:fillViewport="true" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<WebView
android:id="#+id/WebView"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</ScrollView>
<ProgressBar
android:id="#+id/progressBar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:visibility="visible" />
</RelativeLayout>
You should perform the background action (loading the URL) of the AsyncTask in the doInBackground() method.
The onPostExecute() is invoked on the UI thread so it will freeze the UI while running.
See the documentation of AsyncTask for more details.
You have to use pubishProgress() inside the doInBackground.
Then override onProgressUpdate
I am having this syntax error on token, delete this token error. Below are my two related files

Where is onCreate() of your Activity?
You forgot to define onCreate() of your Activity. (From your code)
Now try this,
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.loadUrl("www.yahoo.com");
}
}
UPDATE:
After updated your question,
myWebView.loadUrl("www.yahoo.com");
you can not initialize or declare any method directly outside of Activity's any method.
Just put this line in onCreate() after of setContentView(R.layout.activity_main);
as I write in my above code, Then its works.
