My webview doesn't start after creating progress bar

I created my new webapp. It worked well. But I wanted to add a progress bar. The progress bar works, but my webview doesn't show anynore. I don't understand why. Can someone may help, please?
I tried all the codes I found online. They are ok for the others, but not for me.

I didn't use SwipeRefreshLayout, but the documentation says you need to include another layout inside it. As you added a second view inside, you are now using it as a default ViewGroup, which is probably not working as expected. Put a LinearLayout or whatever inside the SwipeRefreshLayout and your components inside your LinearLayout.

Android Webiew App show image before loading site

I'm fresh for Android App. I done my first Webview app. Now want to add Loading Image(.jpg), before the website load. I don't know anything. Just explain clearly. Image may add in app or image from another source.
My activity_main.xml
<FrameLayout 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:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".MainActivity">
<TextView android:text="#string/hello_world" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<WebView
android:id="#+id/activity_main_webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
AndroidManifest.xml is below,
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.steptoinstall.steptoinstall" >
<application

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
MainActivity.java is below,
package com.steptoinstall.steptoinstall;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends ActionBarActivity {
private WebView mWebView;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
mWebView.loadUrl("http://www.steptoinstall.com");
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);

mWebView.setWebViewClient(new WebViewClient());
}

getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {

// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
return super.onOptionsItemSelected(item);
}
}

I think the easiest way to do it is to place an imageView over the webView and then when the site loaded, hide it.
First of all u must change your xml like this:
<FrameLayout 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:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin">
<WebView
android:id="#+id/activity_main_webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ImageView
android:id="#+id/activity_main_imageview"
android:layout_height="match_parent"
android:layout_width="match_parent" />
</FrameLayout>
and add this line to your main activity
mWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
// hide your imageView
}
});
just let me know if u wanted more details.
Update 2:
In your MainActivity, after setContentView, add this:
final ImageView mImageView = (ImageView)findViewById(R.id.activity_main_imageview);
after that u can set image to this imageView in xml or in code:
in xml change your ImageView:
<ImageView
android:id="#+id/activity_main_imageview"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:src="#drawable/img" />
and your MainActivity should be this:
mWebView = (WebView) findViewById(R.id.activity_main_webview);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
mWebView.loadUrl("http://www.steptoinstall.com");
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
mImageView.setVisibility(View.GONE);
}
});

To add Splash screen before loading main activity. then add this
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import com.example.tabs.R;
public class Splash extends Activity implements Runnable
{
Thread mThread;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
mThread = new Thread(this);
mThread.start();
}
#Override
public void run()
{
try
{
Thread.sleep(2000);
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
startActivity(new Intent(Splash.this, MainActivity.class));
finish();
}
}
}
and 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"
android:background="#drawable/splash" >
</LinearLayout>

How to make a web page into a android app

Hi I'm trying to make a web based app but i'm a beginner and not 100% sure what i'm doing right now please could you guide me there are no errors but it says the app is not responding when I run it
Main Java
package com.theverge.www.theverge;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import static com.theverge.www.theverge.R.id.*;
public class TheVerge extends Activity {
private WebView the_verge;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_the_verge);
the_verge = (WebView) findViewById(activity_the_verge_webview);
// Enable Javascript
WebSettings webSettings = the_verge.getSettings();
webSettings.setJavaScriptEnabled(true);
// Force links and redirects to open in the WebView instead of in a browser
the_verge.setWebViewClient(new WebViewClient());
the_verge.loadUrl("http://www.theverge.com");
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_the_verge, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Here is the xml for the main activity
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView android:text="" android:layout_width="wrap_content"
android:layout_height="wrap_content" />

You need to add a WebView to your layout file. Change it to something like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"
android:id="#+id/activity_the_verge_webview"
android:layout_height="match_parent" android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".TheVerge">
<WebView
android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentStart="true"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" />
And then replace your onCreate() method with this one
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_the_verge);
the_verge = (WebView) findViewById(webView1);
// Enable Javascript
WebSettings webSettings = the_verge.getSettings();
webSettings.setJavaScriptEnabled(true);
// Force links and redirects to open in the WebView instead of in a browser
the_verge.setWebViewClient(new WebViewClient());
the_verge.loadUrl("http://www.theverge.com");
}

You are trying to asign your relativelayout to a webview variable here:
the_verge = (WebView) findViewById(activity_the_verge_webview);
You need to add a webview to the layout and give it a id
Asign the webview variable to the id you just used in 1.
Also if you plugin your device to a computer you get a crashlog in your program :)

You have defined textview instead of webview in your xml.Try this out...
xml layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

android:orientation="vertical" >
<WebView
android:id="#+id/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>

Thank you..

Why do you override the setContentView method in your Creation class? Since you don't call it, it won't set the correct view.
You should call setContentView from onCreate, and as far as I know, there is no need to override setContentView.
Try this in Creation:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.creation);
}
