How to Set Linear Layout with WebView for onClickListener

I have a linear layout carrying webview. I have set the id of the LinearLayout to 'lay001'.
My intention is to set the onClickListener of the layout so that onclick, the intent will send data to webview and then to the url i specified.
All my efforts to make it work failed me. Please help me set the java code. Thanks
activity_main.xml
<LinearLayout
android:id="#+id/lay001"
android:layout_width="0dp"
android:layout_height="50dp"
android:layout_weight="1"
android:layout_margin="4dp"
android:orientation="vertical"
android:background="#drawable/layout_bg1">
<WebView
android:id="#+id/webview001"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:accessibilityPaneTitle="The Liturgy"
android:layout_marginTop="2dp">
</WebView>
<TextView
android:id="#+id/textView001"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="top"
android:text="Anglican Hymns Tunes"
android:textSize="10sp"
android:textStyle="italic|bold"
android:textAlignment="center"
android:textColor="#DD1A1A"/>
</LinearLayout>
MainActivity.java
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;
import android.widget.TextView;
public class MainActivity extends Activity {
private WebView webview;
private LinearLayout myLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myLayout.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
webview = (WebView001) findViewById(R.id.webview001);
webview.setWebViewClient(new WebViewClient());
webview.loadUrl("http://www.google.com");
}
}
});
}
}

You are missing findViewById() of linearlayout.
Try this out :
private LinearLayout myLayout;
myLayout= (LinearLayout) findViewById(R.id.lay001);
Also change this :
webview = (WebView) findViewById(R.id.webview001);
To load url :
myLayout.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
mWebview.loadUrl("your url");
}
});

I have some issue about WebView

I can't use WebView correctly. When I run my app there is "What to use" window and buttons "Browser, Chrome, Sorting" On Clicking "Отмена"/"Cancel" there is nothing happen. There are no errors in my code and I really don't know how to use WebView correctly. Please help me. "What to use" window
But I add WebView and I want to show everything in it. There is my code:
Main_Activity.java
package com.admin.zabroshki;
import android.annotation.SuppressLint;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebView;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#SuppressLint("ResourceType")
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
// получим идентификатор выбранного пункта меню
int id = item.getItemId();
String urlVK = new String("https://vk.com/zabroshkiborika");
String urlInstagram = new
String("https://instagram.com/zabroshkiborika");
WebView view = (WebView) findViewById(R.id.webView);
view.getSettings().setJavaScriptEnabled(true);
view.getSettings().setLoadWithOverviewMode(true);
view.getSettings().setUseWideViewPort(true);
switch (id)
{
case R.id.urlVK:
view.loadUrl(urlVK);
break;
case R.id.Instagram:
view.loadUrl(urlInstagram);
break;
}
return false;
}
}
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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.admin.zabroshki.MainActivity">
<WebView
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>

You try this.
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setAllowContentAccess(true);
settings.setDomStorageEnabled(true);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl("https://vk.com/zabroshkiborika");

Is there anything wrong or missing on my code? Please help

your CircularImageView is not inflated and there was so many problems about it, solution use alternative library like hdodenhof CircularImageView link
add this to your dependencies :
compile 'de.hdodenhof:circleimageview:2.1.0'
and add the view like this :
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/profile_image"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="#drawable/profile"
app:civ_border_width="2dp"
app:civ_border_color="#FF000000"/>

Swipable tab is not swiping in android

I'm trying to create a navigation drawer with swipe tab. But my viewpager is not working fine. I can only select the tab. Viewpager can not load any fragment. so I can not swipe it. If i change the height of the viewpager it hides the tab and load all the fragment.

You shouldn't use FrameLayout as container for the tab + pager. FrameLayout is used mostly to put views above others. To fix it you should change this FrameLayout to LinearLayout with vertical orientation. Also the view page height should be match_parent.
