How to make tabs with webview to load from a web address?

How to make tabs with webview to load from a web address? - java

I want to build an application in Android Studio. I have inside tabs:
| tab one | tab two | tab three |
...and each tab should load a webview page.
For example: tab one should load www.google.com, and tab two should load www.youtube.com, ...
How can I build this?

Here It Is
activity_main.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
MainActivity.java
import android.app.ActionBar;
import android.app.Activity;
import android.app.Fragment;
import android.os.Bundle;
public class MainActivity extends Activity {
// Declaring our tabs and the corresponding fragments.
ActionBar.Tab bmwTab, fordTab, toyotaTab;
Fragment bmwFragmentTab = new Fragment();
Fragment toyotaFragmentTab = new Fragment();
Fragment fordFragmentTab = new Fragment();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Asking for the default ActionBar element that our platform supports.
ActionBar actionBar = getActionBar();
// Screen handling while hiding ActionBar icon.
actionBar.setDisplayShowHomeEnabled(false);
// Screen handling while hiding Actionbar title.
actionBar.setDisplayShowTitleEnabled(false);
// Creating ActionBar tabs.
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Setting custom tab icons.
// Setting tab listeners.
bmwTab.setTabListener((ActionBar.TabListener) new Fragment1());
toyotaTab.setTabListener((ActionBar.TabListener) new Fragment2());
fordTab.setTabListener((ActionBar.TabListener) new Fragment3());
// Adding tabs to the ActionBar.
actionBar.addTab(bmwTab);
actionBar.addTab(toyotaTab);
actionBar.addTab(fordTab);
}
}
PagerAdapter.java
import android.app.ActionBar.Tab;
import android.app.Fragment;
import android.app.FragmentTransaction;
import android.app.ActionBar;
public class PagerAdapter implements ActionBar.TabListener {
private Fragment fragment;
// The contructor.
public PagerAdapter (Fragment fragment) {
this.fragment = fragment;
}
// When a tab is tapped, the FragmentTransaction replaces
// the content of our main layout with the specified fragment;
// that's why we declared an id for the main layout.
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
ft.replace(R.id.activity_main, fragment);
}
// When a tab is unselected, we have to hide it from the user's view.
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
ft.remove(fragment);
}
// Nothing special here. Fragments already did the job.
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
}
activity_fragment1.xml
<RelativeLayout 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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.ss.tabswithwebview.Fragment1">
<WebView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/webView">
</WebView>
</RelativeLayout>
Fragment1.java
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
public class Fragment1 extends android.support.v4.app.Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_fragment1, container, false);
WebView webView=(WebView)rootView.findViewById(R.id.webView);
webView.loadUrl("www.google.com");
return rootView;
}
}
Similarly create different fragment as created above.

Actually FragmentActivites Need To Be Created
and in Your layouts You neeed to SetBackground As Your Wish Color So That activity_main is not loaded Along With FragmentLayout
And for Webview
Just Add Webview And Load Url In each fragments According to Yourself

My codes
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.app.ActionBar;
public class Adapter implements ActionBar.TabListener {
private android.support.v4.app.Fragment fragment;
// The contructor.
public Adapter(android.support.v4.app.Fragment fragment) {
this.fragment = fragment;
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
ft.replace(R.id.activity_main, fragment);
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
ft.remove(fragment);
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
}
When a tab is tapped, the FragmentTransaction replaces the content of our main layout with the specified fragment; that's why we declared an id for the main layout.

Showing a .swf file in a WebView

can somebody help me please to show a .swf file into a WebView, I tried to do, but it shows a white windows instead of WebView. Also I tried to show a simple website and it shows also a empty window.

Thank you!

SWF is a ShockWaveFlash file. Web browsers can not run/display a ShockWave Flash File without the help of the Flash Plugin.
The Flash Plugin for Android has been discontinued several years ago. Therefore you won't succeed in making it run in a WebView.
Hence you have to re-think your application design and how you can achieve whyt you want without that SWF file.
Anyway it is not a good idea to start a new app using a technology the will reach its end of life in 2 years (end of 2020).

Please help me to solve this so i can change fragment when menu on navigation drawer is clicked.

Try to call the openFragment() in the onItemTouchListener of the recycler view. Before loading the fragment try to close the drawer and then call the openFragment(). I think it should work. Also check whether the container id is correct.

Android Studio Onclick and fragment does not work

When I click on my Travel button it should replace the Menufragment with the TravelFragment. But for some reason it doesnt work and I dont know if the issue is from the onClicklistener or the way i replace fragments. And when I debug it complains in line 32, "View root = inflater.inflate(R.layout.fragment_menu, container, false);" is the code I have.
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.content.Intent;
import android.os.Bundle;
import android.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MenuFragment extends Fragment {
public MenuFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View root = inflater.inflate(R.layout.fragment_menu, container, false);
Button TravelButton = (Button) root.findViewById(R.id.travel);
TravelButton.setOnClickListener(buttonListener);
return root;
}
private View.OnClickListener buttonListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
switch (v.getId() ){
case R.id.travel:{
TravelFragment newFragment = new TravelFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.container, newFragment);
transaction.addToBackStack(null);
transaction.commit();
}
break;
}
}
};
}
And this is my xml code for my mainactivity (The FrameLayout is inside a RelativeLayout for containing the container where I can replace fragments for example:
<RelativeLayout 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">
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"></FrameLayout>
</RelativeLayout>
I cant find the problem. Please help. Im new to Android Studio so be patient with me! All help is welcome.

Try using this code by adapting it:
frag_results frag_results = new frag_results();
FragmentManager manager = getActivity().getSupportFragmentManager();
manager.beginTransaction().replace(R.id.framelayout_secundary, frag_results, frag_results.getTag()).commit();

put tabs in the bottom of screen

I want to put tabs at the bottom part of my screen . For this purpose I have the following code :
package info.androidhive.tabsswipe;
import info.androidhive.tabsswipe.adapter.TabsPagerAdapter;
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.os.Bundle;

public class MainActivity extends FragmentActivity implements
ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Top Rated", "Games", "Movies" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter) ;
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
By this code , I have the following layout :

// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
By this code , This is how the screen looks after compilation :
How can I put tabs at the bottom of the screen ?

Actually it's against Android Design Guideline since at bottom there are soft/hard buttons like back button home button etc.
http://developer.android.com/design/patterns/pure-android.html
But if you insist on to put them at the bottom, you can implement it like GitHub example consists tabs in bottom, using FragmentTabHost.
https://github.com/rameshkec85/BottomTabsFragmentTabHost

These sample xml code defines move tab to bottom of the screen:
<?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" >
<TabHost
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#android:id/tabs" >
<FrameLayout
android:id="#+id/tab_home"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<FrameLayout
android:id="#+id/tab_video"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />

android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</FrameLayout>
<FrameLayout
android:id="#+id/tab_more"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</FrameLayout>
</FrameLayout>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" //align parent bottom mainly used for move the tab to bottom of the screen.
android:background="#drawable/ic_launcher"
android:divider="#null" />
<!-- android:background="#d8e49c" -->
</RelativeLayout>
</TabHost>
</LinearLayout>

with an action bar you will only be able to add tabs at the top, since that is the way android apps should look like. Having tabs at the bottom is purely ios style. and if you still wish to achieve the same look at :
this.
Github source can be found here

Don't do this, tabs should always be at the top in Android.

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.input, container,false);
submit = (Button)view.findViewById(R.id.input_submit_button);
submit.setOnClickListener(new SubmitButtonAction());
return view;
}
private class SubmitButtonAction implements OnClickListener
{
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Fragment frag = new OutputFragment();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.fragment_container, frag);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.addToBackStack(null);
ft.commit();
}
}
}
There is an compile error. Here it is.
Type mismatch: cannot convert from android.app.FragmentTransaction to android.support.v4.app.FragmentTransaction
This error is coming from FragmentTransaction ft = getFragmentManager().beginTransaction(); of MainActivity.java
I tried fixes suggested by Eclipse, but it gave me nothing. When I fix the error using exlipse suggestions, it gives another error. When I fix it using eclipse suggestions (clicking on eclipse suggestions) it comes back to the previous error.
What am I doing here wromg?

Try to use getSupportFragmentManager() instead of getFragmentManager()

If you want to use fragments below Android sdk vrsion 3.0,then use getSupportFragmentManager() method available in support 4 support lib.
(Make sure to put supportv4 lib in your lib folder and add in your project build path)

I'm not sure you can use transition with the support library. A few suggestions:
Remove this line ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
Or if you're targeting API 14 or higher you may instead extend Activity and use getFragmentManager()

How to make tabs with webview to load from a web address? - java

I want to build an application in Android Studio. I have inside tabs: | tab one | tab two | tab three | ...and each tab should load a webview page. For example: tab one should load www.google.com, and tab two should load www.youtube.com, ... How can I build this?

Actually FragmentActivites Need To Be Created and in Your layouts You neeed to SetBackground As Your Wish Color So That activity_main is not loaded Along With FragmentLayout And for Webview Just Add Webview And Load Url In each fragments According to Yourself
