Navigation drawer is under other widgets

Navigation drawer is under other widgets - java

I'm trying to add fragment with Navigation drawer to the main activity, where are two buttons. However, when Navigation drawer is opened, buttons are above it. Moreover, Navigation drawer is not clickable, but buttons are.

ProgressBar does not appear in WebView located in Fragment ,how to show ProgressBar in WebView android?

Whenever, I enter the fragment, I am shown a blank space for a few seconds, then the webpage in the WebView shows up. It seems that the ProgressBar does not show.
Here's my XML file for the Fragment the WebView and ProgressBar is in
<?xml version="1.0" encoding="utf-8"?>
<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:orientation="vertical"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".FragmentThree">
<ProgressBar
android:id="#+id/progressbar"
style="#style/Widget.AppCompat.ProgressBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"/>
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent">
</WebView>
</RelativeLayout>
Here is the Java file for the Fragment Java implementation:
package com.example.task1;
import android.content.Context;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import androidx.fragment.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
public class FragmentThree extends Fragment {
private WebView webView;
private String URL;
private ProgressBar progressBar;
private OnFragmentInteractionListener mListener;
public FragmentThree(String url) {
// Required empty public constructor
this.URL = url;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_three, container, false);
initMain(view);
return view;
}
private void initMain(View view) {
webView = view.findViewById(R.id.webview);
progressBar = view.findViewById(R.id.progressbar);
progressBar.setMax(100);
webView.loadUrl(URL);
webView.setWebViewClient(new WebViewClient());
webView.setWebChromeClient(new WebChromeClient(){
#Override
public void onProgressChanged(WebView view, int newProgress) {
progressBar.setProgress(newProgress);
}
});
}
// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
if (mListener != null) {
mListener.onFragmentInteraction(uri);
}
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnFragmentInteractionListener) {
mListener = (OnFragmentInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnFragmentInteractionListener");
}
}
#Override
public void onDetach() {
super.onDetach();
mListener = null;
}
public interface OnFragmentInteractionListener {
// TODO: Update argument type and name
void onFragmentInteraction(Uri uri);
}
}
The code is mostly located under the initMain() function for clarification.
Any advice is greatly appreciated, thank you for reading!

Just declare ProgressBar below Webview like this
<?xml version="1.0" encoding="utf-8"?>
<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:orientation="vertical"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".FragmentThree">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent">
</WebView>
<ProgressBar
android:id="#+id/progressbar"
style="#style/Widget.AppCompat.ProgressBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"/>
</RelativeLayout>

How to add an onClickListener that would open a new activity to a Fragment activity

I'm fairly new to android studio so I will try to explain as best as I can.
I've made a menu using fragments, so my activity_home is a fragmented activity. Inside the fragmented activity I've created a button that, upon clicking, should open a new activity.
The problem is that I don't know how to implement the onClickListener inside the fragmented activity.
Every tutorial I went trough does it from the beginning.
This is my main activity:
package com.example.relja.diplomskirad;
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.Button;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new home(), "Home");
adapter.addFragment(new profil(), "Profil");
adapter.addFragment(new mapa(), "Mapa");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
This is my main xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
This is home.java where i want to put the onclick listener:
package com.example.relja.diplomskirad;
import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.app.AppCompatActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
public class home extends Fragment {
public home() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.activity_home, container, false);
}
}
And this is home xml where the button is:
<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context=".home">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="80dp"
android:orientation="vertical">
<LinearLayout
android:id="#+id/glavnaStranica1"
android:layout_width="match_parent"
android:layout_height="200dp"
android:orientation="horizontal"
android:gravity="center">
<ImageView
android:id="#+id/logoSlika"
android:layout_width="200dp"
android:layout_height="200dp"
android:src="#drawable/logo2"
android:layout_gravity="center"/>
</LinearLayout>
<LinearLayout
android:id="#+id/glavnaStranica2"
android:layout_width="match_parent"
android:layout_height="200dp"
android:orientation="horizontal"
android:gravity="center"
android:layout_marginStart="30dp">
<EditText
android:id="#+id/search"
android:layout_width="250dp"
android:layout_height="38dp"
android:hint="#string/search"
android:background="#drawable/ivica"
android:drawableLeft="#drawable/search"
android:drawablePadding="10dp"
android:inputType="text"
/>
<Button
android:id="#+id/dugme"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/dugme"
/>
</LinearLayout>
<Button
android:id="#+id/dugmeLogin"
android:layout_width="70dp"
android:layout_height="40dp"
android:text="#string/dugmeLogin"
android:layout_gravity="end"
android:layout_marginRight="10dp"
android:onClick="loginLogin"
style="?android:attr/borderlessButtonStyle"/>
</LinearLayout>
</RelativeLayout>

You can try this.. this will help
public class home extends Fragment {
private Button btn_dumge_login;
public home() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.activity_home, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
btn_dumge_login = view.findViewById(R.id.dumgeLogin)
btn_dumge_login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), TestActivity.class) ;
getActivity().startActivity(intent);
}
});
}
}

View view = inflater.inflate(R.layout.your_layout_file, container, false);
view.findViewById(R.id.button_id).setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
getContext().startActivity(new Intent(getContext(), YourNewActivity.class));
});
return view;
you can use this code in your fragment 'home' in onCreateView() method

You should select first the view you want to be navigated from, for example, the Button with id dugmeLogin
then your code should be something like that
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_home, container, false);
Button loginButton = view.findViewById(R.id.dugmeLogin);
loginButton.setOnClickListener(v -> {
// You code goes here
});
return view;
}
this is in your home.java

i've tried, how can i fix it ? anyone please help me. thanks.

Anyone else having similar problem. It appears the order in the XML matters too.
I had my NavigationView and after it I had a layout included and I couldn't click an item on the NavigationView.
After I switched them, so that my layout was being included AND THEN AFTER IT I had my NavigationView, it worked ...

this adapter.java
public class Adapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<DataModel> item;
public Adapter(Activity activity, List<DataModel> item) {
this.activity = activity;
this.item = item;
}
#Override
public int getCount() {
return item.size();
}
#Override
public Object getItem(int location) {
return item.get(location);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_buddies, null);
TextView txt_nama = (TextView) convertView.findViewById(R.id.custom_list_item_text1);
txt_nama.setText(item.get(position).getNama());
return convertView;
}
}

You need to create this type of your layout xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 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:id="#+id/drawer_layout"
android:layout_width="match_parent" android:layout_height="match_parent"
android:fitsSystemWindows="true" tools:openDrawer="start">
<FrameLayout
android:id="#+id/container"
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:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
</FrameLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_menu_bar"
app:menu="#menu/activity_menu_bar_drawer" />
</android.support.v4.widget.DrawerLayout>
In FrameLayout you need to replace all fragment one by one like
private void callFragment(Fragment fragment) {
fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
}
Note: You can write your Coordinator layout and other in fragment itself, may be helpful for you.

Viewpager in Dialog?

I'm trying to have a dialog where you can click a "next" button to swipe right to the next screen. I am doing that with a ViewPager and adapter:
final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.voicedialog);
dialog.setCanceledOnTouchOutside(false);
MyPageAdapter adapter = new MyPageAdapter();
ViewPager pager = (ViewPager) findViewById(R.id.viewpager);
pager.setAdapter(adapter);
However, I get a NullPointerException saying that pager is null. Why is this happening? Here is the Page Adapter class:
public class MyPageAdapter extends PagerAdapter {
public Object instantiateItem(ViewGroup collection, int position) {
int resId = 0;
switch (position) {
case 0:
resId = R.id.voice1;
break;
case 1:
resId = R.id.voice2;
break;
}
return collection.findViewById(resId);
}
#Override
public int getCount() {
return 2;
}
#Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == arg1;
}
}
Here's my layout for the DIALOG:
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
Let me know on how to avoid this situation.
PS: Each of the layouts that should be in the view pager look like this, just diff. text:
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/voice2"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:text="Slide 1!"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView2"
android:layout_gravity="center"
android:textSize="50sp" />
</RelativeLayout>

Without Using Enum Class
You should call findViewById on dialog. so for that you have to add dialog before findViewById..
Like this,
ViewPager pager = (ViewPager) dialog.findViewById(R.id.viewpager);
After solving your null pointer exception the other problem's solution here, if you wont use enum class you can use below code...
MainActivity.java

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.voicedialog);
dialog.setCanceledOnTouchOutside(false);

ViewPager pager = (ViewPager) dialog.findViewById(R.id.viewpager);
pager.setAdapter(adapter);
dialog.show();
}
});

Try by add header view to your listview (header will also scroll in this case), You need to do like this in your MainActivity :
View header = (View) getLayoutInflater().inflate(
R.layout.header_layout, null);
ImageView img=(ImageView)header.findViewById(R.id.imgView);
img.setBackgroundResource(R.drawable.icon);
mainListView.addHeaderView(header);
Or you can use DesignLibrary like here or here.

Add another view in your XML and position it above activity_main_drawer inside your DrawerLayout. The header is probably not supposed to scroll so it shouldn't be in your listview. Also, remove drawer_image from the listview item layout. Since it's not supposed to be in all the items.
<?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">
<include layout="#layout/toolbar" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/activity_main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/activity_main_container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
<LinearLayout
android:layout_width="#dimen/drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
android:orientation="vertical">
<ImageView
android:id="#+id/drawer_image"
android:layout_width="280dp"
android:layout_height="140dp"
android:src="#drawable/loading" />
<ListView
android:id="#+id/activity_main_drawer"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:choiceMode="singleChoice"
android:drawSelectorOnTop="true"
android:fastScrollEnabled="false"
android:listSelector="#drawable/selector_clickable_item_bg"
android:background="#color/global_bg_front"
/>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
Or use http://developer.android.com/reference/android/support/design/widget/NavigationView.html and add your image as header view.
navView = (NavigationView) findViewById(R.id.navView);
navView.inflateHeaderView(R.layout.myheader)
or in XML
app:headerLayout="#layout/myheader"
