NavigationDrawer blocks/stops other buttons on the activity

NavigationDrawer blocks/stops other buttons on the activity - java

I'm creating an app where once you log in, you can click a button and it leads you to a quiz, however, the Profile activity (activity when you first log in) has a navigation drawer and for some reason, the navigation drawer is blocking the use of the buttons on the Profile that leads to the Quiz activity. Does anyone know how to fix this? If there's anything I can do please let me know. I'm sorry if this is a stupid question this is my first time coding an app.

DrawerLayout should be the parent if you're using NavigationView.
Put the RelativeLayout inside the DrawerLayout.
Your xml should look something like this:
<!-- Menu Drawer-->
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<!-- OTHER VIEWS -->
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/nav_header"
app:menu="#menu/navigation_menu" />
</android.support.v4.widget.DrawerLayout>

Toast.makeText(this, "Title added", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "You must give the note a title", Toast.LENGTH_SHORT).show();
}
}
}
I've made sure I don't have any duplicate edit text names and got rid of any classes and xml files that are no longer needed just to be sure.
I've cleaned and rebuilt I don't know how many times but can't get past this issue. Does anyone have any other ideas I can use/try?
Thanks

Here you have it twice!
<include
android:id="#+id/noteTitleTxt" // <-----------------
layout="#layout/content_note_taker" />
<EditText
android:id="#+id/noteTitleTxt" // <-----------------
Just remove the one id in your include tag. While not shown in your post, I bet its top container is RelativeLayout.

I am Currently developing an app for final year. No errors appear, but when i select my searchScreen the app crashes

I started to develop an app for my final year project. I created all the navigation drawers with no issue and they worked fine when I had run the program. When I added a search-page that would link in with the mapsAcivity I added. No errors are appearing however the app will run fine but when I click on the navigation drawer to access the search page and mapsActivity page the app crashes. Any ideas what the issue is?Screengrab of the app failing

The reason you're crashing is your ScrollView has more than one child element in it. You'll need to either wrap them both in a parent view sitting inside the ScrollView or move your DrawerLayout outside of the ScrollView.

I'm not sure exactly what you want your layout to look like but if you follow the above you shouldn't be crashing. Make sure you are using Code > Reformat Code to keep your indentations consistent. Good luck!

Sliding Menu Like Facebook in Material Design theme in Android

I have made a sliding menu like that of facebook by following the tutorial which is available in the following site:
http://www.devexchanges.info/2016/05/creating-your-own-sliding-menu-like.html?m=1
Now in the main layout I have added a long paragraph of text so in order to view everything I used ScrollView. But when I use ScrollView I cannot pull the menu out, I can only open the drawer by clicking on the button. Please help me on how to scroll through the para and also be able to pull the menu drawer.

try this instead of Fragments container. add this code below

ViewStub is Not Inflating and Layout Remains Blank - Android

I am working through the sample code that is generated when you start a Navigation Drawer Activity in Android Studio. What I am trying to do is change an included view programatically and my research has shown that ViewStub is the best way to do this. However I cannot get it working. For the main layout in question there are 3 files involved:

I have come across the same issue. It seems that when you are dynamically inflating the StubView, the behaviour is different than when you just use the <include> tag to include another xml layout. In this case, after being inflated the content that replaces the StubView is not positioned below the AppBar layout, but is positioned exactly behind it.
One way to solve this issue, is to move the RelativeLayout so that it wraps the StubView. So, the below changes are needed:
app_bar_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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.MY_APP.android.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<!-- Changed Content -->
<RelativeLayout
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"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/app_bar_main"
tools:context="com.MY_APP.android.MainActivity">
<ViewStub
android:id="#+id/main_content"
android:inflatedId="#id/main_content"
android:layout="#layout/content_main"
android:layout_height="match_parent"
android:layout_width="match_parent"/>
</RelativeLayout>

Cannot get a reference to EditText using 'findViewById()' after 'setContentView()'

In an activity where the user is supposed to enter his credentials, in the 'onCreate(...)' of activity, after setContentView(layout) I am doing this:
nameView = (EditText) findViewById(R.id.profileNameTextBox);
Where nameView is an EditText. When I try to get the text from this variable on a button click, my application crashes. The reason behind it is that nameView holds a null object reference. I can't really understand the reason behind because the function 'findViewById(...)' returns a valid reference to every other View object like Button, Spinner, Image but returns null when called for EditText. I have rechecked the ids multiple times and cross checked almost every little dependency, googled a lot but can't really find the solution, or the cause of the problem.
Bottom line is that the function findViewById is returning null to an object which clearly exists in the layout file with the same id used for the search.
Any help regarding this is appreciated.

You are initializing the profileNameTextBox at multiple places .
At one place you are using -
EditText t = (EditText) view.findViewById(R.id.profileNameTextBox);
to initialize profileNameTextBox.
Remove the initialization from saveContact(), onBackPressed() and from anywhere else.You should initialize it only once in loadViews(). That's it. And when you want to access it you can use nameView.

public void saveContact(View view){
EditText t = (EditText) view.findViewById(R.id.profileNameTextBox);
view is the button clicked. Something tells me that the text box you're looking for is not inside the button.
You created your view variables so you don't have to findViewById all the time. Use them:
EditText t = nameView;
