One layout works but other doesnt

One layout works but other doesnt - android

everyone. I was creating a simple app for fun and came up with this problem. Basically, I checked everything and found some problem with the layouts. I am using navigation and from navigation, it takes the user to 4 different parts. Everything works except for the last part, the button is not taking me to anywhere.

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ScrollView
android:id="#+id/scrollSyllabus"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="UselessParent">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/chapone"
android:layout_width="340sp"
android:layout_height="70sp"
android:layout_gravity="center"
android:layout_marginLeft="55sp"
android:layout_marginTop="50sp"
android:background="#drawable/roundshapebtn"

android:text="#string/stoichometric_relations1"
android:textColor="#000000"
tools:ignore="RtlHardcoded" />
</RelativeLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>
Then my class for syllabus is for layout is:
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Chapter1 extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup
container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.chapteronesyll,container,false);
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
getActivity().setTitle("Stoichometric Relations");
}
}
With this class i use this layout to show:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="#+id/button2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="one" />
</LinearLayout>
Now for this button i havent put any onclick so i just want this button to be displayed in screen and thats it. I tried some other layouts in my activity and some of them worked perfectly but some didnt i tried to delete and add again but this didnt work it still didnt print anything on the screen. Any help would be appreciated.

Using AndroidStudio emulation On_Click Events within fragments firing when using tab and enter key but not mouse click

I have a problem within my code that seems to me as it is working but only in the given situation where On_Click Events within fragments are firing when using tab and enter key but not mouse click. I am using the emulator through android studio SDK23 for the emulater. When I test it on my phone sdk26 it does not allow the tap to click anything within the fragment.

Ultimately I fixed my own problem. Which was started by choosing Navigation Activity when first starting my project.
I removed
<include layout="#layout/nav_menu_main" />
from my activity_main.xml then restructured it whith the xml from nav_menu_main, using DrawerLayout as the Parent and CoordinatorLayout from activity_main.xml as the child.
I consulted this stack Overflow which lead me to my fix.

Unable to Get Navigation Drawer Items to Display Items Correctly

I have got a working Navigation drawer in a blank project, however whenever I try to implement the navigation drawer in to an existing project, it doesn't seem to be working properly.
The navigation drawer displays fine, however, when items inside are selected, it doesn't seem to redirect to the fragment selected.
I have tried using many resources, however, I am still unable to progress.
Thanks in advance.
Here is my code below:

How to set URL image properly in Android?

I am new to android, I am trying to open URL image on my main screen. My problem is that I am using navigation drawer also on my main page. Everything works fine only my main image which is coming from database is going slightly upwards, whereas the example which I copied in that the image is looking perfectly.
I don't know why my image is going upwards. The image should render like this :

I tried doing debugging but then also no use, it's so weird problem.

The problem occur for main_content xml . your image is cut off when you use it in you main_activity xml . Use this trick it will work . Simple put margin above your main_content xml

You have to include a custom action bar in your layout.
Please follow this link. It is explained very nicely with the code snaps and in depth. :)

In MainAcitivity you should extends Activity no an AppCompatActivity. AppCompatActivity show a bar

Text Visible in other Activities,

i just needed some quick help. I got a nav drawer setup, and i use activity main as my welcome screen, so I put a text box on the activity_main, but the problem is that when I chose other nav drawer pages, i see the text box from the activity main.
What one of my activity pages should look like: http://puu.sh/nQFkc/1ed83811cc.png
What it ends up looking like: http://puu.sh/nQF93/785c9eee45.png

The issue is with your layout.
Two approaches to fix your problem -
Whenever you instantiate any fragment by selecting any option from the navigation drawer, you can set ScrollView (containing the welcome text) visibility to GONE.
Scrollview scrollView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
scrollView = (ScrollView) findViewById(R.id.scrollView);
}
private void selectItem(int position) {
scrollView.setVisibility(View.GONE);
....
}
Create a one more fragment with the layout where you only show your welcome text and launch this fragment in onCreate() of your activity. So this will show the welcome text when user starts your app. and when user selects any item from Navdrawer, you can launch another fragment of your choice. But for this you should remove welcome text from activity layout xml.

/**

public class first extends Fragment {

Can you make it something like when you click btn1 it goes to fragmentOne and when click btn2 it goes to fragmentTwo an if-else statement?
What do I put in here?

You can use OnfragmentInteractionListener for this. It is a interface that your activity should implement. You can call the methods from your fragments and it will be like it is calling a method from the activity.
In the following example, first fragment has a button which when clicked calls the method changeFragment(2) and similarly the second fragment calls method changeFragment(1). This method is implemented in the main activity and through if .. else it figures out which fragment to replace.
OnFragmentInteractionListener.java
public interface OnFragmentInteractionListener {
public void changeFragment(int id);
}
FragmentA:
public class first extends Fragment {
private OnFragmentInteractionListener mListener;
public first() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_first, container, false);
Button btn = (Button) view.findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mListener.changeFragment(2);
}
});
return view;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mListener = (OnFragmentInteractionListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnFragmentInteractionListener");
}
}
#Override
public void onDetach() {
super.onDetach();
mListener = null;
}
}
FragmentB:
public class first extends Fragment {
private OnFragmentInteractionListener mListener;
public first() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_first, container, false);
Button btn = (Button) view.findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mListener.changeFragment(1);
}
});
return view;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mListener = (OnFragmentInteractionListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnFragmentInteractionListener");
}
}
#Override
public void onDetach() {
super.onDetach();
mListener = null;
}
}
MainActivity:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener, OnFragmentInteractionListener {
//Rest of the code
#Override
public void changeFragment(int id){
if (id == 1) {
fragment = new first();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.mainFrame, fragment);
ft.commit();
}
else if (id == 2) {
fragment = new second();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.mainFrame, fragment);
ft.commit();
}
}
}
Hope it helps!!
