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

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

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;

NavigationDrawer blocks/stops other buttons on the activity

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

</android.support.v4.widget.DrawerLayout>

Same Fragment Should Appear one below another according to the Number Selected in Spinner. HOW?

I have a Small Fragment with three EditText and i have a Spinner with 1,2,3 as options in It.
What i want to do is that, when i select '1' from the Spinner, i want my fragment to appear below the spinner in same Activity.
And when i select '2' in Spinner, the same Fragment Should Appear Twice one below another in the same Activity and similarly for when i select '3' from Spinner.

LET ME KNOW IF I SHOULD ATTACH SOMETHING ELSE
I TRIED TO USE WHILE LOOP BUT THE APP CRASHES. PLEASE HELP
THANK YOU
I tried it with this Layout Inflater Code.
FrameLayout item = (FrameLayout) findViewById(R.id.FM1);
View child = getLayoutInflater().inflate(R.layout.fragment_bookentry, null);
item.addView(child);
It adds the Fragment once when i open the Activity.
But when i select 2 from the spinner, Nothing Happens.
I am using Switch Case for this Purpose
switch (i) {
case 0:
FrameLayout item = (FrameLayout) findViewById(R.id.FM1);
View child = getLayoutInflater().inflate(R.layout.fragment_bookentry, null);
item.addView(child);
break;
case 1:
FrameLayout item2 = (FrameLayout) findViewById(R.id.FM1);
View child2 = getLayoutInflater().inflate(R.layout.fragment_bookentry, null);
item2.addView(child2);
FrameLayout item3 = (FrameLayout) findViewById(R.id.FM1);
View child3 = getLayoutInflater().inflate(R.layout.fragment_bookentry, null);
item3.addView(child3);
break;
case 2:
FrameLayout item4 = (FrameLayout) findViewById(R.id.FM1);
View child4 = getLayoutInflater().inflate(R.layout.fragment_bookentry, null);
item4.addView(child4);
FrameLayout item5 = (FrameLayout) findViewById(R.id.FM1);
View child5 = getLayoutInflater().inflate(R.layout.fragment_bookentry, null);
item5.addView(child5);
FrameLayout item6 = (FrameLayout) findViewById(R.id.FM1);
View child6 = getLayoutInflater().inflate(R.layout.fragment_bookentry, null);
item6.addView(child6);
break;
}

Make the FrameLayout a class object, and initialize it using (FrameLayout) findViewById(R.id.FM1); only once, outside the switch statement.
In each of your case blocks, add this piece of code in the beginning:
if(item.getChildCount()>0){
item.removeAllViews();
}
EDIT: Your spinner's onItemSelected would be something like:
#Override
public void onItemSelected(AdapterView<?> parent, View view, int i, long id) {
item.removeAllViews();
for (int j=0;j<=i;j++){
View v = getLayoutInflater().inflate(R.layout.fragmentXML, null);
item.addView(v);
}
}

How to add strings from editText to a listView

I have a MainActivity with a ListView and an add Button. When the user clicks the add Button it takes you to another activity the CreateActivity for you to enter in data or strings into the editText boxes. After that you click the create Button and it adds the strings to the ListView it shows up, but every time I try to add another item to the ListView it just overrides the first item and doesn't add on to the ListView.

every time you restart the MainActivity, it is be created, the onCreate method was executed .one method you can use the comment method：use startactivityforResult;
you can read this question how to manage startactivityforResult.the second method is to set MainActivity model to SingleInstance.

You are starting MainActivity over and over again, clearing all data previously loaded.
Try this solution
Main activity:
package com.example.brian.inventoryapp;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import static android.R.layout.simple_list_item_1;
public class MainActivity extends AppCompatActivity {
public static final int CREATE_REQUEST = 1;
private Button addButton;
private ListView itemListView;
private ArrayList<String> arrayList;
private ArrayAdapter<String> arrayAdapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
itemListView = (ListView) findViewById(R.id.itemListView);
addButton = (Button) findViewById(R.id.addButton);
arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, arrayList);
itemListView.setAdapter(arrayAdapter);
addButton = (Button) findViewById(R.id.addButton);
addButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, CreateActivity.class);
startActivityForResult(intent, CREATE_REQUEST);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CREATE_REQUEST) {
if (resultCode == RESULT_OK) {
String item = data.getStringExtra("data");
arrayList.add(item);
arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, arrayList);
itemListView.setAdapter(arrayAdapter);
}
}
}
}
In your CreateActivity change createButton listener to this one:
createButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
String item = "";
item = editTextItem.getText().toString().trim() +
editTextModel.getText().toString().trim() +
editTextSerial.getText().toString().trim() +
editTextID.getText().toString().trim();
Intent intent = new Intent();
intent.putExtra("data", item);
setResult(RESULT_OK, intent);
finish();
}
});

Yes it will assume as if the MainActivity is started for the first time so you should use startActivityForResult() method instead of startActivity().This will continue your MainActivity and do not override your list View.

i get the Error: java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification

I don't know what is wrong with this code. I am trying to make a to do list app. I am new to Android and Java programming so please don't get mad if this is a simple errror.It gives me the error in the title.
Here is my XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

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">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/lvItems"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add"
android:id="#+id/button"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:onClick="onAddItem"/>
<EditText
android:layout_width="wrap_content"

android:hint="Enter a new item"
android:layout_alignParentStart="true"
android:layout_alignTop="#+id/button"
android:layout_toStartOf="#+id/button" />
</RelativeLayout>
Here is my Java:
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import java.util.ArrayList;
public class MainActivity extends Activity {
private ArrayList<String> items;
private ArrayAdapter<String> itemsAdapter;
private ListView lvItems;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//EditText
final EditText etTask = (EditText) findViewById(R.id.etNewItem);
final String Task = etTask.getText().toString();
lvItems = (ListView) findViewById(R.id.lvItems);
items = new ArrayList<String>();
itemsAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, items);
lvItems.setAdapter(itemsAdapter);
items.add("First Item");
items.add("Second Item");
//Button
Button btn = (Button) findViewById(R.id.button);
//Adding a Task
//OnClickListeners
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
items.add(etTask.getText().toString());
etTask.setText("");
}
});
}
}

Since you made a change to adapter after ListView was populated, Listview must be informed to repopulate the views with new values by calling notifydatasetchanged() on your adapter ie,
items.add(etTask.getText().toString());
((ArrayAdapter)lvItems.getAdapter()).notifydatasetchanged();
etTask.setText("");

problems with activity layout when back button is pressed

I have this activity with EditViews and button. When the button is pressed I move on to a new activity. the problem is when the back button is pressed. The EditViews are not visible. What is expected is that the views and the text that was entered are visible. Also The buttons that appear are from the second activity and not the first.

You are changing first Activity's View before calling StartActivity.
Remove this in MainActivity1Activity:
setContentView(R.layout.activity_main_activity11);
Furthermore, if you want to keep view state in MainActivity1Activity don't start it again. Just call finish() in second activity.
