RuntimeException: Unable to start activity ComponentInfo: java.lang.NullPointerException Fatal exception - java

Hi i'm new to android programming and i'm having this issue where i'm sure that my code should work but doesn't.
This is my MainActivity.java:
package com.example.evo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageButton;
public class MainActivity extends Activity {
ImageButton imageButton2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.open);
imageButton2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), SecondScreenActivity.class);
}
} );
}
}
This is my SeconScreenActirity.java

public class SecondScreenActivity extends Activity {

I also updated my AndroidManifest.xml to add SeconScreenActivity.java
And i'm getting this
java.lang.RuntimeException: Unable to start activity
ComponentInfo java.lang.NullPointerException
errors please plase help!

You never initialize your imageButton element in your first activity.
So you get the NullPointerException when trying to assign to it the click listener.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.open);
//or whatever the id is for the image button in the open layout
imageButton2 = (ImageButton) findViewById(R.id.imageButton2);
imageButton2.setOnClickListener(new View.OnClickListener() {

You missed to take reference of ImageButton from open layout:
imageButton2 = (ImageButton) findViewById(R.id.<ImageButtonIdInOpenXml);

Just add below line
imageButton2 = (ImageButton)findViewById(R.id.imageButton1);
after
setContentView(R.layout.open);
Your are getting error because view ImageButton is not initialized

It doesn't send the data from Activity to Fragment

I have lots of layouts and activites and fragments. There are tabs in one activity called Hastane1 and it has four tabs in it. They don't have any problem but one of them has. I wanted to send a data from one Activity to a Fragment. They are seperate. Fragment is in Hastane1 activity but Haberlesme1 activity is in another place. It supposed to send the numbers which i entered in the activity called Haberlesme1 to the textView in the fragment called Hastane1Tab3Frag which is a tab of Hastane1.
The Android Studio itself doesn't have any errors but when i run the app on my phone, it stops when i pressed the button called "Gönder" (#id/button8).

This is me java class

import okhttp3.Response;
public class Chatting extends ListActivity {
EditText mess;
ImageButton send;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.yon);
mess = (EditText) findViewById(R.id.mess);
mess.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
}
}
});
}
}
I don't want the soft keyboard to push the header . it should push only the list view up.

Android Studio - App Crashes

How can I change or add more code to make this app to stop crashing? This activity is called "WhatBin", I simply wanted to make a button listen to when a person would click and change a text view. (VIEW PICTURES BELOW FOR MORE DETAILS.)

package com.example.tiffany.whatbin;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

import android.view.Menu;
import android.view.MenuItem;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import org.w3c.dom.Text;
public class WhatBin extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_what_bin);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final TextView txt_answer = (TextView) findViewById(R.id.txt_answer);
Button btn_go = (Button) findViewById(R.id.btn_go);
btn_go.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
txt_answer.setText("Marker - Recycle Bin");
}
});
};
}

UPDATE
You are currently using abc_dialog_material_background_dark as textcolor. As you can see in the source of this resource, it is basically a shape. And, shape cannot be used for textcolor.
In your XML file at line 17 you have used a color. That color is of wrong type. My guess, you have used a drawable instead of a color.
Post your activity_what_bin.xml for further explanation.

How to stop a textbox from scrolling in android

I am trying to create a View with an image and a list view in linear layout with vertical orientation and a EditText that should be on top all the times. I should be able to scroll the image and listview together, but not the EditText at the bottom.
I am somewhat new to android and sorry if i am not making any sense. ask me anything you need for additional info.
Here is my code..
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:singleLine="true"
android:text="Name"
android:textSize="14dp"
android:textStyle="bold" />
</LinearLayout>

</LinearLayout>
</ScrollView>
