Any help would be greatly appreciated! :)

You are calling an EditText that you don't have.
Either in your XML change your TextView to an EditText
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text"
android:id="#+id/button0"
android:layout_alignParentTop="true"
android:layout_alignLeft="#+id/button2"
android:layout_alignStart="#+id/button2" />
OR Change
private EditText Scr;
To
private TextView Scr;
And
Scr = (EditText) findViewById(R.id.button0);
To
Scr = (TextView) findViewById(R.id.button0);

How to disable interaction between buttons of the same layout?

I have two sets of layouts, populated with buttons. Is there a way to disable any interaction between buttons of the same layout? I just need nothing to happen when I click one button and then the other from the same layout. I tagged each button with " and ", for buttons that belongs to upper and lower layouts. I have 5 of each kind.
I have some interaction beetwen buttons of oposite layouts and that's working fine (actually interaction works fine between any two given buttons and that's bad), but I don't want that interaction between buttons of the same layout.
Here's my game class, not all of it, just important parts. Also, I've removed code for rest of the buttons, only left for 4 buttons, 2 for each layout, to save some space here. I import some text from sqlite database, and randomly set it to my buttons.
final OnClickListener clickListener = new OnClickListener() {
private Button buttonClicked;
public void onClick(View v) {
Button button = (Button) v;
button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x003333));
if (buttonClicked == null) {
// first button is clicked
buttonClicked = button;
} else {
// second button is clicked
if (buttonClicked.getTag().equals(button.getTag())) {
button.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x66FF33));
buttonClicked.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0x66FF33));
buttonClicked.setEnabled(false);
button.setEnabled(false);
} else {
buttonClicked.setEnabled(false);
buttonClicked.setTextColor(Color.GRAY);
buttonClicked.getBackground().setColorFilter(new LightingColorFilter(0xFFFFFFFF, 0xFFCC99));
button.getBackground().clearColorFilter();
}
buttonClicked = null;
}
};

You can use the getParent method and compare the parents of both views. If the parent is the same, then the buttons are in the same layout and nothing should happen.
Change your else:
} else {
// second button is clicked
... to an else if:
// only do stuff if buttons are in different layouts
} else if (button.getParent () != buttonClicked.getParent()) {
// second button is clicked

How do you pass data from FragmentA to hostActivity then update fragmentB

I have three fragments, Player1Tun, Player2Turn and TicTacToeLayout. Player1Turn and Player2Turn are inner-switching every time a player makes a move and TicTacToeLayout contains the tic tac toe table which update everytime the fragments switches. What I'm trying to do is to send the data from either player fragments to the host activity (while the program is still running) and then from there, I'll update the table in the TicTacToeLayout. Any ideas or method I can do it?
Player1:
package As2.packageTK;
//import android.app.Activity;
import java.util.ArrayList;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class PlayerTurn2 extends Fragment{
TextView p2Name;
TextView p2Icon;
Button doneP2;
Button resetP2;
EditText row;
EditText column;
TicTacToeLayout myObject2 = new TicTacToeLayout();
ArrayList<String> player2;
Bundle extras = new Bundle();
int turn = 2;
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.playerturn2, container, false);
return view;
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
extras = getArguments();
player2 = new ArrayList<String>(extras.getStringArrayList("player2"));
//Toast.makeText(getActivity(), player2.get(0), Toast.LENGTH_LONG).show();
//Toast.makeText(getActivity(), player2.get(1), Toast.LENGTH_LONG).show();
p2Name = (TextView) getActivity().findViewById(R.id.p2NameInfo);
p2Icon = (TextView) getActivity().findViewById(R.id.p2IconInfo);
row = (EditText) getActivity().findViewById(R.id.rowP2);
column = (EditText) getActivity().findViewById(R.id.columnP2);
doneP2 = (Button) getActivity().findViewById(R.id.doneP2);
//resetP2 = (Button) getActivity().findViewById(R.id.resetP2);
setPlayer(); //sets all the information of player 2, name, icon, image, etc
doneP2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
callPlayer1Fragment(); //switches with first player
}
});
}
public void callPlayer1Fragment()
{
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
Fragment Player1Frag = new PlayerTurn1();
Player1Frag.setArguments(extras);
ft.replace(R.id.fragment_container, Player1Frag);
ft.commit();
}
public boolean checkField()
{
if(row == null || column == null)
{
Toast.makeText(getActivity(), "Please input the row or column!", Toast.LENGTH_LONG).show();
return false;
}
else
return true;
}
public void setPlayer()
{
String name = player2.get(0);
if(!name.equals(""))
p2Name.setText("Player Name: " + name);
else
p2Name.setText("");
String icon = player2.get(1);
if(!icon.equals(""))
p2Icon.setText("Player Icon: " + icon);
else
p2Icon.setText("");
}
}
player 2 fragment is exactly the same code so I won't bother adding it.
TicTacToeLayout fragment class:
public class TicTacToeLayout extends Fragment {
TextView image1, image2, image3, image4, image5, image6, image7, image8, image9;
TextView[][] images;
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.tictactoe_layout, container, false);
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
image1 = (TextView) getActivity().findViewById(R.id.Image1);
image2 = (TextView) getActivity().findViewById(R.id.Image2);
image3 = (TextView) getActivity().findViewById(R.id.Image3);
image4 = (TextView) getActivity().findViewById(R.id.Image4);
image5 = (TextView) getActivity().findViewById(R.id.Image5);
image6 = (TextView) getActivity().findViewById(R.id.Image6);
image7 = (TextView) getActivity().findViewById(R.id.Image7);
image8 = (TextView) getActivity().findViewById(R.id.Image8);
image9 = (TextView) getActivity().findViewById(R.id.Image9);
images = new TextView[][]{ {image1, image2, image3},
{image4, image5, image6},
{image7, image8, image9} };
toast();
}
public void toast()
{
Toast.makeText(getActivity(), images[0][0].getText().toString(), Toast.LENGTH_LONG).show();
Toast.makeText(getActivity(), images[0][1].getText().toString(), Toast.LENGTH_LONG).show();
Toast.makeText(getActivity(), images[0][2].getText().toString(), Toast.LENGTH_LONG).show();
Toast.makeText(getActivity(), images[1][0].getText().toString(), Toast.LENGTH_LONG).show();
}
public void play(int row, int column, String icon)
{
images[row-1][column-1].setText(icon);
}
}

My friend did the same but with a implementing an interface he created in the fragments and having the main activity implement the interface. With that, he used a method to pass datas. Maybe it's not clear but if you know what I'm trying to say then you could clear it out for all of us :)

your friend is right, communicating with other fragments is nicely explained in the docs:

Clickable TableRow on Android

and here is my java code:
package com.coreservlets.widgets;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TableRow;
import com.welly.keychords.R;
public class keya extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.keya);
}
}
what i want to happen is that imageview1 will display a different image depending on what row is clicked. Any help would be greatly appreciated
As sam suggested i have ammended my code to this:
public class keya extends Activity {
ImageView imagev = (ImageView) findViewById(R.id.imageView1);
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.keya);
}
public void rowClick(View view) {
switch(view.getId()) {
case R.id.one:
// Load image from Drawable folder
imagev.setImageResource(R.drawable.android_normal); // example file for now
break;
}
}
}
but now i have a null pointer exception on running that class. all compiles fine though

Simply give each TableRow element a unique id and define an onClick method:
<TableRow
android:id="#+id/one"
android:onClick="rowClick">
Add a class variable imageView that references the ImageView in your layout. Then load the image:
public void rowClick(View view) {
switch(view.getId()) {
case R.id.one:
// Load image from Drawable folder
imageView.setImageResource(R.id.imageOne);
break;
}
}
Understand that any elements inside a TableRow with their own onClick method will call its own method. For instance the TextView with android:onClick="Achord" will call Achord() not rowClick().
Addition
You need to call findViewById() after declaring your layout with setContentView() in onCreate().
ImageView imagev;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.keya);
imagev = (ImageView) findViewById(R.id.imageView1);
}

Give each row an ID, then you can assign a listener to each one in your code:
TableRow row = (TableRow)findViewById( R.id.row1 );
row.setOnClickListener( new OnClickListener() {
#Override
public void onClick( View v ) {
//Do Stuff
}
} );

You need to call setOnClickListener() for each of your TableRow objects so that framework knows what to do when a row is clicked. In addition your Activity should implement View.OnClickListener() so that you can control what happens when a row gets clicked. Right now you aren't doing anything when the View gets clicked; at least according to your code you aren't registering a callback on any of the Views' onClickListeners

Assign id to Tablerow just like row1

Call it in activity like this.
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TableRow;
import com.welly.keychords.R;
public class keya extends Activity {
TableRow row1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.keya);
row1 = (TableRow) findViewById(R.id.row1);
row1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Log.e("Click ", "Row 1");
}
});
}
}

i got it working by declaring the imageview variable within the public void rowclick

Assign an id to Tablerow in xml layout file:
<TableRow
android:id="#+id/rowL1"
...
</TableRow>
Add the following in your java file:
private TableRow rowL1;
//In onCreateView...
rowL1 = (TableRow) rootView.findViewById(R.id.rowL1);
rowL1.setOnClickListener(v -> {
//Your code here...
});
