TextView Array not working?

Question

here is my code:

public class fm_weapons extends Activity implements OnClickListener {

ImageView display;
TextView dis;
TextView[] textViewArray;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.weapons);

    display = (ImageView) findViewById(R.id.empty);
    dis = (TextView) findViewById(R.id.emptyText);
    textViewArray= new TextView[] {(TextView)findViewById(R.id.k_k),(TextView)findViewById(R.id.s_s), 
            (TextView)findViewById(R.id.h_d) };

     ......
    kk_btn.setOnClickListener(this);
    ss_btn.setOnClickListener(this);
    hd_btn.setOnClickListener(this);
 }
    @Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()){
    case R.id.kk_btn:
        display.setImageResource(R.drawable.king_k);
        dis.setText(textViewArray[0].getText());
        break;
    case R.id.ss_btn:
        display.setImageResource(R.drawable.start_s);
        dis.setText(textViewArray[1].getText());
        break;
    case R.id.hd_btn:
        display.setImageResource(R.drawable.hidden_d);
        dis.setText(textViewArray[2].getText());
        break;

}

what I am trying to do is, as you can see I have 3 buttons and I want when someone clicks one of them to represent the textview assigned to them (check the image for a better understanding). My TextViews are written in an other xml to in the main xml that I am working on because I don't any of them to appear in the main xml except if they are called.

Using the code above gives me this error in the logcat:

this is line #153:

dis.setText(textViewArray[0].getText());

the xml of the textview:

<TextView 
    android:id="@+id/k_k"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textSize="15sp"
    android:textColor="@android:color/holo_blue_bright"
    android:text="Increases defense"/>

<TextView 
    android:id="@+id/s_s"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textSize="15sp"
    android:textColor="@android:color/holo_blue_bright"
    android:text="Increases strenght." />

<TextView 
    android:id="@+id/h_d"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textSize="15sp"
    android:textColor="@android:color/holo_blue_bright"
    android:text="Restores MP." />

Any Idea how to fix this, that would be great if you are able to help me, Thanks

If your text views are on different layout file, then you need to get them using:

LayoutInflater inflater 
                 = (LayoutInflater)getBaseContext()
                  .getSystemService(LAYOUT_INFLATER_SERVICE);
View v = inflater.inflate(R.layout.<yourtextviewlayout>, null); 
TextView t = (TextView)v.findViewById(R.id.k_k); 

.... get other textviews too and add them to an array

or keep them in same layout as your buttons and make them visible on button click:

textView.setVisibility(View.VISIBLE)

by default have them invisible by setting it in layout xml using:

android:visibility="false"
