Need help getting buttons to work
<p>I am trying to get my first button to update a display number in my view when clicked. This view will have several buttons and "outputs" displayed. After reading examples and Q's here, I finally put something together that runs, but my first button is still not working;</p>

<pre><code>   public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ship_layout);
        mSwitcher = (TextSwitcher) findViewById(R.id.eng_val);
        }

    private TextSwitcher mSwitcher;

        // Will be connected with the buttons via XML
        void onClick(View v){

            switch (v.getId()) {
            case R.id.engplus:
                engcounter++;
                updateCounter();
                break;
            case R.id.engneg:
                engcounter--;
                updateCounter();
                break;
            }
        }
    private void updateCounter() {
        mSwitcher.setText(String.valueOf(engcounter));
    }
</code></pre>

<p>The .xml for this button is;</p>

<pre><code>     &lt;TextSwitcher
    android:id="@+id/eng_val"
    android:visibility="visible"
    android:paddingTop="9px"
    android:paddingLeft="50px"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/build"
    android:layout_toRightOf="@+id/engeq"
    android:textColor="#DD00ff00"
    android:textSize="24sp"/&gt;       
</code></pre>

<p>This is within a Relative Layout that appears otherwise OK. When I had set the view to have a TextView with the number set as a string , the number displayed, but I could not figure out how to update the text with a numerical field. That may be my real problem.</p>

<p>I have gone through many examples generally referenced from the dev. site (UI, Common Tasks, various samples), and I am still not seeing the connection here...</p>

<p>Again, this is simply a try at getting variables to respond to buttons and update on the view.</p>

<p>So, a few Q's for anyone that can help;</p>

<p>1) Is there any easier way of doing this (ie. send numerical value to View) ?
2) Why isn't my TextSwitcher displaying the number?
3) Should I be using a TextSwitcher here?
4) Any examples of this you can point me to?</p>

<p>UPDATE!!!: Buttons with feedback are now working. Here is my fix, based on feedback, research and luck;</p>

<p>public class Myview extends Myapp implements ViewSwitcher.ViewFactory,
View.OnClickListener {</p>

<pre><code>public int engcounter = 1;
private TextSwitcher mSwitcher;

@Override
public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_layout);
        mSwitcher = (TextSwitcher) findViewById(R.id.eng_val);
        mSwitcher.setFactory(this);


    Button engp = (Button) findViewById(R.id.engplus);
    engp.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view){
        engcounter++;
        updateCounter();
        }
    });

    Button engn = (Button) findViewById(R.id.engneg);
    engn.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view){
        engcounter--;
        updateCounter();       
        }   
    });

   }
    private void updateCounter() {
        mSwitcher.setText(String.valueOf(engcounter));
    }
    public View makeView() {
        TextView t = new TextView(this);
        t.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL);
        t.setTextSize(36);
        return t;
    }
    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

}
</code></pre>

<p>Some of this appears unnecessary at the moment (ie. Gravity on makeView), but it works! And should work for the 10-20 buttons I want to do misc things with.</p>

<p>The key was getting listeners right, and the whole set-up for TextSwitcher was abit awkward...still learning.</p>

<p>Any other final comments welcomed!</p>

<p>UPDATE UPDATE!!
I found this also;</p>
