stuck at implementing button
<p>Im very new to java (mainly duel with embedded only)</p>

<p>Im writing a simple android program that passes a value of editText input to another editText by a click of a button. However every-time I hit the button my program crashes. would like anybody comments :)</p>

<p>This is my main:</p>

<pre><code>package Mushroom.Pickers.Note;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
//import android.widget.Button;
//import android.widget.TableLayout;

public class Mushy extends Activity {
//private TableLayout layout;
//private Button button;

/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);      
}   

public void Compute_data(View view) {//Function to perform on click
     //Perform calculation      
     int Hours;
     EditText start_time = (EditText)findViewById(R.id.editText26) ;
     Hours = Integer.parseInt(start_time.getText().toString());     

     EditText test_time = (EditText)findViewById(R.id.editText43);
     test_time.setText(Hours);

 }  
}
</code></pre>

<p>and in my xml:</p>

<pre><code>&lt;Button
        android:id="@+id/Button1"
        android:layout_width="134px"
        android:layout_height="wrap_content"
        android:gravity="center_vertical|center_horizontal"
        android:textSize="15sp"
        android:text="Calculate"
        android:onClick="Compute_data" 
        android:textColor="#1e90ff" /&gt;
&lt;/TableRow&gt;
&lt;EditText
        android:id="@+id/editText26"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical|center_horizontal"
        android:inputType="number"
        android:width="350px" /&gt;

&lt;EditText
        android:id="@+id/editText43"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical|center_horizontal"
        android:inputType="number"
        android:width="350px" /&gt;
</code></pre>

<p>The layout appears fine, just the matter of crashing when the button is clicked :(</p>

<p>P/S: here is the logcat:</p>
