Android: Button.setOnClickListener makes error during runtime
<p>I'm making a very simple application which has to perform an action when the user clicks a button .I tried to do this with a OnClickListener but this is causing the program to stop during runtime . I have looked for different solutions but nothing could help me .
I found that the problem is situated at the line where I placed : Button.setOnClickListener</p>

<pre><code>public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(0x7f030000);

    Button b   = (Button) findViewById (0x7f05000a) ; 
    b.setOnClickListener((android.view.View.OnClickListener) buttonL) ;



}
private OnClickListener buttonL  = new OnClickListener ( ) {

    @Override
    public void onClick(DialogInterface arg0, int arg1) {
//perform action}   
};
</code></pre>

<p>The error given by Logcat :</p>
