Button is not clickable or focusable
<p>I have created a button in my screen's XML like this:</p>

<p>
  </p>

<pre><code>   &lt;Button android:text="Lets Get Started"        

          android:background="@drawable/btnbg"  
          android:id="@+id/btn_nav_let_strtd"android:layout_width="wrap_content" 
           android:layout_height="35px" 
           android:textColor="#FFFFFF"
           android:layout_alignParentLeft="true"
           android:drawableRight="@drawable/arrow"
           android:drawableLeft="@drawable/nav_getstart"&gt;
           &lt;/Button&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>set click listenrss</p>

<pre><code>private LinearLayout ll_get_started;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation);
btn_nav_lets_get_strtd = (Button) findViewById(R.id.btn_nav_let_strtd); 

btn_nav_lets_get_strtd.setClickable(true);

}
private void setOnclickListeners() {
btn_nav_lets_get_strtd.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
    System.out.println("clicked");
    Toast.makeText(NavigationScreen.this, "fgd",Toast.LENGTH_SHORT).show();
    }
});
</code></pre>

<p>But when I try to click this button, it is neither clickable nor focusable. How do I set it as clickable?</p>

<p>I am now using a statelist drawable, but it sets the background when focused or clicked. I want to set a permanent background to this button.</p>

<p>And the drawable is not a bitmap, it is a statlist drawable btnbg. XML is below:</p>

<pre><code>    &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"
    android:constantSize="true"
    android:dither="true"
    android:variablePadding="true" &gt;
    &lt;item
    android:drawable="@drawable/nav_blue_bar"
    android:state_pressed="true"
    /&gt;
</code></pre>
