This question already has an answer here: Button is not clickable or focusable (1 answer) Closed 9 years ago.

I have created a button in my screen's xml like this

 <?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/bg">


       <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开发者_StackOverflow中文版_alignParentLeft="true"
               android:drawableRight="@drawable/arrow"
               android:drawableLeft="@drawable/nav_getstart">
               </Button>

set click listenrss

public class NavigationScreen extends Activity implements OnClickListener{ private Button btn_nav_lets_get_strtd;

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();
         }
     });



}

}

look at your Code , you didn't call the method setOnClickListeners() in your method onCreate() !! ,

to fixe your problem , you should call your method like this :

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);//here you don't need to call this method because the button is clickable by default

//call your method setOnClickListeners() here 
setOnClickListeners();




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