    In xml,make sure you declared onClick in your Button attribute

    android:onClick="cli"

    Also, in onCreate, declare your Button id

    Button button = (Button) findViewById(R.id.button);

    Don’t use onClick on XML, as it’s buggy and may not work on all versions:

    Buttons onClick Force closes app on Android 4.1 device

    Better do it in code:

    findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
   public void onClick(View v) {
       // code here
   } 
});

    Don’t use onClick on XML.

    Use OnClickListeners. Here is the code:

    Button button = findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
   public void onClick(View v) {
       cli(v);
   } 
});

    The above code will help you with detecting clicks on the button. Prefer not using android:onClick in XML.
