Button onClick error…Could not find a method

Question

I can\'t seem to start a new Activity from my Button, I have searched here for answers, but can\'t seem to resolve the problem. I hope someone has

Answer 1

First make a reference to your button

    search = (Button) findViewById(R.id.btnStartSearch);

Then implement the onClick listner for the button as below

        search.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

             Intent openSearchIntent = new Intent(MainActivity.this, StartSearch.class);
             startActivity(openSearchIntent)
        }
    });

Make sure you remove this line from your XML file

 android:onClick="openSearch"

Answer 2

The problem is in your method signature

public void openSearch(){

it should have one, and only one param, which is a View.

Change it to

public void openSearch(View v){

v obviously can be anything you want it to be but you should make it something meaningful like v, view, etc...

From the Docs

In order for this to work, the method must be public and accept a View as its only parameter.
