Question

I have the following code which worked before. Then after I started working on another activity (implementing ListActivity and providing a custom view per row by extending an ArrayAdapter), I start getting the RuntimeException:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.ezport/com.ezport.EzportActivity}: java.lang.RuntimeException: Don't call setOnClickListener for an AdapterView. You probably want setOnItemClickListener instead

Here is the code

package com.ezport;

import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;    
public class EzportActivity extends Activity implements OnClickListener {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        View view_orders_button = findViewById(R.id.view_orders_button);
        view_orders_button.setOnClickListener(this);
        View submit_invoice_button = findViewById(R.id.submit_invoice_button);
        submit_invoice_button.setOnClickListener(this);
        View help_button = findViewById(R.id.help_button);
        help_button.setOnClickListener(this);
    }

    public void onClick(View view) {
        switch (view.getId()) {
        case R.id.view_orders_button:
            Intent order_intent = new Intent(this, OrderActivity.class);
            startActivity(order_intent);
            break;
        case R.id.submit_invoice_button:
            //Intent i = new Intent(this, )
            break;
        case R.id.help_button:
            Intent help_intent = new Intent(this, HelpActivity.class);
            startActivity(help_intent);
            break;
        }
    }
}

What did I do wrong?

Answer 1

Try this:

Button button1 = (Button)findViewById(R.id.button);
button1.setOnClickListener(this);

This works for me and it might fix your problem, it looks like good code i wouldn’t see why else it wouldnt be working.
