Button OnClickListener stopped unexpectedly

Question

I am having stopped unexpectedly problem when I click on the "Insert" and "Update". The first button MovieList works fine.I can't find the error that caused it to stop.

Here is my codes.

MainActivity.java:

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        findViewById(R.id.MovieList).setOnClickListener(click);
        findViewById(R.id.Insert).setOnClickListener(click);
        findViewById(R.id.Update).setOnClickListener(click);
        findViewById(R.id.Delete).setOnClickListener(click);

    }
Button.OnClickListener click = new View.OnClickListener() {

        @Override
        public void onClick(View l) {
            // TODO Auto-generated method stub
            switch(l.getId()){
            case R.id.MovieList:
                Intent s = new Intent(MainActivity.this, list.class);
                startActivity(s);
                break;

            case R.id.Insert:
                Intent i = new Intent(MainActivity.this, insert.class);
                startActivity(i);
                break;

            case R.id.Update:
                Intent u = new Intent(MainActivity.this, update.class);
                startActivity(u);
                break;

            case R.id.Delete:

                break;
            }
        }
    };

My insert class is empty and i just created an edittext to see if the page can be opened.

insert.java:

package com.example.project;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.EditText;

public class insert extends Activity{

    EditText insET;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.id.Insert);

        insET = (EditText) findViewById(R.id.insertET);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // TODO Auto-generated method stub
        return super.onCreateOptionsMenu(menu);
    }

}

LogCat:

setContentView(R.id.Insert); is the problem; you should be using a layout resource file, e.g.

setContentView(R.layout.insert_layout);

where insert_layout.xml is located in the res/layout resource folder and defines your activity's view hierarchy.
