package com.format;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import android.view.View;
import android.view.View.OnClickListener;


public class Add extends Activity implements OnClickListener {
	 @Override
	    public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);
	        setContentView(R.layout.main2);
	        Button ba=(Button)findViewById(R.id.buttona);
	        Button bb=(Button)findViewById(R.id.buttonb);
	        ba.setOnClickListener(this);
	        bb.setOnClickListener(this);
	 }

	public void onClick(View v) {
		EditText eta=(EditText)findViewById(R.id.editTexta);
		EditText etb=(EditText)findViewById(R.id.editTextb);
		EditText etd=(EditText)findViewById(R.id.editTextd);
		String word=eta.getText().toString();
		String scramble = etb.getText().toString();
		WordData teaData = new WordData(this);
		String delete = etd.getText().toString();

		// TODO Auto-generated method stub
		switch(v.getId()){
		case R.id.buttona:teaData.insert(word,scramble); break;
		case R.id.buttonb:teaData.delete(delete);break;}
		
		
		}}

There is absolutely no problem with the button clicks here or the code, the problem might be with your WordData class

[ian myers]

found the problem. there was something wrong with the emulator, I made a new one and it works, but whenever it runs on the old one it just force closes weird

[zoheb hassan]

Yeah there are instances of even weirder behaviour
