package zhang.choiceMenu;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class choice extends Activity {
	private Button button;
	
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        button=(Button)findViewById(R.id.button1);
        
        button.setOnClickListener(new OnClickListener(){

			@Override
			public void onClick(View arg0) {
				
				new AlertDialog.Builder(choice.this)
				.setTitle("choice")
				.setItems(R.array.str_body, new DialogInterface.OnClickListener() {
					
					@Override
					public void onClick(DialogInterface arg0, int arg1) {
						// TODO Auto-generated method stub
						
						String[] aryshop=getResources().getStringArray(R.array.str_body);
						new AlertDialog.Builder(choice.this)
						.setMessage(aryshop[arg1])
						.setNegativeButton("ok", new DialogInterface.OnClickListener() {
							
							@Override
							public void onClick(DialogInterface arg0, int arg1) {
								// TODO Auto-generated method stub

							}
						}).show();
					}
				}).show();
