这是我的代码.它很简单但是当我点击按钮"button1"时,没有任何反应.我做错了什么？

public class TestTab extends Activity {

    Button button1;
        Intent i;


    @Override

    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        button1 = (Button) findViewById(R.id.btnScore);
        button1.setOnClickListener(new View.OnClickListener() {


            @Override
            public void onClick(View v) {

                Toast.makeText(getApplicationContext(), "On Click Event", 5000).show();

                //i = new Intent(TestTab.this, AndroidTab.class);
                //startActivity(i);

            }

        });
   }}

第二 -

package com.example.picturegame2;

import android.app.TabActivity;


public class AndroidTab extends TabActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tabzz);

        TabHost tabHost = getTabHost(); …
