意图活动没有解雇？

Question

我正在做一个从一个页面移动到另一个页面的基本活动。一切都很完美，直到我深入了解应用程序两页。我为每个页面类使用了相同的确切代码，将活动放在清单中并确保所有单词拼写正确等等，但当我尝试深入三页时，意图没有做任何事情。根本没有日志中的错误消息。当我单击第三页上的按钮时，它只是变为蓝色但不会像前一页那样移动到下一页。这是我的代码：

从第1页到第3页：

第1页：

    public class MainActivity extends ActionBarActivity {

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

public void addListenerOnButton() {

    final Context context = this;

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

    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(context, MainMenu.class);
                        startActivity(intent);   

        }

    });

    }
   }

第2页：有更多按钮......

   public class MainMenu extends ActionBarActivity {

Button button;
Button button2;
Button button3;
Button button4;
Button button5;

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

public void addListenerOnButton() {

    final Context context = this;

    button = (Button) findViewById(R.id.button1);
    button2 = (Button) findViewById(R.id.button2);
    button3 = (Button) findViewById(R.id.button3);
    button4 = (Button) findViewById(R.id.button4);
    button5 = (Button) findViewById(R.id.button5);

    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(context, OneMain.class);
                        startActivity(intent);   
        }       
    });

    button2.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(context, TwoMain.class);
                        startActivity(intent);   
        }       
    });

    button3.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(context, ThreeMain.class);
                        startActivity(intent);   
        }       
    });

    button4.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(context, FourMain.class);
                        startActivity(intent);   
        }       
    });

    button5.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(context, FiveMain.class);
                        startActivity(intent);   
        }       
    });

          }
         }

第3页：

   public class OneMain extends ActionBarActivity {

Button button;


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

     }

public void addListenerOnButton() {

    final Context context = this;



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


    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent intent = new Intent(context, Alphabet.class);
                        startActivity(intent);   
        }       
    });



           }


          } 

我也确保放入所有进口货物。有人帮忙。我被卡住了:(。

这是清单xml：

       <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.juwar74.alarabic"

android:versionName="1.0" >

          android:label="@string/app_name"

     <activity

    <activity

    <activity

    <activity

        android:name=".FourMain" >
    </activity>

    <activity
        android:label="@string/app_name"
        android:name=".FiveMain" >

    <activity
       android:label="@string/app_name"
       android:name=".OneVoc" >
    </activity>
</application>

</manifest>

这是Alphabet.class的代码

  import android.os.Bundle;
  import android.support.v7.app.ActionBarActivity;

  public class Alphabet extends ActionBarActivity {

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

     }

}
