第三個環節是行不通的

Question

我創建了一個按鈕，帶我到另一個網頁，並在其他頁面，還有一個按鈕，帶至另一個頁面，所以第1頁，第2頁，它不是和我一起工作的第3頁，檢查http://oi62.tinypic.com/2m7g4et.jpg當我點擊「魚指南」，它帶我到另一個具有另一個按鈕「魚」，當我在「魚」，點擊它不帶我去第3頁！

我做的第三頁，它運行但它是錯的..

MainActivity2.java

package com.d.di; 


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

public class MainActivity2 extends Activity { 

    Button fishlink; 

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

    public void addListenerOnButton() { 
     final Context context = this; 
     fishlink = (Button) findViewById(R.id.fish); 

     fishlink.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 

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

      } 

     }); 

    } 

} 

PageFish.java

package com.d.di; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.Button; 

public class PageFish extends Activity { 

    Button fishlink; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.fish); 
    } 
} 

幫助:)

編輯/它去「魚指南」，以「魚」當我點擊「魚」再次帶我到「魚」等，它不走第三頁！

PageThree.java

package com.d.di; 

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

public class PageThree extends Activity { 

    Button button3; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.fishguide); 
     addListenerOnButton(); 
    } 
    public void addListenerOnButton() { 
     final Context context = this; 

     button3 = (Button) findViewById(R.id.fish); 

     button3.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View arg0) { 

       Intent intent = new Intent(context, PageThree.class); 

       startActivity(intent); 

      } 

     }); 
} 
} 

Answer 1

您已經使用

setContentView(R.layout.fishguide); 

在PageThree.java

更改成你希望在形象，第三圖像顯示的XML。例如，third.xml

setContentView(R.layout.third); 

然後你就完成了。

Answer 2

注意：您一次又一次得到相同的佈局，因爲在PageThree.java中，您開始的目的是PageThree.java。相反，只需將其更改爲PageFish.java即可。

所以，當你在第二個佈局（PageThree.java），剛開始的第三輪廓（PageFish.java）按鈕點擊活動如下 -

PageThree.java

package com.d.di; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.Button; 

public class PageThree extends Activity { 

    Button button3; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.fishguide); 

    button3 = (Button) findViewById(R.id.fish); 

     button3.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View arg0) { 

       Intent intent = new Intent(PageThree.this, PageFish.class); 

       startActivity(intent); 

      } 

     }); 

    } 
}
