EditText在ImageButton新聞上沒有改變？

-1

我對編碼非常陌生，所以可能會遇到各種各樣的問題，但經過一段時間的搜索之後，我找不到它有什麼問題，我沒有得到任何錯誤或崩潰，按鈕只是沒做什麼？EditText在ImageButton新聞上沒有改變？

目的是讓橙色箭頭增加和減1。在中間的數字

我不知道是什麼碼向你展示，所以這裏是最重要的：

我只是複製和粘貼你的代碼它的工作，因爲你想，但在這裏，我只使用你的活動和佈局（與刪除線工具：上下文=「。T3_TrampetFragment」）。在我的代碼中沒有添加片段（B'coz我沒有找到任何理由在代碼中使用片段）。因此，請檢查從代碼中刪除片段。 – Janak

在目前的形式下，有人回答你的問題將會非常困難。我們不知道你以前是否曾經工作過，但是也許你改變了一件事，並且按鈕停止工作。這是重要的信息。我認爲你最好的選擇是爲Android找到一些示例代碼，創建一個非常簡單的應用程序，例如一個按鈕更新一個計數器。運行該示例，然後進行小的更改。（例如兩個計數器，兩個按鈕）如果該更改不起作用，請向* that *問題尋求幫助。代碼將小得多，人們將更有可能回答。 – leoger

@Janak片段是爲了讓標籤在頂部工作，或者至少它認爲這是唯一的方法？ – Connor

創建T3_TrampetActivity這樣而從活動請致電您的片段：

public class T3_TrampetActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Fragment fragment = new T3_TrampetFragment(); 
     getSupportFragmentManager().beginTransaction() 
       .replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit(); 

    } 
}

創建activity_main.xml中爲這樣的：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"     
      android:id="@+id/fragment_frame"    
      android:layout_width="match_parent" 
      android:layout_height="match_parent" />
