項目在另一個佈局不響應用戶事件

Question

請看看下面的代碼

game_activity.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context=".Game" > 

    //Please note the GUI Has been removed 


     <include layout="@layout/common_status_bar"/> 


</RelativeLayout> 

Game.java

package game.games; 

import android.os.Bundle; 
import android.app.Activity; 
import android.content.Context; 
import android.content.Intent; 
import android.view.LayoutInflater; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.View.OnTouchListener; 
import android.widget.Button; 
import android.widget.ImageView; 
import android.widget.TextView; 

import java.util.ArrayList; 
import java.util.Collections; 

public class Game extends Activity { 


    private ImageView goToLanguageSelection; 
    private ImageView goToInternet; 
    private Button giveUp; 


    private LayoutInflater layoutInflater; 
    private View commonView; 


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

     layoutInflater= (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     commonView = layoutInflater.inflate(R.layout.common_status_bar, null); 

     //Intializing instance variables 
     goToLanguageSelection = (ImageView)commonView.findViewById(R.id.backToLanguageSelectionButton); 
     goToInternet = (ImageView)commonView.findViewById(R.id.internetButton); 
     giveUp = (Button)commonView.findViewById(R.id.giveUpButton); 

     flag = getIntent().getBooleanExtra("LANGUAGE", true); 

     //Add listeners 

     goToLanguageSelection.setOnClickListener(goToLanguageSelectionClicked); 



    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.game, menu); 
     return true; 
    } 








    //Will get activated when the ThunderBolt image is clicked 
    private OnClickListener goToLanguageSelectionClicked = new OnClickListener() 
    { 

     @Override 
     public void onClick(View v) 
     { 
      // TODO Auto-generated method stub 
      Intent intent = new Intent(getBaseContext(),LanguageSelector.class); 
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
      startActivity(intent); 

     } 

    }; 


} 

common_status_bar.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom="true" 
    android:background="#373734" 
    android:orientation="horizontal" > 



     <ImageView 
      android:id="@+id/backToLanguageSelectionButton" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:paddingBottom="5dp" 
      android:layout_marginLeft="10dp" 
      android:layout_marginRight="15dp" 
      android:paddingTop="5dp" 
      android:src="@drawable/thunderbolt" /> 

     <ImageView 
      android:id="@+id/internetButton" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:paddingBottom="5dp" 
      android:paddingTop="5dp" 
      android:src="@drawable/globe_small_2" /> 

     <ImageView 
      android:id="@+id/justForFun" 
      android:layout_width="0dp" 
      android:layout_height="wrap_content" 
      android:layout_weight="1" 
      android:paddingBottom="5dp" 
      android:paddingTop="5dp" /> 

     <Button 
      android:id="@+id/giveUpButton" 
      android:layout_width="wrap_content" 
      android:layout_height="match_parent" 
      android:layout_gravity="right" 
      android:paddingTop="5dp" 
      android:paddingBottom="5dp" 
      android:text="Button" /> 


</LinearLayout> 

在這裏，common_status_bar.xml是一個常見的佈局。我已通過<include layout="@layout/common_status_bar"/>將此佈局添加到game_activity.xml。

它顯示一切正常，沒有問題。但情況是我無法使它的任何元素工作。我已將OnClickListener附加到它的第一個元素goToLanguageSelection，但它沒有響應Click。我通過將click事件添加到所有其他按鈕，圖像（一次一個）來測試這一點，並得到了相同的結果。它沒有響應用戶點擊或任何其他。

爲什麼此按鈕和圖像在單獨的佈局中不響應用戶事件？

不應該再次創建commonView。

如果你想保持common_status_bar.xml的參考，你可以通過一個ID給它命名，如下面的代碼：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:paddingBottom="10dp" 
     android:paddingLeft="10dp" 
     android:paddingRight="10dp" 
     android:paddingTop="10dp" > 

     <include 
      android:id="@+id/common_status_bar" 
      layout="@layout/common_status_bar" /> 

    </RelativeLayout> 

然後，更改此代碼：

 commonView = layoutInflater.inflate(R.layout.common_status_bar, null); 

到：

 commonView = findViewById(R.id.common_status_bar);
