動態ListAcitvity中的按鈕事件android

Question

嗨，我已經生成了一個動態列表。我有SeekBar和一個ToggleButton列表中的每一行。我一直試圖爲切換生成事件，並從最後1周尋找，但徒勞無功。請幫助我。

下面是XML代碼清單（smartunits.xml）

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/unitsLayout" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:background="@drawable/grid_gradient" 
    android:orientation="vertical" > 
    <ListView 
     android:id="@android:id/android:list" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" > 
    </ListView> 

</LinearLayout> 

現在每行（listunits.xml）代碼

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

    <TextView 
     android:id="@+id/unitName" 
     android:layout_width="40px" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:padding="20px" 
     android:textColor="#ffffff" /> 

    <TextView 
     android:id="@+id/unitCodeId" 
     android:layout_width="1dp" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:textColor="#ffffff" 
     android:visibility="invisible" /> 

    <SeekBar 
     android:id="@+id/unitsseek" 
     android:layout_width="200dp" 
     android:layout_height="wrap_content" 
     android:layout_marginTop="10dp" /> 

    <ToggleButton 
     android:id="@+id/toggle" 
     android:layout_width="40dp" 
     android:layout_height="40dp" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentRight="true" 
     android:layout_marginLeft="5dp" 
     android:background="@drawable/off_grey" 
     android:textOff="" 
     android:textOn="" /> 

</LinearLayout> 

這裏是ListActivity

代碼

import android.app.ListActivity; 
import android.database.Cursor; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.SimpleCursorAdapter; 
import android.widget.ToggleButton; 

public class UnitsListActivity extends ListActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 

     super.onCreate(savedInstanceState); 

     // put the bottom code here 

     setContentView(R.layout.smartunits); 

     Bundle extras = getIntent().getExtras(); 

     final AutomationDBAccessor db = new AutomationDBAccessor(this); 
     Cursor cUnits = db.getUnits(extras.getInt("roomFloorId"), extras.getInt("roomId")); 

     String[] from = new String[] { AutomationDBAccessor.colUnitName, AutomationDBAccessor.colUnitCodeID }; 
     int[] to = new int[] { R.id.unitName, R.id.unitCodeId }; 
     SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.listunits, cUnits, from, to); 

     this.setListAdapter(sca); 

     View viewUnits = LayoutInflater.from(getBaseContext()).inflate(R.layout.listunits, null); 
     final ToggleButton toggle = (ToggleButton) viewUnits.findViewById(R.id.toggle); 

     toggle.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { // TODO Auto-generated method stub 

       if (toggle.isChecked()) { 

        toggle.setBackgroundDrawable(getResources().getDrawable(R.drawable.on)); 
       } else { 
        toggle.setBackgroundDrawable(getResources().getDrawable(R.drawable.off_grey)); 

       } 

      } 
     }); 
    } 
} 

現在我無法處理ToggleButton事件。

我從來沒有嘗試這個，但你可以做這樣的事情，

在你listunits.xml

<ToggleButton 
    android:id="@+id/toggle" 
    android:layout_width="40dp" 
    android:layout_height="40dp" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentRight="true" 
    android:layout_marginLeft="5dp" 
    android:textOff="" 
    android:textOn="" 
    android:onClick="toggleButtonClick" /> 

而在你UnitsListActivity

寫這個方法..

public void toggleButtonClick(View view) 
{ 
    ToggleButton toggle = (ToggleButton) view; 

    if (toggle.isChecked()) { 
     toggle.setBackgroundDrawable(getResources().getDrawable(R.drawable.on)); 
    } else { 
     toggle.setBackgroundDrawable(getResources().getDrawable(R.drawable.off_grey)); 
    } 
} 

運行此代碼並讓我知道發生了什麼..
