當我簡單地做setContentView（R.layout.somelayout）時，爲什麼會出現內存泄漏？

在我的onCreate（）中，我簡單地使用xml作爲活動的內容視圖。爲什麼我得到內存泄漏。這是我做錯了什麼嗎？當我簡單地做setContentView（R.layout.somelayout）時，爲什麼會出現內存泄漏？

我的xml只有5個圖像按鈕，每個圖像按鈕都有一個statelistdrawable（選擇器）。每個圖像的大小隻有16kb。（所以我正在使用10個圖像 - 每個按鈕的按下狀態圖像和正常狀態圖像）。

在我的活動中無處可用我使用LayoutInflator .. 不應該在從xml設置內容視圖時自行回收bimaps嗎？

我得到的錯誤是這樣的：

我更換了圖像，和代碼工作沒有應用程序掛起來，但stikll我DDMS日誌快要瘋了與以下錯誤：

.. 。。。。

雖然該應用程序正在工作，我想知道我做錯了什麼。或者它是越野車android系統中的錯誤？

附着的代碼：

public class VirtualHomeActivity extends Activity { 

    ImageButton imgbtn1, imgbtn2, imgbtn3, imgbtn4, 
      imgbtn5; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
     setContentView(R.layout.home); 
} 
}

佈局home.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<RelativeLayout android:id="@+id/RelativeLayout01" 
    android:layout_width="fill_parent" android:layout_height="fill_parent" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layoutAnimation="@anim/home_screen_animation_controller" android:background="@drawable/bg_application"> 

    <ImageButton android:id="@+id/imgBtn1" 
     android:layout_width="340dip" android:scaleType="fitCenter" android:layout_height="100dip" android:layout_marginLeft="20dip" android:layout_marginTop="5dip" android:background="@drawable/custombutton1"></ImageButton> 
    <ImageButton android:layout_below="@id/imgBtn1" 
     android:id="@+id/imgBtn2" android:layout_width="340dip" android:scaleType="fitCenter" android:layout_height="100dip" android:layout_marginTop="5dip" android:layout_marginLeft="20dip" android:background="@drawable/custombutton2"></ImageButton> 
    <ImageButton android:layout_below="@id/imgBtn2  android:id="@+id/imgBtn3" android:scaleType="fitCenter" android:layout_width="340dip" android:layout_height="100dip" android:layout_marginLeft="20dip" android:layout_marginTop="5dip" android:background="@drawable/custombutton3"></ImageButton> 
<ImageButton android:layout_below="@id/imgBtnS3" android:id="@+id/imgBtn4" android:scaleType="fitCenter" android:layout_height="100dip" android:layout_width="340dip" android:layout_marginLeft="20dip" android:layout_marginTop="5dip" android:background="@drawable/custombutton4"></ImageButton> 
<ImageButton android:layout_below="@id/imgBtn4" 
    android:id="@+id/imgBtn5" android:scaleType="fitCenter" 
    android:layout_height="100dip" android:layout_width="340dip" 
    android:layout_marginLeft="20dip" android:layout_marginTop="5dip" android:background="@drawable/custombutton5"></ImageButton> 
</RelativeLayout>

和選擇器是：（custombutton1.xml）

<?xml version="1.0" encoding="UTF-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_pressed="true" android:drawable="@drawable/img_clicked" /> 
    <item android:drawable="@drawable/img_unclicked" /> </selector>

我刪除所有其它代碼從檢查我是否正在創建內存泄漏的活動。但在這裏我只是設置內容視圖作爲我的佈局文件，仍然我的ddms說虛擬機不會讓我們分配270000字節

我不認爲我試圖管理任何活動生命週期在這裏。

這不是一個ANdroid錯誤，你的應用程序必須以某種方式泄漏內存，或者你正在加載太多的位圖。請注意，磁盤上圖像的大小並不重要（至少不夠）。圖像的分辨率很重要。 – 2011-03-11 05:43:27

您的內存泄漏可能在其他地方，也許在您如何管理活動生命週期更改。看看文章Avoiding Memory Leaks。

該活動是應用程序中的第一個活動，並且代碼無非是onCreate（Bundle savedInstanceState）{super.onCreate（savedIntanceState）;的setContentView（R.layout.home）;}} – rDroid 2011-03-11 08:27:46

當我簡單地做setContentView（R.layout.somelayout）時，爲什麼會出現內存泄漏？
