編輯：我想通了什麼錯了，就像我說過的，我將包名從com.musicbynumbers.pianoscales更改爲com.musicbynumbers.pianoscalesfull。但我忘了Android：圖片不顯示在照片顯示中活動
change int id =getResources().getIdentifier("com.musicbynumbers.pianoscalesfull:drawable/" + gotScale, null, null);
所有的代碼是好的。非常感謝你的幫助。
好的，這只是一些beckground信息，然後才進入確切的問題： 我正在使用eclipse。幾個星期前，我在遊戲商店發佈了我的第一款應用程序 - 鋼琴秤應用程序，並獲得了許可。兩天前，我意識到許可證阻止了一些支付應用程序的用戶使用它。我評論了許可，並去了更新，但我的密鑰庫已損壞。所以我從商店中刪除了應用程序並更改了軟件包名稱。該應用程序是一個菜單，可以顯示所選圖像的顯示Activity。當我再次測試應用程序時，我發現只顯示默認的Android圖像。我不認爲我改變了子菜單中的任何代碼或顯示活動，因爲它正在工作，但我仍然會把它們放在一起。順便說一下，這是我的第一個應用程序，該應用程序將在明天發佈，並隨附一本書，因此對我來說這是一個真正的第11個小時的情況。
這是幾個子菜單中的一個通向活動「顯示」

這是顯示所選擇的圖像，但只有現在正在顯示默認的顯示活動。
package com.musicbynumbers.scales;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;
import com.musicbynumbers.pianoscalesfull.R;
public class display extends Activity {
ImageView displayScale;
String gotScale;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.display);
Initalize();
gotScale = getIntent().getStringExtra("key");
ImageView displayScale = (ImageView) findViewById(R.id.displayImage);
//aflatmaj-gotscale
int id = getResources().getIdentifier("com.musicbynumbers.pianoscales:drawable/" + gotScale, null, null);
displayScale.setImageResource(id);
}
private void Initalize() {
// TODO Auto-generated method stub
displayScale = (ImageView) findViewById(R.id.displayImage);
gotScale = "ic_launcher.png";
}}
我真的很感激任何幫助，因爲我沒有時間了。

我看到，Iv'e改變第二個在OnCreate到displayScale =（ImageView的）findViewById（R.id.displayImage）;並即時測試它在模擬器上 – 2013-03-11 18:17:42
剛剛嘗試過，它仍然只是顯示默認圖像。 – 2013-03-11 18:19:39
