參考/實現接口的Android崩潰

Question

我是來自Java背景的Android新手。所以請原諒，如果這是一個非常簡單的修復。我在java中創建了一個機器模擬器，我想用一個簡單的UI在Android上運行它。問題是，它崩潰，當我做到這一點

public class UITerminal extends EditText implements Terminal 

我也試過這個類

Terminal terminal; 
public void init() 
{ 
     terminal = new Terminal() 
     { 
     //implemented methods 
     } 
} 

這兩種解決方案墜毀在開口內。有關我應該怎麼做的任何建議？提前致謝。這是我第一次體驗Android。

我點擊應用程序，它顯示「不幸的是MyTronEmulator已停止工作」

Answer 1

這是一段時間了，但我試圖使用Java 1.7庫。 Android只支持多達1.6 祝我的錯誤只會說:)

Answer 2

你必須確保你的IDE是出口.jar文件，就加入它的頂部作爲圖書館。否則，假定它已經在電話/模擬器上。

在eclipse中，您可以通過右鍵單擊項目 - >構建路徑 - >配置構建路徑 - >排序並導出 - >檢查庫來確保完成此操作。
