致命錯誤：主要。應用程序強制關閉

Question

我設計我的第一個android應用程序，並不斷提出以下錯誤，這是排除我的生活，我不明白它非常好（請找到我的Logcat（詳細），Java代碼（我玩過開始在我的editButton和buttonUpdate位開始工作，這與editStatus有什麼關係？我真的認爲它可能），並且我也放入了我的清單文件：

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.EditText; 


public class LocatorDemoActivity extends Activity implements OnClickListener { 
    EditText editStatus; 
    Button buttonUpdate; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.locationstatus); 

     editStatus = (EditText)findViewById(R.id.edit_status); 
     buttonUpdate = (Button)findViewById(R.id.button_update); 
     buttonUpdate.setOnClickListener(this); 

       //have button 'listen' for click 

    } 

    public void onClick(View arg0) { 
     // TODO Auto-generated method stub 

    } 

}

我有;

試圖做adb kill-server和adb start-server，並在沒有模擬器的情況下運行它，如另一篇文章中的建議。請稍微理解一下，因爲我對eclipse和Java的知識相當低，並且即時學習。

請幫

Answer 1

由於從這個錯誤中看出：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.locator.demo/com.locator.demo.LocatorDemoActivity}: java.lang.ClassCastException: android.widget.TextView

這一個：

Caused by: java.lang.ClassCastException: android.widget.TextView

您試圖蒙上了TextView到EditText（在這一行：editStatus = (EditText)findViewById(R.id.edit_status);） 。

轉到locationstatus.xml，並更改TextView與ID edit_status到EditText。
