应用程序无法启动。应用程序意外停止

Question

每次尝试运行我的应用程序时，都会显示一个对话框，说明应用程序在手机和模拟器上意外停止。该程序没有错误，我试图清理我的项目和几个解决方案，但没有工作。几个项目甚至是hello world项目都会出现同样的问题。

这是我的主要活动：MainActivity.java

package com.noura.luba; 

import android.app.Activity; 
import android.app.Dialog; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.TextView; 
import android.widget.Toast; 

public class MainActivity extends Activity { 


    TextView forgotPass, createAcc; 
    Button loginButton; 
    EditText userID, pass; 
    LoginDataBaseAdapter loginDataBaseAdapter; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_main); 

      loginDataBaseAdapter=new LoginDataBaseAdapter(this); 
      loginDataBaseAdapter=loginDataBaseAdapter.open(); 

      forgotPass= (TextView)findViewById(R.id.forgotPasswordTextView); 
      createAcc= (TextView)findViewById(R.id.createAccountTextView); 
      loginButton= (Button)findViewById(R.id.loginButton); 
      userID=(EditText)findViewById(R.id.userIDEditText); 
      pass=(EditText)findViewById(R.id.passwordEditText); 

      createAcc.setOnClickListener(new View.OnClickListener() { 

       public void onClick(View v) { 

        Intent intentCreateAcc = new Intent(getApplicationContext(), CreateAccActivity.class); 
        startActivity(intentCreateAcc); 

       } 
      }); 

      forgotPass.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
      Intent intentForgotPass = new Intent(getApplicationContext(), ForgotPassActivity.class); 
       startActivity(intentForgotPass); 
      } 
      }); 

      loginButton.setOnClickListener(new View.OnClickListener() { 
       public void onClick(View v) { 

        String id=userID.getText().toString(); 

        Intent intentLogin = new Intent(getApplicationContext(), Home.class); 

        intentLogin.putExtra("User_ID", id); 
        startActivity(intentLogin); 

       } 

      }); 


    } 

    public void LogIn(View V) 
    { 

     final Dialog dialog = new Dialog(MainActivity.this); 

     dialog.setContentView(R.layout.activity_main); 
     dialog.setTitle("LUBA LogIn"); 

     final EditText userID=(EditText)dialog.findViewById(R.id.userIDEditText); 
     final EditText pass=(EditText)dialog.findViewById(R.id.passwordEditText); 

     Button login = (Button)dialog.findViewById(R.id.loginButton); 


     //Set On ClickListener 
     login.setOnClickListener(new View.OnClickListener() { 

      public void onClick(View v) { 

       String userName= userID.getText().toString(); 
       String password=pass.getText().toString(); 

       String storedPassword = loginDataBaseAdapter.getSingleEntry(userName); 

       if(password.equals(storedPassword)) 
       { 
        Toast.makeText(MainActivity.this, "Login Successful", Toast.LENGTH_LONG).show(); 
        dialog.dismiss(); 

       } 
       else 
       { 

        Toast.makeText(MainActivity.this, "User Name and Password do not match", Toast.LENGTH_LONG).show(); 

       } 
      } 
     }); 

     dialog.show(); 
    } 



    protected void onDestroy() { 

     super.onDestroy(); 

     loginDataBaseAdapter.close(); 

    } 


}

Answer 1

它是在布局XML文件中的资源未发现异常。

1. 检查是否所有的维数值都可用。
2. 检查所有的字符串声明是否正确。
3. 检查noura布局是否正确可用。

Answer 2

如果你开始在你有一个堆栈跟踪的底部FileNotFoundException资源2E5894。

因为它看起来像引用可绘制的代码/布局的唯一部分是单个ImageView它使用启动器图标我会开始清理和重建项目，以确保没有发生奇怪的事情发生。 Eclipse尤其习惯于有时会搞砸资源。

如果这不起作用，那么你应该能够查看生成的R类，并找出哪些有问题的资源，并试着找出设备认为它缺失的原因。

您的评论暗示这可能是原因的问题。

颜色资源应该被声明为color标签不是字符串：

<resources> 
    <color name="my_color">#ffffffff</color> 
</resources> 

然后，当你在你的视图中使用它们：

<TextView 
    android:textColor="@color/my_color" />
