每当我尝试运行我的应用程序时，它会显示一个对话框，说明应用程序已经意外停止，无论是在手机还是模拟器上。该程序没有错误，我已经尝试清理我的项目和几个解决方案，但没有他们工作。即使是hello world项目，几个项目也会出现同样的问题。
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) {

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();
}
}

我是Android应用程序开发的新手，但我认真尝试了我能找到的每个解决方案。如果有人能帮我找到合适的解决方案。

答案 0 :(得分：0)
如果从堆栈跟踪的底部开始，您的资源FileNotFoundException为2E5894。
因为看起来你的代码/布局中引用drawable的唯一部分是单ImageView，并且它使用启动器图标我将从清理和重建你的项目开始确定有些奇怪的事情没有发生。 Eclipse尤其习惯于有时会搞砸资源。
如果这不起作用，那么您应该能够查看生成的R课程，找出哪些有问题的资源，并尝试找出设备认为它丢失的原因
修改
你的评论暗示了一个可能是原因的问题。
颜色资源应声明为color标记而不是字符串：
<resources>
<color name="my_color">#ffffffff</color>
</resources>
然后当您在视图中使用它们时：
<TextView
android:textColor="@color/my_color" />
答案 1 :(得分：-1)
这是布局xml文件中的资源未找到异常。
