Eclipse android错误将焦点设置为：org.Eclipse.e4.ui.model.application.ui.basic.impl.PartImpl Manager.java

当我尝试运行我的应用程序时，我不断地遇到这个错误，问题是我删除了我的manager类，所以我不知道错误来自哪里。我怀疑我的主要活动中出现了try，catch异常，但尝试将其删除，但我的应用程序仍然无法打开，这是代码

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

    Button logbtn = (Button)findViewById(R.id.logbutton);
    Button regbtn = (Button)findViewById(R.id.regbutton);
    logbtn.setOnClickListener(this);
    regbtn.setOnClickListener(this);
}

@Override
public void onClick(View args) {
    // TODO Auto-generated method stub
    switch(args.getId()){
        case R.id.logbutton:
            String email = em.getText().toString();
            String pword = pw.getText().toString();
            boolean didItWork = true;
            MySqlDB details = new MySqlDB(this);
            try {
                details.open();
                boolean data = details.checkData(email, pword);
                details.close();

                if (data == true) {
                    Intent i = new Intent(MainActivity.this, MainHomepage.class);
                startActivity(i);
                }
            } catch(Exception e) {
                didItWork = false;
                String error = e.toString();
                Dialog d = new Dialog(this);
                d.setTitle("oops!");
                TextView tv = new TextView(this);
                tv.setText(error);
                d.setContentView(tv);
                d.show();
            } finally {
                if (didItWork) {
                    Dialog d = new Dialog(this);
                    d.setTitle("Yay!!");
                    TextView tv = new TextView(this);
                    tv.setText("Successful!");
                    d.setContentView(tv);
                    d.show();
                }
            }
            break;
        case R.id.regbutton:
            Intent i = new Intent(MainActivity.this, MainRegister.class);
            startActivity(i);
            break;
    }
}

你的按钮是在班级级别声明的吗

public class SomeActivity extends Activity implements View.OnClickListener
{
    private Button logbtn;
    private Button regbtn;

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

        logbtn = (Button)findViewById(R.id.logbutton);
        regbtn = (Button)findViewById(R.id.regbutton);
        logbtn.setOnClickListener(this);
        regbtn.setOnClickListener(this);
    }
    ...
}

我们可以看看logcat的输出吗？

**这是eclipse中的一个bug**

除了“在Java（引用）搜索期间终止调试会话”之外，没有其他内容

我添加了logcat，并尝试声明按钮，但没有解决任何问题。
