startActivity（）被android系统调用了无限次

问题:- startActivity（）被android系统调用了无限次。下面的代码打开了MainActivity，但随后MainActivity被冻结/挂起，几分钟后android自动关闭

我有两项活动：

注册活动

主要活动

注册过程完成后，我想将用户重定向到主屏幕（即MainActivity），因此我使用以下代码启动活动：--

但是startActivity（）被android系统调用了无数次。我是通过Logcat发现的。logcat输出为：--

主要活动代码：

     public class MainActivity extends Activity {
AlertDialog.Builder builder;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    builder = new AlertDialog.Builder(this);

    Button btnEnter = (Button) findViewById(R.id.btnEnter);
    btnEnter.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            if (RegisterActivity.loggedIn) {
                startActivity(new Intent(MainActivity.this,
                        AddActivity.class));
            } else {
                Utility.showAlertDialog(builder, "Please Log In!");
            }
        }

    Button btnSettings = (Button) findViewById(R.id.btnSettings);
    btnSettings.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            startActivity(new Intent(MainActivity.this,
                    RegisterActivity.class));
        }
    });

}

    public class RegisterActivity extends Activity {
     protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.register);
    builder = new AlertDialog.Builder(this);
    etName = (TextView) findViewById(R.id.etName);
    etEmail = (TextView) findViewById(R.id.etEmail);
    Button btnSubmit = (Button) findViewById(R.id.btnSubmit);
    btnsubmit.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(RegisterActivity.this,
                    MainActivity.class);
            startActivity(intent);

        }
    });
    }
}

注册表活动代码：

     public class MainActivity extends Activity {
AlertDialog.Builder builder;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    builder = new AlertDialog.Builder(this);

    Button btnEnter = (Button) findViewById(R.id.btnEnter);
    btnEnter.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            if (RegisterActivity.loggedIn) {
                startActivity(new Intent(MainActivity.this,
                        AddActivity.class));
            } else {
                Utility.showAlertDialog(builder, "Please Log In!");
            }
        }

    Button btnSettings = (Button) findViewById(R.id.btnSettings);
    btnSettings.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            startActivity(new Intent(MainActivity.this,
                    RegisterActivity.class));
        }
    });

}

    public class RegisterActivity extends Activity {
     protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.register);
    builder = new AlertDialog.Builder(this);
    etName = (TextView) findViewById(R.id.etName);
    etEmail = (TextView) findViewById(R.id.etEmail);
    Button btnSubmit = (Button) findViewById(R.id.btnSubmit);
    btnsubmit.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(RegisterActivity.this,
                    MainActivity.class);
            startActivity(intent);

        }
    });
    }
}

这个logcat输出是连续的，直到我关闭模拟器！如果我不关闭模拟器，android会自动重启。简单地说，系统挂起是因为它无限地调用startActivity（）

其实是我的错。。！startActivity（）被无限调用，因为当我完成活动时，我又开始了另一个活动！。。但我感谢所有的响应者的善意帮助。非常感谢你

发布更多代码。我猜你是在循环中调用performClick之类的。或者是在你的家庭活动中尝试删除finish（）请发布注册活动的完整代码我们可以这样做吗？我删除了finish（）但不起作用
