我想制作密码保护的Android应用程序,但是在这个简单的程序系统中不匹配两个字符串.

package com.pokmgr;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.text.Editable;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainPM extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.pm_layout);

        final EditText pin = (EditText) findViewById(R.id.pinET); 
        final String pass = pin.getText().toString();
        final String code = "ajaj";
        Button enter = (Button) findViewById(R.id.enterBtn);
        enter.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                if (pass.equals(code)) {
                    Intent in = new Intent(MainPM.this, Menu.class);
                    startActivity(in);
                } …
