设置密码后进入活动时，每个活动都要求输入用户密码

Question

我完成了一个Android应用。这是一个财务应用程序，因此其他人一定不能看到所有者的财务。现在，我停止了用户锁定问题。如果用户为应用设置了用户锁，则每次启动Activity都要求输入密码。之前不是那样。仅在用户首次进入应用程序时要求输入密码。我不明白发生了什么。我找不到我的错误。

查看日志没有错误。储物柜位于导航抽屉中，并按了MainActivity。我将SwitchCompat启用和禁用。我删除了其他未提及的代码，只保留了用于用户密码的代码。

应用程序类

public class App extends Application {
private static long TIME_PAUSE = 1500L;
private long mLastPause;
private static App mInstance;

@Override
public void onCreate() {
    super.onCreate();
    mInstance = this;
    new DbHelper(getApplicationContext()).getWritableDatabase();
    this.mLastPause = (System.currentTimeMillis() - TIME_PAUSE);

    FirebaseAuth.getInstance().useAppLanguage();

}

public static App getInstance()
{
    return mInstance;
}

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

public boolean isEnterPassword()
{
    return System.currentTimeMillis() - this.mLastPause >= TIME_PAUSE;
}

MainActivity

public class MainActivity extends BaseActionBar
    implements NavigationView.OnNavigationItemSelectedListener {

@Override
protected void onStart() {
    super.onStart();
    if ((App.getInstance().isEnterPassword()) && (mHelper.isProtectionPassword()) && (getSupportFragmentManager().findFragmentByTag(EnterPasswordDialogFragment.class.getSimpleName()) == null)) {
        showDialog(EnterPasswordDialogFragment.newInstance(this.mHelper.getPassword()));
    }
}

NavigationView navigationView;
SwitchCompat vibrateSwitch;


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

    dbHelper = new DbHelper(this);
    initActionBar();

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

    navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

}

@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.locker) {
        navigationView.getMenu().findItem(R.id.locker).setActionView(new SwitchCompat(this));
        vibrateSwitch = (SwitchCompat) navigationView.getMenu().findItem(R.id.locker).getActionView();

        vibrateSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                mHelper.setProtectionPassword(isChecked);
            }
        });

        if (!vibrateSwitch.isChecked()) {
            if (!this.mHelper.isProtectionPassword()) {
                showDialog(LoginActivity.newInstance(passwordListener));
            }
        }

        vibrateSwitch.setChecked(false);
        this.mHelper.setPassword("");
        this.mHelper.setProtectionPassword(false);
    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

}

SystemHelper

public class SystemHelper {

public static final String settings = "settings";
private Context context;

private SystemHelper(Context context1) {
    this.context = context1;
}

public static SystemHelper getInstance(Context context) {
    return new SystemHelper(context);
}

public SharedPreferences getPreferenses() {
    Context contextL = this.context;
    return contextL.getSharedPreferences("settings", 4);
}


public void setPassword(String paramString) {
    SharedPreferences.Editor localEditor = getPreferenses().edit();
    localEditor.putString("key_password", paramString);
    localEditor.commit();
}

public void setProtectionPassword(boolean paramBoolean) {
    SharedPreferences.Editor localEditor = getPreferenses().edit();
    localEditor.putBoolean("cb_protection_password", paramBoolean);
    localEditor.commit();
}

public boolean isProtectionPassword() {
    return getPreferenses().getBoolean("cb_protection_password", false);
}

public String getPassword() {
    return getPreferenses().getString("key_password", "");
}
