Question

问题：我想有意移动MainActivity，但我将LoginActivity用作主显示，如何在MainActivity不是主显示的同时移至MainActivity？

我想我搞砸了。仍然需要帮助。

LoginActivity.java

public class LoginActivity extends AppCompatActivity implements View.OnClickListener {

EditText etEmail;
EditText etPassword;
Button btnRegister;
Button btnLogin;

public static Intent getIntent(Context context){
    return new Intent (context, LoginActivity.class );
}


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


    ButterKnife.bind(this);
    //setTitle(getString(R.string.activity_main_new_title));
    //enableBackButton();

    setupViews();

}

private void setupViews() {
    btnRegister = (Button) findViewById(R.id.btn_register);
    btnRegister.setOnClickListener(this);
    btnLogin = (Button) findViewById(R.id.btn_login);
    btnLogin.setOnClickListener(this);
}


@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.btn_register:
        Intent intentRegister = new Intent(getApplicationContext(), RegisterActivity.class);
        startActivity(intentRegister);
        break;
        case R.id.btn_login:
        Intent intentLogin = new Intent(getApplicationContext(), MainActivity.class);
        startActivity(intentLogin);
        break;

        default:
            break;
    }
}

}

MainActivity

public class MainActivity extends AppCompatActivity {

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

    startActivity(LoginActivity.getIntent(this));
}

}
