扩展实现ToolBar的基本活动时，活动中未显示工具栏

时间：2018-08-07 16:43:47

标签： java android android-activity android-toolbar android-menu

我是一名初学者Android开发人员，我一直在努力解决在继承基本活动的任何活动中都看不到工具栏的问题。根据其他资源，在不同的活动中使用相同的工具栏。我必须在基本活动中实现它，并在需要使用它的地方继承它。有人可以帮我解决问题吗？

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_welcome);

    final Button databaseButton = findViewById(R.id.database);

        public void onClick(View v) {
            // Code here executes on main thread after user presses button
            Intent databaseIntent = new Intent(WelcomeActivity.this, Questionnaire.class);
            startActivity(databaseIntent);
        }
    });
}

1 个答案:

答案 0 :(得分：0)

答案实际上很简单。您首先在BaseActivity类的OnCreate()方法中设置contentview，然后在子类的OnCreate()方法中将视图更改为另一个xml文件。

我建议您不要在BaseActivity类中实现OnCreate()方法，而在BaseActivity中实现SetContentView()方法。

简而言之，请从BaseActivity（）中删除onCreate()方法，然后在下面添加setContentView()方法。

@Override
public void setContentView(int layoutResID) {
    super.setContentView(layoutResID);
    Toolbar toolbar = findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}

P.S-您的quiz_menu.xml文件看起来不像菜单文件。 :) P.P.S-让我知道它是否有效，或者遇到麻烦。 ：）
