AppCompatActivity的界面

Question

我想扩展AppCompatActivity，Fragment活动，因为我使用此代码

import React from 'react';
import renderer from 'react-test-renderer';
import { reduxForm } from 'redux-form';
import { createStore } from 'redux';
import { Provider } from 'react-redux';
import { mount } from 'enzyme'
import TodoItem from './TodoItem';
import injectTapEventPlugin from 'react-tap-event-plugin';

function setup() {
    const spy = jest.fn();
    const store = createStore(() => ({}));

    const Decorated = reduxForm({ form: 'testForm' })(TodoItem);
    const props = {
        remove: jest.fn(),
        TodoItemReduxFormInitialName: "fullName",
        snapshotTestId:"4"
    }
    const mockedComponent = <Provider store={store}>
                                <Decorated {...props} />
                            </Provider>;

    const enzymeWrapper = mount(mockedComponent)

    injectTapEventPlugin();

    return {
        props,
        mockedComponent,
        enzymeWrapper
    }
}
describe('TodoItem Component', () => {
    it('should render the snapshot', () => {
        const {mockedComponent} = setup()
        const tree = renderer.create(
            mockedComponent
        ).toJSON();
        expect(tree).toMatchSnapshot();
    });


    //not required as snapshot testing covers it
    it('should render Number', () => {
        const {enzymeWrapper} = setup()
        const fieldProps = enzymeWrapper.find('Field').at(0).props();
        expect(fieldProps.hintText).toEqual('Item Number');
        expect(fieldProps.name).toEqual('fullName.itemNumber');
    });


    //not required as snapshot testing covers it
    it('should render remove button', () => {
        const {enzymeWrapper} = setup()
        const button = enzymeWrapper.find('RaisedButton').at(0).props();
        expect(button.label).toEqual("remove")
    });
});

我的Java文件希望扩展AppCompatActivity，但我在该Activity中使用map，因此它已经扩展了FragmentActivity

由于Java不支持多重继承，我可以使用任何接口而不是AppCompatActivity或FragmentActivity吗？

Answer 1

AppCompatActivity是FragmentActivity的子类。因此，您可以使用AppCompatActivity代替FragmentActivity。

如果您不想使用AppCompatActivity，请使用setActionBar(toolbar)代替setSupportActionBar(toolbar)
