实现页面跳转

1、打开第一个页面的“MainAbilitySlice.java”文件，添加按钮的响应逻辑，实现点击按钮跳转到下一页，示例代码如下：

import com.example.firstdemo.ResourceTable;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.Button;

public class MainAbilitySlice extends AbilitySlice {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_main);
        Button button = (Button) findComponentById(ResourceTable.Id_button);
        // 点击按钮跳转至第二个页面
        button.setClickedListener(listener -> present(new SecondAbilitySlice(), new Intent()));
    }

    @Override
    public void onActive() {
        super.onActive();
    }

    @Override
    public void onForeground(Intent intent) {
        super.onForeground(intent);
    }
}

2、再次运行项目，效果如下图所示
