HarmonyOS实现页面跳转,
实现页面跳转
- 打开第一个页面的“MainAbilitySlice.java”文件,重写onStart()方法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:
- package com.example.myapplication.slice;
-
- import com.example.myapplication.ResourceTable;
- import ohos.aafwk.ability.AbilitySlice;
- import ohos.aafwk.content.Intent;
- import ohos.aafwk.content.Operation;
- import ohos.agp.components.*;
-
- public class MainAbilitySlice extends AbilitySlice {
-
- @Override
- public void onStart(Intent intent) {
- super.onStart(intent);
- super.setUIContent(ResourceTable.layout_main_layout);
- Button button = (Button) findComponentById(ResourceTable.Id_button);
-
- IF (button != null) {
- // 为按钮设置点击回调
- button.setClickedListener(new Component.ClickedListener() {
- @Override
- public void onClick(Component component) {
- Intent secondIntent = new Intent();
- // 指定待启动FA的bundleName和abilityName
- Operation operation = new Intent.OperationBuilder()
- .withDeviceId(““)
- .withBundleName(“com.example.myapplication“)
- .withAbilityName(“com.example.myapplication.SecondAbility“)
- .build();
- secondIntent.setOperation(operation);
- startAbility(secondIntent); // 通过AbilitySlice的startAbility接口实现启动另一个页面
- }
- });
- }
- }
-
- @Override
- public void onActive() {
- super.onActive();
- }
-
- @Override
- public void onForeground(Intent intent) {
- super.onForeground(intent);
- }
- }
- 再次运行项目,效果如图所示:
