### HarmonyOS 不带参数界面之间跳转 ###

package com.example.myapplication.slice;
    import com.example.myapplication.ResourceTable;
    import ohos.aafwk.ability.AbilitySlice;
    import ohos.aafwk.content.Intent;
    import ohos.agp.components.Button;
    import ohos.agp.components.Component;
    
    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);
            button.setClickedListener(new Component.ClickedListener() {
                @Override
                public void onClick(Component component) {
                    present(new IntentAbilitySlice(), new Intent());
                }
            });
    
        }
    
    
        @Override
        public void onActive() {
            super.onActive();
        }
    
        @Override
        public void onForeground(Intent intent) {
            super.onForeground(intent);
        }
    }

### HarmonyOS 界面跳转的同时传递参数 ###

传递参数界面代码

package com.example.myapplication.slice;
    import com.example.myapplication.ResourceTable;
    import ohos.aafwk.ability.AbilitySlice;
    import ohos.aafwk.content.Intent;
    import ohos.agp.components.Button;
    import ohos.agp.components.Component;
    
    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);
            button.setClickedListener(new Component.ClickedListener() {
                @Override
                public void onClick(Component component) {
                    Intent intent1 = new Intent();
                    intent1.setParam("key","有点困了");
                    present(new IntentAbilitySlice(), intent1);
                }
            });
    
        }
    
    
        @Override
        public void onActive() {
            super.onActive();
        }
    
        @Override
        public void onForeground(Intent intent) {
            super.onForeground(intent);
        }
    }

接受值界面代码

package com.example.myapplication.slice;
    
    import com.example.myapplication.ResourceTable;
    import ohos.aafwk.ability.AbilitySlice;
    import ohos.aafwk.content.Intent;
    import ohos.agp.components.Text;
    
    public class IntentAbilitySlice extends AbilitySlice {
    
        @Override
        protected void onStart(Intent intent) {
            super.onStart(intent);
            super.setUIContent(ResourceTable.Layout_intent_ability_slice_layout);
    
            Text text = (Text) findComponentById(ResourceTable.Id_text);
            if (intent != null) {
                text.setText("接受的值为:" + intent.getStringParam("key"));
            }
    
        }
    }
