HarmonyOS Activity页面跳转

1.同一activity间slice跳转

2.跳转不同activity

一 同一activity间slice跳转

日志类：声明+调用

public static final HiLogLabel hiLogLabel = new HiLogLabel(HiLog.LOG_APP, 0x00201, "ligy");

 HiLog.info(hiLogLabel,"onClick 方法");

1.跳转到第二个slice

 Button btn = (Button) findComponentById(ResourceTable.Id_btnNext);

        //跳转slice
        btn.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                present(new NextSlice(),new Intent());
                HiLog.info(hiLogLabel,"onClick 方法");
            }
        });

2.传值+回传

//跳转slice：传值+回传
        btn.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                Intent param = new Intent();
                param.setParam("id", "1");
                param.setParam("name", "jack1");
                presentForResult(new NextSlice(), param, 100);
            }
        });

 @Override
    protected void onResult(int requestCode, Intent resultIntent) {
        super.onResult(requestCode, resultIntent);

        if (requestCode == 100) {
            if (resultIntent != null) {
                String msg = resultIntent.getStringParam("msg");
                HiLog.info(hiLogLabel, "回传值：" + msg);
            }
        }
    }

public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_next);

        if(intent != null){
            HiLog.info(hiLogLabel, intent.getStringParam("id"));
            HiLog.info(hiLogLabel, intent.getStringParam("name"));
        }

        Button btn = (Button)findComponentById(ResourceTable.Id_btnUp);
        btn.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                Intent t = new Intent();
                t.setParam("msg","这是next返回的值");

                //present(new MainAbilitySlice(),t);
                setResult(t);
                terminate();
            }
        });
    }

二 跳转不同activity

1.跳转到第二个activity

//跳转Ability
        btn.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                Intent intent1 = new Intent();
                Operation operation = new Intent.OperationBuilder()
                        .withDeviceId("")
                        .withBundleName("com.example.myapplication3")
                        .withAbilityName("com.example.myapplication3.TestAbility")
                        .build();
                intent1.setOperation(operation);

                startAbility(intent1);
            }
        });

2.传值+回传
