不同Page间的AbilitySlice导航_ability 导航的方法

可以通过配置Intent的Action导航到目标AbilitySlice。Page间的导航可以使用startAbility()或startAbilityForResult()方法，获得返回结果的回调为onAbilityResult()。在Ability中调用setResult()可以设置返回结果。

页面布局比较简单，就略过了。

具体请看代码：

  @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_main);
        //通过ID找到xml中的button控件
        Button button = (Button) findComponentById(ResourceTable.Id_main_button);
        //设置点击监听事件
        button.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                //点击跳转
//                presentForResult(new SecondSlice(),new Intent(),110);
                Intent intentNew = new Intent();
                Operation operation = new Intent.OperationBuilder().withDeviceId("")
                        .withBundleName(getBundleName())
                        .withAbilityName(OtherAbility.class)
                        .build();
                intentNew.setOperation(operation);
                intentNew.setParam("key","我从mainAbility到otherAbility");
                startAbilityForResult(intentNew,112);
 
            }
        });
 
    }

这是跳转的代码。

通过onAbilityResult方法接收回调结果

 
    @Override
    protected void onAbilityResult(int requestCode, int resultCode, Intent resultData) {
        if (resultCode != 0 || resultData == null) {
            return;
        }
        LogUtil.info("onAbilityResult requestCode",requestCode+"  resultCode = "+resultCode);
        String str_text = resultData.getStringParam("key");
        text.setText(str_text);
    }

这是接收返回结果的代码。

@Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_other);
        Text textShow = (Text) findComponentById(ResourceTable.Id_other_text_show);
        textShow.setText(intent.getStringParam("key"));
        Button btn_other = (Button) findComponentById(ResourceTable.Id_btn_other_ability);
        btn_other.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                //结束当前页面
                terminate();
            }
        });
 
    }
 
    @Override
    public void onActive() {
        super.onActive();
        //设置传递内容
        Intent intent = new Intent();
        intent.setParam("key","我是从otherAbility回到MainAbility");
        getAbility().setResult(0,intent);
    }

在另一个Page abilitySlice在onActive方法设置回传的内容。

这就是Page间的导航。
