该项目采用了项目模板full srceen和卡片模板immersive,通过两种卡片结合更容易设计

六、关键代码(MainAbility)与样式实现

public class MainAbility extends Ability {

public static final int DEFAULT_DIMENSION_2X2 = 2;

public static final int DIMENSION_1X2 = 1;

public static final int DIMENSION_2X4 = 3;

public static final int DIMENSION_4X4 = 4;

private static final int INVALID_FORM_ID = -1;

private static final HiLogLabel TAG = new HiLogLabel(HiLog.DEBUG, 0x0, MainAbility.class.getName());

private String topWidgetSlice;

@Override

public void onStart(Intent intent) {

    super.onStart(intent);

    super.setMainRoute(MainAbilitySlice.class.getName());

    if (intentFromWidget(intent)) {

        topWidgetSlice = getRoutePageSlice(intent);

        if (topWidgetSlice != null) {

            setMainRoute(topWidgetSlice);

        }

    }

    stopAbility(intent);

}

@Override

protected ProviderFormInfo onCreateForm(Intent intent) {

    HiLog.info(TAG, "onCreateForm");

    long formId = intent.getLongParam(AbilitySlice.PARAM_FORM_IDENTITY_KEY, INVALID_FORM_ID);

    String formName = intent.getStringParam(AbilitySlice.PARAM_FORM_NAME_KEY);

    int dimension = intent.getIntParam(AbilitySlice.PARAM_FORM_DIMENSION_KEY, DEFAULT_DIMENSION_2X2);

    HiLog.info(TAG, "onCreateForm: formId=" + formId + ",formName=" + formName);

    FormControllerManager formControllerManager = FormControllerManager.getInstance(this);

    FormController formController = formControllerManager.getController(formId);

    formController = (formController == null) ? formControllerManager.createFormController(formId,

            formName, dimension) : formController;

    if (formController == null) {

        HiLog.error(TAG, "Get null controller. formId: " + formId + ", formName: " + formName);

        return null;

    }

    return formController.bindFormData();

}

@Override

protected void onUpdateForm(long formId) {

    HiLog.info(TAG, "onUpdateForm");

    super.onUpdateForm(formId);

    FormControllerManager formControllerManager = FormControllerManager.getInstance(this);

    FormController formController = formControllerManager.getController(formId);

    formController.updateFormData(formId);

}

@Override

protected void onDeleteForm(long formId) {

    HiLog.info(TAG, "onDeleteForm: formId=" + formId);

    super.onDeleteForm(formId);

    FormControllerManager formControllerManager = FormControllerManager.getInstance(this);

    formControllerManager.deleteFormController(formId);

}

@Override

protected void onTriggerFormEvent(long formId, String message) {

    HiLog.info(TAG, "onTriggerFormEvent: " + message);

    super.onTriggerFormEvent(formId, message);

    FormControllerManager formControllerManager = FormControllerManager.getInstance(this);

    FormController formController = formControllerManager.getController(formId);

    formController.onTriggerFormEvent(formId, message);

}

@Override

public void onNewIntent(Intent intent) {

    if (intentFromWidget(intent)) { // Only response to it when starting from a service widget.

        String newWidgetSlice = getRoutePageSlice(intent);

        if (topWidgetSlice == null || !topWidgetSlice.equals(newWidgetSlice)) {

            topWidgetSlice = newWidgetSlice;

            restart();

        }

    }

}

private boolean intentFromWidget(Intent intent) {

    long formId = intent.getLongParam(AbilitySlice.PARAM_FORM_IDENTITY_KEY, INVALID_FORM_ID);

    return formId != INVALID_FORM_ID;

}

private String getRoutePageSlice(Intent intent) {

    long formId = intent.getLongParam(AbilitySlice.PARAM_FORM_IDENTITY_KEY, INVALID_FORM_ID);

    if (formId == INVALID_FORM_ID) {

        return null;

    }

    FormControllerManager formControllerManager = FormControllerManager.getInstance(this);

    FormController formController = formControllerManager.getController(formId);

    if (formController == null) {

        return null;

    }

    Class<? extends AbilitySlice> clazz = formController.getRoutePageSlice(intent);

    if (clazz == null) {

        return null;

    }

    return clazz.getName();

}

}
