Installation and Usage

Find the matching version information in the release address of a third-party library: @react-native-oh-library/react-native-hole-view Releases.For older versions that are not published to npm, please refer to the installation guide to install the tgz package.

Go to the project directory and execute the following instruction:

npm

npm install @react-native-oh-tpl/react-native-hole-view

yarn

yarn add @react-native-oh-tpl/react-native-hole-view

The following code shows the basic use scenario of the repository:

[!WARNING] The name of the imported repository remains unchanged.

import React, {useCallback, useEffect, useState} from 'react';
import {
    ScrollView,
    View,
    Text, TouchableOpacity,
} from 'react-native';

import {RNHole, RNHoleView, ERNHoleViewTimingFunction, IRNHoleViewAnimation} from "react-native-hole-view/src";

import Video from 'react-native-video';

const firstHole: RNHole = {x: 150, y: 390, width: 120, height: 120, borderRadius: 60};
const secondHole: RNHole = {x: 150, y: 40, width: 120, height: 120, borderRadius: 60};

const animationSettings: IRNHoleViewAnimation = {timingFunction: ERNHoleViewTimingFunction.EASE_IN_OUT, duration: 200};

const App = () => {
    const [holes, setHoles] = useState<RNHole[]>([]);
    const [animated, setAnimated] = useState<boolean>(false);
    const [animation, setAnimation] = useState<IRNHoleViewAnimation | undefined>(undefined);

    const onPress = useCallback(() => {
        if (animated) {
            setHoles([firstHole]);
        } else {
            setHoles([secondHole])
        }

        setAnimation({...animationSettings});
        setAnimated(!animated);
    }, [animated, animation])

    useEffect(() => {
        onPress();
    }, []);

    );

export default App;

Link

Currently, HarmonyOS does not support AutoLink. Therefore, you need to manually configure the linking.

Open the harmony directory of the HarmonyOS project in DevEco Studio.

1. Adding the overrides Field to oh-package.json5 File in the Root Directory of the Project

{
  ...
  "overrides": {
    "@rnoh/react-native-openharmony" : "./react_native_openharmony"
  }
}

2. Introducing Native Code

Currently, two methods are available:

Method 1 (recommended): Use the HAR file.

[!TIP] The HAR file is stored in the harmony directory in the installation path of the third-party library.

Open entry/oh-package.json5 file and add the following dependencies:

"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@react-native-oh-tpl/react-native-hole-view": "file:../../node_modules/@react-native-oh-tpl/react-native-hole-view/harmony/rnoh_holeview.har"
  }

Click the sync button in the upper right corner.

Alternatively, run the following instruction on the terminal:

cd entry
ohpm install

Method 2: Directly link to the source code.

[!TIP] For details, see Directly Linking Source Code.

3. Configuring CMakeLists and Introducing HoleViewPackage

Open entry/src/main/cpp/CMakeLists.txt and add the following code:

project(rnapp)
cmake_minimum_required(VERSION 3.4.1)
set(CMAKE_SKIP_BUILD_RPATH TRUE)
set(RNOH_APP_DIR "${CMAKE_CURRENT_SOURCE_DIR}")
set(NODE_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../node_modules")
+ set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
set(RNOH_CPP_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../react-native-harmony/harmony/cpp")
set(LOG_VERBOSITY_LEVEL 1)
set(CMAKE_ASM_FLAGS "-Wno-error=unused-command-line-argument -Qunused-arguments")
set(CMAKE_CXX_FLAGS "-fstack-protector-strong -Wl,-z,relro,-z,now,-z,noexecstack -s -fPIE -pie")
set(WITH_HITRACE_SYSTRACE 1) # for other CMakeLists.txt files to use
add_compile_definitions(WITH_HITRACE_SYSTRACE)

add_subdirectory("${RNOH_CPP_DIR}" ./rn)

# RNOH_BEGIN: manual_package_linking_1
add_subdirectory("../../../../sample_package/src/main/cpp" ./sample-package)
+ add_subdirectory("${OH_MODULES}/@react-native-oh-tpl/react-native-hole-view/src/main/cpp" ./rnohkeys)
# RNOH_END: manual_package_linking_1

file(GLOB GENERATED_CPP_FILES "./generated/*.cpp")

add_library(rnoh_app SHARED
    ${GENERATED_CPP_FILES}
    "./PackageProvider.cpp"
    "${RNOH_CPP_DIR}/RNOHAppNapiBridge.cpp"
)
target_link_libraries(rnoh_app PUBLIC rnoh)

# RNOH_BEGIN: manual_package_linking_2
target_link_libraries(rnoh_app PUBLIC rnoh_sample_package)
+ target_link_libraries(rnoh_app PUBLIC rnoh_holeview)
# RNOH_END: manual_package_linking_2

Open entry/src/main/cpp/PackageProvider.cpp and add the following code:

#include "RNOH/PackageProvider.h"
#include "generated/RNOHGeneratedPackage.h"
#include "SamplePackage.h"
+ #include "HoleViewPackage.h"

using namespace rnoh;

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
        std::make_shared<RNOHGeneratedPackage>(ctx),
        std::make_shared<SamplePackage>(ctx),
+       std::make_shared<RNOHHoleViewPackage>(ctx),
    };
}

4. Running

Click the sync button in the upper right corner.

Alternatively, run the following instruction on the terminal:

cd entry
ohpm install

Then build and run the code.

Constraints

Compatibility

To use this repository, you need to use the correct React-Native and RNOH versions. In addition, you need to use DevEco Studio and the ROM on your phone.

Check the release version information in the release address of the third-party library: @react-native-oh-library/react-native-hole-view Releases

Properties

[!TIP] The Platform column indicates the platform where the properties are supported in the original third-party library.

[!TIP] If the value of HarmonyOS Support is yes, it means that the HarmonyOS platform supports this property; no means the opposite; partially means some capabilities of this property are supported. The usage method is the same on different platforms and the effect is the same as that of iOS or Android.

Name Description Type Required Platform HarmonyOS Support
Holes Hole Array Hole[] no iOS/Android yes
animation Hole update animation effect { duration: number, timingFunction: ERNHoleViewTimingFunction } no iOS/Android yes
onAnimationFinished Animation completion callback () => void no iOS/Android yes

Known Issues

  • Using C API OH_ArkUI_PointerEvent_SetStopPropagation to prevent the event from bubbling up causes scrollView out of control. This results in scrollView being able to scroll even outside the designated area: issue#1
