react-native-text-gradient
[!TIP] Github address
Find the matching version information in the release address of a third-party library: @react-native-oh-tpl/react-native-text-gradient 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 install @react-native-oh-tpl/react-native-text-gradient
yarn add @react-native-oh-tpl/react-native-text-gradient
The following code shows the basic use scenario of the repository:
[!WARNING] The name of the imported repository remains unchanged.
import React from 'react';
import {StyleSheet, Text, View } from 'react-native';
import { LinearTextGradient } from 'react-native-text-gradient';
const TextGradientTest = () => {
return (
<View style={styles.container}>
<LinearTextGradient
style={styles.welcome}
locations={[0, 1]}
colors={['blue', 'red']}
start={{ x: 0, y: 0 }}
end={{ x: 1, y: 0 }}
>Welcome to React Native!
</LinearTextGradient>
<Text style={styles.instructions}>To get started, edit App.js</Text>
<Text style={styles.instructions}>{'Double tap R on your keyboard to reload,\n' +
'Shake or press menu button for dev menu'}</Text>
</View>
);
}
export default TextGradientTest;
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#ffffff',
marginTop: 100
},
welcome: {
fontSize: 20,
width: 'auto',
height: 'auto',
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
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.
{
...
"overrides": {
"@rnoh/react-native-openharmony" : "./react_native_openharmony"
}
}
Currently, two methods are available:
Method 1 (recommended): Use the HAR file.
[!TIP] The HAR file is stored in the
harmonydirectory 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-text-gradient": "file:../../node_modules/@react-native-oh-tpl/react-native-text-gradient/harmony/text_gradient.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.
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-text-gradient/src/main/cpp" ./text_gradient)
# 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_text_gradient)
# 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 "LinearTextGradientPackage.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<LinearTextGradientPackage>(ctx),
};
}
Open the entry/src/main/ets/RNPackagesFactory.ts file and add the following code:
...
+ import {LinearTextGradientPackage} from '@react-native-oh-tpl/react-native-text-gradient/ts';
export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
return [
new SamplePackage(ctx),
+ new LinearTextGradientPackage(ctx)
];
}
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.
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-tpl/react-native-text-gradient Releases
[!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 |
|---|---|---|---|---|---|
| start | Coordinates declare the position that the gradient starts at, as a fraction of the overall size of the gradient, starting from the top left corner. | number | yes | iOS/Android | yes |
| end | Same as start, but for the end of the gradient. | number | yes | iOS/Android | yes |
| loactions | An optional array of numbers defining the location of each gradient color stop, mapping to the color with the same index in prop. | number[] | yes | iOS/Android | yes |
| colors | An array of at least two color values that represent gradient colors. | string | yes | iOS/Android | yes |
| useViewFrame | Optional. If true gradient will be calculated for text view background frame rather than text frame. | boolean | yes | iOS/Android | no |
| useGlobalCache | accessing or managing a cache that is available globally throughout the application. | boolean | yes | iOS | no |
