react-native 打开设置界面

react

iOS

iOS打开设置还是比较简单的,使用Linking组件即可:

Linking.openURL('app-settings:')

.catch(err => console.log('error', err))

Android

1、在android/app/src/main/java/com/<projectname>/文件夹下创建opensettings文件夹

2、在这个文件夹下创建模块文件OpenSettingsModule.java(模块功能)和包文件OpenSettingsPackage.java(注册我们的模块)。

3、在OpenSettingsModule.java文件中,填入如下代码:

package com.<projectname>.opensettings; // 记得把<projectname>改为你的项目名称

import android.app.Activity;

import android.content.Intent;

import com.facebook.react.bridge.Callback;

import com.facebook.react.bridge.ReactApplicationContext;

import com.facebook.react.bridge.ReactMethod;

import com.facebook.react.bridge.ReactContextBaseJavaModule;

public class OpenSettingsModule extends ReactContextBaseJavaModule {

@Override

public String getName() {

/**

* return the string name of the NativeModule which represents this class in JavaScript

* In JS access this module through React.NativeModules.OpenSettings

*/

return "OpenSettings";

}

@ReactMethod

public void openNetworkSettings(Callback cb) {

Activity currentActivity = getCurrentActivity();

if (currentActivity == null) {

cb.invoke(false);

return;

}

try {

currentActivity.startActivity(new Intent(android.provider.Settings.ACTION_SETTINGS));

cb.invoke(true);

} catch (Exception e) {

cb.invoke(e.getMessage());

}

}

/* constructor */

public OpenSettingsModule(ReactApplicationContext reactContext) {

super(reactContext);

}

}

4、上面的模块功能可以通过调用openNetworkSettings函数打开android设置。现在我们需要注册这个模块。在OpenSettingsPackage.java里填入如下代码:

package com.<projectname>.opensettings; // 记得把<projectname>改为你的项目名称

import com.facebook.react.ReactPackage;

import com.facebook.react.bridge.JavaScriptModule;

import com.facebook.react.bridge.NativeModule;

import com.facebook.react.bridge.ReactApplicationContext;

import com.facebook.react.uimanager.ViewManager;

import java.util.ArrayList;

import java.util.Collections;

import java.util.List;

public class OpenSettingsPackage implements ReactPackage {

@Override

public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) {

List<NativeModule> modules = new ArrayList<>();

modules.add(new OpenSettingsModule(reactContext));

return modules;

}

// @Override

// public List<<Class>? extends JavaScriptModule> createJSModules() {

// return Collections.emptyList();

// }

@Override

public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) {

return Collections.emptyList();

}

}

5、把包提供到MainApplication.java文件的getPackages方法中:

import com.<projectname>.opensettings.*; // 还是要修改成自己项目名

...

@Override

protected List<ReactPackage> getPackages() {

return Arrays.<ReactPackage>asList(

new MainReactPackage(),

new OpenSettingsPackage() /* <---- add here */

);

}

6、准备工作完成,接下来调用:

import { NativeModules } from 'react-native'

export default class App extends Component {

constructor(props) {

super(props)

}

openSettings() {

NativeModules.OpenSettings.openNetworkSettings(data => {

console.log('call back data', data)

})

}

render() {

return (

<View style={styles.container}>

<Text onPress={this.openSettings}>Open Android Settings</Text>

</View>

)

}

}

这回能开心的打开设置咯~
