反应本机检查平板电脑或屏幕是否以英寸为单位 [英] React native check if tablet or screen in inches

问题描述

我为平板电脑和移动设备建立了不同的渲染逻辑.我想知道是否有一种方法以英寸为单位获取屏幕尺寸，或者甚至没有任何模块可以自动检测设备是否为平板电脑.

I've established a different render logic for tablets and mobile devices. I was wondering if there is a way to get the screen size in inches or maybe even any module to automatically detect if the device is a tablet or not.

我之所以没有直接使用Dimensions API来获取屏幕分辨率，是因为有许多Android平板电脑的分辨率低于许多移动平板电脑.

The reason I am not using the dimensions api directly to get the screen resolution is that there are many android tablets with lower resolution than many of their mobile counterparts.

谢谢.

推荐答案

基于@martinarroyo的答案，一种使用

Based on @martinarroyo's answer, a way to go about it use the react-native-device-info package.

但是android实现基于屏幕分辨率.这可能是一个问题，因为许多平板电脑设备的分辨率低于许多移动设备，这可能会引起问题.

However the android implementation is based on screen resolution. That can be a problem as there are many tablet devices with a lower resolution than many mobile devices and this can cause problems.

我将使用并建议的解决方案是使用 react-native-device-info对于苹果设备和android设备，使用以下类型的简单比例逻辑:

The solution I will be using and am suggesting is use react-native-device-info for apple devices and for android devices go with a simple ratio logic of the type:

function isTabletBasedOnRatio(ratio){

if(ratio > 1.6){
    return false;
}else{
    return true;
}

}

这不是一个完美的解决方案，但是有许多具有类似手机比率甚至平板手机的小型平板电脑(Android还是模糊的)，并且这种解决方案也适用于那些平板电脑.

This is not a perfect solution but there are many small tablets with phonelike ratios as well or even phablets ( android is blurry) and this solutions is inclusive towards those as well.
