先来看下常用手机分辨率
// mdpi 480*320
// hdpi 800*480
// xhdpi 1280*720
// xhdpi 1920*1080
修改APP名称
找到android/app/src/main/AndroidManifest.xml
<application
android:name=".MainApplication"
android:label="@string/app_name"
android:icon="@mipmap/ic_launcher"
android:allowBackup="false"
android:theme="@style/AppTheme">
</application>
找到 android:label = "@string/app_name"。这个对应的就是APP的名称
进入:android/app/src/main/res/valuse/strings.xml目录下
<resources>
<string name="app_name">APP名称</string>
</resources>
修改APP图标
1、找到读取APP图标的地方
进入目录::android/app/src/main/AndroidManifest.xml
<application
android:name=".MainApplication"
android:label="@string/app_name"
android:icon="@mipmap/ic_launcher"
android:allowBackup="false"
android:theme="@style/AppTheme">
</application>
可以看到,icon是在mipmap文件下的ic_launcher图片,因此,在android/app/src/main/res下新建mipmap_hdpi, mipmap_mdpi, mipmap_xhdpi,mipmap_xxhdpi文件,里面分别存放图片ic_launcher,
分辨率分别为72x72, 48x48, 96x96, 144x144,192*192
修改Splash
附上地址:https://github.com/crazycodeboy/react-native-splash-screen
安装
npm install react-native-splash-screen --save
react-native link react-native-splash-screen
检查 link
settings.gradle
include ‘:react-native-splash-screen‘
project(‘:react-native-splash-screen‘).projectDir = new File(rootProject.projectDir, ‘../node_modules/react-native-splash-screen/android‘)
build.gradle
compile project(‘:react-native-splash-screen‘)
MainApplication.java
import org.devio.rn.splashscreen.SplashScreenReactPackage;
new SplashScreenReactPackage()
启动页设置
在android/app/src/main/res下新建layout文件,launch_screen.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/launch_screen">
</LinearLayout>
MainActivity.java
import android.os.Bundle;
import org.devio.rn.splashscreen.SplashScreen;
protected void onCreate(Bundle savedInstanceState) {
SplashScreen.show(this); // <--添加这一句
super.onCreate(savedInstanceState);
}
在android/app/src/main/res下新建drawable_hdpi, drawable_mdpi, drawable_xhdpi,drawable_xxhdpi文件,里面分别存放图片launch_screen,
分辨率分别为文章开头提到的分辨率,
在你首个页面增加
import SplashScreen from ‘react-native-splash-screen‘;
componentDidMount() {
SplashScreen.hide(); //关闭启动屏幕
}
至此,整个启动页完成了
