如何减少溅屏时间

Question

它需要7-10秒，我想知道有一个方法可以减少时间。在安装启动屏幕之前，主页将在2-3秒内加载。我已经安装了react-native-splash-screen软件包，并使用@bam.tech/react-native-make自动配置了安卓文件。

如果你想知道的话，从没试过真正的设备。

MainActivity.java

package com.myApp;

import android.os.Bundle;
import org.devio.rn.splashscreen.SplashScreen;
import com.facebook.react.ReactActivity;

public class MainActivity extends ReactActivity {

  /**
   * Returns the name of the main component registered from JavaScript. This is used to schedule
   * rendering of the component.
   */
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      SplashScreen.show(this, R.style.SplashScreenTheme);
      super.onCreate(savedInstanceState);
  }

  @Override
  protected String getMainComponentName() {
    return "myApp";
  }
}

AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.myApp">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:allowBackup="false"
      android:theme="@style/AppTheme">
        <activity
          android:name=".MainActivity"
          android:label="@string/app_name"
          android:configChanges="keyboard|keyboardHidden|orientation|screenSize|uiMode"
          android:launchMode="singleTask"
          android:windowSoftInputMode="adjustResize">
          <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
          </intent-filter>
        </activity>
      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
    </application>

</manifest>

splashscreen.xml

                android:src="@drawable/splash_image" />

        <item name="android:statusBarColor">@color/app_bg</item>
    </style>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:textColor">#000000</item>

        <!-- Add the following line to set the default status bar color for all the app. -->
        <item name="android:statusBarColor">@color/app_bg</item>
        <!-- Add the following line to set the default status bar text color for all the app 
        to be a light color (false) or a dark color (true) -->
        <item name="android:windowLightStatusBar">false</item>
        <!-- Add the following line to set the default background color for all the app. -->
        <item name="android:windowBackground">@color/app_bg</item>
    </style>

Answer 1

尝试在Style.xml中添加以下内容

<item name="android:windowDisablePreview">true</item>

这将删除开始时出现的白色屏幕。
