如何在安卓中添加MainActivity.java文件中的代码

Question

我使用的是react native包，在文档中我需要将其添加到MainActivity.java文件中

import android.os.Bundle; // here
import com.facebook.react.ReactActivity;
// react-native-splash-screen >= 0.3.1
import org.devio.rn.splashscreen.SplashScreen; // here
// react-native-splash-screen < 0.3.1
import com.cboy.rn.splashscreen.SplashScreen; // here

public class MainActivity extends ReactActivity {
   @Override
    protected void onCreate(Bundle savedInstanceState) {
        SplashScreen.show(this);  // here
        super.onCreate(savedInstanceState);
    }
    // ...other code
}

但是我的问题是我的MainActivity.java文件是不同的，这是我的MainActivity.java文件，

package myApp.tasawk.com;

import com.facebook.react.ReactActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;
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 String getMainComponentName() {
    return "myApp";
  }
  @Override
  protected ReactActivityDelegate createReactActivityDelegate() {
    return new ReactActivityDelegate(this, getMainComponentName()) {
      @Override
      protected ReactRootView createRootView() {
       return new RNGestureHandlerEnabledRootView(MainActivity.this);
      }
    };
  }
}

我想在我的MainActivity.java中添加这些行，我应该在哪里编写代码，我想在这里添加这一部分，

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        SplashScreen.show(this);  // here
        super.onCreate(savedInstanceState);
    }

但是当我添加它时，构建失败了

我认为你有一个更老的react native版本，但我认为你可以试试这个：

package myApp.tasawk.com;

import com.facebook.react.ReactActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;
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 String getMainComponentName() {
    return "myApp";
  }
  @Override
  protected ReactActivityDelegate createReactActivityDelegate() {
    return new ReactActivityDelegate(this, getMainComponentName()) {
      @Override
      protected ReactRootView createRootView() {
       return new RNGestureHandlerEnabledRootView(MainActivity.this);
      }
    };
  }
  @Override
  protected void onCreate(Bundle savedInstanceState) {
        SplashScreen.show(this);  // here
        super.onCreate(savedInstanceState);
  }
}
