如何在android的MainActivity.java文件中添加代码

Question

我使用的是react native包，在docs中我需要在MainActivity.java文件中添加它，

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，这里是我的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，我应该在哪里写我的代码，我想在这里添加那部分，

@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

我想你有一个旧版本的react native，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);
}
}
