如何将React Native Android的默认文本颜色更改为黑色？

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="textColor">#000000</color>
</resources>

import android.os.Bundle;
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 {
    @Override
    protected String getMainComponentName() {
        return "YourAppName";
    }

    @Override
    protected ReactActivityDelegate createReactActivityDelegate() {
        return new ReactActivityDelegate(this, getMainComponentName()) {
            @Override
            protected ReactRootView createRootView() {
                return new RNGestureHandlerEnabledRootView(MainActivity.this);
            }
        };
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // 添加以下代码
        getWindow().getDecorView().setBackgroundColor(getResources().getColor(R.color.textColor));
    }
}
