我们可以编写一段监听器，当tab关闭时触发该监听器，强制将焦点移回到Android Studio窗口。

以下是具体代码示例：

import com.intellij.openapi.actionSystem.DataContext;
import com.intellij.openapi.actionSystem.DataKeys;
import com.intellij.openapi.actionSystem.impl.SimpleDataContext;
import com.intellij.openapi.actionSystem.impl.Utils;
import com.intellij.openapi.keymap.KeymapUtil;
import com.intellij.openapi.util.SystemInfo;
import com.intellij.openapi.wm.IdeFocusManager;
import com.intellij.openapi.wm.WindowManager;
import com.intellij.ui.tabs.JBTabs;
import com.intellij.ui.tabs.impl.JBTabsImpl;
import com.intellij.util.ui.UIUtil;

import javax.swing.*;
import java.awt.*;

public class FocusFixAction {

    public static void install() {
        JBTabsImpl tabs = UIUtil.uiTraverser(WindowManager.getInstance().getIdeFrame(null).getComponent())
                .getNext(JBTabsImpl.class);
        tabs.addListener(new FocusFixListener());
    }

    private static class FocusFixListener extends JBTabs.Listener.Adapter {
        @Override
        public void tabRemoved(TabInfo info) {
            JComponent c = info.getComponent();
            if (c == null) return;

            if (c.getParent() instanceof JLayeredPane) {
                c = c.getParent();
            }

            Rectangle cBounds = c.getBounds();

            cBounds.y += 2;
            if (SystemInfo.isOSX) {
                // move down one more pixel to work around window manager bugs on macOS
                cBounds.y += 1;
            }

            IdeFrame frame = IdeFrame.getActiveFrame();
            if (frame == null) return;

            JLayeredPane rootPane = frame.getRootPane();
            if (rootPane == null) return;

            JComponent focusOwner = (JComponent) KeyboardFocusManager.getCurrentKeyboardFocusManager().getFocusOwner();
            boolean isToolbar = c instanceof ActionToolbarImpl;

            // if the current focused component is the main editor, focus the project tree view instead.
            if (isToolbar || focusOwner == null || Utils.getComponentParent(focusOwner, JBTabs.class) == null) {
                DataContext dataContext;
                if (isToolbar) {
                    dataContext = new SimpleDataContext(DataKeys.PROJECT.getName(), null, DataKeys.CONTEXT_COMPONENT.getName(), c);
                } else {
                    dataContext = DataManager.getInstance().getDataContext(rootPane);
                }

                ProjectView view = LangDataKeys.PROJECT_VIEW.getData(dataContext);

                if (view != null) {
                    view.select(null, null, false);
                    IdeFocusManager.getGlobalInstance().doWhenFocusSettlesDown(() -> view.select(null, info.getProject(), true));
