使用按钮和菜单项调用相同的片段（无需在 backStack 中创建重复项）

Question

我正在创建一个应用程序，该应用程序有一个抽屉一个 MainActivity 和许多片段，其中一个片段将所有按钮保存到其他片段（不包括它自己），所以buttonFragment 和抽屉现在都可以调用片段问题是当我从抽屉调用它时，我创建每个片段的两个副本，当我从buttonsFragment调用它时

我的代码：

MainActivity()

 @SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.

    int id = item.getItemId();
    xFragment xFrag = new xfragment();

    if (id == R.id.menuItem1) {

        FragmentManager manager = getSupportFragmentManager();
        android.support.v4.app.FragmentTransaction fM =     manager.beginTransaction();

        boolean moneyFragmentPoppedMenu = manager.popBackStackImmediate(xFragName,0);




        if(!FragmentPoppedMenu){

            fM.replace(R.id.content_main, xfrag, mT);
            fM.addToBackStack(mFragName);
            fM.commit();
        }

       else if (FragmentPoppedMenu){

        fM.replace(R.id.content_main, xfrag);}


    }

buttonsFragment()

xFragButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            FragmentManager manager = getActivity().getSupportFragmentManager();

            android.support.v4.app.FragmentTransaction fM = manager.beginTransaction();
            boolean FragmentPoppedButton = manager.popBackStackImmediate(xFragName, 0 );


            if(!FragmentPoppedButton){
                fM.replace(R.id.content_main, xfrag);
                fM.addToBackStack(xFragName);
                fM.commit();
            }

         else  if (FragmentPoppedButton){ fM.replace(R.id.content_main, xfrag);}

我发现，因为当我从菜单打开并在 editText 中输入内容然后从buttonsFragment 打开时，它会显示一个清晰的editText，然后当我从菜单再次打开时，我输入的内容仍然存在

@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.

int id = item.getItemId();
xFragment xFrag = new xfragment();

if (id == R.id.menuItem1) {
         xFragButton.performClick();

}

按钮片段：

onCreateView(){

Button xFragButton = (Button) v.findViewById(R.id.Button1);

xFragButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        FragmentManager manager = getSupportFragmentManager();
    android.support.v4.app.FragmentTransaction fM =     manager.beginTransaction();

    boolean moneyFragmentPoppedMenu = manager.popBackStackImmediate(xFragName,0);




    if(!FragmentPoppedMenu){

        fM.replace(R.id.content_main, xfrag, mT);
        fM.addToBackStack(mFragName);
        fM.commit();
    }

   else if (FragmentPoppedMenu){

    fM.replace(R.id.content_main, xfrag);
   }
