我从 xml 文件创建一个片段，并在活动中的 setcontentview 方法中直接添加 xml 文件。如果我重新打开该片段导致强制关闭，它第一次工作正常。

xml：

<FrameLayout android:id="@+id/containner"
   android:layout_width="match_parent" android:layout_height="match_parent">
<fragment android:id="@+id/frag"
   android:name="com.pal.newloginscreenui.NavigationMenuFragment" 
   android:layout_width="match_parent"
   android:layout_height="match_parent"/> 
</FrameLayout>

我正在调用的弹出窗口

DoctorGlobal.pw = new PopupWindow(DashboardActivity.this);// create a popup window
    DoctorGlobal.pw.setTouchable(true);
    DoctorGlobal.pw.setFocusable(true);
    DoctorGlobal.pw.setOutsideTouchable(true);
    DoctorGlobal.pw.setTouchInterceptor(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {

            if (event.getAction() == MotionEvent.ACTION_OUTSIDE) { 
                DoctorGlobal.pw.dismiss();
                return true;
            }
            return false;
        }
    });

    int popWndwidth = (int)(width/4)*3;
    DoctorGlobal.pw
            .setWidth(popWndwidth);
    DoctorGlobal.pw
            .setHeight(android.view.ViewGroup.LayoutParams.MATCH_PARENT);
    View contentView = getLayoutInflater().inflate(R.layout.navg_menu, null);
    DoctorGlobal.pw.setContentView(contentView);
    container = (FrameLayout) contentView.findViewById(R.id.containner);
    DoctorGlobal.pw.showAsDropDown(v, 0, 0);

在navg_menu中具有上述xml代码

Answer 1

你的错误：

android.view.InflateException: Binary XML file line #7: Error inflating class fragment

  ....

Caused by: java.lang.IllegalArgumentException: Binary XML file line #7: 
Duplicate id 0x7f06004b, tag null, or parent id 0xffffffff with another 
fragment for com.pal.newloginscreenui.NavigationMenuFragment

你的 xml 标签：

<FrameLayout android:id="@+id/containner"
  ....                                      >
<fragment android:id="@+id/frag"
    android:name="com.pal.newloginscreenui.NavigationMenuFragment" 
  ....

你的java：

View contentView = getLayoutInflater().inflate(R.layout.navg_menu, null);

你有getLayoutInflater().inflate(R.layout.navg_menu, null);

它会出现navg_menu id 不存在或者它是您试图膨胀的菜单 xml，也许应该用于菜单并确保您有一个正确的 id 来创建您的 contentView。;

`MenuInflater inflater = getMenuInflater();`

`getMenuInflater().inflate`

或者您正在访问的 id 重复。 希望这会帮助您调试它。
