java - 安卓 : Issue in back from a pop up window

Question

我使用以下代码在 fragment 的弹出窗口中创建饼图。

mChartView = ChartFactory.getPieChartView(getActivity(), distributionSeries, defaultRenderer);
    popupWindow = new PopupWindow(mChartView, LayoutParams.FILL_PARENT,  
                                 LayoutParams.FILL_PARENT, false);
                        popupWindow.setOutsideTouchable(true);
                        popupWindow.showAsDropDown(mChartView, 50, 50);
                        popupWindow.setTouchInterceptor(new OnTouchListener() {

                            @Override
                            public boolean onTouch(View v, MotionEvent event) {
                                // TODO Auto-generated method stub
                                if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
                                    popupWindow.dismiss();

                                }
                                return false;
                            }
                        });

这是我的完整代码。

这是我的新代码。

private static boolean isChart = false;

popupWindow = new PopupWindow(mChartView, LayoutParams.MATCH_PARENT,  
                                LayoutParams.MATCH_PARENT, false);
                        popupWindow.setOutsideTouchable(true);
                        popupWindow.showAsDropDown(mChartView, 50, 50);
                        isChart = true;

@Override
public void onBackPressed() {
    System.out.println("BACKED");
    if(isChart) {
         popupWindow.dismiss();  
    } else {  
         super.onBackPressed();
    }
    //return;
}

它显示了图表。但当我按下 Android 中的后退按钮时，它不会从饼图窗口返回。我该如何解决这个问题？任何建议都将受到高度赞赏。

您需要添加以下内容:

popupWindow.setBackgroundDrawable(new BitmapDrawable());

在创建弹出窗口时，否则由于未设置背景可绘制，它将不会对任何触摸事件使用react。
