Question

我有一个在线性布局中的编辑文本。线性布局位于弹出窗口内。

当我运行应用程序时，我无法单击并输入编辑文本的输入。

弹出窗口的代码，它位于我片段的onCreateView中：

final Button makeoffer = (Button) view.findViewById(R.id.make_offer);
    makeoffer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            LayoutInflater layoutInflater = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View popupView = layoutInflater.inflate(R.layout.offer_popup, null);
            final PopupWindow popupWindow = new PopupWindow(popupView,LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
            EditText mEditText = (EditText) popupView.findViewById(R.id.payment_field);
            popupView.clearFocus();
            mEditText.requestFocus();
            popupWindow.setFocusable(true);
            popupWindow.update();

            final Spinner spinner1 = (Spinner) popupView.findViewById(R.id.transaction_spinner);
            spinner1.setAdapter(new ArrayAdapter<CharSequence>(getActivity(), R.layout.support_simple_spinner_dropdown_item,getActivity().getResources().getTextArray(R.array.payment_list)));

            Button btnDismiss = (Button)popupView.findViewById(R.id.cancel2);
            btnDismiss.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    popupWindow.dismiss();
                }
            });
            popupWindow.showAtLocation(popupView, Gravity.NO_GRAVITY, 0, 0);
        }
    });

弹出窗口布局的XML代码：

对于其他读这篇文章的人：

非常感谢@AnkiiRawat。我做的是我摆脱了android：descendantFocusability =＆＃34; blocksDescendants＆＃34;在xml文件中。在包含EditText的LinearLayout中我添加了机器人：descendantFocusability =＆＃34; afterDescendants＆＃34;属性。

无法在线性布局内部，弹出窗口内单击edittext
