MainActivity 弹出窗口中的 AutoCompleteTextView

Question

在 MainActivity 中，我有带有 AutoCompleteTextView 的弹出窗口并且它可以工作。我什至可以用它做一些工作人员 (egtextView.setText("New"))。但我担心适配器，因为单击 TextView 后没有任何反应（没有列表和键盘）。我认为这个问题是一致的：ArrayAdapter<String> adapter = new ArrayAdapter <String (customView.getContext(),android.R.layout.simple_dropdown_item_1line, countryNameList);特别是在第一个参数 - 上下文中。我不知道我应该把什么放在那里。我的代码：public void steptwo() {        LayoutInflater inflater = (LayoutInflater) context.getSystemService(LAYOUT_INFLATER_SERVICE);        View customView = inflater.inflate(R.layout.popup_observedproperty,null);        mPopupWindow = new PopupWindow(                customView,                LayoutParams.WRAP_CONTENT,                LayoutParams.WRAP_CONTENT        );        String[] countryNameList = {"India", "China", "Australia", "New Zealand", "England", "Pakistan"};        ArrayAdapter<String> adapter = new ArrayAdapter<String>(customView.getContext(),                android.R.layout.simple_dropdown_item_1line, countryNameList);        AutoCompleteTextView textView = (AutoCompleteTextView) customView.findViewById(R.id.autoCompleteTextView);        textView.setText("New");        textView.setAdapter(adapter);        if(Build.VERSION.SDK_INT>=21){            mPopupWindow.setElevation(5.0f);        }        mPopupWindow.showAtLocation(mRelativeLayout, Gravity.CENTER,0,0);    }

Answer 1

您需要使焦点可PopupWindow聚焦。要允许AutoCompleteTextView立即打开键盘，请将设置SoftInputMode为。PopupWindowSOFT_INPUT_STATE_ALWAYS_VISIBLE

public void steptwo() {

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(LAYOUT_INFLATER_SERVICE);

        View customView = inflater.inflate(R.layout.popup_observedproperty,null);

        mPopupWindow = new PopupWindow(

                customView,

                LayoutParams.WRAP_CONTENT,

                LayoutParams.WRAP_CONTENT

        );

        String[] countryNameList = {"India", "China", "Australia", "New Zealand", "England", "Pakistan"};

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(customView.getContext(),

                android.R.layout.simple_dropdown_item_1line, countryNameList);

        AutoCompleteTextView textView = (AutoCompleteTextView) customView.findViewById(R.id.autoCompleteTextView);

        textView.setText("New");

        textView.setAdapter(adapter);

        textView.setThreshold(1);

        if(Build.VERSION.SDK_INT>=21){

            mPopupWindow.setElevation(5.0f);

        }

        mPopupWindow.setFocusable(true);

        mPopupWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

        mPopupWindow.showAtLocation(mRelativeLayout, Gravity.CENTER,0,0);

    }
