MainActivity中弹出窗口中的AutoCompleteTextView

Question

在MainActivity中，我弹出带有AutoCompleteTextView的窗口，它可以正常工作。 我什至可以为此做一些工作（egtextView.setText（“ New”））。 但是我担心适配器，因为单击TextView之后没有任何反应（没有列表和键盘）。

我认为这个问题符合要求：

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。 我不知道该放什么。 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);
    }

您需要使PopupWindow焦点。 若要使AutoCompleteTextView立即打开键盘，请将PopupWindow的SoftInputMode设置为SOFT_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);
    }
