为什么用WebView扩充布局时看不到软键盘？

Question

I have a donation option on my app in the menu. When the user taps on that an AlertDialog.Builder appears that will display a layout with a webviewer on it. The page loads just fine in the WebViewer in the AlertDialog. However, when the webpage loads and there is a editable text view on the webpage the keyboard will not popup to allow users to enter in their dollar amount. Here is what I tried...

AlertDialog.Builder adb = new AlertDialog.Builder(MainActivity.this);
            adb.setIcon(R.drawable.ic_baseline_payment_32);
            adb.setTitle("Tip Developer");

            View v = getLayoutInflater().inflate(R.layout.tip_developer_layout, null);
            WebView wv = v.findViewById(R.id.tip_donation_webViewer);
            WebSettings ws = wv.getSettings();
            ws.setJavaScriptEnabled(true);

            wv.loadUrl("");

            wv.setWebViewClient(new WebViewClient() {

                public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

                }

                public void onPageFinished(WebView view, String url) {
                    wv.requestFocusFromTouch();
                    wv.requestFocus(View.FOCUS_DOWN);
                }
            });

            wv.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View view, MotionEvent motionEvent) {
                    switch (motionEvent.getAction())
                    {
                        case MotionEvent.ACTION_DOWN:
                        case MotionEvent.ACTION_UP:
                            if (!v.hasFocus())
                            {
                                v.requestFocus();
                            }
                            break;
                    }
                    return false;
                }
            });


            adb.setPositiveButton("Close", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {

                }
            });

            adb.setView(v);
            adb.create();
            adb.show();

I appreciate the help!

Insert this code.

private void showSoftKeyBoard() {
        InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    }

Then, implement it in OnCLick .

wv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showSoftKeyBoard();
            }
        });

Add this line in your EditText.

android:inputType="number"

And insert this code.

@Override
    public void onResume() {
        super.onResume();
        wv.setFocusableInTouchMode(true);
        wv.requestFocus();
    }
