              if(m != null)
              {
                // m.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
                m.toggleSoftInput(0, InputMethodManager.SHOW_IMPLICIT);
              } 
         }

    }, 100);

Here is my solution to this problem:

Put a dummy edit text, and set it’s visibility to GONE, and add it to a containing LinearLayout, after adding the WebView to the layout.

Example:

AlertDialog.Builder builder = new AlertDialog.Builder(this);

LinearLayout wrapper = new LinearLayout(this);
WebView webView = new WebView(this);
EditText keyboardHack = new EditText(this);

keyboardHack.setVisibility(View.GONE);

webView.loadUrl(url);

wrapper.setOrientation(LinearLayout.VERTICAL);
wrapper.addView(webView, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
wrapper.addView(keyboardHack, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);              

builder.setView(wrapper);

builder.create().show();

Once this is done, everything should work properly, and when you select an item in the WebView, the keyboard appears as expected.
