Android Webview Strategy For Deleting Images Causing Speech-To-Text to Fail

问题

Problem: Can't delete image in contenteditable div on Android

Only known solution at the moment: Android: Backspace in WebView/BaseInputConnection

Problem with solution: Setting: creating a BaseInputConnection using the regular constructor seems to disable speech to text from functioning correctly. as opposed to using WebView.onCreateInputConnection(EditorInfo) to generate an InputConnection.

any ideas how to remedy this?

I had the same issue also with text completion using SwiftKey. In order to fix it you must remember some things:

• you must extend BaseInputConnection and wrap the original webview's InputConnection
• don't use InputConnectionWrapper as it will cause other problems

• you need to subclass a second method: commitText

  public boolean commitText(CharSequence text, int newCursorPosition) {
  
      if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
          return orig.commitText(text, newCursorPosition);
  
      } else {
          // pre-kitkat workaround 
          boolean res = true;
          for (int i = 0; i < text.length(); i++) {
              res = orig.commitText(text.subSequence(i, i+1), newCursorPosition);
          }
          return res;
      }
  }
