Vivo the DEL key on the phone the reason for Onkeylistener not responding and the solution _ios

Use a custom input box in the Modify Transaction password interface

Like this (forgive the ugly point ~)

Results yesterday there is user feedback on the Vivo mobile phone, del key Invalid problem ~ ~ ~ ~

The final discovery was: EdiText的OnKeyListener no response.

Finally searched and found the solution: EdiTextView的InputConnectionWrapper The overridden method solves the problem:

The code is as follows:

public class Zanyedittext extends EditText {private Ondelkeyeventlistener delkeyeventlistener;
  Public Zanyedittext (context, AttributeSet attrs, int defstyle) {Super (context, attrs, Defstyle);
  Public Zanyedittext (context, AttributeSet attrs) {Super (context, attrs);
  Public Zanyedittext {Super (context); @Override public inputconnection oncreateinputconnection (Editorinfo outattrs) {return new zanyinputconnection (s
  Uper.oncreateinputconnection (Outattrs), true); Private class Zanyinputconnection extends Inputconnectionwrapper {public zanyinputconnection (inputconnection Targ
    ET, boolean mutable) {super (target, mutable);
          @Override public boolean sendkeyevent (KeyEvent event) {if event.getaction () = = Keyevent.action_down && Event.getkeycode () = = Keyevent.keycode_del) {if (Delkeyeventlistener!= null) {Delkey Eventlistener.ondeleteclick ();
        return true;
    } return Super.sendkeyevent (event); @Override public boolean deletesurroundingtext (int beforelength, int afterlength) {if (Beforelength = 1 && Afterlength = = 0) {return sendkeyevent (new KeyEvent (Keyevent.action_down, Keyevent.keycode
      _del)) && sendkeyevent (New KeyEvent (KEYEVENT.ACTION_UP, Keyevent.keycode_del));
    Return Super.deletesurroundingtext (Beforelength, afterlength);  }/** * * Feature Description: <br> *〈 Feature detailed description 〉* * @param delkeyeventlistener EditText Delete callback/public void
  Setdelkeyeventlistener (Ondelkeyeventlistener delkeyeventlistener) {this.delkeyeventlistener = DelKeyEventListener;
  public interface Ondelkeyeventlistener {void Ondeleteclick (); }
}
