在settext编辑文本android后继续从编辑文本中删除char

Question

当按钮删除键盘持续为真时，如何在settext编辑文本后继续从编辑文本中删除字符？

edtDesc.addTextChangedListener(new TextWatcher() {

        String formatNumber = "";


        @Override
        public void afterTextChanged(Editable s) {
            edtDesc.setSelection(edtDesc.getText().length());

        }


        @Override
        public void beforeTextChanged(CharSequence s, int arg1, int arg2, int arg3) {

        }


        @Override
        public void onTextChanged(CharSequence s, int arg1, int arg2, int arg3) {
            if (s.length() != 0) {
                    edtDesc.setText(edtDesc.getText().toString().replace("A", "B"));
                    isSelectTozihat = true;
            }

        }

    });

感谢

    }


    @Override
    public void onTextChanged(CharSequence s, int arg1, int arg2, int arg3) {
        if ((s.length() != 0)&&(edtDesc.getText().toString().contains("A"))      {
edtDesc.setText(edtDesc.getText().toString().replace("A", "B"));
                isSelectTozihat = true;
