android EditText 使用

文本改变化要增加监听才能适时地返回文本数据，如代码，如果直接.getText().toString();是无法获得值的。

 

 

telNumText_send = (EditText) findViewById(R.id.telNumText_send);
        // 增加文本改变后监听
        telNumText_send.addTextChangedListener(new TextWatcher() {

                public void afterTextChanged(Editable s) {
                    // TODO Auto-generated method stub
                }

                public void beforeTextChanged(CharSequence s, int start, int count,
                        int after) {
                    // TODO Auto-generated method stub
                }

                public void onTextChanged(CharSequence s, int start, int before,
                        int count) {
                    // TODO Auto-generated method stub
                    // 得到电话
                   phone = telNumText_send.getText().toString();
                }
               
            });
