如果在编辑文本中是自动的下一个活动是任何文本

Question

我有编辑文本的问题。我想如果编辑文本是六个字符转到下一个actitvity。我写这段代码，但如果写六个字符不进行下一个活动。

这是我的代码

smsCode.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                if (s.toString().trim().length()== 6){

                    Intent intent = new Intent(SmsCodeActivity.this,ScanQrCodeActivity.class);
                    startActivity(intent);
                }

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {

            }
    });

smsCode.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                    if(smsCode.getText().toString().trim().length()== 6){
                    Intent intent = new Intent(SmsCodeActivity.this,ScanQrCodeActivity.class);
                    startActivity(intent);
                }
            }

            @Override
            public void afterTextChanged(Editable s) {
            }
    });

Answer 2

尝试在onTextChanged

中完成工作

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {

if (smsCode.getText().toString().trim().length()== 6){

                Intent intent = new Intent(SmsCodeActivity.this,ScanQrCodeActivity.class);
                startActivity(intent);
            }
        }
