내 Button
과 다른 요소를 내 PopupWindow
에서 가져 오는 중, debugger
을 사용하여 null
으로보고하겠습니까?Android 팝업 창 팝업에서 요소를 가져 오지 못함
private void initiatePopupWindow()
{
try
{
// We need to get the instance of the LayoutInflater
LayoutInflater inflater = (LayoutInflater) LoginActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.activity_register,(ViewGroup)
findViewById(R.id.popup_element));
pwindo = new PopupWindow(layout, 600, 900, true);
pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);
btnReg = (Button) findViewById(R.id.btnReg);
inputName = (EditText) findViewById(R.id.name);
inputDOB = (DatePicker) findViewById(R.id.dob);
String name = inputName.getText().toString();
btnReg.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
if ( (!inputName.getText().toString().equals("")) &&
(getAge(inputDOB.getDayOfMonth(), inputDOB.getMonth(), inputDOB.getYear()) > 15))
{
//register user
}
else if ((inputName.getText().toString().equals("")))
{
Toast.makeText(getApplicationContext(),
"Please enter your name", Toast.LENGTH_SHORT).show();
}
else if ((getAge(inputDOB.getDayOfMonth(), inputDOB.getMonth(), inputDOB.getYear()) < 16))
{
Toast.makeText(getApplicationContext(),
"You must be at least 16 to use this app", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(getApplicationContext(), email, Toast.LENGTH_SHORT).show();
}
}
});
}
catch (Exception e)
{
e.printStackTrace();
}
}
사람이 올바른 방향으로 날 지점 또는 내가 그들을 R.id
를 사용하여 찾을 수없는 이유를 설명 할 수?
건배
