所以我在 PopupWindow 中有 EditText 输入,我试图通过使用一些检查来验证这个字段,然后使用 setError 方法设置错误。我得到了以上错误:/知道有什么问题吗?
final float scale = context.getResources().getDisplayMetrics().density;
int popupWidth = (int) (300 * scale + 0.5f);
int popupHeight = (int) (345 * scale + 0.5f);
LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.popupreg);
LayoutInflater layoutInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layout = layoutInflater.inflate(R.layout.logregpopup, viewGroup);
popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(popupWidth);
popup.setHeight(popupHeight);
popup.setFocusable(true);
popup.setBackgroundDrawable(new BitmapDrawable());
popup.showAtLocation(layout, Gravity.BOTTOM,0,90);
Button btnreg = (Button) layout.findViewById(R.id.btnregister);
btnreg.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
progressDialog = ProgressDialog.show(context, "Ładowanie", "poczekaj proszę !");
getmethod = 1;
int err = 0;
TextHelper thelper = new TextHelper();
EditText login = (EditText) layout.findViewById(R.id.reglogin);
EditText email = (EditText) layout.findViewById(R.id.regemail);
EditText pass1 = (EditText) layout.findViewById(R.id.regpass1);
EditText pass2 = (EditText) layout.findViewById(R.id.regpass2);
String l = login.getText().toString();
String e = email.getText().toString();
String p1 = pass1.getText().toString();
String p2 = pass2.getText().toString();
if(l.equals("") || l.length() < 3){
err++;
login.setError("Login musi mieć co najmniej 3 znaki");
}
我可以毫无问题地从登录字段中获取文本,所以这只是 setError 的问题。
