Now where is this error coming from? I found "We already have an EditText, can only have one" here, but don't know how to handle it.
Notice: I'm getting the same errror if I use the .xml for adding EditTexts.
Here are some sources I used:
Implement Text Input Layout Using Android Design Support Library
Design Support Library v22.2.0について Part 1
The TextInputLayout
is used to handle the behaviour of the hint an how it is shown for an EditText. So I assume that it is only possible to add one EditText
to a TextInputLayout
.
A simple solution might be:
Add more TextInputLayout
's to your xml and use them in your code like:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.design.widget.TextInputLayout
android:id="@+id/login_form_layout_username"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.design.widget.TextInputLayout>
<android.support.design.widget.TextInputLayout
android:id="@+id/login_form_layout_pw"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.design.widget.TextInputLayout>
(...)
</LinearLayout>
LinearLayout is used to align each item below the previous.
And in your class:
TextInputLayout layout_username = (TextInputLayout) findViewById(R.id.login_form_layout_username);
TextInputLayout layout_pw = (TextInputLayout) findViewById(R.id.login_form_layout_pw);
(...)
layout_username.addView(s2_username, ...);
layout_pw.addView(s2_pw, ...);
