下面是我的xml代码
<com.google.android.material.textfield.TextInputLayout
android:id="@+id/til_email"
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="10dp"
android:layout_marginLeft="10dp"
android:layout_marginTop="5dp"
android:layout_marginEnd="10dp"
android:layout_marginRight="10dp"
android:layout_marginBottom="5dp"
android:paddingStart="10dp"
android:paddingTop="5dp"
android:paddingEnd="10dp"
android:paddingBottom="5dp"
app:endIconMode="custom"
app:endIconDrawable="@drawable/ic_calendar"
app:endIconTint="@color/primaryDarkColor">
<com.google.android.material.textfield.TextInputEditText
android:id="@+id/et_email"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Enter email"
android:textSize="15sp" >
<com.google.android.material.chip.ChipGroup
android:id="@+id/cg_email"
android:layout_width="0dp"
android:layout_height="wrap_content">
</com.google.android.material.chip.ChipGroup>
</com.google.android.material.textfield.TextInputEditText>
