当我在模拟器上启动应用程序时,我得到
java.lang.RuntimeException:无法启动活动组件信息{com.android.sympla/com.android.sympla.LoginActivity}:android.view.InflateException:二进制XML文件行#28:二进制XML文件行#28:膨胀类EditText时出错
然而,当我注释掉两个EditText时,一切都正常。你知道我为什么有这样奇怪的行为吗?确保你的gradle文件中有以下依赖项:
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:design:22.2.0'
试试这个
<android.support.design.widget.TextInputLayout
android:id="@+id/testingInputLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/Theme.AppCompat">
<EditText
android:id="@+id/testingEditText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/testText"
android:inputType="textEmailAddress" />
</android.support.design.widget.TextInputLayout>
尝试使用
文本输入文本

android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TextInputEditText
android:layout_width="match_parent"
