小编use*_*378的帖子

我有一个带浮动提示的EditText,但我想知道如何减少浮动提示和EditText框之间的空间.

现在我的UI看起来像http://imgur.com/9hQzzx4,我想减少"标题"浮动提示和EditText框之间的空间.

这是我的xml文件的代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical">

    <android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" >

    </android.support.v7.widget.Toolbar>

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="16dp"
        android:layout_marginLeft="16dp"
        android:layout_marginRight="16dp">

        <EditText
            style="@style/Widget.AppCompat.EditText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textSize="40dp"
            android:hint="Title"/>

    </android.support.design.widget.TextInputLayout>

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="16dp"
        android:layout_marginRight="16dp">

        <EditText
            style="@style/Widget.AppCompat.EditText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textSize="32dp"
            android:hint="Details"/>

    </android.support.design.widget.TextInputLayout>

</LinearLayout>

所以我一直得到一个"java.lang.RuntimeException:这个图包含循环依赖"错误,我很确定是由我从AppBarLayout.ScrollingViewBehavior扩展的行为引起的.我有一个使用此行为的AppBarLayout布局,如果我删除行为,错误消失.这是行为的错误和代码
