Question

我们将从图片开始：

我希望电子邮件地址的TextView和EditText位于徽标下方，但不知何故它位于徽标之上。

我的布局：

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<RelativeLayout

          android:textSize="20sp"
          android:textColor="#0b84aa"
          />

    </LinearLayout>
    <!-- Login Form Ends -->

   </RelativeLayout>

</ScrollView>

我做错了什么？因为所有LinearLayout方向都设置为垂直，所以为什么某些视图会在其他视图上对齐？

Answer 1

你父亲的容器是一个RelativeLayout，所以孩子们必须以相对的方式定位＆＃34;＆＃34;彼此之间。例如：linear_layout_footer_id应使用

置于linear_layout_header_id下

android:layout_below="@id/linear_layout_header_id"

其他解决方案：将RelativeLayout替换为另一个具有垂直方向的LinearLayout

Answer 2

由于您的父布局是相对的，因此您需要提供以下视图条件。这是使用xml的固定xml。

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

    android:layout_height="wrap_content" 
    android:background="@color/white_1" >

        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/header_gradient"

                android:contentDescription="@string/imgae_view_logo_content_description"
                />

    </LinearLayout>

      <!--  Email Label -->
      <TextView 
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:textColor="@color/black_1"
          android:text="@string/login_page_email_text_view_text"
          />

      <EditText
          android:id="@+id/login_page_email_edit_text_id"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_marginTop="5dip"
          android:layout_marginBottom="20dip"

          android:hint="@string/login_page_email_edit_text_hint"
          android:inputType="textEmailAddress"
          />

      <!--  Password Label -->
      <TextView 
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:textColor="#372c24"
          android:text="@string/login_page_password_text_vuew_text"
          />

      <EditText
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_marginTop="5dip"
          android:singleLine="true"
          android:inputType="textPassword"
          android:hint="@string/login_page_password_edit_text_hint"

      <!-- Login button -->
      <Button

          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_marginTop="10dip"

      <!-- Link to Registration Screen -->

          android:textSize="20sp"
          android:textColor="#0b84aa"
          />

    </LinearLayout>
    <!-- Login Form Ends -->

   </RelativeLayout>

</ScrollView>

如您所见，现在您的登录表单已获得条件

机器人：layout_below = “@ + ID / linear_layout_header_id”

所以它会低于标题。

Answer 3

添加此代码

android:layout_below="@+id/linear_layout_header_id"

到LinearLayout应该低于Logo

Answer 4

将android:layout_below="@+id/linear_layout_header_id"添加为

    <!-- Login Form -->
    <LinearLayout
        android:layout_below="@+id/linear_layout_header_id"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="10dip" >

        </LinearLayout>

    </RelativeLayout>

</ScrollView>

相对布局相对布置其所有布局。如果您没有指定任何相对属性，那么它的所有子项都将重叠。

希望它会有所帮助。!!

Answer 6

您正在LinerLayouts中安排RelativeLayouts，因此您需要确保LinearLayouts相对于彼此。尝试添加属性android:layout_below。

LinearLayout没有按照我的意愿对齐
