Question

我正在使用布局我的屏幕。除了我希望我的ImageView在其宽度和高度上“match_parent”而不占用整个屏幕之外，一切都设置得很完美。我的布局是这样的：

Label 1
ImageView
Label 2
Button

我希望我的标签占据一些空间，然后我的底部占据屏幕底部。然后，我希望ImageView占用剩余的可用空间。这可能不会杀死我所有的约束吗？现在，当ImageView设置为match_parent时，它会占用整个屏幕并隐藏标签和按钮。

由于

这是代码，请注意，还有TextViews放置在图像的顶部特定位置因此所有空间：

Answer 1

试试这个。

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent">

  <TextView
    android:id="@+id/label1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:textSize="24sp"
    tools:text="Label 1"/>

  <ImageView
    android:id="@+id/image_view"
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:layout_constraintTop_toBottomOf="@+id/label1"
    app:layout_constraintBottom_toTopOf="@+id/label2"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    android:src="#aaaaee"/>

  <TextView
    android:id="@+id/label2"
    android:layout_width="match_parent"
    android:layout_height="80dp"
    tools:text="Label 1"
    android:gravity="center_vertical"
    android:textSize="24sp"
    app:layout_constraintBottom_toTopOf="@+id/button"/>

  <Button
    android:id="@+id/button"
    android:layout_width="0dp"
    android:layout_height="64dp"
    android:background="#f7594d"
    android:textColor="@android:color/white"
    android:textSize="22sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    tools:text="BUTTON"/>

</android.support.constraint.ConstraintLayout>

它显示：

处理ConstraintLayout时，视图主要由约束定义。

例如，您可以像这样定义一个简单的TextView。

<TextView
  android:id="@+id/label1"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:gravity="center_vertical"
  android:textSize="24sp"
  tools:text="Label 1"/>

使用ConstraintLayout时：

<TextView
  android:id="@+id/label1"
  android:layout_width="0dp"
  android:layout_height="wrap_content"
  android:gravity="center_vertical"
  android:textSize="24sp"
  app:layout_constraintLeft_toLeftOf="parent"
  app:layout_constraintRight_toRightOf="parent"
  tools:text="Label 1"/>

两者都给你相同的结果。我更喜欢第二种方式，但我认为这取决于你。

- 修改

这是你的ImageView：

<ImageView
  android:id="@+id/wkm_cardiagram_img"
  android:layout_width="352dp"
  android:layout_height="416dp"
  android:layout_marginEnd="8dp"
  android:layout_marginStart="8dp"
  android:layout_marginTop="8dp"
  android:layout_weight="0"
  android:scaleType="fitXY"
  android:src="@drawable/vehicle_schematic_image"
  app:layout_constraintEnd_toEndOf="parent"
  app:layout_constraintStart_toStartOf="parent"
  app:layout_constraintTop_toBottomOf="@+id/wkm_cardiagram_orientation1" />

首先，如果要调整视图的大小，需要将宽度/高度设置为0.如果不是，请手动设置宽度/高度。

<ImageView
  android:id="@+id/wkm_cardiagram_img"
  android:layout_width="0dp"
  android:layout_height="0dp"
  android:layout_marginEnd="8dp"
  android:layout_marginStart="8dp"
  android:layout_marginTop="8dp"
  android:layout_weight="0"
  android:scaleType="fitXY"
  android:src="#fff999"
  app:layout_constraintEnd_toEndOf="parent"
  app:layout_constraintStart_toStartOf="parent"
  app:layout_constraintTop_toBottomOf="@+id/wkm_cardiagram_orientation1"
  app:layout_constraintBottom_toTopOf="@+id/wkm_cardiagram_orientation2"/>

其次，这是你的label2和按钮..看起来像底部没有约束。所以我放了一些代码。

<TextView
  android:id="@+id/wkm_cardiagram_orientation2"
  android:layout_width="match_parent"
  android:layout_height="15dp"
  android:layout_marginTop="8dp"
  android:gravity="center"
  android:text="OrientationLabel2"
  android:textColor="@android:color/black"
  android:textSize="12sp"
  app:layout_constraintEnd_toEndOf="parent"
  app:layout_constraintHorizontal_bias="0.0"
  app:layout_constraintStart_toStartOf="parent"
  app:layout_constraintTop_toBottomOf="@+id/wkm_cardiagram_img"
  >> app:layout_constraintBottom_toTopOf="@+id/wkm_cardiagram_submit"/>


<Button
  android:id="@+id/wkm_cardiagram_submit"
  android:layout_width="match_parent"
  android:layout_height="40dp"
  android:layout_gravity="center_horizontal|center"
  android:layout_marginTop="8dp"
  android:background="@color/btnBlueSelectedStart"
  android:gravity="center"
  android:text="Submit"
  android:paddingRight="5dp"
  android:paddingLeft="5dp"
  app:layout_constraintEnd_toEndOf="parent"
  app:layout_constraintEnd_toStartOf="parent"
  android:textColor="@color/white"
  app:layout_constraintTop_toBottomOf="@id/wkm_cardiagram_orientation2"
  tools:layout_editor_absoluteX="0dp"
  >> app:layout_constraintBottom_toBottomOf="parent"/>

确保你应用了所有必需的约束..！

Answer 2

非常简单@mint。最初不要使代码过于复杂。尝试建立我给你的简单结构。

为主体创建RelativeLayout。
在RelativeLayout中，创建您想占用空间的任何布局，并将其宽度和高度指定为“匹配父母”。
然后创建另一个布局（如果你想在屏幕底部有一个条形，最好是一个水平的LinearLayout - 你可以放置你想要的多个按钮）。
在属性
后分配此其他布局
机器人：layout_alignParentBottom =＆＃34;真＆＃34;

你完成了！使用以下代码作为示例（它是一个滚动视图，底部有一个固定条/按钮）：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </ScrollView>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimary"
        android:layout_alignParentBottom="true">

        <android.support.v7.widget.AppCompatTextView
            android:id="@+id/submitButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="SUBMIT"
            />
    </LinearLayout>

</RelativeLayout>

Android约束布局
