我希望在约束布局中有2列网格和方形按钮这是我的xml
但是当我添加4按钮时它会显示一个大按钮:
当我删除2个按钮时,每件事情都很有效:
<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="wrap_content"
tools:context="com.example.poory.myapplication.MainActivity">
<Button
android:id="@+id/button"
app:layout_constraintTop_toBottomOf="@id/slider"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintDimensionRatio="H,1:1"
android:text="Button"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="@+id/button2"
android:layout_marginTop="0dp" />
<Button
android:id="@+id/button2"
app:layout_constraintTop_toBottomOf="@id/slider"
android:layout_width="0dp"
android:layout_height="0dp"
android:text="Button"
app:layout_constraintDimensionRatio="H,1:1"
tools:layout_editor_absoluteY="232dp"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintLeft_toRightOf="@+id/button" />
<Button
android:id="@+id/button3"
app:layout_constraintTop_toBottomOf="@id/button"
android:layout_width="0dp"
android:layout_height="0dp"
android:text="Button"
app:layout_constraintDimensionRatio="H,1:1"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="@+id/button2" />
<Button
android:id="@+id/button4"
app:layout_constraintTop_toBottomOf="@id/button2"
android:layout_width="0dp"
android:layout_height="0dp"
android:text="Button"
app:layout_constraintDimensionRatio="H,1:1"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintLeft_toRightOf="@+id/button" />
</android.support.constraint.ConstraintLayout>
这个网格应该在scrollview
,所以我不能使用父母的底部。
答案 0 :(得分:3)
我添加了一份适用于我的指南。
<Button
