Cardview中的ConstraintLayout添加了空白区域

Question

我想创建一个CardView具有ConstraintLayout组织一些TextView.

有时它会按预期显示,但有时会增加额外的空白区域,例如键盘关闭时会破坏布局.我有一个GIF下面显示CardView工作,而不是在相同的时间段内工作.

相关的代码段CardView如下.我wrap_content试图保持CardView我想要的大小,但它仍然扩大.

    <android.support.v7.widget.CardView
    android:id="@+id/cardView_game_cash"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_margin="6dp"
    app:cardCornerRadius="4dp"
    app:contentPadding="6dp"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <TextView
            android:id="@+id/textView_game_cashLabel"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="Total Cash"
            app:layout_constraintLeft_toLeftOf="@+id/textView_game_cash"
            app:layout_constraintRight_toRightOf="@+id/textView_game_cash"
            app:layout_constraintTop_toTopOf="parent" />

        <TextView
            android:id="@+id/textView_game_totalProfitLabel"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="Total Profit"
            app:layout_constraintLeft_toLeftOf="@+id/textView_game_totalProfit"
            app:layout_constraintRight_toRightOf="@+id/textView_game_totalProfit"
            app:layout_constraintTop_toTopOf="parent" />

        <TextView
            android:id="@+id/textView_game_profitLabel"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="Win Profit"
            app:layout_constraintLeft_toLeftOf="@+id/textView_game_profit"
            app:layout_constraintRight_toRightOf="@+id/textView_game_profit"
            app:layout_constraintTop_toTopOf="parent" />

        <TextView
            android:id="@+id/textView_game_cash"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:background="@color/colorAccent"
            android:gravity="center"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toLeftOf="@+id/textView_game_totalProfit"
            app:layout_constraintTop_toBottomOf="@+id/textView_game_cashLabel"
            tools:text="TextView" />

        <TextView
            android:id="@+id/textView_game_totalProfit"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:background="@color/colorPrimary"
            android:gravity="center"
            app:layout_constraintLeft_toRightOf="@+id/textView_game_cash"
            app:layout_constraintRight_toLeftOf="@+id/textView_game_profit"
            app:layout_constraintTop_toTopOf="@+id/textView_game_cash"
            tools:text="TextView" />

        <TextView
            android:id="@+id/textView_game_profit"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:background="@color/colorAccent"
            android:gravity="center"
            app:layout_constraintLeft_toRightOf="@+id/textView_game_totalProfit"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="@+id/textView_game_cash"
            tools:text="TextView" />
    </android.support.constraint.ConstraintLayout>

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

我找到了解决问题的方法.在TextView内部ConstraintLayout,我换成android:layout_height="wrap_content"

有:

android:layout_height="0dp" app:layout_constraintHeight_default="wrap"

布局按预期工作,并对所有TextView内部进行更改.
