Замените GridLayout на LinearLayout

У меня есть GridLayout, который отображает экран калькулятора. Он выглядит очень хорошо на многих устройствах, но совершенно не работает на маленьких дисплеях и даже на некоторых больших дисплеях. Есть ошибка в реализации GridLayout, но Google не работает над ней. Вы можете увидеть подробности в моем вопросе полугодовой давности и принятом ответе: GridLayout сворачивается на маленьком экране

Я попытался заново реализовать свой макет. Начал с нового ConstraintLayout без везения. LinearLayout довольно близко, но растянуть отдельные ячейки мне не удалось. Они не заполняют доступное пространство. Когда я меняю ширину с wrap_content на match_parent, макет полностью ломается.

Как добиться желаемого внешнего вида, который будет работать на всех устройствах?

как насчет использования вложенного линейного макета? родительский линейный макет с вертикальной ориентацией и вложенные макеты вкладышей с весом = 1 и высотой = 0. кнопки внутри внутреннего линейного макета должны иметь одинаковый вес с шириной = 0   -  person Swati    schedule 18.08.2017

Сделайте вашу кнопку width на 0dp, height на match_parent и layout_weight на 1, как в примере ниже для одной строки

    <!-- row with 7-9,+ -->
    <LinearLayout
        android:layout_height="0dp"
        android:layout_weight="1"
        android:weightSum ="4"
        android:orientation="horizontal"
        android:layout_width="match_parent">
    <Button
        android:id="@+id/digit7"
        android:text="7"
        style="@style/KeypadLeftButton"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        tools:ignore="HardcodedText"  />

    <Button
        android:id="@+id/digit8"
        android:text="8"
        style="@style/KeypadButton"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        tools:ignore="HardcodedText"  />

    <Button
        android:id="@+id/digit9"
        android:text="9"
        style="@style/KeypadButton"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        tools:ignore="HardcodedText" />

    <Button
        android:id="@+id/buttonPlus"
        android:text="+"
        style="@style/KeypadFunctionRightButton"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        tools:ignore="HardcodedText" />
    </LinearLayout>
</LinearLayout>

Используя ConstraintLayouts, вы можете добиться этого:
