将GridLayout替换为LinearLayout
将GridLayout替换为LinearLayout
提问于 2017-08-18 18:27:47
我有一个显示计算器屏幕的GridLayout。它在许多设备上看起来很不错，但在小型显示器甚至一些大显示器上却完全失败。有一个GridLayout实现中的错误，但谷歌并没有在这方面工作。你可以在我半岁的问题和一个公认的答案中看到细节：GridLayout在小型显示器上崩溃
我试图重新实现我的布局。我从没有运气的新ConstraintLayout开始。LinearLayout非常接近，但我未能伸展单个细胞。它们无法填补可用的空间。当我将宽度从wrap_content更改为match_parent时，布局完全中断。
所有源代码和示例应用程序都可以在https://github.com/literakl/CalcTrouble上获得。

使按钮的width到0dp，height到match_parent，layout_weight到1，如下所示，单行示例如下所示
<!-- 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"

使用ConstraintLayouts，您可以实现以下目标：
