我正在尝试使动态数字键盘视图具有圆形形状,但是问题是,当我分配背景时,它不能正确显示我正在使用权重,因此它可以在所有屏幕尺寸和方向上工作,如何才能实现这是我的布局< / p>

如何在不使用静态间距和权重的情况下进行此布局,请帮助我做错了什么?

使用ConstraintLayout如下:

可绘制形状: your_drawable.xml
<?xml version="1.0" encoding="utf-8"?>

android:shape="oval">
<solid android:color="#4588C0" />
<stroke

android:color="#ffffff" />
</shape>
如果要以白色显示按下/选中的按钮,则必须创建可绘制的选择器并将其提供给按钮背景。

以此更改背景可绘制背景
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<!-- fill color -->
<solid android:color="@color/colorAccent"/>
<!-- radius -->
<stroke
android:width="1dp"
android:color="@color/colorAccent"/>
<size
android:width="50dp"
android:height="50dp"/>
<!-- corners -->
<corners
android:radius="2dp"/>
根据需要更改尺寸, 您可以使用约束布局或其他方法来实现这种设计

答案 2 :(得分:2)
首先,我会告诉您使用最新的约束布局,它在设计中效率更高。 @Viraj Patel回答他使用约束布局。
但是您想要在相对布局中实现相同的设计。这很容易。看看这个
第1步
首先创建中心按钮,使其垂直和水平居中。您只需要将此行添加到中心按钮即可。
android:layout_centerInParent =“ true”
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/parent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorPrimaryDark">
<Button
android:id="@+id/btn_digit5"
android:layout_width="70dp"
android:layout_height="70dp"
android:text="5"
android:textColor="@android:color/white"
android:background="@drawable/circle"
android:layout_centerInParent="true"/>
</RelativeLayout>
Am添加了静态宽度和高度以使其成为背景圆。如果要使用WRAP_CONTENT
或MATCH_PARENT
来制作按钮圈,请在运行时用Java代码完成。这里正在使用静态值。
第2步
然后,您可以根据中心按钮和另外两个属性值添加更多按钮。
android:layout_centerHorizontal =“ true”
android:layout_centerVertical =“ true”
现在,我添加Digit4
和Digit6
,它们与Digit5
垂直对齐。下面的代码将为您提供结果
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/parent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorPrimaryDark">
<Button
android:id="@+id/btn_digit5"
android:layout_width="70dp"
android:layout_height="70dp"
android:text="5"
android:textColor="@android:color/white"
android:background="@drawable/circle"
android:layout_centerInParent="true"/>
<Button
android:id="@+id/btn_digit4"
android:layout_width="70dp"
android:layout_height="70dp"
android:background="@drawable/circle"
android:layout_toLeftOf="@+id/btn_digit5"
android:layout_marginRight="20dp"
android:text="4"
android:layout_centerVertical="true"
android:textColor="@android:color/white" />
<Button
android:id="@+id/btn_digit6"
android:layout_width="70dp"
android:layout_height="70dp"
android:background="@drawable/circle"
android:layout_toRightOf="@+id/btn_digit5"
android:layout_marginLeft="20dp"
android:text="6"
android:layout_centerVertical="true"
android:textColor="@android:color/white" />
</RelativeLayout>
向此按钮添加to_leftof
和to_rightof
属性并垂直对齐该属性,并同时添加边距值。
第3步
现在,我添加了Digit2
和Digit8
,它们与Digit5
水平对齐。下面的代码将为您提供结果
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/parent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorPrimaryDark">
<Button
android:id="@+id/btn_digit5"
android:layout_width="70dp"
android:layout_height="70dp"
android:text="5"
android:textColor="@android:color/white"
android:background="@drawable/circle"
android:layout_centerInParent="true"/>
<Button
android:id="@+id/btn_digit2"
android:layout_width="70dp"
android:layout_height="70dp"
android:background="@drawable/circle"
android:layout_above="@+id/btn_digit5"
android:layout_marginBottom="20dp"
android:text="2"
android:layout_centerHorizontal="true"
android:textColor="@android:color/white" />
<Button
android:id="@+id/btn_digit4"
android:layout_width="70dp"
android:layout_height="70dp"
android:background="@drawable/circle"
android:layout_toLeftOf="@+id/btn_digit5"
android:layout_marginRight="20dp"
android:text="4"
android:layout_centerVertical="true"
android:textColor="@android:color/white" />
<Button
android:id="@+id/btn_digit6"
android:layout_width="70dp"
android:layout_height="70dp"
android:background="@drawable/circle"
android:layout_toRightOf="@+id/btn_digit5"
android:layout_marginLeft="20dp"
android:text="6"
android:layout_centerVertical="true"
android:textColor="@android:color/white" />
<Button
android:id="@+id/btn_digit8"
android:layout_width="70dp"
android:layout_height="70dp"
android:background="@drawable/circle"
android:text="8"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:layout_below="@+id/btn_digit5"
android:textColor="@android:color/white" />
</RelativeLayout>
在此按钮上添加layout_below
和layout_above
属性和水平对齐属性,并同时添加边距值。
第4步
借助相对布局属性to_leftof
to_right_of
layout_above
layout_below
添加边角数字。看看这个
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
