Android:创建一个圆形 TextView?
下面是我当前的简单 XML，但是我希望其中的 3 个 TextView 是圆形的，而不是矩形的.
My current simple XML is below, however i would like the 3 TextViews within it to be circular, rather than rectangular.
如何更改我的代码?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/tvSummary1"
android:layout_width="270dp"
android:layout_height="60dp" >
</TextView>
<TextView
android:id="@+id/tvSummary2"
android:layout_width="270dp"
android:layout_height="60dp" >
</TextView>
<TextView
android:id="@+id/tvSummary3"
android:layout_width="270dp"
android:layout_height="60dp" >
</TextView>
</LinearLayout>
注意:我想要一个实际的圆形，而不是如下所示的弯曲边缘矩形:
Note: I want an actual circle not the curved edge rectangle shown below:
当前代码:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/tvSummary1"
android:layout_width="270dp"
android:layout_height="60dp"
android:text=" "
android:gravity="left|center_vertical"
android:background="@drawable/circle"/>
<TextView
android:id="@+id/tvSummary2"
android:layout_width="270dp"
android:layout_height="60dp"
android:background="@drawable/circle" >
</TextView>
<TextView
android:id="@+id/tvSummary3"
android:layout_width="270dp"
android:layout_height="60dp"
android:background="@drawable/circle" >
</TextView>
</LinearLayout>
当前输出:
推荐答案
我也在寻找解决这个问题的方法，我发现简单舒适的方法是将矩形 TextView 的形状转换为圆形.有了这个方法就完美了:
I was also looking for a solution to this problem and as easy and comfortable I found, was to convert the shape of a rectangular TextView to cirular. With this method will be perfect:
在名为circle.xml"的drawable文件夹中创建一个新的XML文件(例如)并用以下代码填充它:
Create a new XML file in the drawable folder called "circle.xml" (for example) and fill it with the following code:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#9FE554" />
<size
android:height="60dp"
android:width="60dp" />
</shape>
使用此文件，您将创建 TextView 的新形式.在这种情况下，我创建了一个绿色圆圈.如果要添加边框，则必须将以下代码添加到上一个文件中:
With this file you will create the new form of TextView. In this case, I created a circle of green. If you want to add a border, you would have to add the following code to the previous file:
<stroke
android:width="2dp"
android:color="#FFFFFF" />
使用以下代码在可绘制文件夹中创建另一个 XML 文件(rounded_textview.xml"):
Create another XML file ( "rounded_textview.xml") in the drawable folder with the following code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/circle" />
</selector>
这个文件将改变我们eligamos的TextView的方式.
This file will serve to change the way the TextView we eligamos.
最后，在我们想要更改方式的 TextView 属性部分，我们前往背景"并选择创建的第二个 XML 文件(rounded_textview.xml").
Finally, in the TextView properties we want to change the way section, we headed to the "background" and select the second XML file created ( "rounded_textview.xml").
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="H"
android:textSize="30sp"
android:background="@drawable/rounded_textview"
android:textColor="@android:color/white"
android:gravity="center"
android:id="@+id/mark" />
通过这些步骤，TextView 不再是 TextView，而是矩形有一个圆形.只需更改形状，而不是 TextView 的功能.结果如下:
With these steps, instead of having a TextView TextView rectagular have a circular. Just change the shape, not the functionality of the TextView. The result would be the following:
另外我不得不说，这些步骤可以应用于在属性中具有背景"选项的任何其他组件.
Also I have to say that these steps can be applied to any other component having the option to "background" in the properties.
好运！！
