問題描述

下面是我當(dāng)前的簡(jiǎn)單 XML，但是我希望其中的 3 個(gè) TextView 是圓形的，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.

如何更改我的代碼?

<?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:我想要一個(gè)實(shí)際的圓形，而不是如下所示的彎曲邊緣矩形:

Note: I want an actual circle not the curved edge rectangle shown below:

推薦答案

我也在尋找解決這個(gè)問題的方法，我發(fā)現(xiàn)簡(jiǎn)單舒適的方法是將矩形 TextView 的形狀轉(zhuǎn)換為圓形.有了這個(gè)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:

1. 在名為circle.xml"的drawable文件夾中創(chuàng)建一個(gè)新的XML文件(例如)并用以下代碼填充它:

1. 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，您將創(chuàng)建 TextView 的新形式.在這種情況下，我創(chuàng)建了一個(gè)綠色圓圈.如果要添加邊框，則必須將以下代碼添加到上一個(gè)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" />

1. 使用以下代碼在可繪制文件夾中創(chuàng)建另一個(gè) XML 文件(rounded_textview.xml"):

1. 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>

這個(gè)文件將改變我們eligamos的TextView的方式.

This file will serve to change the way the TextView we eligamos.

1. 最后，在我們想要更改方式的 TextView 屬性部分，我們前往背景"并選擇創(chuàng)建的第二個(gè) XML 文件(rounded_textview.xml").

1. 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" />

通過這些步驟，TextView 不再是 TextView，而是矩形有一個(gè)圓形.只需更改形狀，而不是 TextView 的功能.結(jié)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:

另外我不得不說，這些步驟可以應(yīng)用于在屬性中具有背景"選項(xiàng)的任何其他組件.

Also I have to say that these steps can be applied to any other component having the option to "background" in the properties.

好運(yùn)！！
