是否可以在Android TextView周围绘制边框?


当前回答

我找到的最简单的解决方案(而且实际可行):

<TextView
    ...
    android:background="@android:drawable/editbox_background" />

您可以在代码中添加以下内容:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle" >
    <solid android:color="#ffffff" />
    <stroke android:width="1dip" android:color="#4fa5d5"/>
</shape>

更改康斯坦丁·布罗夫的答案,因为在我的情况下不起作用:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@android:color/white" />
            <stroke android:width="2dip" android:color="#4fa5d5"/>
            <corners android:radius="7dp"/>
        </shape>
    </item>
</selector>

compileSdkVersion 26(Android 8.0),minSdkVersion 21(Android 5.0),targetSdkV版本26,实现“com.android.support:appcompat-v7:26.1.0”,等级:4.1

可以将可绘制的形状(带角的矩形)设置为视图的背景。

<TextView android:background="@drawable/frame"/>

矩形可绘制框架.xml(放入res/drawable文件夹):

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <solid android:color="@android:color/white" />
    <stroke android:width="1dip"
     android:color="#3d4caf"/>
    <corners android:radius="50dp"/>
</shape>

我只是在寻找一个类似的答案——它可以通过Stroke和以下覆盖来完成:

@Override
public void draw(Canvas canvas, MapView mapView, boolean shadow) {

Paint strokePaint = new Paint();
strokePaint.setARGB(255, 0, 0, 0);
strokePaint.setTextAlign(Paint.Align.CENTER);
strokePaint.setTextSize(16);
strokePaint.setTypeface(Typeface.DEFAULT_BOLD);
strokePaint.setStyle(Paint.Style.STROKE);
strokePaint.setStrokeWidth(2);

Paint textPaint = new Paint();
textPaint.setARGB(255, 255, 255, 255);
textPaint.setTextAlign(Paint.Align.CENTER);
textPaint.setTextSize(16);
textPaint.setTypeface(Typeface.DEFAULT_BOLD);

canvas.drawText("Some Text", 100, 100, strokePaint);
canvas.drawText("Some Text", 100, 100, textPaint);

super.draw(canvas, mapView, shadow); 
}

创建一个边框视图,背景颜色作为边框的颜色和文本视图的大小。将边框视图填充设置为边框的宽度。将文本视图背景色设置为文本视图所需的颜色。现在在边框视图中添加文本视图。
