如何使用 xml 在 android 中绘制来创建半圆填充形状？

Question

我想使用 xml drawble 创建一个半填充的圆形？

像这样

这是我到目前为止所做的努力

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#FCD83500"/>
    <size
        android:width="10dp"
        android:height="5dp"/>
    <corners
        android:bottomLeftRadius="50dp"
        android:bottomRightRadius="50dp"/>
</shape>

使用上面的代码我可以创建半圆但我不知道如何使半圆透明

我也访问过一些 SO post 但无法找到任何解决方案

How to define a circle shape in an Android xml drawable file?

如果需要更多信息，请告诉我。提前致谢。您的努力将不胜感激。

使用这个

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="90"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="90">
    <vector xmlns:android="http://schemas.android.com/apk/res/android"
        android:width="24dp"
        android:height="24dp"
        android:viewportWidth="314.015"
        android:viewportHeight="314.015">
        <path
            android:fillColor="#FCD83500"
            android:pathData="M157.007,0C70.291,0 0,70.289 0,157.007c0,86.712 70.29,157.007 157.007,157.007c86.709,0 157.007,-70.295 157.007,-157.007C314.014,70.289 243.716,0 157.007,0zM31.403,157.015c0,-69.373 56.228,-125.613 125.604,-125.613V282.62C87.631,282.62 31.403,226.38 31.403,157.015z" />
    </vector>
</rotate>

输出

最后我得到了使用 layer-list 实现此目的的解决方案

A LayerDrawable 是一个 drawable 对象，它管理其他 drawables 的数组。列表中的每个 drawable 都按列表的顺序绘制 - 列表中的最后一个 drawable 绘制在顶部。

我的代码

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:left="26px"
        android:right="26px">

        <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="oval"
            android:useLevel="false">
            <solid android:color="#00006AC5" />
            <size
                android:width="50dp"
                android:height="50dp" />
            <stroke
                android:width="2dp"
                android:color="#00BCD4" />
        </shape>

    </item>

    <item
        android:width="50dp"
        android:height="25dp"
        android:end="2dp"
        android:gravity="center"
        android:start="2dp"
        android:top="22dp">

        <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle">
            <solid android:color="#00BCD4" />
            <size
                android:width="10dp"
                android:height="5dp" />
            <corners
                android:bottomLeftRadius="50dp"
                android:bottomRightRadius="50dp" />
        </shape>

    </item>

</layer-list>

输出

我已经从 Vector Graphics 创建了代码：

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="314.015"
    android:viewportHeight="314.015">
    <path
        android:fillColor="#FCD83500"
        android:pathData="M157.007,0C70.291,0 0,70.289 0,157.007c0,86.712 70.29,157.007 157.007,157.007c86.709,0 157.007,-70.295 157.007,-157.007C314.014,70.289 243.716,0 157.007,0zM31.403,157.015c0,-69.373 56.228,-125.613 125.604,-125.613V282.62C87.631,282.62 31.403,226.38 31.403,157.015z" />
</vector>

输出将是：

现在如果你想按照你的角度显示：

您可以如下使用：

android:rotation="90"

在你的 ImageView

`TextView` 可绘制对象的更新：

为旋转可绘制对象创建自定义方法。

private Drawable rotate(Drawable drawable, int degree) {
    Bitmap iconBitmap = ((BitmapDrawable) drawable).getBitmap();

    Matrix matrix = new Matrix();
    matrix.postRotate(degree);
    Bitmap targetBitmap = Bitmap.createBitmap(iconBitmap, 0, 0, iconBitmap.getWidth(), iconBitmap.getHeight(), matrix, true);

    return new BitmapDrawable(getResources(), targetBitmap);
}

使用如下：

Drawable result = rotate(ContextCompat.getDrawable(mContext, R.drawable.ic_round), 90);
yourTextView.setCompoundDrawablesWithIntrinsicBounds(result, null, null, null);

Note: If you will find SVG image as you want then you do now have to do above code. I have tried to find image but didn't found so Rotation code is necessary here.

希望对您有所帮助。

谢谢。

试试这个：

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <stroke
                android:color="#FCD83500"
                android:width="1dp"/>
            <size
                android:width="20dp"
                android:height="20dp"/>
            <corners
                android:radius="50dp"/>
        </shape>
    </item>
    <item android:top="10dp">
        <shape android:shape="rectangle">
            <solid android:color="#FCD83500"/>
            <size
                android:width="20dp"
                android:height="10dp"/>
            <corners
                android:bottomLeftRadius="50dp"
                android:bottomRightRadius="50dp"/>
        </shape>
    </item>
</layer-list>

使用此代码制作半圆矢量图像。如果你想旋转矢量图像意味着使用带有旋转元素的组标签。参考这个

<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"

android:viewportWidth="314.015"
android:viewportHeight="314.015">
<group
    android:translateX="314.015"
    android:rotation="90">
<path
    android:fillColor="#FCD83500"
    android:pathData="M157.007,0C70.291,0 0,70.289 0,157.007c0,86.712 70.29,157.007 157.007,157.007c86.709,0 157.007,-70.295 157.007,-157.007C314.014,70.289 243.716,0 157.007,0zM31.403,157.015c0,-69.373 56.228,-125.613 125.604,-125.613V282.62C87.631,282.62 31.403,226.38 31.403,157.015z" />

</group>
</vector>
