如何为每个路径元素单独定义单击事件
我正在使用Android上的SVG文件。 Android Studio将SVG文件转换为包含矢量和路径元素的XML文件。 XML文件可以有多个＆＃34; path＆＃34;元素。问题从这里开始。我想为每个路径元素提供单独点击的功能，而无需使用webview。 （javascript的原因是冒险！）有没有办法做到这一点？
我无法使用点击的像素颜色。因为它们变化很大。 我可以将每个路径元素分成不同的XML文件。但是这条路也记住了它们的位置。当我想将每个XML文件添加到FrameLayout时，他们将矩形边缘扩展到手机边缘。即使他们在width和height属性中有wrap_content ..所以onClick事件被阻止了。 onClick事件只有一个。您可以检查照片中的蓝色边缘。每个图像视图的蓝色边缘相同：
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent">
<ImageView

android:layout_height="wrap_content"
app:srcCompat="@drawable/path_one" />
<ImageView

您可以使用RichPath库，它具有集成的OnClickListener，该库传递被单击的路径元素。 GitHub链接：https://github.com/tarek360/RichPath
将SVG定义为VectorDrawable并将其添加到XML
<com.richpath.RichPathView
android:id="@+id/ic_notifications"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:vector="@drawable/ic_notifications" />
并在代码中设置setOnPathClickListener：
richPathView.setOnPathClickListener(new RichPath.OnPathClickListener() {
@Override
public void onClick(RichPath richPath) {
if (richPath.getName().equals("path_name")) {
//TODO do an action when a specific path is clicked.
}
}
});

据我所知，使用VectorDrawables无法达到你想要的效果。我想你可能不得不将SVG加载到WebView中。
但是，您不必使用任何JavaScript。 WebView小部件有一种拦截链接请求的方法。请参阅WebView文档中的Handling Page Navigation。
您只需要使用<path>链接元素包围<a>个元素。
<svg ...etc...>
<a xlink:href="SOME_URL">
<path d="..."/>
</a>
....
</svg>
然后在shouldOverrideUrlLoading()方法中拦截＆＃34; SOME_URL＆＃34;，无论它是什么。
答案 2 :(得分：0)
如果将所有路径分成不同的ImageView-s，则可以像这样覆盖IV的所有onTouchListener：
firstImg.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
Bitmap bmp = Bitmap.createBitmap(v.getDrawingCache());
int color = bmp.getPixel((int) event.getX(), (int) event.getY());
if (color == Color.TRANSPARENT)
return false;
else {
// here you can handle your click event
return true;
}
}
});
但是要小心，这种方法会占用大量资源，因为每个触摸事件都会经过多个onTouch侦听器。
