Invisible / transparent button that works like a regular in android?
提问by Xtreme
How do I get one area in the middle of a image clickable (not the whole image)? Tried with a button set to invisible and clickable but the button does not work. What are the alternatives to an invisible / transparent button that works like a regular?
如何使图像中间的一个区域可点击（不是整个图像）？尝试将按钮设置为不可见和可点击，但该按钮不起作用。像常规一样工作的隐形/透明按钮有哪些替代方案？
I've also thought of a completely transparent and clickable PNG that should work but maybe not the best way?
我还想到了一个完全透明且可点击的 PNG 应该可以工作，但可能不是最好的方法？

Here you go:
干得好：
Button theButton = (Button)findViewById(R.id.theButton);
theButton.setVisibility(View.VISIBLE);
theButton.setBackgroundColor(Color.TRANSPARENT);
phoneButton.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// DO STUFF
}
});

android:background="@android:color/transparent"

You can try set transparent background to the button. But do not change buttons visibility, cause that prevents view from getting click events.
您可以尝试为按钮设置透明背景。但是不要改变按钮的可见性，因为这会阻止视图获得点击事件。
