Just put the intent to your new activity in
只需将意图放在您的新活动中
fabImageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//here
startActivity(new Intent(YourCurrentActivity.this,NewActivity.class));
}
});

Your answer didn't work entirely for me.
If I pass thisin Intent I get an error in Studio that it can't resolve the constructor: Intent(View.OnClickListener, Class<NewActivity>).
I had to pass the upper Activity class into Intent or fab's View, like this:
@warlock 你的回答并不完全适合我。
如果我传入thisIntent，我会在 Studio 中收到一个错误，提示它无法解析构造函数：Intent(View.OnClickListener, Class<NewActivity>)。
我必须将上层 Activity 类传递到 Intent 或 fab 的视图中，如下所示：
fabImageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//here
startActivity(new Intent(MainActivity.this, NewActivity.class));
// or:
startActivity(new Intent(v.getContext(), NewActivity.class));
}
});

FloatingActionButton floatingActionButton=(FloatingActionButton)rootView.findViewById(R.id.fab);
floatingActionButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View view){
startActivity(new Intent(view.getContext(), NextActivity.class));
}
});
This works absolutely fine.
这工作得很好。

you should define your activity in androidmainfest.xml as
您应该在 androidmainfest.xml 中将您的活动定义为
<activity android:name=".MainActivity">
</activity>
