增加TextView的触控目标

<TextView
    android:id="@+id/myTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:text="Hello World!" />

final View parentView = (View) textView.getParent();
parentView.post(new Runnable() {
    @Override
    public void run() {
        Rect bounds = new Rect();
        textView.getHitRect(bounds);
        bounds.top -= 10;
        bounds.bottom += 10;
        bounds.left -= 10;
        bounds.right += 10;
        TouchDelegate touchDelegate = new TouchDelegate(bounds, textView);
        parentView.setTouchDelegate(touchDelegate);
    }
});

SpannableString spannableString = new SpannableString("Click me");
ClickableSpan clickableSpan = new ClickableSpan() {
    @Override
    public void onClick(View widget) {
        // 处理点击事件
    }
};
spannableString.setSpan(clickableSpan, 0, spannableString.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(spannableString);
textView.setMovementMethod(LinkMovementMethod.getInstance());
