1.控件点击加水波纹效果
android:background="?android:attr/selectableItemBackground"//有边界
android:background="?android:attr/selectableItemBackgroundBorderless"//无边界
2.Guideline的使用
<androidx.constraintlayout.widget.Guideline
android:id="@+id/gl"
android:layout_width="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5"
android:layout_height="wrap_content"/>
3.Spannable富文本
private fun setDescText() {
val str =
"By creating your account you agree to your personal data being stored and processed according to our Service-Agreement and Privacy-Policy."
val start1 = str.indexOf("Service-Agreement")
val end1 = start1 + "Service-Agreement".length
val spannable = SpannableStringBuilder(str)
spannable.setSpan(
ForegroundColorSpan(ContextCompat.getColor(requireContext(), R.color.btn_blue)),
start1,
end1,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
)
val start2 = str.indexOf("Privacy-Policy.")
val end2 = start2 + "Privacy-Policy.".length
spannable.setSpan(
ForegroundColorSpan(ContextCompat.getColor(requireContext(), R.color.btn_blue)),
start2,
end2,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
)
mBinding.tvDescroption.movementMethod = LinkMovementMethod.getInstance()
//设置点击事件1
spannable.setSpan(object : ClickableSpan() {
override fun onClick(widget: View) {
LogUtils.d("click1")
openWebPage(1)
}
}, start1, end1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
//设置点击事件2
spannable.setSpan(object : ClickableSpan() {
override fun onClick(widget: View) {
LogUtils.d("click2")
openWebPage(2)
}
}, start2, end2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
