再次检查单选组 android 中的单选按钮
check radio button again in radio group android
我正在使用包含两个单选按钮的单选组,如下所示:
<RadioGroup
android:layout_width="match_parent"
android:layout_marginStart="@dimen/dp_16"
android:layout_marginEnd="@dimen/dp_16"
android:layout_height="wrap_content"
app:layout_constraintTop_toTopOf="parent">
<RadioButton
android:id="@+id/rbDebitCard"
android:fontFamily="@font/sf_ui_regular"
android:textColor="@color/txt_color_heading"
android:layout_width="match_parent"
android:drawableEnd="@drawable/debit_card"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Pay with Card"/>
<View
android:layout_width="match_parent"
android:layout_height="@dimen/dp_1"
android:layout_marginTop="@dimen/dp_16"
android:background="@color/divider_line"/>
<RadioButton
android:id="@+id/rbCash"
android:fontFamily="@font/sf_ui_regular"
android:textColor="@color/txt_color_heading"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:checked="true"
android:drawableEnd="@drawable/cash"
android:layout_marginTop="@dimen/dp_16"
android:text="Cash"/>
</RadioGroup>
在我的 kotlin 代码中,我在单击 rbDebitCard 时显示底部 sheet,并在关闭底部 sheet 时通过 ischecked=false 更改支票。
完全取消选中单选按钮。
问题是,当我再次点击同一个单选按钮时,它没有被选中。不过底部sheet开盘
如果我点击另一个单选按钮(显然被选中)然后再次点击第一个按钮然后它被选中并打开底部 sheet。但是我再次关闭底部 sheet 并单击单选按钮,它没有被选中。
作为参考,下面是 kotlin 代码:
//pay with card
rbDebitCard.setOnClickListener {
rbDebitCard.isChecked = true
paymentMode = "Card"
onBraintreeSubmit(clContainer)
}
//Cash
rbCash.setOnClickListener {
paymentMode = "Cash"
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (requestCode == BundleConstants.REQ_CODE_PAYMENT) {
if (resultCode == Activity.RESULT_OK) {
// use the result to update your UI and send the payment method nonce to your server
val result: DropInResult = data!!.getParcelableExtra(DropInResult.EXTRA_DROP_IN_RESULT)
Log.e("payment result nonce", result.paymentMethodNonce?.nonce)
makePayment(result.paymentMethodNonce?.nonce)
} else if (resultCode == Activity.RESULT_CANCELED) {
// the user canceled
rbDebitCard.isChecked = false
} else {
// handle errors here, an exception may be available in
val error = data!!.getSerializableExtra(DropInActivity.EXTRA_ERROR) as Exception
rbDebitCard.isChecked = false
}
}
}
将检查更改侦听器添加到单选按钮如下所示:
rgPayment.setOnCheckedChangeListener { group, checkedId ->
when(checkedId){
R.id.rbDebitCard->{
rbDebitCard.isChecked = true
paymentMode = "Card"
onBraintreeSubmit(clContainer)
}
R.id.rbCash->{
paymentMode = "Cash"
}
}
}
您必须获取无线电组的 ID 并像这样使用无线电组 checkedchangedlistener -
val checkedRadioButton = group?.findViewById(group.checkedRadioButtonId) as? RadioButton
checkedRadioButton?.let {
if (checkedRadioButton.isChecked)
Toast.makeText(applicationContext, "RadioGroup: ${group?.contentDescription} RadioButton: ${checkedRadioButton?.text}", Toast.LENGTH_LONG).show()
}
问题出在 rbDebitCard.isChecked = false
我将其替换为 rgPayment.clearCheck()
.
有了这个,我认为在单选组中一些检查必须由单选组维护,这也独立于手动分配给单选按钮的检查。
然而,这个东西解决了问题:)
