AlertDialog自定义单选功能

先来看一下效果图：



说一下主要功能：点击充值方式弹出AlertDialog进行选择，说明一下item后面的那个checkbox是用来显示的，当然也可以设置点击。   没错就是这么简单

自定义AlertDialog的布局：写的比较low，请见谅

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="190dp"
android:background="@color/white"

</android.support.v7.widget.LinearLayoutCompat>

android:layout_width="match_parent"
android:layout_height="59dp"
android:layout_marginTop="10dp"
android:orientation="horizontal">

android:layout_width="25dp"
android:layout_height="25dp"
android:layout_gravity="center"
android:src="@mipmap/icon_pay_alipay" />

<android.support.v7.widget.AppCompatTextView
android:layout_width="0dp"

<android.support.v7.widget.AppCompatCheckBox

android:layout_centerVertical="true"
android:layout_marginStart="10dp"
android:background="@null"
android:button="@drawable/select_bg" />

</android.support.v7.widget.LinearLayoutCompat>

</LinearLayout>

主要代码，很简单

private void choosePayWay() {
dialog = new AlertDialog.Builder(getContext()).create();
dialog.show();
final Window window = dialog.getWindow();
if (window != null) {
window.setContentView(R.layout.dialog_select_pay_way);  // 设置布局
window.setGravity(Gravity.BOTTOM);  // 显示位置
window.setWindowAnimations(R.style.anim_panel_up_from_bottom);  // 设置dialog进入效果
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));  // 设置背景色为半透明
//设置属性
final WindowManager.LayoutParams params = window.getAttributes();
params.width = WindowManager.LayoutParams.MATCH_PARENT;
params.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND;
params.dimAmount = 0.5f;
window.setAttributes(params);
window.findViewById(R.id.dialog_select_pay_way_wechat).setOnClickListener(this);
window.findViewById(R.id.dialog_select_pay_way_alipay).setOnClickListener(this);
final String t = mWay.getText().toString().trim();
if (t.equals("微信充值")) {
window.findViewById(R.id.dialog_select_pay_way_wechat_selected).setSelected(true);
} else if (t.equals("支付宝充值")) {
window.findViewById(R.id.dialog_select_pay_way_alipay_selected).setSelected(true);
} else {
window.findViewById(R.id.dialog_select_pay_way_wechat_selected).setSelected(false);
window.findViewById(R.id.dialog_select_pay_way_alipay_selected).setSelected(false);
}
}
}

补充一下那个进入效果...

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="anim_panel_up_from_bottom" parent="@android:style/Animation">
<item name="android:windowEnterAnimation">@anim/push_bottom_in</item>
<item name="android:windowExitAnimation">@anim/push_bottom_out</item>
</style>
</resources>

<?xml version="1.0" encoding="utf-8"?><!-- 上下滑入式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate
android:duration="200"
android:fromYDelta="100%p"
android:toYDelta="0" />
</set>

<?xml version="1.0" encoding="utf-8"?><!-- 上下滑出式 -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="200"
android:fromYDelta="0"
android:toYDelta="50%p" />
</set>

基本就是这样，很简单。此篇文章仅作为防止自己以后脑子短路，不喜勿喷，谢谢。（本人小白）
