我有两组代表所有数据和选定数据的数组

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".MyTaskActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">


        <android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/AppTheme.AppBarOverlay">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorPrimary"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

        </android.support.design.widget.AppBarLayout>

        <include layout="@layout/content_task" />
    </LinearLayout>

<ScrollView
    android:layout_width="match_parent"
    android:id="@+id/bottom_sheet"
    android:layout_height="wrap_content"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior">



        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <Button
                android:id="@+id/buildProjectButton"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="@string/buildProject" />

            <Button
                android:id="@+id/buildTaskButton"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="@string/buildTask" />

        </LinearLayout>

</ScrollView>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/floatingActionButtionTask"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@android:drawable/ic_input_add" />
</android.support.design.widget.CoordinatorLayout>

我想制作检查$ all_data value = $ selected value的所有数据列表什么是使它成为可能的最佳方法？

Answer 1

试试这段代码 -

<?php
$all_data = ["admin","member","editor"];
$selected = ["admin","member"];

foreach($all_data as $value) {
  $checked = in_array($value, $selected) ? 'checked="checked"' : '';
  echo '<input type="checkbox" name="chk[]" value="' . $value .'" ' . $checked . '>';
}
?>

从数组中设置选中复选框
