Android Material Chip - ChipGroup with singleSelection 无法动态添加筹码

Question

我是第一次使用 Material Chip。

问题： 我正在使用以下代码动态添加芯片。请检查我写的 app:singleSelection="true" 这对我来说很重要。 即使它一次select发送多个筹码。

我想select 一次只有一个带刻度的筹码。

XML代码：

<com.google.android.material.chip.ChipGroup
                android:id="@+id/categoryChipsView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center_vertical"
                android:orientation="horizontal"
                app:chipSpacing="10dp"
                app:singleSelection="true"
                app:itemSpacing="15dp"
                app:singleLine="true">
</com.google.android.material.chip.ChipGroup>

Java代码：

private void addChipView(String chipText) {
    View child = getLayoutInflater().inflate(R.layout.row_chip_view, null);
    Chip chip = child.findViewById(R.id.chip);
    chip.setText(chipText);
    chip.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(mContext, ((Chip) v).getText(), Toast.LENGTH_SHORT).show();
        }
    });
    // This is ChipGroup view
    binding.categoryChipsView.addView(child);
}

row_chip_view.xml

<com.google.android.material.chip.Chip xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/chip"
    style="@style/Widget.MaterialComponents.Chip.Filter"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:text="@string/app_name"
    android:textColor="@android:color/white"
    app:checkedIcon="@drawable/ic_check"
    app:chipBackgroundColor="@color/colorAccent"
    app:chipEndPadding="8dp"
    app:chipIconTint="@android:color/white"
    app:chipStartPadding="8dp"
    app:textEndPadding="5dp"
    app:textStartPadding="5dp" />

我已经静态地尝试过，我将 row_chip_view.xml 的视图作为 ChipGroup 的子项粘贴到主 xml 中，并且工作正常。我一次只能select一个筹码。

           <com.google.android.material.chip.ChipGroup
                android:id="@+id/categoryChipsView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center_vertical"
                android:orientation="horizontal"
                app:chipSpacing="10dp"
                app:singleSelection="true"
                app:itemSpacing="15dp"
                app:singleLine="true">

                <com.google.android.material.chip.Chip 
                    android:id="@+id/chip"
                    style="@style/Widget.MaterialComponents.Chip.Filter"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_margin="10dp"
                    android:text="@string/app_name"
                    android:textColor="@android:color/white"
                    app:checkedIcon="@drawable/ic_check"
                    app:chipBackgroundColor="@color/colorAccent"
                    app:chipEndPadding="8dp"
                    app:chipIconTint="@android:color/white"
                    app:chipStartPadding="8dp"
                    app:textEndPadding="5dp"
                    app:textStartPadding="5dp" />

                <com.google.android.material.chip.Chip 
                    android:id="@+id/chip2"
                    style="@style/Widget.MaterialComponents.Chip.Filter"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_margin="10dp"
                    android:text="@string/app_name"
                    android:textColor="@android:color/white"
                    app:checkedIcon="@drawable/ic_check"
                    app:chipBackgroundColor="@color/colorAccent"
                    app:chipEndPadding="8dp"
                    app:chipIconTint="@android:color/white"
                    app:chipStartPadding="8dp"
                    app:textEndPadding="5dp"
                    app:textStartPadding="5dp" />

                <com.google.android.material.chip.Chip 
                    android:id="@+id/chip3"
                    style="@style/Widget.MaterialComponents.Chip.Filter"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_margin="10dp"
                    android:text="@string/app_name"
                    android:textColor="@android:color/white"
                    app:checkedIcon="@drawable/ic_check"
                    app:chipBackgroundColor="@color/colorAccent"
                    app:chipEndPadding="8dp"
                    app:chipIconTint="@android:color/white"
                    app:chipStartPadding="8dp"
                    app:textEndPadding="5dp"
                    app:textStartPadding="5dp" />

            </com.google.android.material.chip.ChipGroup>

但我想要动态的。

Update: New Scenario

First of all I have added four chips in XML within ChipGroup and after that tried to add another three chips PROGRAMATICALLY in same ChipGroup. The first four chips is allow to select only one but last three chips allow me to select multiple. Very Weird.

如果我遗漏了什么，请告诉我。

我们将不胜感激。

Answer 1

而是 onClickListener 使用 setOnCheckedChangeListener 这对我来说与 singleSelection="true"

结合使用

Answer 2

删除在您的 row_chip_view.xml android:id 属性中。

<com.google.android.material.chip.Chip 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    style="@style/Widget.MaterialComponents.Chip.Filter"
    .../>

并在 addChipView 中使用：

private void addChipView(String chipText) {
    Chip chip = (Chip) getLayoutInflater().inflate(R.layout.row_chip_view, chipGroup, false);
    chip.setText(chipText);
    //...

    // This is ChipGroup view
    chipGroup.addView(chip);
}

Answer 3

在将 Chip 添加到 ChipGroup 之前添加整数 id

    Chip chip = (Chip) getLayoutInflater().inflate(R.layout.custom_chip, chipGroup,
  false);
            chip.setId(i);
            chip.setText("str");
            chipGroup.addView(chip);
