Question

我正在尝试将多个芯片动态添加到芯片组。第一个看起来不错，但其他的则不能正确显示。但是当我使用XML时，它工作正常。请帮助。

activity_main.xml

    <com.google.android.material.chip.ChipGroup
        android:id="@+id/chip_group_main"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginTop="2dp"
        app:chipSpacingHorizontal="4dp">

        <com.google.android.material.chip.Chip
            style="@style/ChipTextAppearance"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Hello"
            app:chipBackgroundColor="@color/colorAccent"
            app:closeIconEnabled="true" />

        <com.google.android.material.chip.Chip
            style="@style/ChipTextAppearance"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="World"
            app:chipBackgroundColor="@color/colorAccent"
            app:closeIconEnabled="true" />


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

@Override 受保护的无效onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; setContentView（R.layout.activity_main）;

Chip chip = new Chip(this);
chip.setText("ABC");
chip.setChipBackgroundColorResource(R.color.colorAccent);
chip.setCloseIconVisible(true);
chip.setTextColor(getResources().getColor(R.color.white));
chip.setTextAppearance(R.style.ChipTextAppearance);

Chip chip2 = new Chip(this);
chip.setText("XYZ");
chip.setChipBackgroundColorResource(R.color.colorAccent);
chip.setCloseIconVisible(true);
chip.setTextColor(getResources().getColor(R.color.white));
chip.setTextAppearance(R.style.ChipTextAppearance);


ChipGroup chipGroup = findViewById(R.id.chip_group_main);

chipGroup.addView(chip);
chipGroup.addView(chip2);

style.xml

<resources>
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="ChipTextAppearance" parent="TextAppearance.MaterialComponents.Chip">
    <item name="android:textColor">@android:color/white</item>
    <item name="android:textSize">12sp</item>
</style>
</resources>

standalone_chip.xml

<?xml version="1.0" encoding="utf-8"?>
<chip xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:chipBackgroundColor="@color/colorAccent"
app:closeIconEnabled="true"
style="@style/ChipTextAppearance"
app:closeIconTint="@android:color/white" />```

Answer 1

在主要活动中，您正在这样做。

test = 0
for i in range(5):
  if i == 0:
   test = i

请注意，您正在创建芯片的新实例，即chip2，但是在下一行中将更改芯片而不是chip2实例，因此您以前所做的任何更改都不会影响chip2。因此，为了解决此问题，请像这样更改您的代码

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        Chip chip = new Chip(this);
        chip.setText("ABC");
        chip.setChipBackgroundColorResource(R.color.colorAccent);
        chip.setCloseIconVisible(true);
        chip.setTextColor(getResources().getColor(R.color.white));
        chip.setTextAppearance(R.style.ChipTextAppearance);

        Chip chip2 = new Chip(this);
        chip.setText("XYZ");
        chip.setChipBackgroundColorResource(R.color.colorAccent);
        chip.setCloseIconVisible(true);
        chip.setTextColor(getResources().getColor(R.color.white));
        chip.setTextAppearance(R.style.ChipTextAppearance);


        ChipGroup chipGroup = findViewById(R.id.chip_group_main);

        chipGroup.addView(chip);
        chipGroup.addView(chip2);

Answer 2

是的，可以添加筹码与 chipGroup.addView(chip);分组请注意，您应该为每个芯片添加ID，以使组的某些功能正常运行（例如singleSelection="true"）

 chip.setId(ViewCompat.generateViewId());

动态向芯片组添加芯片
