使用Android Material Chip
使用Android Material Chip
提问于 2018-09-27 06:08:46
大家好，我是android新手，正在学习如何使用材料芯片。我已经创建了一个测试项目并添加了以下内容
在我的gradle文件中我添加了
implementation 'com.android.support:design:28.0.0'在我的xml片段中，我添加了
<android.support.design.chip.Chip
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="test chip"/>但是我一直收到这个错误

... 31 more看起来android.support.design.chip.Chip有一个问题，我试过使用com.google.android.material.chip.Chip，但也不起作用，任何帮助都将不胜感激！谢谢!

我们可以通过MaterialComponent主题为芯片使用support.design。
在您的活动中使用此样式
<style name="ChipStyle" parent="Theme.MaterialComponents.Light.NoActionBar">
<!-- Your style -->
</style>并在您的活动中创建ChipGroup组件
<android.support.design.chip.ChipGroup
android:id="@+id/cg_filter_items"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_margin="16dp"
android:padding="16dp"
app:chipSpacing="8dp"
app:layout_constraintBottom_toTopOf="@id/btn_apply_filter"
app:layout_constraintTop_toBottomOf="@id/tv_filter_heading" />创建新的xml文件item_filter_chip.xml，即ChipGroup style="@style/TextAppearance.MaterialComponents.Chip"的项目。此行对于膨胀项目非常重要。
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.chip.Chip
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/chips_item_filter"
style="@style/TextAppearance.MaterialComponents.Chip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="4dp" />使用此代码动态生成芯片
ChipGroup chipGroup = findViewById(R.id.cg_filter_items);
for (int i = 0; i < 10; i++) {
View view = LayoutInflater.from(this).inflate(R.layout.item_filter_chips, chipGroup, false);
Chip chip = view.findViewById(R.id.chips_item_filter);
chip.setText("chip Text " + i);
chip.setClickable(true);
chip.setCheckable(true);
chipGroup.addView(chip);
chip.setOnClickListener(<Your Listener>);

您必须设置您的AppTheme，使其继承其中一个MaterialComponent主题才能使用芯片。如果您仍想使用AppCompat，请尝试使用桥主题。
在Getting Started with Material Components上按照本指南中的步骤操作。
