[英]How to set ViewPager with a ChipGroup android?
我有一个 ChipGroup,里面有 5 个芯片。 我有一个包含 5 页的视图寻呼机。 对于我选择的芯片,应该加载相应的页面(片段)。 如何在android中链接ViewPager和ChipGroup?
将app:singleSelection="true"
为您的芯片组 XML 参考此并像这样设置 ViewPager
private void setViewPager() {
mPagerAdapter = new PagerAdapter(getSupportFragmentManager());
if (mViewPagerGetStarted != null) {
mViewPagerGetStarted.setAdapter(mPagerAdapter);
mViewPagerGetStarted.addOnPageChangeListener(this);
mViewPagerGetStarted.setOffscreenPageLimit(4);
mTabLayoutGetStarted.setupWithViewPager(mViewPagerGetStarted);
}
ArrayList<String> categoryList = new ArrayList<>();
int numberOfFrag = mPagerAdapter.getCount();
for (int i = 0; i < numberOfFrag; i++) {
categoryList.add(mPagerAdapter.getPageTitle(i).toString());
}
addChipsToChipGroup(categoryList);
}
然后使用addChipsToChipGroup(categoryList);
将芯片动态添加到您的芯片组中addChipsToChipGroup(categoryList);
private void addChipsToChipGroup(List<String> items) {
if (items.size() >= 1) {
for (int i = 0; i < items.size(); i++) {
Chip chip = new Chip(mContext);
chip.setId(i);
ChipDrawable chipDrawable = ChipDrawable.createFromAttributes(this,
null,
0,
R.style.ChipTextStyle);
chip.setCloseIconTint(Utils.ColorStateListFromIntColor(mColorPrimary));
chip.setText(items.get(i));
chip.setTextColor(mColorPrimary);
chip.setChipDrawable(chipDrawable);
chip.setChipBackgroundColor(Utils.ColorStateListFromIntColor(mWhiteColor));
chip.setChipStrokeColor(Utils.ColorStateListFromIntColor(mColorPrimary));
chip.setChipStrokeWidth(2f);
mChipGroup.addView(chip);
}
}
}
最后在您的芯片组上设置检查更改的侦听器
mChipGroup.setOnCheckedChangeListener((group, checkedId) ->
mViewPagerGetStarted.setCurrentItem(checkedId,true));
样式.xml :
<style name="ChipTextStyle" parent="Widget.MaterialComponents.Chip.Choice">
<item name="android:textSize">13sp</item>
<item name="android:textColor">@color/colorPrimary</item>
<item name="android:padding">5dp</item>
<item name="checkedIconEnabled">false</item>
<item name="checkedIcon">@null</item>
<item name="closeIconTint">@color/colorPrimary</item>
</style>
