답변:
우리가 필요한 것은 다음과 같습니다 ViewPager , TabLayout 및 선택 및 기본 점 2 드로어 블.
먼저 TabLayout
화면 레이아웃 에 추가 하고로 연결해야합니다 ViewPager
. 우리는 두 가지 방법으로 이것을 할 수 있습니다 :
TabLayout
에ViewPager
<androidx.viewpager.widget.ViewPager
android:id="@+id/photos_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.tabs.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</androidx.viewpager.widget.ViewPager>
이 경우
TabLayout
자동으로 (으)로 연결ViewPager
되지만TabLayout
그 옆이 아니라 옆에ViewPager
있습니다.
TabLayout
<androidx.viewpager.widget.ViewPager
android:id="@+id/photos_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<com.google.android.material.tabs.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
이 경우
TabLayout
어디든지 넣을 수 있지만 프로그래밍 방식 으로 연결TabLayout
해야ViewPager
합니다
ViewPager pager = (ViewPager) view.findViewById(R.id.photos_viewpager);
PagerAdapter adapter = new PhotosAdapter(getChildFragmentManager(), photosUrl);
pager.setAdapter(adapter);
TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tab_layout);
tabLayout.setupWithViewPager(pager, true);
레이아웃을 만든 후에는 점을 준비해야합니다. 따라서 우리는 selected_dot.xml
, default_dot.xml
및라는 세 개의 파일을 만듭니다 tab_selector.xml
.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:innerRadius="0dp"
android:shape="ring"
android:thickness="8dp"
android:useLevel="false">
<solid android:color="@color/colorAccent"/>
</shape>
</item>
</layer-list>
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:innerRadius="0dp"
android:shape="ring"
android:thickness="8dp"
android:useLevel="false">
<solid android:color="@android:color/darker_gray"/>
</shape>
</item>
</layer-list>
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/selected_dot"
android:state_selected="true"/>
<item android:drawable="@drawable/default_dot"/>
</selector>
이제 TabLayout
XML 레이아웃에 3 줄의 코드 만 추가하면됩니다 .
app:tabBackground="@drawable/tab_selector"
app:tabGravity="center"
app:tabIndicatorHeight="0dp"
ViewPager2
이 기사 를 읽으려면 :
medium.com에 도트 표시기가 있는 ViewPager (2)
투표는 환영합니다 ;-)
app:tabMaxWidth
에서 사용할 수 있습니다
app:tabMaxWidth="30dp" app:tabTextColor="@color/transparent2" app:tabSelectedTextColor="@color/transparent2" app:tabIndicatorHeight="0dp" android:layout_gravity="bottom|center"
먼저 View Pager 위에 표시되는 도트에 대한 LinerLayout을 제공하는 레이아웃을 만듭니다.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<LinearLayout
android:id="@+id/pager_dots"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="10dp"
android:background="@android:color/transparent"
android:gravity="center_horizontal"
android:orientation="horizontal">
</LinearLayout>
</RelativeLayout>
그 후 2 개의 드로어 블을 만듭니다.
1. 선택되지 않은 드로어 블
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="oval" xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/transparent"/>
<size android:width="12dp" android:height="12dp"/>
<stroke android:width="1dp" android:color="#ffffff"/>
</shape>
2. 선택된 드로어 블
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="oval" xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@android:color/transparent"/>
<size android:width="12dp" android:height="12dp"/>
<stroke android:width="1dp" android:color="#000000"/>
</shape>
그 세트 어댑터 후
private LinearLayout llPagerDots;
private ViewPager viewPager;
private ArrayList<String> eventImagesUrl;
private HomeViewPagerAdapter homeViewPagerAdapter;
private ImageView[] ivArrayDotsPager;
public void setUpViewPager() {
viewPager = (ViewPager) findViewById(R.id.view_pager);
llPagerDots = (LinearLayout) findViewById(R.id.pager_dots);
homeViewPagerAdapter = new HomeViewPagerAdapter(mContext, eventImagesUrl);
viewPager.setAdapter(homeViewPagerAdapter);
setupPagerIndidcatorDots();
ivArrayDotsPager[0].setImageResource(R.drawable.page_indicator_selected);
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
for (int i = 0; i < ivArrayDotsPager.length; i++) {
ivArrayDotsPager[i].setImageResource(R.drawable.page_indicator_unselected);
}
ivArrayDotsPager[position].setImageResource(R.drawable.page_indicator_selected);
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
setupPagerIndidcatorDots () 메소드를 작성하십시오.
private void setupPagerIndidcatorDots() {
ivArrayDotsPager = new ImageView[eventImagesUrl.size()];
for (int i = 0; i < ivArrayDotsPager.length; i++) {
ivArrayDotsPager[i] = new ImageView(getActivity());
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.setMargins(5, 0, 5, 0);
ivArrayDotsPager[i].setLayoutParams(params);
ivArrayDotsPager[i].setImageResource(R.drawable.page_indicator_unselected);
//ivArrayDotsPager[i].setAlpha(0.4f);
ivArrayDotsPager[i].setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
view.setAlpha(1);
}
});
llPagerDots.addView(ivArrayDotsPager[i]);
llPagerDots.bringToFront();
}
HomeViewPagerAdapter
입니까?
내 라이브러리를 확인하여 요청을 처리 할 수 있습니다 : https://github.com/tommybuonomo/dotsindicator
XML 레이아웃에서
<com.tbuonomo.viewpagerdotsindicator.DotsIndicator
android:id="@+id/dots_indicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
app:dotsColor="@color/colorPrimary"
app:dotsSize="16dp"
app:dotsWidthFactor="3"
/>
자바 코드에서
dotsIndicator = (DotsIndicator) findViewById(R.id.dots_indicator);
viewPager = (ViewPager) findViewById(R.id.view_pager);
adapter = new ViewPagerAdapter();
viewPager.setAdapter(adapter);
dotsIndicator.setViewPager(viewPager);
tools:replace="android:label"
하려면 application
태그를 태그에 추가 해야했습니다 AndroidManifest.xml
.
gradle

SmartViewPager
당신의 커스텀 뷰일 것 입니다.
최신 ViewPager2 및 Kotlin으로 이와 비슷한 것을 원할 때
모든 것이 자기 설명 적이므로 설명 할 필요가 없습니다!
1. 활동 또는 파편
val imageList = listOf(
ImageModel(R.drawable.offer1),
ImageModel(R.drawable.splash),
ImageModel(R.drawable.offer1),
ImageModel(R.drawable.splash2)
)
val adapter = HomeOffersAdapter()
adapter.setItem(imageList)
photos_viewpager.adapter = adapter
TabLayoutMediator(tab_layout, photos_viewpager) { tab, position ->
}.attach()
}
2. 레이아웃
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="@dimen/dp_200">

<item android:drawable="@drawable/dot_selected" android:state_selected="true" />
<item android:drawable="@drawable/dot_default" />
4. 드로어 블 : dot_selected.xml

class HomeOffersAdapter : RecyclerView.Adapter<HomeOffersAdapter.HomeOffersViewHolder>() {
private var list: List<ImageModel> = listOf()
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): HomeOffersViewHolder {
return HomeOffersViewHolder(parent)
}
override fun onBindViewHolder(holder: HomeOffersViewHolder, position: Int) {
holder.bind(list[position])
}
fun setItem(list: List<ImageModel>) {
this.list = list
notifyDataSetChanged()
}
override fun getItemCount(): Int = list.size
class HomeOffersViewHolder constructor(itemView: View) : RecyclerView.ViewHolder(itemView) {
constructor(parent: ViewGroup) : this(
LayoutInflater.from(parent.context).inflate(
R.layout.pager_item,
parent, false
)
)
fun bind(imageModel: ImageModel) {
itemView.offerImage.setImageResource(imageModel.image)
}
}
}
7. 레이아웃 : pager_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

ViewFlipper와 viewFlipper_linear_dot_lay (Linearlayout)을 동일한 기준선에 놓고 아래 중 하나를 따르십시오.
viewFlipper_linear_dot_lay= (LinearLayout) findViewById(R.id.dots_lay);
setupDotsOnViewPager(images_viewFlipper);
for (int i = 0; i < images_viewFlipper.size(); i++) {
//Add Images to ViewFlipper
}
private void setupDotsOnViewPager(ArrayList images_viewFlipper) {
images_linear = new ImageView[images_viewFlipper.size()];
for (int i = 0; i < images_linear.length; i++) {
images_linear[i] = new ImageView(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.setMargins(5, 0, 5, 0);
params.gravity = Gravity.BOTTOM | Gravity.CENTER;
images_linear[i].setLayoutParams(params);
images_linear[i].setImageResource(R.drawable.unselected);
viewFlipper_linear_dot_lay.addView(images_linear[i]);
viewFlipper_linear_dot_lay.bringToFront();
}
}
그리고 OnRight & OnLeft getsures는 아래 코드를 배치합니다
for (int i = 0; i < images_linear.length; i++) {
images_linear[i].setImageResource(R.drawable.unselected);
}
images_linear[viewFlipper.getDisplayedChild()].setImageResource(R.drawable.selected);
