1.引用库

implementation 'com.contrarywind:Android-PickerView:4.1.9'

2. 实现逻辑

public class TimeSelectDialog {
    private Activity activity;
    private ViewGroup contentView;
    private View view;
    private WheelView wvHour;
    private WheelView wvMinute;
    private List<String> hourList;
    private List<String> minuteList;
 
    public TimeSelectDialog(Activity activity) {
        this.activity = activity;
        contentView = activity.findViewById(android.R.id.content);
        view = LayoutInflater.from(activity).inflate(R.layout.dialog_time_select, null);
         wvHour = view.findViewById(R.id.wv_hour);
         wvMinute = view.findViewById(R.id.wv_minute);
        TextView tvCancel = view.findViewById(R.id.tv_cancel);
        TextView tvSure = view.findViewById(R.id.tv_sure);
        tvCancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        tvSure.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        initHourWheelView();
        initMinuteWheelView();
    }
 
    /**
     * 小时
     */
    private void initHourWheelView() {
        hourList = new ArrayList<>();
        for (int i = 0; i < 24; i++) {
            hourList.add(i+"时");
        }
 
        ArrayWheelAdapter hourAdapter = new ArrayWheelAdapter(hourList);
        wvHour.setAdapter(hourAdapter);
        wvHour.setCyclic(true); //取消循环显示数据
        wvHour.setCurrentItem(0); //当前显示第一条
        wvHour.setItemsVisibleCount(5); //可见范围为5个
        wvHour.setOnItemSelectedListener(new OnItemSelectedListener() {
            @SuppressLint("SetTextI18n")
            @Override
            public void onItemSelected(int index) {
            
            }
        });
    }
 
    /**
     * 分时
     */
    private void initMinuteWheelView() {
        minuteList = new ArrayList<>();
        for (int i = 0; i < 60; i++) {
            minuteList.add(i+"分");
        }
 
        ArrayWheelAdapter minuteAdapter = new ArrayWheelAdapter(minuteList);
        wvMinute.setAdapter(minuteAdapter);
        wvMinute.setCyclic(true); //取消循环显示数据
        wvMinute.setCurrentItem(0); //当前显示第一条
        wvMinute.setItemsVisibleCount(5); //可见范围为5个
        wvMinute.setOnItemSelectedListener(new OnItemSelectedListener() {
            @SuppressLint("SetTextI18n")
            @Override
            public void onItemSelected(int index) {
               
            }
        });
    }
 
    /**
     * 显示dialog(包含动画)
     */
    public void show(OnDismissListener onDismissListener) {
        this.onDismissListener = onDismissListener;
        Animation animation = AnimationUtils.loadAnimation(activity, R.anim.dialog_user_gender_in_anim);
        view.setAnimation(animation);
        contentView.addView(view);
    }
 
    /**
     * 移除dialog(包含动画)
     */
    public void dismiss() {
        Animation animation = AnimationUtils.loadAnimation(activity, R.anim.dialog_user_gender_out_anim);
        view.setAnimation(animation);
        contentView.removeView(view);
        if (onDismissListener != null) {
            onDismissListener.onDismiss(null);
        }
    }
 
    private OnDismissListener onDismissListener;
 
    public void setOnDismissListener(OnDismissListener onDismissListener) {
        this.onDismissListener = onDismissListener;
    }
 
    public interface OnDismissListener {
        void onDismiss(String timeStr);
    }
}

 2.布局实现 dialog_time_select.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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="match_parent"
    android:background="#80000000">
 
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:orientation="vertical"
        android:background="@android:color/white"
        android:paddingStart="40dp"
        android:paddingTop="20dp"
        android:paddingEnd="40dp"
        android:paddingBottom="20dp">
 
        <TextView

            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginBottom="30dp"
            android:text="自定义时间"
            android:textColor="@android:color/black"
            android:textSize="24sp"
            android:textStyle="bold"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />
 
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:background="@android:color/white"
            android:orientation="horizontal"
            android:paddingTop="30dp">
 
            <com.contrarywind.view.WheelView
                android:id="@+id/wv_hour"

                android:layout_height="match_parent"
                android:layout_weight="1" />
 
            <com.contrarywind.view.WheelView
                android:id="@+id/wv_minute"
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:layout_weight="1" />
 
        </LinearLayout>
 
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginTop="20dp"
            android:orientation="horizontal">
 
            <TextView
                android:id="@+id/tv_cancel"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:gravity="center"
                android:paddingStart="60dp"
                android:paddingTop="15dp"
                android:paddingEnd="60dp"
                android:paddingBottom="15dp"
                android:background="@android:color/darker_gray"
                android:text="关闭"
                android:textColor="#ffb300"
                android:textSize="18sp" />
 
            <TextView
                android:id="@+id/tv_sure"
                android:layout_width="wrap_content"

                android:textSize="18sp" />
        </LinearLayout>
    </LinearLayout>
</FrameLayout>

3.dialog动画

dialog_in_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromYDelta="100%p"
        android:toYDelta="0%p" />
</set>

dialog_out_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="300"
        android:fromYDelta="0%p"
        android:toYDelta="100%p" />
</set>

4.时间选择器弹框：

new TimeSelectDialog(activity).show(null);
