Android实现年月选择器功能-技术圈

开发过程中，年月的选择功能还是比较常见的，像这种功能点比较常见，要是每次都要自己手动去写，这无疑会耗费比较多的时间与精力，今天给大家介绍一个第三方库，使用该库来完成年月选择器功能。

一、效果图

二、实现步骤：

1、依赖库

implementation 'cn.aigestudio.wheelpicker:WheelPicker:1.1.3'

2、xml布局文件

<?xml version="1.0" encoding="utf-8"?><android.support.constraint.ConstraintLayout 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="200dp"    android:background="#ffffff">
    <TextView        android:id="@+id/cancel"        android:layout_width="60dp"        android:layout_height="40dp"        android:gravity="center"        android:text="取消"        android:textColor="#666666"        android:textSize="17sp"        app:layout_constraintLeft_toLeftOf="parent"        app:layout_constraintTop_toTopOf="parent" />
    <TextView        android:id="@+id/ok"        android:layout_width="60dp"        android:layout_height="40dp"        android:gravity="center"        android:text="确定"        android:textColor="#3C76FF"        android:textSize="17sp"        app:layout_constraintRight_toRightOf="parent"        app:layout_constraintTop_toTopOf="parent" />
    <View        android:id="@+id/view_line"        android:layout_width="match_parent"        android:layout_height="1dp"        android:background="#e5e5e5"        app:layout_constraintLeft_toLeftOf="parent"        app:layout_constraintTop_toBottomOf="@id/cancel" />
    <com.aigestudio.wheelpicker.WheelPicker        android:id="@+id/mWheelPicker_1"        android:layout_width="0dp"        android:layout_height="0dp"        android:layout_marginLeft="30dp"        app:layout_constraintBottom_toBottomOf="parent"        app:layout_constraintLeft_toLeftOf="parent"        app:layout_constraintRight_toLeftOf="@id/mWheelPicker_2"        app:layout_constraintTop_toBottomOf="@id/view_line"        app:wheel_atmospheric="true"        app:wheel_curtain_color="#1886F7"        app:wheel_curved="true"        app:wheel_cyclic="true"        app:wheel_indicator_color="#e5e5e5"        app:wheel_item_text_color="#919191"        app:wheel_item_text_size="23sp"        app:wheel_selected_item_text_color="#000000" />
    <com.aigestudio.wheelpicker.WheelPicker        android:id="@+id/mWheelPicker_2"        android:layout_width="0dp"        android:layout_height="0dp"        android:layout_marginRight="30dp"        app:layout_constraintBottom_toBottomOf="parent"        app:layout_constraintLeft_toRightOf="@id/mWheelPicker_1"        app:layout_constraintRight_toRightOf="parent"        app:layout_constraintTop_toTopOf="@id/mWheelPicker_1"        app:wheel_atmospheric="true"        app:wheel_curtain_color="#1886F7"        app:wheel_curved="true"        app:wheel_cyclic="true"        app:wheel_indicator_color="#e5e5e5"        app:wheel_indicator_size="24sp"        app:wheel_item_text_color="#919191"        app:wheel_item_text_size="23sp"        app:wheel_selected_item_text_color="#000000" />
</android.support.constraint.ConstraintLayout>

3、添加数据

 List<String> CEOYEAR = new ArrayList<>(); List<String> CEOMONTH = new ArrayList<>();
  for (int i = 2000; i < 2051; i++) {     CEOYEAR.add(i + "");  }
  for (int i = 1; i < 13; i++) {     CEOMONTH.add(i + "");  }

4、设置选择器弹出框

    /**     * @desc : 两个滚动器     **/    private void showTwoWheelPicker(Context context, final List<String> data1, final List<String> data2, final TwoWheelListener mTwoWheelListener) {
        final Dialog dialog = getDialog(context);        Window window = dialog.getWindow();        window.setGravity(Gravity.BOTTOM);        window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);        window.setContentView(R.layout.fragment_sami);
        final WheelPicker wv1 = window.findViewById(R.id.mWheelPicker_1);        final WheelPicker wv2 = window.findViewById(R.id.mWheelPicker_2);
        wv1.setData(data1);        wv2.setData(data2);
        //取消        window.findViewById(R.id.cancel).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                dialog.dismiss();            }        });
        //确定        window.findViewById(R.id.ok).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                dialog.dismiss();
                if (mTwoWheelListener != null) {                    mTwoWheelListener.onOk(data1.get(wv1.getCurrentItemPosition()), data2.get(wv2.getCurrentItemPosition()));                }            }        });    }
    private Dialog getDialog(Context context) {
        return new AlertDialog.Builder(context, R.style.RoundCornerDialog).setCancelable(false).show();    }
    private TwoWheelListener mTwoWheelListener = null;
    public static interface TwoWheelListener {        void onOk(String str1, String str2);    }

5、设置弹出框dialog样式

 <!--圆角的dialog样式-->    <style name="RoundCornerDialog" parent="@android:style/Theme.Dialog">        <item name="android:windowFrame">@null</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowIsTranslucent">true</item>        <item name="android:windowNoTitle">true</item>        <item name="android:background">@android:color/transparent</item>        <item name="android:windowBackground">@android:color/transparent</item>        <item name="android:backgroundDimEnabled">true</item>        <item name="android:backgroundDimAmount">0.6</item></style>

6、设置点击事件弹出

 findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                showTwoWheelPicker(AppBarLayoutActivity.this, CEOYEAR, CEOMONTH, new TwoWheelListener() {                    @Override                    public void onOk(String str1, String str2) {                        Toast.makeText(AppBarLayoutActivity.this, str1 + "年" + str2 + "日", Toast.LENGTH_SHORT).show();                    }                });            }        });
