Android如何實現年月選擇器功能
開發過程中,年月的選擇功能還是比較常見的,像這種功能點比較常見,要是每次都要自己手動去寫,這無疑會耗費比較多的時間與精力,今天給大傢介紹一個第三方庫,使用該庫來完成年月選擇器功能。
一、效果圖
二、實現步驟:
1、依賴庫
implementation 'cn.aigestudio.wheelpicker:WheelPicker:1.1.3'
2、xml佈局文件
<?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="確定" 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、添加數據
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、設置選擇器彈出框
/** * @desc : 兩個滾動器 **/ 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(); } }); //確定 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、設置彈出框dialog樣式
<!--圓角的dialog樣式--> <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、設置點擊事件彈出
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(); } }); } });
四、總結
這個第三方庫我這裡隻是做瞭簡單的介紹,還有更多需求的還是去閱讀第三方庫。
