Android地址(省市区)、日期、时间滚轮选择器简单封装

前言：

1.android开发中时间、日期、地址等滚轮选择器很常见，很多App会使用这种效果，收集了一下资料，于是自己做了一个简单封装，方便使用，感谢各位大佬的资料，效果如图:

2.使用方法代码如下:

public class MainActivity extends AppCompatActivity {
    private Dialog dateDialog, timeDialog, chooseDialog;
    private TextView mTextView;
    private List<String> list = new ArrayList<>();
    private ChooseAddressWheel chooseAddressWheel;
    private String address;
​
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        initWheel();
        initData();
    }

/**
 * 初始化控件
 */
private void initView() {
    mTextView = findViewById(R.id.textView);
    String[] data = getResources().getStringArray(R.array.list);
    list.addAll(Arrays.asList(data));
}
​
/**
 * 初始化地址
 */
private void initWheel() {
    chooseAddressWheel = new ChooseAddressWheel(this);
    chooseAddressWheel.setOnAddressChangeListener(new OnAddressChangeListener() {
        @Override
        public void onAddressChange(String province, String city, String district) {
            address = (province + " " + city + " " + district);
            mTextView.setText(address);
        }
    });
}
​
/**
 * 初始化数据
 */
private void initData() {
    String address = Utils.readAssert(this, "address.txt");
    AddressModel model = JsonUtil.parseJson(address, AddressModel.class);
    if (model != null) {
        AddressDetailsEntity data = model.Result;
        if (data == null) return;
        if (data.ProvinceItems != null && data.ProvinceItems.Province != null) {
            chooseAddressWheel.setProvince(data.ProvinceItems.Province);
            chooseAddressWheel.defaultValue(data.Province, data.City, data.Area);
        }
    }
}

/**
 * 选择其他
 * @param view
 */
public void btnOther(View view) {
    showChooseDialog(list);
}
​
/**
 * 选择时间
 * @param view
 */
public void btnTime(View view) {
    showTimePick();
}
​
/**
 * 选择日期
 * @param view
 */
public void btnDate(View view) {
    showDateDialog(DateUtil.getDateForString("2000-02-14"));
}
​
/**
 * 选择地址
 * @param view
 */
public void btnAddress(View view) {
    chooseAddressWheel.show(view);
}
​
/**
 * 显示其他列表
 */
private void showChooseDialog(List<String> mlist) {
    DataPickerDialog.Builder builder = new DataPickerDialog.Builder(this);
    chooseDialog = builder.setData(mlist).setSelection(1).setTitle("取消")
            .setOnDataSelectedListener(new DataPickerDialog.OnDataSelectedListener() {
                @Override
                public void onDataSelected(String itemValue, int position) {
                    mTextView.setText(itemValue);
                }
​
                @Override
                public void onCancel() {
​
                }
            }).create();
    chooseDialog.show();
}
​
​
/**
 * 显示日期
 * @param date
 */
private void showDateDialog(List<Integer> date) {
    DatePickerDialog.Builder builder = new DatePickerDialog.Builder(this);
    builder.setOnDateSelectedListener(new DatePickerDialog.OnDateSelectedListener() {
        @Override
        public void onDateSelected(int[] dates) {
            mTextView.setText(String.format("%d-%s-%s", dates[0], dates[1] > 9 ? dates[1] : ("0" + dates[1]), dates[2] > 9 ? dates[2] : ("0" + dates[2])));
        }
​
        @Override
        public void onCancel() {
​
        }
    })
            .setSelectYear(date.get(0) - 1)
            .setSelectMonth(date.get(1) - 1)
            .setSelectDay(date.get(2) - 1);
    builder.setMaxYear(DateUtil.getYear());
    builder.setMaxMonth(DateUtil.getDateForString(DateUtil.getToday()).get(1));
    builder.setMaxDay(DateUtil.getDateForString(DateUtil.getToday()).get(2));
    dateDialog = builder.create();
    dateDialog.show();
}
​
/**
 * 显示时间
 */
private void showTimePick() {
    if (timeDialog == null) {
        TimePickerDialog.Builder builder = new TimePickerDialog.Builder(this);
        timeDialog = builder.setOnTimeSelectedListener(new TimePickerDialog.OnTimeSelectedListener() {
            @Override
            public void onTimeSelected(int[] times) {
                mTextView.setText(String.format("%d:%d", times[0], times[1]));
            }
        }).create();
    }
    timeDialog.show();
}

3.布局代码如下:

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    android:padding="16dp">
​
    <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        app:layout_constraintTop_toTopOf="parent"
        android:text="显示选择内容"
        android:textSize="18sp"
        android:textColor="@color/white"
        android:gravity="center"
        android:background="@drawable/shape_bg"/>
​
    <Button
        android:id="@+id/btn_time"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/time"
        app:layout_constraintTop_toBottomOf="@id/textView"
        android:layout_marginTop="10dp"
        android:textSize="18sp"
        android:textColor="@color/white"
        android:background="@drawable/shape_bg"
        android:onClick="btnTime"/>
​
    <Button
        android:id="@+id/btn_date"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/date"
        android:textSize="18sp"
        android:textColor="@color/white"
        android:background="@drawable/shape_bg"
        app:layout_constraintTop_toBottomOf="@id/btn_time"
        android:layout_marginTop="10dp"
        android:onClick="btnDate"/>
​
    <Button
        android:id="@+id/btn_address"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/address"
        android:textSize="18sp"
        android:textColor="@color/white"

        app:layout_constraintTop_toBottomOf="@id/btn_date"
        android:layout_marginTop="10dp"
        android:onClick="btnAddress"/>
​
    <Button
        android:id="@+id/btn_other"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/other"
        android:textSize="18sp"
        android:textColor="@color/white"
        android:background="@drawable/shape_bg"
        app:layout_constraintTop_toBottomOf="@id/btn_address"
        android:layout_marginTop="10dp"
        android:onClick="btnOther"/>
