1.在Dialogfragment和NumberPickerView的配合下，我得到了这样的效果：

2.导入依赖.此依赖的github地址 https://github.com/Carbs0126/NumberPickerView/tree/master/app
compile 'cn.carbswang.android:NumberPickerView:1.1.1'
3.定义一个dialog继承fragmentDialog,并重写onCreateView方法。
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
getDialog().requestWindowFeature(STYLE_NO_TITLE);//去掉title，是为了在布局里面自定义title
View view=inflater.inflate(R.layout.ll,null);
ButterKnife.bind(this,view);//使用注解
picker.setOnValueChangedListener(this);//监听选中状态
picker.setDisplayedValues(getResources().getStringArray(R.array.minute_display));
picker.setMaxValue(59);
picker.setMinValue(0);
picker.setValue(10);
picker2.setOnValueChangedListener(this);
String[] units = {"kg","inch"};
picker2.setDisplayedValues(units);
picker2.setMaxValue(units.length-1);
picker2.setMinValue(0);
picker2.setValue(0);
return view;
}
4.看一下布局文件,里面主要是两个NumberPickerView。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
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"
tools:context="com.example.jyj.dialogtest.MainActivity">
<TextView
android:id="@+id/time"
android:text="时间选择"
android:layout_centerHorizontal="true"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_weight="1" />
<LinearLayout
android:id="@+id/picker_ll"
android:layout_below="@+id/time"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<cn.carbswang.android.numberpickerview.library.NumberPickerView
android:layout_weight="1"
android:id="@+id/picker"
android:layout_width="wrap_content"
android:layout_height="240dp"
android:layout_centerHorizontal="true"
android:background="#11333333"
android:contentDescription="test_number_picker_view"
app:npv_ItemPaddingHorizontal="5dp"
app:npv_ItemPaddingVertical="5dp"
app:npv_ShowCount="5"
app:npv_RespondChangeOnDetached="false"
app:npv_TextSizeNormal="16sp"
app:npv_TextSizeSelected="20sp"
app:npv_WrapSelectorWheel="true"/>
<cn.carbswang.android.numberpickerview.library.NumberPickerView
android:layout_weight="1"
android:id="@+id/picker2"
android:layout_width="wrap_content"
android:layout_height="240dp"
android:layout_centerHorizontal="true"
android:background="#11333333"
android:contentDescription="test_number_picker_view"
app:npv_ItemPaddingHorizontal="5dp"
app:npv_ItemPaddingVertical="5dp"
app:npv_ShowCount="5"
app:npv_RespondChangeOnDetached="false"
app:npv_TextSizeNormal="16sp"
app:npv_TextSizeSelected="20sp"
app:npv_WrapSelectorWheel="true"/>
</LinearLayout>
<LinearLayout
android:layout_below="@+id/picker_ll"
android:layout_width="match_parent"
android:layout_height="50dp">
<Button
android:id="@+id/cancle"
android:background="@null"
android:gravity="center"
android:layout_weight="1"
android:text="取消"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
<Button
android:id="@+id/confirm"
android:background="@null"
android:gravity="center"
android:layout_weight="1"
android:text="确定"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
</LinearLayout>
</RelativeLayout>
5.上面第三步所需要的数组。
在Strings里面的string-array数组。
<string-array name="minute_display">
<item>0</item>
<item>1</item>
<item>2</item>
<item>3</item>
<item>4</item>
<item>5</item>
<item>6</item>
<item>7</item>
<item>8</item>
<item>9</item>
<item>10</item>
<item>11</item>
<item>12</item>
<item>13</item>
<item>14</item>
<item>15</item>
<item>16</item>
<item>17</item>
<item>18</item>
<item>19</item>
<item>20</item>
<item>21</item>
<item>22</item>
<item>23</item>
<item>24</item>
<item>25</item>
<item>26</item>
<item>27</item>
<item>28</item>
<item>29</item>
<item>30</item>
<item>31</item>
<item>32</item>
<item>33</item>
<item>34</item>
<item>35</item>
<item>36</item>
<item>37</item>
<item>38</item>
<item>39</item>
<item>40</item>
<item>41</item>
<item>42</item>
<item>43</item>
<item>44</item>
<item>45</item>
<item>46</item>
<item>47</item>
<item>48</item>
<item>49</item>
<item>50</item>
<item>51</item>
<item>52</item>
<item>53</item>
<item>54</item>
<item>55</item>
<item>56</item>
<item>57</item>
<item>58</item>
<item>59</item>
</string-array>
6.获得选中的值
@Override
public void onValueChange(NumberPickerView picker, int oldVal, int newVal) {
switch (picker.getId()){
case R.id.picker:
Log.e("AAA","===oldVal===="+oldVal+"===newVal=="+newVal);
this.newVal=newVal;
break;
case R.id.picker2:
Log.e("AAA","===oldVal===="+oldVal+"===newVal=="+newVal);
String newString=picker.getDisplayedValues()[newVal];
Log.e("AAA","==保存=newString===="+newString);
}
}
7.在activity里面调用一下就好
@OnClick(R.id.showDialog)
public void showDialog(){
new MyDialog().show(getFragmentManager(),"dialogFragment");
}
