里面的片段自定义数字选择器 [英] Custom number picker inside fragment
本文介绍了里面的片段自定义数字选择器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
请帮我用 NumberPicker
通过 HTTPS ://github.com/SimonVT/android-numberpicker 。
我里面,我有按钮片段。点击按钮后,我想告诉我的号码选择器(如弹出,没有新画面)。
所以我做了什么:
我创建 NumberPickerCustomDialog
public class NumberPickerCustomDialog extends DialogFragment {
Context context;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// get context
context = getActivity().getApplicationContext();
// make dialog object
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// get the layout inflater
LayoutInflater li = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// inflate our custom layout for the dialog to a View
View view = li.inflate(R.layout.activity_dark, null);
// inform the dialog it has a custom View
builder.setView(view);
// and if you need to call some method of the class
NumberPicker np = (NumberPicker) view
.findViewById(R.id.numberPicker);
// create the dialog from the builder then show
return builder.create();
}
}
现在,在我的片段,点击按钮后,我试图表明我的号码选择器:
And now in my fragment, after clicking the button I try to show my number picker:
FragmentManager fm = getFragmentManager();
NumberPickerCustomDialog yourDialog = new NumberPickerCustomDialog();
yourDialog.show(fm, "some_optional_tag");
我的布局看起来:
My layout looks:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:gravity="center">
<net.simonvt.numberpicker.NumberPicker
android:id="@+id/numberPicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
我包括进库项目,复制布局和遇到错误:
I included library into project, copied layouts and got error:

我在做什么错了?
What am I doing wrong?
推荐答案
好吧,我解决了这个问题。该库需要定义样式,即:
Ok, I solved the problem. This library requires defining styles, i.e.:
<style name="SampleTheme" parent="android:Theme">
<item name="numberPickerStyle">@style/NPWidget.Holo.NumberPicker</item>
</style>
<style name="SampleTheme.Light" parent="android:Theme.Light">
<item name="numberPickerStyle">@style/NPWidget.Holo.Light.NumberPicker</item>
</style>
和在AndroidManifest.xml中,风格必须为活动的,要使用你的自定义数字选择器来定义:
and in AndroidManifest.xml, style must be defined for activity, where you want to use your custom number picker:
<activity android:name=".Activity"
android:theme="@style/SampleTheme.Light">
</activity>
