小编Mar*_*tin的帖子

如果我创建一个新的XML文件(使用默认的Android Studio"创建线性布局"),Studio会生成一个包含内容的文件:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

</LinearLayout>

如果我(右) - 单击"分析...→检查代码",结果窗口将抛出2次:"命名空间未绑定"并引用第3行和第7行(LinearLayout-tags).它是Studio中的错误吗？

我从Android开发者那里获取了原始的TimePicker-Source

并将其粘贴到Android Studio中的新类中.Android Studio会抛出错误"修改程序'静态',此处不允许".怎么了？这是来源:

public static class TimePickerFragment extends DialogFragment
                        implements TimePickerDialog.OnTimeSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current time as the default values for the picker
        final Calendar c = Calendar.getInstance();
        int hour = c.get(Calendar.HOUR_OF_DAY);
        int minute = c.get(Calendar.MINUTE);

        // Create a new instance of TimePickerDialog and return it
        return new TimePickerDialog(getActivity(), this, hour, minute,
                DateFormat.is24HourFormat(getActivity()));
    }

    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        // Do something with the time chosen …
