gridview并不完整match_parent,因为在gridview的右侧有一个白色的小空间。如何删除这个很小的空白?示例:http://prntscr.com/ofa94t
我用于gridview的布局:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="@+id/layout_days"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#007399"
android:orientation="horizontal"
android:paddingTop="4dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="10dp"
android:paddingBottom="4dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_weight="1"
android:gravity="center"
android:text="Zon"
android:textColor="@android:color/white"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_weight="1"
android:gravity="center"
android:text="Man"
android:textColor="@android:color/white"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_weight="1"
android:gravity="center"
android:text="Din"
android:textColor="@android:color/white"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_weight="1"
android:gravity="center"
android:text="Woe"
android:textColor="@android:color/white"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_weight="1"
android:gravity="center"
android:text="Don"
android:textColor="@android:color/white"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_weight="1"
android:gravity="center"
android:text="Vrij"
android:textColor="@android:color/white"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_weight="1"
android:gravity="center"
android:text="Zat"
android:textColor="@android:color/white"
android:textStyle="bold" />
</LinearLayout>
<GridView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/gridview"
android:stretchMode="columnWidth"
android:gravity="center_horizontal"
android:numColumns="7"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginBottom="10dp"/>
</LinearLayout>
我的适配器,我可以在其中拉伸视图的高度,但不能拉伸宽度:
@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
Date monthDate = dates.get(position);
Calendar dateCalendar = Calendar.getInstance();
dateCalendar.setTime(monthDate);
int parentHeight= parent.getHeight();
int DayNo = dateCalendar.get(Calendar.DAY_OF_MONTH);
int displayMonth = dateCalendar.get(Calendar.MONTH) + 1;
int displayYear = dateCalendar.get(Calendar.YEAR);
int currentMonth = currentDate.get(Calendar.MONTH) +1;
int currentYear = currentDate.get(Calendar.YEAR);
View view = convertView;
if (view == null) {
view = inflater.inflate(R.layout.layout_singleview_calendar, parent, false);
}
if (displayMonth == currentMonth && displayYear == currentYear) {
view.setBackgroundColor(getContext().getResources().getColor(R.color.green));
} else {
view.setBackgroundColor(Color.parseColor("#ffffff"));
}
TextView Day_Number = view.findViewById(R.id.calendar_day);
Day_Number.setText(String.valueOf(DayNo));
view.setMinimumHeight(parentHeight/6);
return view;
}
我发现了这个Android GridView imperfection, how to remove extra white space to the right,但似乎没有任何作用。
答案 0 :(得分:2)
从“网格”视图中删除左,右页边距,
或
您可以制作单独的网格视图单元格布局,使其仅包含一个日历单元格,而其他XML活动包含网格视图,然后从Java类中获取它,如下所示
***** gridview.xml *****
<GridView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/gridview"
android:numColumns="7">
</GridView>
**** gridview_layout.xml ****
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/lr1"
android:layout_width="match_parent"
android:layout_height="@dimen/margin_45dp"
android:orientation="vertical">
<TextView
android:id="@+id/calendar_day"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="1"
android:textColor="@color/primary_black_text"
android:textSize="13sp"
android:textStyle="bold">
</TextView>
<TextView
android:id="@+id/events_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textColor="@color/accent"
android:textSize="9sp"
android:textStyle="bold" />
**** Java文件****
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Date monthDate = dates.get(position);
Date today = new Date(); //*******
Calendar dateCalendar = Calendar.getInstance();
dateCalendar.setTime(monthDate);
int DayNo = dateCalendar.get(Calendar.DAY_OF_MONTH);
int displayMonth = dateCalendar.get(Calendar.MONTH) + 1;
int displayYear = dateCalendar.get(Calendar.YEAR);
View view = convertView;
if (view == null)
view = inflater.inflate(R.layout.calendar_cell_layout, parent, false);
if (monthDate.getMonth() != today.getMonth() || monthDate.getYear() != today.getYear()) {
TextView myTv = view.findViewById(R.id.calendar_day);
myTv.setTextColor(getContext().getResources().getColor(R.color.secondary_text));
} else if (monthDate.getDate() == today.getDate()) {
TextView myTv = view.findViewById(R.id.calendar_day);
myTv.setBackground(getContext().getDrawable(R.drawable.roundshape));
myTv.setTextColor(getContext().getColor(R.color.icons));
}
TextView Day_Number = view.findViewById(R.id.calendar_day);
TextView EventNumber = view.findViewById(R.id.events_id);
Day_Number.setText(String.valueOf(DayNo));
Calendar eventCalendar = Calendar.getInstance();
ArrayList<String> arrayList = new ArrayList<>();
for (int i = 0; i < events.size(); i++) {
eventCalendar.setTime(ConvertStringToDate(events.get(i).getDATE()));
if (DayNo == eventCalendar.get(Calendar.DAY_OF_MONTH)
&& displayMonth == eventCalendar.get(Calendar.MONTH) + 1
&& displayYear == eventCalendar.get(Calendar.YEAR))
{
arrayList.add(events.get(i).getEVENT());
EventNumber.setText(arrayList.size() + " Events");
EventNumber.setBackgroundColor(000000);
}
}
return view;
}
希望这对您有帮助!谢谢!
