这是XML:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
style="@style/LightStyle"
android:layout_width="fill_parent"
android:layout_height="55dip"
android:clickable="true"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" />
</RelativeLayout>
如何以编程方式设置样式属性?
对于一个新的按钮/TextView:
Button mMyButton = new Button(new ContextThemeWrapper(this, R.style.button_disabled), null, 0);
对于已存在的实例:
mMyButton.setTextAppearance(this, R.style.button_enabled);
对于图像或布局:
Image mMyImage = new ImageView(new ContextThemeWrapper(context, R.style.article_image), null, 0);
我在我的复合ViewGroup中使用XML定义的视图,将它们添加到ViewGroup中。这样我就不能动态地更改样式,但是我可以进行一些样式自定义。我的组合:
public class CalendarView extends LinearLayout {
private GridView mCalendarGrid;
private LinearLayout mActiveCalendars;
private CalendarAdapter calendarAdapter;
public CalendarView(Context context) {
super(context);
}
public CalendarView(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onFinishInflate() {
super.onFinishInflate();
init();
}
private void init() {
mCalendarGrid = (GridView) findViewById(R.id.calendarContents);
mCalendarGrid.setNumColumns(CalendarAdapter.NUM_COLS);
calendarAdapter = new CalendarAdapter(getContext());
mCalendarGrid.setAdapter(calendarAdapter);
mActiveCalendars = (LinearLayout) findViewById(R.id.calendarFooter);
}
}
在XML视图中,我可以指定样式:
<com.mfitbs.android.calendar.CalendarView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/calendar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:orientation="vertical"
>
<GridView
android:id="@+id/calendarContents"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<LinearLayout
android:id="@+id/calendarFooter"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
/>
