How to start a new activity when screen orientation changes? Android
I am writing an application which in portrait view has a gallery at the top and when you click a picture it will inflate and fill the entire screen.
This works however in landscape mode the gallery covers up most of the picture and it in general looks crappy.
I made a GridView for landscape mode. The problem I am having now is to change it from the gallery activity to the Gridview activity when the orientation changes. Any ideas?
Add this to your Activity:
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
startActivity(newActivity)
}
Note that this is a bad idea. Actually, it's a really bad idea. A much better alternative would be to either force one orientation or to create a layout that looks great on both orientations.
The right way to do it is to define two layouts, one in layout-port and one in layou-land directories. That is, you will have the following two layouts: res/layout-port/main.xml and res/layout-land/main.xml .
In your software you simply write secContentView(R.layout.main); and android will take care of applying the right layout upon device rotation.
为横向模式制作额外的布局xml文件并将其放入文件夹“layout-land”
