Could I force switching portrait/landscape view on emulator?

Could I f开发者_运维百科orce changing the view's orientation in order to test how the layout appears or it is not possible to test this behavior on virtual device.

Under forcing it, I mean for example on click event to change from one to another screen orientation and inverse.

Ctrl+F11 will switch the screen orientation, but when it come to coding the orientation to change you have a couple of options:

• Hardcode the Activity to be a given orientation. Which is useful when you want to force the user to use a specific orientation only.
• Set the Activity to allow either orientation and let the user decide.

Each of these is useful in their own scenarios. For example, viewing a graph that will only be useful in landscape should be hardcoded, but scrolling through a list could allow a user to pick which was more comfortable for them.

How to set the mode:

• In Eclipse go to the AndroidManifest->Application Tab, Select the Activity you want to edit and set the Screen Orientation directly.
• In AndroidManifest.xml: <activity android:screenOrientation="[fill in preference here]" />
• In code: Activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_[type])
• To get the current orientation in code:
  Activity.getRequestedOrientation()

An explanation of the different modes can be found here: Screen Orientation Types | Activity

So, if you want to force a change on a screen based on user input, you can all you need to do is set the orientation type in code.

This is done with the HOME(7) button on the num pad (num lock needs to be disabled i beleve, not sure tho).

Did you try Ctrl+F11 keyboard shortcut or as the user dragon112 has suggested you can go for numpad key "7" with numlock "on".
