设置android模拟器每次启动都按一定比例显示

1) go to Run > Run Configurations... > (Select your application on the left hand side) > (Click the "Target" tab on the right hand side). 2) At the bottom there, you'll see 'Emulator launch parameters'. In the 'additional emulator command line options', add '-scale 0.75' (to make the screen 75% of full size)

Next time you start the emulator it will have scaled properly, hooray!
