When using the Android simulator, found that the AVD you created did not appear on the side of the keyboard, after searching the internet, found that many people have this problem, there are also articles that directly use the keyboard on the PC, because there are corresponding shortcut keys. However, no keyboard, always uncomfortable!

The cause of the problem is the skin option when customizing the AVD, because I just started with: QVGA so no, then choose WVGA800.
VGA: Video graphics Array, that is: Display the drawing matrix, equivalent to 640x480 pixels;
HVGA: Half-size VGA, that is: half of the VGA, the resolution is 480x320, like the Samsung Galaxy S5830 is the use of this resolution ;
QVGA: Quarter VGA, that is: VGA One-fourth, the resolution of the video, generally used for small-screen mobile phone like Samsung's furious mini S5570 is the use of this resolution ;
< Span style= "font-size:18px" >WQVGA : Wide Quarter VGA, ie: expanded QVGA, higher resolution than QVGA, Lower than VGA, generally: 400x240,480x272;
WVGA : Wide Video Graphics Array, i.e.: enlarged VGA, The resolution is 800x480 pixels, ;
FWVGA : Full Wide VGA, Digital Product screen material, another form of VGA, higher than WVGA resolution, alias: Full Wide VGA, with a resolution of 854x480 pixels (16:9).
