About layout 1, do not use absolute Layout 2, try to use match_parent instead of fill_parent. 3, can use the weight of the place as far as possible the use of weight (android:layout_weight) 4, if it is a solid color background, as far as possible using the shape of Android custom. 5. If you need to fit at a specific resolution, you can create a new Layout-hxw.xml folder on the Res directory. For example, to fit the 1080*1800 screen (Meizu MX3 with this resolution), create a new Layout-1800x10

1. Several termsVGA, HVGA, QVGA, WVGA, WQVGAThese terms refer to the screen resolution.VGA: Video Graphics Array: displays the drawing matrix, which is equivalent to 640x480 pixels;HVGA: Half-size VGA; that is, Half of VGA, resolution: 480 × 320;QVGA: Quarter VGA; that is, 1/4 of VGA, resolution: 320 × 240;WVGA: Wide Video Graphics Array; that is, expanded VGA with a resolution of 800x480 pixels;

versus pixels:When using native drawing technologies such as quartz, uikit, and core animation, you specify coordinate values using a logical coordinate space, which measures distances in points. this logical coordinate system is decoupled from the device coordinate space used by the system frameworks to manage the pixels on the screen. generally, the size used in the program is calculated by point. in the old iPhone, point and pixel are hardly distinguished, because they are both and 320*
