（1）获取屏幕的尺寸
WindowManager windowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);Display d = windowManager.getDefaultDisplay();mWidth = d.getWidth();mHeight = d.getHeight();DisplayMetrics dm = getResources().getDisplayMetrics();mScreenDensity = dm.density;
（2）美工设计图的尺寸
uiWidth,uiHeight
（3）获取缩放比例
float scaleWidth = mWidth / uiWidth;float scaleHeight = mHeight/ uiHeight;
（4）所有布局的尺寸用代码实现
public static int getWidthSize(int size){ return (int) (size * scaleWidth);}public static int getHightSize(int size){ return (int) (size * scaleHeight);}public static float getTextSize(int pxSize){ return (pxSize*scaleHeight) / mScreenDensity;}public static void setViewSize(int width, int height, View v){ int paramWidth = getWidthSize(width); int paramHeight = getHightSize(height); ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) v.getLayoutParams(); if (width != INVALID){ params.width = paramWidth; } if (height != INVALID){ params.height = paramHeight; } v.setLayoutParams(params);}public static void setViewPadding(int left, int top, int right, int bottom, View v){ left = getWidthSize(left); top = getHightSize(top); right = getWidthSize(right); bottom = getWidthSize(bottom); v.setPadding(left, top, right, bottom);}public static void setViewMargin(int left, int top, int right, int bottom, View v){ int paramLeft = getWidthSize(left); int paramTop = getHightSize(top); int paramRight = getWidthSize(right); int paramBottom = getHightSize(bottom); ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) v.getLayoutParams(); if (left != INVALID){ params.leftMargin = paramLeft; } if (right != INVALID){ params.rightMargin = paramRight; } if (top != INVALID){ params.topMargin = paramTop; } if (bottom != INVALID){ params.bottomMargin = paramBottom; } v.setLayoutParams(params);} 更多相关文章
