Android开发之获取屏幕相关属性

几乎每个app都会用到屏幕相关的属性,所以我在这将常用的属性封装成了工具类

首先新建一个工具类(ScreenUtils)

1.获取屏幕宽高:

public static DisplayMetrics getScreenSize(Context context){
    DisplayMetrics metrics = new DisplayMetrics();
    WindowManager wm = (WindowManager)context
        .getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();
    display.getMetrics(metrics);
    return metrics;
}

2.屏幕density(密度)

public static float getDeviceDensity(Context context){
    DisplayMetrics metrics = new DisplayMetrics();
    WindowManager wm = (WindowManager)context
        .getSystemService(Context.WINDOW_SERVICE);
    wm.getDefaultDisplay().getMetrics(metrics);
    return metrics.density;
}
