Android获取屏幕分辨率的三种方法

一、在activity中

1、DisplayMetrics dm = getResources().getDisplayMetrics();

int screenWidth = dm.widthPixels;

int screenHeight = dm.heightPixels;

2、DisplayMetrics dm = new DisplayMetrics();

this.getWindowManager().getDefaultDisplay().getMetrics(dm);

int screenWidth = dm.widthPixels;

int screenHeight = dm.heightPixels;

二、在service中

DisplayMetrics dm = new DisplayMetrics();

dm = getResources().getDisplayMetrics();

int screenWidth = dm.widthPixels;

int screenHeight = dm.heightPixels;

三、在非activity中，传一个Context进来调用

1、public ImageGalleryAdapter(Context c) {

myContext = c;

DisplayMetrics dm = c.getResources().getDisplayMetrics();
int screenWidth = dm.widthPixels;

int screenHeight = dm.heightPixels;

}

2、public class BaseTools {

public static int getWindowWidth(Context context){

// 获取屏幕分辨率

WindowManager wm = (WindowManager) (context.getSystemService(Context.WINDOW_SERVICE));

DisplayMetrics dm = new DisplayMetrics();

wm.getDefaultDisplay().getMetrics(dm);

int mScreenWidth = dm.widthPixels;

return mScreenWidth;

}

public static int getWindowHeigh(Context context){

// 获取屏幕分辨率

WindowManager wm = (WindowManager) (context.getSystemService(Context.WINDOW_SERVICE));

DisplayMetrics dm = new DisplayMetrics();

wm.getDefaultDisplay().getMetrics(dm);

int mScreenHeigh = dm.heightPixels;

return mScreenHeigh;

}

}
