android获取屏幕的分辨率方法

获取屏幕分辨率的方式如下：

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;
}
}
