Android获取窗体信息的Util方法

android获取窗体信息的util方法，方法很简单，这里就不多废话了，直接上代码

package com.wangyi.tools;

import android.app.activity;
import android.util.displaymetrics;

public class displayutils {
  
  private static displayutils instance;
  private activity mactivity;
  private displayutils(activity mactivity){
    this.mactivity=mactivity;
  }
  public static displayutils getinstance(activity mactivity){
    if(instance==null){
      instance=new displayutils(mactivity);
    }
    return instance;
  }
  public final int[] getscreensize(){
    int[] size=new int[2];
    displaymetrics dm = new displaymetrics();
    mactivity.getwindowmanager().getdefaultdisplay().getmetrics(dm);
    size[0]=dm.widthpixels;
    size[1]=dm.heightpixels;
    return size;
  }
  public final static int getwindowwidth(activity mactivity) {
    displaymetrics dm = new displaymetrics();
    mactivity.getwindowmanager().getdefaultdisplay().getmetrics(dm);
    return dm.widthpixels;
  }

  public final static int getwindowheight(activity mactivity) {
    displaymetrics dm = new displaymetrics();
    mactivity.getwindowmanager().getdefaultdisplay().getmetrics(dm);
    return dm.heightpixels;
  }
}
