android获取屏幕宽高,imageview动态设置宽高

android获取屏幕的高度和宽度用到WindowManager这个类，两种方法： 

 

1、WindowManager wm = (WindowManager) getContext()

                    .getSystemService(Context.WINDOW_SERVICE);

 

     int width = wm.getDefaultDisplay().getWidth();

     int height = wm.getDefaultDisplay().getHeight();

 

2、WindowManager wm = this.getWindowManager();

 

     int width = wm.getDefaultDisplay().getWidth();

     int height = wm.getDefaultDisplay().getHeight();

 

// 动态设置imageview的宽高

1. image = (ImageView)findViewById(R.id.ImageView01);  
2.         //height = image.getHeight();  
3.         //width = image.getWidth();  
4.         //Log.d(TAG, "height: " + height);  
5.         //Log.d(TAG, "width: " + width);  
6.           
7.           
8.         LayoutParams para;  
9.         para = image.getLayoutParams();  
10.           
11.         para.height = 300;  
12.         para.width = 300;  
13.         image.setLayoutParams(para);
