获取屏幕高宽,在代码中设置控件大小的方法

 1 import android.view.Display;
 2 import android.view.WindowManager;
 3 WindowManager windowManager = getWindowManager();    
 4    Display display = windowManager.getDefaultDisplay();    
 5         if(display.getWidth()==480 && display.getHeight()== 272 ||
 6                       display.getWidth()==272 && display.getHeight()==480){
 7                mDirAdapter = new DirAdapter(this, 110, 120); 
 8         }else{
 9                mDirAdapter = new DirAdapter(this, 190, 200);
10         }

 1 //方法一
 2        int h = this.getContext().getResources().getDisplayMetrics().heightPixels;
 3        int w = this.getContext().getResources().getDisplayMetrics().widthPixels;
 4        Log.v("########h#######",String.valueOf(h));
 5       
 6       
 7  //方法二
 8         WindowManager wm = (WindowManager)this.getContext()
               .getSystemService(Context.WINDOW_SERVICE);
 9         Display display = wm.getDefaultDisplay();
10         int h1 = display.getHeight();
11         int w1 = display.getWidth();

1  private Button mbtn;
2         mbtn = (Button) findViewById(R.id.btn_test);        
3         LayoutParams lp;        
4         lp=mbtn.getLayoutParams();
5         lp.width=100;
6         lp.height=200;        
7         mbtn.setLayoutParams(lp);

1 Display display = getWindowManager().getDefaultDisplay(); // 为获取屏幕宽、高 
2 Window window = getWindow(); 
3 LayoutParams windowLayoutParams = window.getAttributes(); // 获取对话框当前的参数值 
4 windowLayoutParams.width = (int) (display.getWidth() * 0.7); // 宽度设置为屏幕的0.95 
5 windowLayoutParams.height = (int) (display.getHeight() * 0.1); // 高度设置为屏幕的0.6
6 windowLayoutParams.alpha = 0.5f;// 设置透明度
