android获取屏幕的宽度和高度

WindowManager winManage = getWindowManager() ;
Display winDisplay = winManage.getDefaultDisplay() ;
int winHeight = winDisplay.getHeight() ;
int winWeight = winDisplay.getWidth() ;

 

 

   获取屏幕的长度和宽度，这个在Dialog中同样适用的

 

 

 // 自定义对话框

class IdentikitDialogs extends Dialog implements android.view.View.OnClickListener {
		
		private Button b1;
		private Window window = null;
		private TextView tvMsg ;
		private String msg ;
		public IdentikitDialogs(Context context, String msg) {
			super(context);
			this.msg = msg ;
		}

		public void setDisplay() {
			setContentView(R.layout.identikit_dialog);// 设置对话框的布局
			tvMsg = (TextView)this.findViewById(R.id.tv_identikit_action) ;
			tvMsg.setGravity(Gravity.CENTER) ;
			tvMsg.setText(msg) ;
			b1 = (Button) findViewById(R.id.clo);
			b1.setOnClickListener(this);
			setProperty();
			//setTitle("自定义对话框");// 设定对话框的标题
			show();// 显示对话框
		}

		// 要显示这个对话框，只要创建该类对象．然后调用该函数即可．
		public void setProperty() {
			
			WindowManager winManage = getWindowManager() ;
			Display winDisplay = winManage.getDefaultDisplay() ;
			int winHeight = winDisplay.getHeight() ;
			int winWeight = winDisplay.getWidth() ;
			
			window = getWindow();// 　　　得到对话框的窗口．
			WindowManager.LayoutParams wl = window.getAttributes();
			wl.x = 0;// 这两句设置了对话框的位置．0为中间
			wl.y = 180;
			wl.alpha = 0.6f;// 这句设置了对话框的透明度
		//	wl.gravity = Gravity.BOTTOM;
			wl.height = winHeight ;
			wl.width = winWeight ;
			wl.gravity = Gravity.TOP ;
			window.setAttributes(wl);
		}

		@Override
		public void onClick(View v) {
			dismiss();// 取消
		}
	} //end class

 

其中 setContentView(R.layout.identikit_dialog);// 设置对话框的布局 

是自己在xml文件中定义的布局
