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);}@Overridepublic 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
