代码中打开页面代码：

private void openHomeView(){
    	final AlertDialog dialog = new AlertDialog.Builder(LeitingActivityUtils.getActivity()).create();
    	dialog.show();
    	final Window window = dialog.getWindow();
    	window.setContentView(R.layout.home);
    	// 获取宽高
    	WindowManager wm = window.getWindowManager();
    	final int height = wm.getDefaultDisplay().getHeight();
    	final int width = wm.getDefaultDisplay().getWidth();
    	LayoutParams lp = window.getAttributes();
    	// 设置窗体的宽高
    	lp.height = (int)(height * 0.7);
    	lp.width  = (int)(width * 0.7);
    	window.setAttributes(lp);
    	
    	ImageView forgetPwd = (ImageView) window.findViewById(R.id.forget_pwd);
    	ImageView register = (ImageView) window.findViewById(R.id.regiser);
    	ImageView registeredLogin = (ImageView) window.findViewById(R.id.registered_login);
    	ImageView visitor = (ImageView) window.findViewById(R.id.visitor);
    	
    	// 已有账号登录
    	registeredLogin.setOnClickListener(new View.OnClickListener() {
    		@Override
    		public void onClick(View v) {
    			// 打开已有账号登录界面
    			window.setContentView(R.layout.login);
    		}
    	});
    }
