弹出popwindow

private void initListView() {
		listView = new ListView(this);
		listView.setBackgroundResource(R.drawable.listview_background); //设置listView 背景
		listView.setDivider(null);	//设置条目之间的分隔线为null
		listView.setVerticalScrollBarEnabled(false); // 关闭
		
		listView.setAdapter(new MyListAdapter());
	}

downArrow.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				
				System.out.println("=======");
				//定义 popupWindow
				popWin = new PopupWindow(MainActivity.this);
				popWin.setWidth(input.getWidth()); //设置宽度
				popWin.setHeight(200);	//设置popWin 高度
				
				popWin.setContentView(listView); //为popWindow填充内容
				popWin.setOutsideTouchable(true); // 点击popWin 以处的区域，自动关闭 popWin
				
				popWin.showAsDropDown(input, 0, 0);//设置 弹出窗口，显示的位置
				
			}
		});

进度提示框

public void showProgressBar(String message) {
if (progressDialog != null && progressDialog.isShowing()) {
return;
}
// progressDialog.setMessage(message);
progressDialog.setCancelable(true);
progressDialog.setCanceledOnTouchOutside(true);// 点击进度条以外的部分也锁屏
progressDialog.show();
LayoutInflater inflater = LayoutInflater.from(context);
View v = inflater.inflate(R.layout.pg, null);
Window window = progressDialog.getWindow();
WindowManager.LayoutParams lp = window.getAttributes();
// 设置透明度为0.3
lp.alpha = 1.0f;
lp.dimAmount = 0.0f;
lp.gravity = Gravity.CENTER;
window.setAttributes(lp);
window.setContentView(v);
progressDialog.setOnKeyListener(MyKeyListener);
}
