public static ProgressDialog initDialog(Context context) {
		ProgressDialog progressDialog = new ProgressDialog(context);
		progressDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
		progressDialog.setCanceledOnTouchOutside(false);
		progressDialog.setMessage("loading...");
		//使其按下Back键无用
		progressDialog.setCancelable(false);
		//使其点击对话框以外的地方不起作用
		progressDialog.setCanceledOnTouchOutside(false);

		progressDialog.setOnKeyListener(new OnKeyListener() {
			@Override
			public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
				if (keyCode==KeyEvent.KEYCODE_SEARCH) {
