Unable to add window token null is not for an application 

  AlertDialog.Builder localBuilder = new AlertDialog.Builder(Service_Activity.this);
// 这里使用getApplicationContext() 报错 必须使用当前activity。

1.这里的type初始值为null，则在第一次点击是toast的值是*null，然后选择tsg，那么下一次toast值才是tsg，总是得不到本次选择的值.?

在没有完成alertdialog选择时，程序就往下跑去了…… 吧操作写在alert里面吧，感觉又不大好……

 imageView1.setOnClickListener(new View.OnClickListener() {

                final String[] arrayOfString = { "ATPCU", "C2CU", "SDP", "TSG", "COMC","BTM" };
                localBuilder.setTitle("选择模块").setIcon(R.mipmap.ic_launcher).setItems(arrayOfString, new DialogInterface.OnClickListener()
                {
                    public void onClick(DialogInterface paramAnonymousDialogInterface, int paramAnonymousInt)
                    {
                        //  Toast.makeText(MainActivity.this, "你选择了： " + arrayOfString[paramAnonymousInt], Toast.LENGTH_SHORT).show();

                        type=arrayOfString[paramAnonymousInt];
                    }
