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() {
@Override
public void onClick(View v) {

public void onClick(DialogInterface paramAnonymousDialogInterface, int paramAnonymousInt)

// Toast.makeText(MainActivity.this, “你选择了： ” + arrayOfString[paramAnonymousInt], Toast.LENGTH_SHORT).show();
type=arrayOfString[paramAnonymousInt];
