出错：

java.lang.IllegalArgumentException

View=DecorView@f875f83[] not attached to window manager

解决：

@Override
public void onPause() {//加个取消
    super.onPause();
    if ((null != progressDialog) && progressDialog.isShowing()) {
        progressDialog.dismiss();
    }
    progressDialog = null;
}

if (!isDestroy(getActivity())) { //加个判断
    if (progressDialog == null) {
        progressDialog = new Dialog(context, R.style.progress_dialog);
    }

    if (progressDialog.isShowing()) {
        progressDialog.dismiss();
    }
    progressDialog.setContentView(R.layout.logindialog);
    progressDialog.setCancelable(true);
    progressDialog.setCanceledOnTouchOutside(false);
    Window window = progressDialog.getWindow();
    if (window != null) {
        window.setBackgroundDrawableResource(android.R.color.transparent);
    }
    progressDialog.show();
}

if (progressDialog != null) {
    if (progressDialog.isShowing()) {
        progressDialog.dismiss();
    }
    progressDialog = null;
}

//判断Activity是否Destroy
protected boolean isDestroy(Activity activity) {
    return activity == null || activity.isFinishing() ||
            (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1 && activity.isDestroyed());
}
