如何在Android中失去连接后停止进度条旋转

Question

当我按下手机上的返回按钮后，我关闭了 wifi 或移动数据网络。

进度条旋转没有停止，后退按钮不起作用。

    protected void onRefreshingStateChanged(boolean refreshing) {
    super.onRefreshingStateChanged(refreshing);

    if (!refreshing){
        if (mProgressDialog != null && isBackPressed){
            mProgressDialog.hide();
            mProgressDialog = null;
            this.setResult(RESULT_OK, getIntent());
            finish();
        }

    }else{
        if (mProgressDialog == null && isBackPressed){
            mProgressDialog = ProgressDialog.show(this, "Fetching Data",
                    "Please wait while we are updating records ...", true);
        }
    }
}

尝试设置进度条的cancelable属性。

mProgressDialog = new ProgressDialog(this);
mProgressDialog.setCancelable(true);
