Android 连接丢失后如何停止进度条旋转

Question

当我按下手机上的后退按钮时 phone 然后我关闭了 wifi 或移动数据网络。

进度条旋转不停止，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);
        }
    }
}

Answer 1

尝试设置进度条cancelable属性。

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