您好我在我的应用中使用affolestads material dialogs，但最近我注意到了一些事情。积极的button点击事件有时表现得很好但有时它只是没有启动我的{{ 1}}第一次，所以我必须再次点击它。
查看我的代码，并可能会突出显示我的错误：
AsyncTask我是通过@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_remove, menu);
//menu hiding and invalidation
this.invalidateOptionsMenu();
MenuItem item = menu.findItem(R.id.delete);
MenuItem item1 = menu.findItem(R.id.pay);
if (mFruitList.size() > 0) {
item.setVisible(true);
item1.setVisible(true);
}
if (mSpicesList.size() > 0) {
item.setVisible(true);
item1.setVisible(true);
}
if (mVeggyList.size() > 0) {
item.setVisible(true);
item1.setVisible(true);
}
if (mCerealsList.size() > 0) {
item.setVisible(true);
item1.setVisible(true);
}
return true;
}
//delete selected items
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {

} else {
Toast.makeText(getBaseContext(), "Please connect to a working network and retry", Toast.LENGTH_LONG).show();
}
}
}).show();
}
点击来调用它，然后执行了两个menu item。在AsyncTasks启动时，另一个在dialog按钮的点击事件中
答案 0 :(得分：1)
让ShowDialog()不接收标题..制作标题全局变量...如果不行......将计算放在ShowDialog()内......可能会导致延迟。< / p>
