我已经设置了一个 ListView 和一个 SimpleAdapter，它们通过在 AsyncTask 中运行的函数获取数据，但问题是我现在想在这个 ListView 上设置一个 setOnItemClickListener。
问题是我正在尝试附加一个 setOnItemClickListener 但这是在我的 AsyncTask 在 onLoad 中完成之前附加的，这意味着没有绑定(bind)。
所以我的问题是如何让 Async 执行并完成填充我的 ListView 并绑定(bind) setOnItemClickListener 我的 Async 任务完成了吗？
注意:我已经用类和 View 的完整代码更新了我的答案，因为这是由用户提出的，并且会给其他人更多的见解。如需完整代码，请向下滚动到更新部分!
代码:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contact_overview);
//Context inladen
context = ContactOverview.this;
listViewContacts = (ListView)findViewById(R.id.listViewContacts);
//new GetAllContactsAsync().execute();
asny.execute();
Log.i("finished?","finished?");
Log.i("listLength", "" + listViewContacts.getCount());
listViewContacts.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view, int position, long id) {
Toast.makeText(ContactOverview.this, "ee", Toast.LENGTH_SHORT).show();
Log.i("test","test");
}
});
}
listViewContacts.setOnItemClickListener 应在 Async 任务完成后附加。那么我应该怎么做呢？如果我的 listViewContacts.setOnItemClickListener 在我的 Async 任务完成之前被触发，则不会进行绑定(bind)..

最佳答案
将这个属性放入每个TextView
android:focusable="false"
android:focusableInTouchMode="false"
