我想导入ListView，但是由于某些原因，程序不能检测出 listview 的ID。我试着
清除程序项目的缓存，重启 eclipse ，但是结果还是一样。如何检测 listview 的 ID？
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.firstlist);
testcontacts = getResources()
.getStringArray(R.array.testcontacts_array);
aa = new MessageView();
lv = (ListView) findViewById(R.id.list);
lv.setAdapter(aa);
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(),
((TextView) view).getText(), Toast.LENGTH_SHORT).show();
}
});
}
Listview xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
