我使用自定义适配器来实现listview而不是默认的简单列表视图。现在,我想为其添加Firebase功能,以使用它的实时数据库功能。
我知道实施默认FirebaseAdapter方法的步骤,但如何使用Firebase为listview实现自定义适配器?
简单FirebaseAdapter的代码:
mRef = new Firebase("https://<myURL>..");
com.firebase.ui.FirebaseListAdapter<String> myAdapter;
myAdapter = new FirebaseListAdapter<String>(this,String.class,android.R.layout.simple_list_item_1,mRef) {
@Override
protected void populateView(View view, String s, int i) {
TextView text = (TextView) view.findViewById(android.R.id.text1);
text.setText(s);
}
};
final ListView lv = (ListView) findViewById(R.id.listView);
lv.setAdapter(myAdapter);
答案 0 :(得分:0)
可以这样做:
public class MainActivity extends AppCompatActivity {
Firebase mRef;
com.firebase.ui.FirebaseListAdapter<String> myAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mRef = new Firebase("https://<myURL>..");
myAdapter = new FirebaseListAdapter<String>(this,String.class,android.R.layout.simple_list_item_1,mRef) {
@Override
protected void populateView(View view, String s, int i) {
TextView text = (TextView) view.findViewById(android.R.id.text1);
text.setText(s);
}
};
final ListView lv = (ListView) findViewById(R.id.listView);
lv.setAdapter(myAdapter);
}
}
