I ve been searching for hours and I can't figure out what I'm doing wrong.
"list cannot be resolved or is not a field"
here is my search.java file:
package com.example.testxxx;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.json.JSONException;
import org.json.JSONObject;
import android.app.ListActivity;
import android.app.SearchManager;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
public class Search extends ListActivity {
private TextView mTextView;
private ListView mListView;
private String query;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search);
mTextView = (TextView) findViewById(R.id.text);
mListView = (ListView) findViewById(R.id.list);
}
}
and here is my search.xml layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".Search" >
<TextView
android:id="@+id/text"
android:textColor="?android:textColorPrimary"
android:background="@android:drawable/title_bar"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="0dp" />
</RelativeLayout>
I have noticed that if i change
android:id="@android:id/list"
to
android:id="@android:id/list"
then it will find it, but if i do so, i will have another error because I am extending listactivity that need the listview to have the ID set this way (android:id="@android:id/list")
Do you have a solution? Thank you!
Just replace
mListView = (ListView) findViewById(R.id.list);
with
mListView = (ListView) findViewById(android.R.id.list);
or simply you can call
mListView = getListView()
as you are extending ListActivity
and your xml layout contains a ListView
with id android.R.id.list
when you referencing to internal ID's (ID's may be drawable ID's, String ID's or any resource) then those ID's will not be generated in your R.java. you have to import those ID's from where you referenced.
