我正在开发一个简单的Android应用程序。我想在单击列表项时使用另一个活动显示listview属性。但我突然犯了错误。

这是我的java类，

import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.TextView;

// Main class for creating job_id lists
public class TourNumberList extends ListActivity{

TourNumberListAdapter tourNumberListAdapter;

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tour_list);


TourInfoDatabaseHelper jobInfoDatabaseHelper = new TourInfoDatabaseHelper(this);

Cursor cursorTourNumberInfo = jobInfoDatabaseHelper.getAllJobInfoRecords();

    if(cursorTourNumberInfo.moveToFirst()){
        do{
            String jobId = cursorTourNumberInfo.getString(0);
            String startLocation = cursorTourNumberInfo.getString(1);
            String endLocation = cursorTourNumberInfo.getString(2);
            String type = cursorTourNumberInfo.getString(3);
            String tourNumber = cursorTourNumberInfo.getString(5);

            android.util.Log.d("DB value", jobId+" "+startLocation+" "+endLocation+" "+type+" "+tourNumber);
        }while(cursorTourNumberInfo.moveToNext());
    }



    ListView listView = (ListView) findViewById(R.id.tourList);
    tourNumberListAdapter = new TourNumberListAdapter(this, cursorTourNumberInfo);
    listView.setAdapter(tourNumberListAdapter);

     // Get listview
    ListView lv = getListView();

    // on seleting single product
    // launching Edit Product Screen
    lv.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            // getting values from selected ListItem
            String startLocation = ((TextView) view.findViewById(R.id.start_location_invisible)).getText().toString();
            String endLocation = ((TextView) view.findViewById(R.id.end_location_invisible)).getText().toString();
            String type = ((TextView) view.findViewById(R.id.type_invisible)).getText().toString();
            String tourNumber = ((TextView) view.findViewById(R.id.tour_number_invisible)).getText().toString();

            // Starting new intent
            Intent in = new Intent(getApplicationContext(),
                    TourInfo.class);
            // sending pid to next activity
            in.putExtra("startLocation", startLocation);
            in.putExtra("endLocation", endLocation);
            in.putExtra("type", type);
            in.putExtra("tourNumber", tourNumber);

            // starting new activity and expecting some response back
            startActivity(in);
        }


    });


}

}

我正在使用CursorAdapter for listView，

public class TourNumberListAdapter extends CursorAdapter{

public TourNumberListAdapter(Context context, Cursor cursor) {
    super(context, cursor);
}

@Override
public void bindView(View view, Context context, Cursor cursor) {

    TextView tourNumTextView = (TextView) view.findViewById(R.id.job_id);
    tourNumTextView.setText(cursor.getString(0));
    TextView startLocationInvisibleTextView = (TextView) view.findViewById(R.id.start_location_invisible);
    startLocationInvisibleTextView.setText(cursor.getString(1));
    TextView endLocationInvisibleTextView = (TextView) view.findViewById(R.id.end_location_invisible);
    endLocationInvisibleTextView.setText(cursor.getString(2));
    TextView typeInvisibleTextView = (TextView) view.findViewById(R.id.type_invisible);
    typeInvisibleTextView.setText(cursor.getString(3));
    TextView tourNumberInvisibleTextView = (TextView) view.findViewById(R.id.tour_number_invisible);
    tourNumberInvisibleTextView.setText(cursor.getString(4));

}

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
    View view = layoutInflater.inflate(R.layout.tour_list_item,parent,false);
    return view;
}

}

这是我的listView的.xml文件，

<?xml version="1.0" encoding="UTF-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tourList"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

</ListView>

这是我的Logcat错误，

请帮我解决此错误。

2 个答案:

答案 0 :(得分：3)

试试这个..

您使用ListActivity然后在布局中ListView的ID应为@android:id/list 

<?xml version="1.0" encoding="UTF-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

</ListView>

并删除ListView listView = (ListView) findViewById(R.id.tourList);然后

 // Get listview
ListView lv = getListView();
tourNumberListAdapter = new TourNumberListAdapter(this, cursorTourNumberInfo);
setListAdapter(tourNumberListAdapter);

lv.setOnItemClickListener(new OnItemClickListener() {

答案 1 :(得分：0)

将您的listview的ID更改为@android:id/list

所以使用这个

<?xml version="1.0" encoding="UTF-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>

而不是

<?xml version="1.0" encoding="UTF-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tourList"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

</ListView>
