Android数据库到listview clicklistener

Question

单击连接到数据库的列表视图时尝试获取名称。 搜索了解决方案，但找不到这样的解决方案。试图自己解决很长时间但没有做到。我的代码：

public void v() {
            Cursor cursor = myDBHandler.getDatabaseCursor();

            final String []arr = new String[]{myDBHandler.getColumnName()};
            int idView[]=new int[]{R.id.lv_tv2};

            SimpleCursorAdapter simpleCursorAdapter = new SimpleCursorAdapter(getBaseContext(), R.layout.lvlayout,
                    cursor, arr, idView);

            ListView lv=(ListView)findViewById(R.id.ap_Lv1);
            lv.setAdapter(simpleCursorAdapter);

            lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    Cursor cursor1 = myDBHandler.getDatabaseCursor();

                        String s = cursor1.getString(cursor1.getColumnIndex(myDBHandler.getColumnName()));

                        Toast.makeText(getApplicationContext(), s, Toast.LENGTH_LONG).show();
                    cursor1.close();
                }
            });
        }

MyDBHandler类中的

getColumnName（）方法是：

public String getColumnName(){
        return COLUMN_NAME;
    }

Answer 1

mCursor.moveToPosition(position);

String s = mCursor.getString(mCursor.getColumnIndex(myDBHandler.getColumnName()));

Toast.makeText(getApplicationContext(), s, Toast.LENGTH_LONG).show();
