我有一个从数据库填充的自定义列表视图,我希望当点击textview的任何项目值传递给另一个活动时,我该怎么办? 请帮帮我!
这是所有代码,谢谢你 源代码: 修改:
public class ListActivity extends Activity {
String value = "";
MovieDB myDbHelper;
SQLiteDatabase db;
ListAdapter adapter;
ArrayList<HashMap<String, String>> data;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_layout);
final ListView lst=(ListView) findViewById(R.id.listView1);
Load_Database();
db = myDbHelper.getReadableDatabase();
Cursor c = db.rawQuery("select * from movie_list where product = '"+value+"' Or name like '%"+value+"%'" , null);
data = new ArrayList<HashMap<String, String>>();
for (; c.moveToNext();) {
HashMap<String, String> map = new HashMap<String, String>();
String img = c.getString(c.getColumnIndex("img"));
String name = c.getString(c.getColumnIndex("name"));
map.put("img", img);
map.put("name", name);
data.add(map);
}
adapter = new ListMovie(this, data);
lst.setAdapter(adapter);
lst.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
final Intent GoToDisplay = new Intent(ListActivity.this,DisplayActivity.class);
GoToDisplay.putExtra("position", data.get(arg2));
startActivity(GoToDisplay);
}
});
}
private void Load_Database() throws Error {
myDbHelper = new MovieDB(ListActivity.this);
try {
myDbHelper.createDataBase();
} catch (IOException ioe) {
throw new Error("Unable to create database");
}
try {
myDbHelper.openDataBase();
} catch (SQLException sqle) {
throw sqle;
}
}
}

第1步:
只需使用ListView中的位置从适配器获取数据。
有关。 e.g。
You have ArrayList<String> data;//
然后访问,像
GoToDisplay.putExtra("position", data.get(arg2)); // as arg2 referees to clicked item position from ListView
第2步:
从视图中获取点击TextView
TextView clickedTextView = (TextView)arg1.findViewById(// Id of your TextView); // Or get child from view arg1
GoToDisplay.putExtra("position", clickedTextView.getText().toString());
注意:由于我们不知道你的适配器数据,上面的代码只是理解的例子。
