我的ListView显示来自数据库的数据,我想要的是当我点击特定的ListView选项时,新的活动开始,并且在该活动中,显示与所选选项相关的数据。
我在打开新活动时没有问题,但我无法让该活动知道ListView上选择了哪个选项。
ListView代码:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
database = new projectdatabase(ProjectExplorer.this);
openDatabase();
}
private void openDatabase() {
database.open();
cursor = database.getDataforDisplay();
adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_1, cursor, new String[] {"project_name"}, new int[] { android.R.id.text1 }, 0);
setListAdapter(adapter);
}
@Override
public void onListItemClick(ListView parent, View view, int position, long id) {
super.onListItemClick(parent, view, position, id);
Intent intent = new intent(this, openactivity.class);
startActivity(intent);
//What else to add here?
}
我只想将“project_name”发送到其他活动,以便我查询并检索其他信息。

在列表项目上获取project_name
,然后单击为:
@Override
public void onListItemClick(ListView parent, View view, int position, long id) {
super.onListItemClick(parent, view, position, id);
Cursor c = ((SimpleCursorAdapter)parent.getAdapter()).getCursor();
c.moveToPosition(position);
// get project name here
String str_projectname= c.getString(c.getColumnIndex("project_name"));
Intent intent = new intent(this, openactivity.class);
intent.putExtra("project_name", str_projectname);
startActivity(intent);
//What else to add here?
}
