I'm making an Android app, but I don't know how to take out any items from any location from my customized ListView.
item.xml
<TextView
android: id="@+id/id_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="25sp"/>
<TextView
android:id="@+id/name_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/relationship_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/date_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android: id="@+id/place_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
activity_main.xml
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:drawSelectorOnTop="false"
android:layout_weight="1">
</ListView>
Part of MainActivity
@Override
protected void onResume() {
super.onResume();
setContentView(R.layout.activity_main);
SQLiteDatabase db=helper.getReadableDatabase();
ListView listView1=(ListView) findViewById (R.id.listView);
// Get DB
cursor=db.query("persons", null, null, null, null, null);
cursor.moveToFirst();
listView1.setAdapter(newSimpleCursorAdapter(this,R.layout.item,cursor,newString[]{
"_id", "name", "relationship", "date", "place"}, new int [ ] {R.id.id_item, R.id.name_item, R.id.relationship, R.id.date_item, R.id.place_item}, 0);
listView1.setOnItemClickListener(newAdapterView.OnItemClickListener(){
public void onItemClick(AdapterView<?>parent, View view, int position, longid) {
}
});
}
When ListView is clicked, I would like to take out the contents of R.id.id_item and substitute the variables, but I don't know how to take out the contents of TextView in any position.What should I do?
Up until now, I have moved to the position with cursor.moveToPosition(position), but I'm having trouble finding that I can't use it when I rearrange ListView.
Use cursor.getColumnIndex("name") to extract items from Cursor:
String currentId=cursor.getString(cursor.getColumnIndex("_id"));
String currentName=cursor.getString(cursor.getColumnIndex("name"));
For example:
listView1.setOnItemClickListener(newAdapterView.OnItemClickListener(){
public void onItemClick(AdapterView<?>parent, View view, int position, longid) {
String currentId = cursor.getString( cursor.getColumnIndex("_id"));
String currentName=cursor.getString(cursor.getColumnIndex("name"));
Log.v(TAG, "Click id/name is:"+currentId+"=>"+currentName);
}
});
If it is good to get it from TextView of the clicked item,
The view argument of onItemClick() has been passed a view of the item, so
TextView textView=(TextView) view.findViewById(R.id.id_item);
String text=(String)textView.getText();
How about
