How to access a TextView / an ImageView in a ListView-child element at X position..?
I want to access the child of a ListView at position x. The ListView has the following xml layout code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:background="@drawable/bg_grad_iled">
<ImageView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="@+id/iv_icon" />
<TextView android:id="@+id/tv_name"
android:textColor="@color/kategorieTextColor"
android:layout_height="40dp"
android:textSize="16sp"
android:layout_weight=".50"
android:layout_width="0dip"
android:padding="3px"
android:layout_marginLeft="8px"/&开发者_StackOverflow中文版gt;
<TextView android:id="@+id/tv_comment"
android:textColor="@color/kategorieTextColor"
android:layout_height="40dp"
android:textSize="16sp"
android:layout_weight=".20"
android:layout_width="0dip"
android:padding="3px"/>
<TextView android:id="@+id/tv_distance"
android:textColor="@color/kategorieTextColor"
android:layout_height="40dp"
android:textSize="16sp"
android:layout_weight=".30"
android:layout_width="0dip"
android:padding="3px"/>
</LinearLayout>
How can I access, (e.g.) the textview 'tv_name' in the 5th child of the ListView? Thats my current listener:
lv1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(context, "Clicked", 1000).show();
}
});
Perhaps the adapter I use may be important? Refer this
when you click on the list item OnItemClickListener will return the view, so that you can get access through that view ..
Eg:
if you want to get text of tv_name at position 5 simply:
public void onItemClick(AdapterView<?> arg0, View v, final int position,long arg3)
{
TextView text=(TextView)v.findViewById(R.id.tv_name);
Toast.makeText(this, text.getText(), Toast.LENGTH_LONG).show();
}
});
try it and get me the feedback
