I am developing a small app for android. I use a ListView with a TextView and a CheckBox.
I can already handle the CkeckBox tick. Furthermore I want to make the whole row of the ListView clickable, but I cannot find any ways to realise this.
I already tried to make the ListView clickable with:
android:clickable="true"
And I also tried it with this code for the ListView:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(null,"Clicked",Toast.LENGTH_LONG
}
});
Here is my code for the ListView:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context="de.matthias.lolchampionowner.app.ChampionActivity">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/championListView"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true" />
</RelativeLayout>
Like whatsapp did it. With Android Studio I could find out that this is also a ListView but the code it too obfuscated to get anything out of it.
Here is a picture: WhatsApp ListView
I have no idea how to realise it. I appeciate any help.
Here is the answer from nKn:
U have to Override the getView method. Here is my code and I can handle both clicks from the ListView and the CheckBox diveded:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView == null) {
convertView = inflater.inflate(R.layout.row_name_check, null);
holder = new ViewHolder();
holder.textView = (TextView) convertView.findViewById(R.id.textViewRow);
holder.checkBox = (CheckBox) convertView.findViewById(R.id.checkBoxRow);
convertView.setTag(holder);
}
holder = (ViewHolder) convertView.getTag();
final ChampionActivity.EachRow row = this.getItem(position);
row.checked = ItemStorage.getChampSkinOwned(row.text);
holder.textView.setText(row.text);
holder.checkBox.setChecked(row.checked);
holder.checkBox.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(((CheckBox)v).isChecked()) {
ItemStorage.setChampSkinOwned(row.text, true);
} else {
ItemStorage.setChampSkinOwned(row.text, false);
}
}
});
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d("onClick", row.text + " clicked");
//Toast.makeText(null,"Clicked",Toast.LENGTH_LONG);
}
});
return convertView;
}
Probably the best idea is extending an ArrayAdapter
and override the getView()
method. The second parameter of this method is a View
(usually called convertView
, but not necessarily), vaguely speaking, is the representation of a row, so this method will be called for each row. Simply declare your onClickListener()
over it.
@Override
public View getView(final int position, View convertView, final ViewGroup parent) {
...
convertView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View v) {
...
}
});
...
}
