Android ListView selected item stay highlighted

android, android-listview, java

Solution

To hold the color of listview item when you press it, include the following line in your listview item layout:

android:background="@drawable/bg_key"

Then define `bg_key.xml` in `drawable` folder like this:

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_selected="true"
        android:drawable="@color/pressed_color"/>
    <item
        android:drawable="@color/default_color" />
</selector>

Finally, include this in your `ListView` `onClickListener`:

listView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,long arg3) {
        view.setSelected(true);
        ... // Anything
    }
});

This way, only one item will be color-selected at any time. You can define your color values in `res/values/colors.xml` with something like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="pressed_color">#4d90fe</color>
    <color name="default_color">#ffffff</color>
</resources>

Problem

I have an `XML` with two `ListView`, one with a list of clients filled by a select query (`lv_cli`) and the other with the details of the client selected (`lv_cli_det`). I would like to keep the client selected in the `lv_cli` while the `lv_cli_det` show the details. XML: ``` <ListView android:id="@+id/cli_lista" android:layout_width="512dp" android:layout_height="wrap_content" android:fadeScrollbars="false" > </ListView> <ListView android:id="@+id/cli_lista_det" android:layout_width="512dp" android:layout_height="wrap_content" android:layout_toRightOf="@+id/cli_lista" android:fadeScrollbars="false" > </ListView> ``` Java: ``` Cursor cursor = db.rawQuery("Select NrCl||';'||Nome From Clientes", null); final ListView t = (ListView)findViewById(R.id.cli_lista); ArrayAdapter<String> myarrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, listItems); t.setAdapter(myarrayAdapter); final ListView td = (ListView)findViewById(R.id.cli_lista_detalhe); final ArrayAdapter<String> myarrayAdapter2 = new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, listItems2); t.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { String item = ((TextView)view).getText().toString(); String[] strArray = item.split("\\;"); cli.load(strArray[0].toString()); td.setAdapter(myarrayAdapter2); listItems2.clear(); listItems2.add("Nome: " + cli.getNome()); listItems2.add("Morada: " + cli.getMorada()); listItems2.add("Localidade: " + cli.getLoca()); listItems2.add("Código Postal: " + cli.getCp()); listItems2.add("Pais: " + cli.getPais()); listItems2.add("Nif: " + cli.getNif()); listItems2.add("Tel: " + cli.getTel()); listItems2.add("Tlm: " + cli.getTlm()); listItems2.add("Tipo Preço: " + cli.getTipoPvn()); listItems2.add("Cond. Pagamento: " + cli.getCpg()); listItems2.add("Obs: " + cli.getObs()); td.setAdapter(myarrayAdapter2); myarrayAdapter2.notifyDataSetChanged(); } }); ```
