I created a Dialog with single-choice list items:
final CharSequence[] items = {"Red", "Green", "Blue"};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Colors");
builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
}
});
AlertDialog alert = builder.create();
alert.show();
How can I customize the layout of this dialog so that each list item in the dialog consists of a icon and a text. How to create custom layout for the list on the dialog?
Steps for Creating customize dialog:
Create the dialog box layout files, like:
<RelativeLayout xmlns:android = "http://schemas.android.com/apk/res/android"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content">
<!-- The Title Bar -->
<LinearLayout
android:id="@+id/dlg_priority_titlebar"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
<ImageView
android:src="@drawable/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dip" />
<TextView
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:text = "Select Task Priority"
android:layout_gravity = "center_vertical" />
</LinearLayout>
<ListView
android:id="@+id/dlg_priority_lvw"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/dlg_priority_titlebar"
android:background="@drawable/layout_home_bg">
</ListView>
Because the layout in the ListView
custom, so to create a layout file for the ListView
:
<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android"
android:orientation = "horizontal"
android:layout_width = "fill_parent"
android:layout_height = "fill_parent">
<ImageView
android:id = "@+id/list_priority_img"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:layout_gravity = "center_vertical"
android:layout_margin = "5dip" />
<TextView
android:id = "@+id/list_priority_value"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:layout_gravity = "center_vertical"
android:textsize = "28dip"
android:textColor = "@drawable/ black" />
</LinearLayout>
Create a custom Dialog
class PriorityDlg
inherited from Dialog
public class PriorityDlg extends Dialog {
private Context context;
private ListView dlg_priority_lvw = null;
public PriorityDlg(Context context) {
super(context);
this.context = context;
// TODO Auto-generated constructor stub
}
public PriorityDlg(Context context, int theme) {
super(context, theme);
this.context = context;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.setContentView(R.layout.dlg_priority);
dlg_priority_lvw = (ListView) findViewById(R.id.dlg_priority_lvw);
// ListView
SimpleAdapter adapter = new SimpleAdapter(context, getPriorityList(),
R.layout.lvw_priority, new String[] { "list_priority_img",
"list_priority_value" }, new int[] {
R.id.list_priority_img, R.id.list_priority_value });
dlg_priority_lvw.setAdapter(adapter);
//ListView
dlg_priority_lvw
.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
}
});
}
private List<HashMap<String, Object>> getPriorityList() {
List<HashMap<String, Object>> priorityList = new ArrayList<HashMap<String, Object>>();
HashMap<String, Object> map1 = new HashMap<String, Object>();
map1.put("list_priority_img", R.drawable.priority_not_important);
map1.put("list_priority_value", context.getResources().getString(
R.string.dlg_priority_not_important));
priorityList.add(map1);
HashMap<String, Object> map2 = new HashMap<String, Object>();
map2.put("list_priority_img", R.drawable.priority_general);
map2.put("list_priority_value", context.getResources().getString(
R.string.dlg_priority_general));
priorityList.add(map2);
HashMap<String, Object> map3 = new HashMap<String, Object>();
map3.put("list_priority_img", R.drawable.priority_important);
map3.put("list_priority_value", context.getResources().getString(
R.string.dlg_priority_important));
priorityList.add(map3);
HashMap<String, Object> map4 = new HashMap<String, Object>();
map4.put("list_priority_img", R.drawable.priority_very_important);
map4.put("list_priority_value", context.getResources().getString(
R.string.dlg_priority_very_important));
priorityList.add(map4);
return priorityList;
}
}
To create a custom dialog box
PriorityDlg dlg = new PriorityDlg (SimpleTaskActivity.this, R.style.dlg_priority);
dlg.show();
Where R.style.dlg_priority
set the dialog box uses the style file, just let the dialog box to remove the title bar, and of course you can code to complete this effect:
<? Xml version = "1.0" encoding = "utf-8"?>
<resources>
<style name="dlg_priority" parent="@android:Theme.Dialog">
<item name = "android: windowNoTitle"> true </ item>
</ style>
</ resources>
