How To Customize The Color Of The Checkmark Color In Android In A Dialog. : Android

How to customize the color of the CheckMark color in android in a dialog. Currently , By default, the color of the checkmark is green by default. I would like to customize it to a

Solution 1:

If you look at the styles.xml from android system, you will see that the checkbox style is defined as follows :

<stylename="Widget.CompoundButton.CheckBox"><itemname="android:background">@android:drawable/btn_check_label_background</item><itemname="android:button">@android:drawable/btn_check</item></style>

And If you search the resources of the system, you will see that btn_check is a drawable selector with 2 states (on/off) with the check colored green or not. So if you want to have your own color-drawable, here is what you should do : - create a styles.xml - define the 2 drawables to use - create the xml file supporting the selector

You can find the full documentation quite detailled on the android google doc.

Solution 2:

To change the checkbox inside a multi-choice dialog, you need a custom adapter for your dialog, so as to have access to the views of the list. Then, you call method setCheckMarkDrawable of class CheckedTextView.

Here is an example:

File default_checkbox.xml inside res/drawable

<?xml version="1.0" encoding="utf-8"?><selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:state_checked="true"android:drawable="@drawable/checkbox_checked" /><!-- checked --><itemandroid:state_pressed="true"android:drawable="@drawable/checkbox_checked" /><!-- pressed --><itemandroid:drawable="@drawable/checkbox_default" /><!-- default --></selector>

File DialogUtil.java

package example.dialog;

import android.app.AlertDialog;
import android.content.Context;
import android.util.Log;
import android.view.*;
import android.widget.*;
import android.widget.AdapterView.OnItemClickListener;

publicclassDialogUtil {

    privateDialogUtil() {
    }

    publicstatic AlertDialog show(Context context) {
        String[] items = {"text 1", "text 2", "text 3"};
        AlertDialog.Builderbuilder=newAlertDialog.Builder(context);
        builder.setTitle("Test")
            .setPositiveButton("OK", null)
            .setAdapter(newCustomAdapter(context, items), null);
        AlertDialogdialog= builder.show();

        ListViewlist= dialog.getListView();
        list.setItemsCanFocus(false);
        list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
        list.setOnItemClickListener(listener);
        return dialog;
    }

    privatestaticOnItemClickListenerlistener=newOnItemClickListener() {

        @OverridepublicvoidonItemClick(AdapterView<?> parent, View view, int position, long id) {
            Log.i("DialogUtil", "Clicked on " + view);
        }
    };

    privatestaticclassCustomAdapterextendsArrayAdapter<String> {

        publicCustomAdapter(Context context, String[] array) {
            super(context, android.R.layout.simple_list_item_multiple_choice, array);
        }

        @Overridepublic View getView(int position, View convertView, ViewGroup parent) {
            Viewview=super.getView(position, convertView, parent);
            if (view instanceof CheckedTextView) {
                CheckedTextViewcheckedView= (CheckedTextView) view;
                checkedView.setCheckMarkDrawable(R.drawable.default_checkbox);
            }
            return view;
        }
    }
}

NOTE: If you simply use AlertDialog, then before getting the ListView, you call show, firstly, like explained above.

However, if you use DialogFragment and onCreateDialog, then you get the ListView, inside onStart.

You have to override checkbox widget styles with modified drawable resources. Here is good guide to start with styles/themes http://brainflush.wordpress.com/2009/03/15/understanding-android-themes-and-styles/
