Get event on dialog( Ok ,Cancel) button pressed(Android)

Question

In my Android application I am displaying the dialogbox which contains edittext. This dialogbox is displayed using PreferenceCategory.My xml file looks like

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >

    <PreferenceCategory android:title="@string/security_setting_edittext_hint" >
        <EditTextPreference
        android:dialogTitle="@string/security_setting_button"
        android:key="set_password_preference"
        android:summary="@string/set_password_summary"
        android:title="@string/security_setting_button"
        android:inputType="number"
        android:icon="@drawable/lock"
         />
    </PreferenceCategory>

</PreferenceScreen>

My Java file looks like

public class Settings extends PreferenceActivity {

    Dialog setPasswordDialog;
    EditText setPassword;
    EditTextPreference editPreference;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setTitle("Settings");
        addPreferencesFromResource(R.xml.preference_authentication);
        editPreference=(EditTextPreference)   findPreference("set_password_preference");

}

There is no issue in displaying the dialog but now i want tho get event when Ok and Cancel button from dialog box is pressed to do something. Please provide me solution.

As you want to use the dialogbox displayed using PreferenceCategory, you will need to create a custom EditTextPreference as shown in the answer by @appsroxcom. – Sharpshooter

Answer 1

If I get your question correctly, you want to handle the "Ok" and "Cancel" event and then perform some action based on the response.

// This is using code:
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("TITLE HERE");
alert.setMessage("MESSAGE");

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
     //Do something here where "ok" clicked
    }
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
    //So sth here when "cancel" clicked.
    }
});
alert.show();

Thanks for response. If my understanding about this answer is correct then I don't want to create new dialog box.I want to use the dialogbox displayed using PreferenceCategory – Flickinger

You will need to create your custom edit text preference as follows.

public class MyEditTextPreference extends EditTextPreference {

    public MyEditTextPreference(Context context) {
        super(context);
    }
    public MyEditTextPreference(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
    public MyEditTextPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch (which) {
        case DialogInterface.BUTTON_POSITIVE:
        // Put your logic here for Ok button press
        break;

        case DialogInterface.BUTTON_NEGATIVE:
        // Put your logic here for Cancel button press
        break;      
        }
        super.onClick(dialog, which);
    }
}

Then use it in xml file as follows:

<com.package.MyEditTextPreference
android:dialogTitle="@string/security_setting_button"
android:key="set_password_preference"
android:summary="@string/set_password_summary"
android:title="@string/security_setting_button"
android:inputType="number"
android:icon="@drawable/lock"
 />

where com.package should be replaced by the actual package in your project where you create MyEditTextPreference
