Hi, I recently stumbled upon a weird error saying NullPointerException on updateTextSize. Any suggestion or insight why this happen?

Hi,

I am wondering how can i create a icon with circular background?

what am i trying to do:

IconicFontDrawable iconicFontDrawable = new IconicFontDrawable(this.getApplicationContext()); iconicFontDrawable.setIcon("fa-thumbs-up"); iconicFontDrawable.setIconColor(getResources().getColor(R.color.light_blue));

//setBackground will fulfill the whole view with icon

i saw issue #19 however setBackgroundColor is not present anymore.

Can somebody help me?

Thanks

Instead of having to import the source code and add the project as a gradle subproject, it would be easier if you put droidicon on jCenter so one could simply do

repositories {
    jcenter()
}

dependencies {
    compile 'com.thedazzler.droidicon:droidicon:1.0'
}

If you need any help, feel free to ask.

So that others can import this project from IDE, and make them to contribute to this project easier. Without those files, the current version cannot be imported from any IDE directly from a fresh check out.

    IconicFontDrawable icon = new IconicFontDrawable(context);
    icon.setIcon("fa-trash");
    icon.setIconColor(context.getResources().getColor(R.color.white));
    deleteImg.setImageDrawable(icon);

This will draw nothing on the ImageView... I noticed that your "how-to" was using "setBackground" instead but I cannot seem to use setImageDrawable, because setBackground seems to scale the image with the parent container.

Any tips?

When using a custom icon (tried several icon sets) on Android Lollipop, the icon itself is very small (and stays that way despite changing it's size via droidicon:db_size. The circle resizes appropriately however.

Tried the same code on a device running Android 4.4.4 on which it works as expected.

Code used:

<com.thedazzler.droidicon.badges.DroidiconBadge
        android:layout_centerHorizontal="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        droidicon:db_bg_color="@color/blue_800"
        droidicon:db_icon_color="@color/white"
        droidicon:db_icon="gmd-person"
        droidicon:db_size="130dp"
        />

Hi, awesome work :) Wondering can this work with drawables ? like:

background="@drawable/fa-home"

And add customized attrs like 'inverted' to drawable ?

Just like the CSS counterparts.

I used the instagram badge but there's just a blue circle and the instagram icon was too tiny. Hope you can fix this. Other badges works well. Thank you!

I have the following:

           <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="horizontal"
                android:padding="@dimen/spacing_large"
                android:background="@color/red"
                >
                <com.thedazzler.droidicon.badges.DroidiconBadge
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center_vertical"
                    android:background="@color/orange"
                    app:db_icon_color="@color/white"
                    app:db_icon="gmd-warning"
                    app:db_icon_padding="1dp"
                    android:foregroundGravity="center_vertical"
                    />
                <TextView
                    android:layout_weight="1"
                    android:layout_width="0dp"
                    android:layout_height="wrap_content"
                    android:text="Warning!."
                    android:textColor="@color/white"
                    />
          </LinearLayout>

When I add the db_icon_padding="1dp", the icon isn't displayed. If I remove it, the icon is shown as expected.

So I did a test with a pre built icon and a custom icon. The premade icon show correctly but the custom icon just shows a green circle with an android in it. Even I specified the icon the in the xml like so? Please help?

<LinearLayout xmlns:droidicon="http://schemas.android.com/apk/res-auto" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <com.thedazzler.droidicon.badges.AndroidDroidiconBadge android:layout_width="wrap_content" android:layout_height="wrap_content" droidicon:db_bg_color="@color/black" droidicon:db_icon_color="@color/white" droidicon:db_icon="fa-user" /> <com.thedazzler.droidicon.badges.VimeoDroidiconBadge android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="4dp" /> </LinearLayout>

Is it possible to add a setIcon(String) method to DroidconBadge? Something like

 public void setIcon(String icon){

    iconicFontDrawable = new IconicFontDrawable(getContext());
    iconicFontDrawable.setIcon(icon);
    iconicFontDrawable.setIconColor(iconColor);
    iconicFontDrawable.setIconPadding((int) icon_padding);
    iconicFontDrawable.setContourColor(contourColor);
    iconicFontDrawable.setContour(contourColor, contourWidth);
    iconicFontDrawable.drawContour(drawContour);
    iconicFontDrawable.setAlpha(alpha);


    if (SDK_INT < JELLY_BEAN) {
        view_icon.setBackgroundDrawable(iconicFontDrawable);
    } else {
        view_icon.setBackground(iconicFontDrawable);
    }
}

This would be very useful in adapters where xml inflating is not available.

I realise this library is probably discontinued now, but if anyone has any tips on how to get the icons to center in the middle of the circles for Android 24+, I'd be very grateful. To recreate this, just create a new project that supports 24 and runs on a device with 24, the custom icon will appear in the bottom left.

Thanks

I'm using Android Studio 1.2 RC. I've just added the lib (version 0.1.9) to build.gradle and I get the following error:

Error:(23, 9) Attribute application@icon value=(@mipmap/ic_launcher) from AndroidManifest.xml:23:9
Error:(23, 9) Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute application@icon value=(@mipmap/ic_launcher) from AndroidManifest.xml:23:9
    is also present at com.github.theDazzler:droidicon:0.1.9:13:9 value=(@drawable/ic_launcher)
    Suggestion: add 'tools:replace="android:icon"' to <application> element at AndroidManifest.xml:20:5 to override

At the Manifest, on line 23, inside the application tag, I have android:icon="@mipmap/ic_launcher". The project was created with Android Studio 1.2, which uses mipmap for icons and other drawables - you have a folder res/drawables and then folders res/mipmap-hdpi, res/mipmap-xhdpi etcetera.

I've added the tools:replace="android:icon"inside the applicationtag and the error disappears.

Hi,

I have a clean project created in Android Studio with DroidIcon added via Gradle. Using the example layout shown below the icon appears perfectly on a Nexus 5 running Lollipop, and a Nexus 5 on OS 21 .. but on a Galaxy S1 (yes, 1 :-p) running OS 18, no icon is shown, just the circular background .. the same happens on a Nexus 7. I don't think it's an OS issue, I get the feeling it's more to do with screen density or something because if I go to this method

private void updateTextSize(Rect viewBounds)

.. and edit out the second setTextSize, which is after the delta is applied, the icons appear on all devices .. far too big and cut off, but they do appear, so the missing icon might not be to do with the icon not displaying at all, just that it displays too small after the delta is applied?

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:droidicon="http://schemas.android.com/apk/res-auto"
    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=".MainActivity$PlaceholderFragment">

    <com.thedazzler.droidicon.badges.DroidiconBadge
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        droidicon:db_bg_color="@android:color/black"
        droidicon:db_icon_color="@android:color/white"
        droidicon:db_icon="fa-user"
        />

</RelativeLayout>

Any ideas on how to fix this? I'm happy to give it a go myself if you point me in the right direction!

Thanks,

Steven
