How can I change the color of AlertDialog title an

Question

I changed the color of an AlertDialog title using this command

alert.setTitle( Html.fromHtml("<font color='#FF7F27'>Set IP Address</font>"));

But I want to change the color of the line that appear under the title; how can I do that ?

Note: I don't want to use a custom layout

Answer 1

Divider color:

It is a hack a bit, but it works great for me and it works without any external library (at least on Android 4.4).

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.dialog)
       .setIcon(R.drawable.ic)
       .setMessage(R.string.dialog_msg);
//The tricky part
Dialog d = builder.show();
int dividerId = d.getContext().getResources().getIdentifier("android:id/titleDivider", null, null);
View divider = d.findViewById(dividerId);
divider.setBackgroundColor(getResources().getColor(R.color.my_color));

You can find more dialog's ids in alert_dialog.xml file. Eg. android:id/alertTitle for changing title color...

UPDATE: Title color

Hack for changing title color:

int textViewId = d.getContext().getResources().getIdentifier("android:id/alertTitle", null, null);
TextView tv = (TextView) d.findViewById(textViewId);
tv.setTextColor(getResources().getColor(R.color.my_color));

Answer 2

check this is useful for you...

public void setCustomTitle (View customTitleView)

you get detail from following link.

http://developer.android.com/reference/android/app/AlertDialog.Builder.html#setCustomTitle%28android.view.View%29

CustomDialog.java

Dialog alert = new Dialog(this);
    alert.requestWindowFeature(Window.FEATURE_NO_TITLE);
    alert.setContentView(R.layout.title);
    TextView msg = (TextView)alert.findViewById(R.id.textView1);
    msg.setText("Hello Friends.\nIP address : 111.111.1.111");
    alert.show();

title.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Set IP address"
    android:textColor="#ff0000"
    android:textAppearance="?android:attr/textAppearanceLarge" />

<ImageView 
    android:layout_width="fill_parent"
    android:layout_height="2dp"
    android:layout_marginTop="5dp"
    android:background="#00ff00"
    />
<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="#775500"
    android:textAppearance="?android:attr/textAppearanceLarge" />

Answer 3

In the class onCreateView, I put this:

Dialog d = getDialog();
    d.setTitle(Html.fromHtml("<font color='#EC407A'>About</font>"));
    int dividerId = d.getContext().getResources().getIdentifier("android:id/titleDivider", null, null);
    View divider = d.findViewById(dividerId);
    divider.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

colorPrimary links to our colors.xml file that stores all the colors. Also d.setTitle provides a hacky way to set the title colour.

If you are creating custom Layout for alert dialog

then you may add like this way easily to change the color

<LinearLayout
    android:id="@+id/DialogTitleBorder"
    android:layout_width="fill_parent"
    android:layout_height="1dip"
    android:layout_below="@id/mExitDialogDesc"
    android:background="#4BBAE3"            <!--change color easily -->
    >

</LinearLayout>

Answer 5

If you don't want a "library" for that, you can use this badly hack:

((ViewGroup)((ViewGroup)getDialog().getWindow().getDecorView()).getChildAt(0)) //ie LinearLayout containing all the dialog (title, titleDivider, content)
.getChildAt(1) // ie the view titleDivider
.setBackgroundColor(getResources().getColor(R.color.yourBeautifulColor));

This was tested and work on 4.x; not tested under, but if my memory is good it should work for 2.x and 3.x

Answer 6

If your using custom title layout then you can use it like alertDialog.setCustomTitle(customTitle);

For example

on UI thread used dialog like 

 LayoutInflater inflater=LayoutInflater.from(getApplicationContext());
 View customTitle=inflater.inflate(R.layout.customtitlebar, null);
 AlertDialog.Builder d=new AlertDialog.Builder(this);
 d.setCustomTitle(customTitle);
 d.setMessage("Message");
 d.setNeutralButton("OK", null);
 d.show();


customtitlebar.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="#525f67">

    <ImageView
        android:id="@+id/icon"
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/ic_launcher"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true" >
    </ImageView>

    <TextView
        android:id="@+id/customtitlebar"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:textColor="#ffffff"
        android:text="Title Name"
        android:padding="3px"
        android:textStyle="bold" 
        android:layout_toRightOf="@id/icon"
        android:layout_alignParentTop="true"
        android:gravity="center_vertical"/>

     <ImageView
        android:layout_width="match_parent"
        android:layout_height="2dp"
        android:background="#ff0000" 
        android:layout_below="@id/icon"><!-- This is line below the title -->
    </ImageView>

</RelativeLayout>
