How to use and style new AlertDialog from appCompat 22.1 and above
If you want to use the new android.support.v7.app.AlertDialog and have different colors for the buttons and also have a custom layout then have a look at my https://gist.github.com/JoachimR/6bfbc175d5c8116d411e
@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.custom_layout, null);
initDialogUi(v);
final AlertDialog d = new AlertDialog.Builder(activity, R.style.AppCompatAlertDialogStyle)
.setTitle(getString(R.string.some_dialog_title))
.setCancelable(true)
.setPositiveButton(activity.getString(R.string.some_dialog_title_btn_positive),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
doSomething();
dismiss();
}
})
.setNegativeButton(activity.getString(R.string.some_dialog_title_btn_negative),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dismiss();
}
})
.setView(v)
.create();
// change color of positive button
d.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
Button b = d.getButton(DialogInterface.BUTTON_POSITIVE);
b.setTextColor(getResources().getColor(R.color.colorPrimary));
}
});
return d;
}
When creating the AlertDialog
you can set a theme to use.
Example - Creating the Dialog
AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);
builder.setTitle("AppCompatDialog");
builder.setMessage("Lorem ipsum dolor...");
builder.setPositiveButton("OK", null);
builder.setNegativeButton("Cancel", null);
builder.show();
styles.xml - Custom style
<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<!-- Used for the buttons -->
<item name="colorAccent">#FFC107</item>
<!-- Used for the title and text -->
<item name="android:textColorPrimary">#FFFFFF</item>
<!-- Used for the background -->
<item name="android:background">#4CAF50</item>
</style>
Result
Edit
In order to change the Appearance of the Title, you can do the following. First add a new style:
<style name="MyTitleTextStyle">
<item name="android:textColor">#FFEB3B</item>
<item name="android:textAppearance">@style/TextAppearance.AppCompat.Title</item>
</style>
afterwards simply reference this style in your MyAlertDialogStyle
:
<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
...
<item name="android:windowTitleStyle">@style/MyTitleTextStyle</item>
</style>
This way you can define a different textColor
for the message via android:textColorPrimary
and a different for the title via the style.
To use a theme for all the application, and don't use the second parameter to style your Dialog
<style name="MyTheme" parent="Base.Theme.AppCompat.Light">
<item name="alertDialogTheme">@style/dialog</item>
<item name="colorAccent">@color/accent</item>
</style>
<style name="dialog" parent="Base.Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">@color/accent</item>
</style>
On my app using a color accent in theme don't show the alertDialog's buttons with the theme colorAccent I have to add a dialog style in the theme.
Follow @reVerse answer but in my case, I already had some property in my AppTheme
like
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
...
<item name="android:textColor">#111</item>
<item name="android:textSize">13sp</item>
</style>
So my dialog will look like
I solved it by
1) Change the import from android.app.AlertDialog
to
android.support.v7.app.AlertDialog
2) I override 2 property in AppTheme
with null value
<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<!-- Used for the buttons -->
<item name="colorAccent">#FFC107</item>
<!-- Used for the title and text -->
<item name="android:textColorPrimary">#FFFFFF</item>
<!-- Used for the background -->
<item name="android:background">#4CAF50</item>
<item name="android:textColor">@null</item>
<item name="android:textSize">@null</item>
</style>
.
AlertDialog.Builder builder = new AlertDialog.Builder(mContext, R.style.MyAlertDialogStyle);
Hope it help another people
