I'm trying to create a custom dialog in my application to show an
about window but it ain't working. Maybe one of you knows a solution?
So I have an activity with the onCreateDialog(int id) overriden in it:
@Override
protected Dialog onCreateDialog(int id) {
Dialog dialog = null;
switch (id) {
case EPISODE_LOADING_DIALOG:
...
case EXCEPTION_DIALOG:
...
case ABOUT_DIALOG:
dialog = new Dialog(getApplicationContext());
dialog.setContentView(R.layout.aboutdialog);
dialog.setTitle("MyTitle");
break;
default:
...
}
return dialog;
}
My aboutdialog layout files looks like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
>
<TextView android:id="@+id/aboutText"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textColor="#FFF"
android:text="@string/aboutText"
/>
</LinearLayout>
This is exactly as described here:
http://developer.android.com/guide/topics/ui/dialogs.html#CustomDialog
However this my exception thrown:
