Könnte es etwas so Einfaches wie die Verwendung von setView
in der AlertDialog-Klasse sein? (Zusammen mit einigen Änderungen an der .xml). Zuerst nahm ich Informationen über setView
von here.
public void setView (View view, int viewSpacingLeft, int viewSpacingTop, int viewSpacingRight, int viewSpacingBottom)
Set the view to display in that dialog, specifying the spacing to appear around that view.
Parameters:
view The view to show in the content area of the dialog
viewSpacingLeft Extra space to appear to the left of view
viewSpacingTop Extra space to appear above view
viewSpacingRight Extra space to appear to the right of view
viewSpacingBottom Extra space to appear below view
Und hier einige der Beispielcode SDK (AlertDialogSamples.java), die setView
verwendet.
case DIALOG_TEXT_ENTRY:
// This example shows how to add a custom layout to an AlertDialog
LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.alert_dialog_text_entry, null);
return new AlertDialog.Builder(AlertDialogSamples.this)
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(R.string.alert_dialog_text_entry)
.setView(textEntryView)
.setPositiveButton(R.string.alert_dialog_ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked OK so do some stuff */
}
})
.setNegativeButton(R.string.alert_dialog_cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
/* User clicked cancel so do some stuff */
}
})
.create();
}
return null;
Und schließlich sieht einen Teil der XML-Datei, wie es Ränder um den Text (alert_dialog_text_entry.xml) hinzufügt.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/username_view"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:text="@string/alert_dialog_username"
android:gravity="left"
android:textAppearance="?android:attr/textAppearanceMedium" />
Hoffe es hilft.
Irgendwelche Fortschritte? Hast du meinen Vorschlag ausprobiert? – gary
