Se pourrait-il que ce soit quelque chose d'aussi simple que d'utiliser setView
dans la classe AlertDialog? (Avec quelques modifications au fichier .xml). Tout d'abord, j'ai pris des informations sur setView
de 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
Et voici quelques exemples de code de SDK (AlertDialogSamples.java) qui utilise setView
.
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;
Et enfin, une partie du fichier xml ressemble il ajoute des marges autour du texte (alert_dialog_text_entry.xml).
<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" />
Espérons que cela aide.
Progression en cours? Avez-vous essayé ma suggestion? – gary
