推荐答案
如果你想改变整个对话,也许使用替代对话框库这样的材料对话框的包,你可以用这个替换目录preference
:
If you want to change the whole dialog, maybe to use a replacement dialog library like this material-dialogs package, you can use this replacement ListPreference
:
import com.afollestad.materialdialogs.MaterialDialog;
public class MaterialListPreference extends ListPreference {
private MaterialDialog.Builder mBuilder;
private Context context;
public MaterialListPreference(Context context) {
super(context);
this.context = context;
}
public MaterialListPreference(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
}
@Override
protected void showDialog(Bundle state) {
mBuilder = new MaterialDialog.Builder(context);
mBuilder.title(getTitle());
mBuilder.icon(getDialogIcon());
mBuilder.positiveText(null);
mBuilder.negativeText(getNegativeButtonText());
mBuilder.items(getEntries());
mBuilder.itemsCallback(new MaterialDialog.ListCallback() {
@Override
public void onSelection(MaterialDialog dialog, View itemView, int which, CharSequence text) {
onClick(null, DialogInterface.BUTTON_POSITIVE);
dialog.dismiss();
if (which >= 0 && getEntryValues() != null) {
String value = getEntryValues()[which].toString();
if (callChangeListener(value))
setValue(value);
}
}
});
final View contentView = onCreateDialogView();
if (contentView != null) {
onBindDialogView(contentView);
mBuilder.customView(contentView);
}
else
mBuilder.content(getDialogMessage());
mBuilder.show();
}
}
它没有做太多,只是最低限度覆盖对话框显示和选择回调部分。因人而异,如果你选择一个不同的对话框库,但没有太多的非常轻微的,他们往往是或多或少的直接替代 AlertDialog
。
