所以这里我从适配器类调用接口方法。我想List根据用户的输入更新。我将如何实现它？
适配器类：
public class ToDoListAdaptor extends SectionRecyclerViewAdapter < SectionHeader, Action, SectionViewHolder, ChildViewHolder > {
@Override
public void onBindChildViewHolder(final ChildViewHolder holder, final int sectionPosition, final int childPosition, final Action child) {
Context mainActivityContext = Constants.getContext();
if (action_id.equals("pain")) {
if (mainActivityContext != null && mainActivityContext instanceof MainActivity) {
interfaceAdapter = ((HealthVitalsFunction) mainActivityContext);
boolean result = interfaceAdapter.openPainRecordDialog(context, dbHelper, action_id, action_cat_id, action_plan_id, action_name);
if (result)
update(sectionHeaderList, childPosition);
}
}
}
}
问题是当用户完成输入时我无法调用 update() 。
编辑：
@Override
public boolean openPainRecordDialog(final Context context, final DbHelper dbHelper, final String action_id, final String action_cat_id, final String action_plan_id, final String action_name) {
Constants.painData=false;
LayoutInflater layoutInflaterAndroid = LayoutInflater.from(context);
final View mView = layoutInflaterAndroid.inflate(R.layout.pain_record, null);
final AlertDialog dialog = new AlertDialog.Builder(context)
.setView(mView)
.setTitle("")
.setPositiveButton(android.R.string.ok, null)
.setNegativeButton(android.R.string.cancel, null)
.setCancelable(false)
.create();
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(final DialogInterface dialog) {
Button positiveButton = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_POSITIVE);
positiveButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// TODO Do something
if (dialog != null && ((AlertDialog) dialog).isShowing()) {
dialog.dismiss();
}
Constants.painData = true;
}
});
Button negativeButton = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_NEGATIVE);
negativeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// TODO Do something
if (dialog != null && ((AlertDialog) dialog).isShowing()) {
dialog.dismiss();
}
Constants.painData = false;
}
});
}
});
// show it
dialog.show();
return Constants.painData;
}
