我有一个从OnClick回调方法调用的方法。
public enum Foo {
BAR_1("Bar 1"),
BAR_2("Bar 2");
private String friendlyValue;
Foo(String friendlyValue){
this.friendlyValue = friendlyValue;
}
public String getFriendlyValue() {
return friendlyValue;
}
public static Foo fromFriendlyValue1(String friendlyValue){
return Stream.of(Foo.values()).filter(r -> r.getFriendlyValue().equals(friendlyValue)).findFirst().get();
}
public static Foo fromFriendlyValue2(String friendlyValue) {
return Arrays.stream(Foo.values()).filter(r -> r.getFriendlyValue().equals(friendlyValue)).findFirst().get();
}
}
public void onClick(View v) {
switch (v.getId()){
case R.id.irating:
ilist();
break;
方法看起来像
ilist()现在，如何在按钮的另一个OnClick方法中获取选择的arraylist，我需要将选择列表传递给另一个活动。
家长活动：
public Arraylist ilist() {
final ArrayList selectedratings = new ArrayList();
// Have alert dialog with multichoice options and
// Using Shared preference to store selected values and remind in dialog
return selectedratings;
}
儿童活动：
public class AllMovieRating extends ActionBarActivity implements View.OnClickListener {
private Views mViews;
final ArrayList ilist = new ArrayList();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_all_movie_rating);
mViews=new Views();
mViews.irating.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.imdb_rating:
ilist();
break;
}
}
private void filtervalues() {
Intent intent = new Intent(AllRating.this,sharedcollect.class);
intent.putExtra("im",ilist);
startActivity(intent);
}
public ArrayList ilist() {
final CharSequence[] ratings = {"1", "2", "3", "4", "5", "6", "7", "8", "9", "10"};
final boolean[] ratingschecked = {false, false, false, false, false, false, false, false, false, false};
SharedPreferences sharedPreferences = this.getSharedPreferences("checkedrate_i", Context.MODE_PRIVATE);
final SharedPreferences.Editor editor = sharedPreferences.edit();
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
int size = sharedPreferences.getInt("size", 0);
for(int j=0;j<size;j++)
{
ilist.add(sharedPreferences.getString("selectedratings" + j, null));
//Log.e("Kumar", "" + selectedratings);
}
for(int j=0;j<=ratingschecked.length;j++){
if(ilist.contains((String.valueOf(j)))) {
ratingschecked[j-1] = true;
}
}
builder.setTitle("Select Ratings");
builder.setMultiChoiceItems(ratings, ratingschecked, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
if (isChecked) {
if(!ilist.contains((String)String.valueOf(ratings[which]))){
ilist.add(String.valueOf(ratings[which]));
ratingschecked[which]=true;
}
} else if ((ilist.contains((String)String.valueOf(ratings[which])))) {
ilist.remove(String.valueOf(ratings[which]));
// Log.e("Kumar", String.valueOf(ratings[which]));
ratingschecked[which]=false;
}
}
}).setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// editor.putString("checked", String.valueOf(selectedratings));
for (int i = 0; i < ilist.size(); i++) {
editor.putString("selectedratings" + i, String.valueOf(ilist.get(i)));
}
editor.putInt("size", ilist.size());
editor.apply();
//Log.e("Shiva", String.valueOf(selectedratings));
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
AlertDialog dialog = builder.create();
builder.show();
return ilist;
}
