how to get two dimensional string Array from one Activity to other [closed]

Answer 1

You can use Android Parcelable Class for passing Serializable data like Arrays. Below is the Example in your case.

public class MyParcelable implements Parcelable{

    public String[][] strings;

    public String[][] getStrings() {
        return strings;
    }

    public void setStrings(String[][] strings) {
        this.strings = strings;
    }

    public MyParcelable() {
        strings = new String[1][1];
    }

    public MyParcelable(Parcel in) {
        strings = (String[][]) in.readSerializable();
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeSerializable(strings);

    }
    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {

        @Override
        public MyParcelable createFromParcel(Parcel in) {
            return new MyParcelable(in);
        }

        @Override
        public MyParcelable[] newArray(int size) {
            return new MyParcelable[size];
        }
    };
}

To pass to Another Activity -

public String[][] strings = new String[1][1];
strings[0][0] = "data";

MyParcelable myParcelable = new MyParcelable();
myParcelable.setStrings(strings);
intent.putExtra("parcel",myParcelable);
startActivity(intent);

To Retrieve -

Intent intent = getIntent();
Bundle b = intent.getExtras();
MyParcelable myParcelable = b.getParcelable("parcel");
strings = myParcelable.getStrings();
Log.d("Your String[0][0] is - ",strings[0][0]+"");

Output -

12-29 12:49:39.016: D/Your String[0][0] is -(1484): data
