pass edittext value using array

Question

I have more than 3 edittext. When i enter something inside edittext i need to save this to another screen. I referred some question got answer. But how to pass through array. I used separate putExtra method of each edittext and another screen i need to display one TextView. Now i created separate TextView for each.

code:

Activity:

 et=(EditText)findViewById(R.id.et);

            et1=(EditText)findViewById(R.id.et1);

            btn=(Button)findViewById(R.id.btn);

            btn.setOnClickListener(new OnClickListener(){

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub

                    Intent intent = new Intent(Save.this, Get.class);
                String[] myStrings = new String[] {"et.getText().toString()", "et1.getText().toString()"};
                intent.putExtra("strings", myStrings);
                startActivity(intent);


SharedPreferences preferences = getDefaultSharedPreferences(this);
                  SharedPreferences.Editor editor = preferences.edit();
                  editor.putString("Name","test");
                  editor.commit();

                    }


            });

Activity1:

    Intent intent = getIntent();
              String[] myStrings = intent.getStringArrayExtra("strings");

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
          String name = preferences.getString("Name","");


              txt=(TextView)findViewById(R.id.txt);
                txt.setText(myStrings);

setText gives error: The method setText(CharSequence) in the type TextView is not applicable for the arguments (String[]) — user2674668

myStrings is an array, so you have to access the values as myStrings[0], myStrings[1] and so on. — Enrichman

I've written an answer, so you can see an example. If you need further help just ask. :) — Enrichman

I'll write a complete answer.

Intent intent = new Intent(Save.this, Get.class);
String[] myStrings = new String[] { et.getText().toString() ,  et1.getText().toString() };
intent.putExtra("strings", myStrings);
startActivity(intent);

and then

Intent intent = getIntent();
String[] myStrings = intent.getStringArrayExtra("strings");

txt1=(TextView)findViewById(R.id.txt1);
txt1.setText(myStrings[0]);

txt2=(TextView)findViewById(R.id.txt2);
txt2.setText(myStrings[1]);

or you can just join the strings and pass it to a single TextView

Intent intent = getIntent();
String[] myStrings = intent.getStringArrayExtra("strings");

String joined = myStrings[0] + " - " + myStrings[1];

txt=(TextView)findViewById(R.id.txt);
txt.setText(joined);

Hope this will help.

Usually I write a class that will handle the SharedPrenferences with some static method, like:

public class Storage {

    public static String getName(Context context) {
        final SharedPreferences prefs = context.getSharedPreferences("com.my.package", Context.MODE_PRIVATE);
        return prefs.getString("name", "");
    }

    public static void setName(Context context, String name) {
        final SharedPreferences prefs = context.getSharedPreferences("it.enrichman.bolloauto", Context.MODE_PRIVATE);
        prefs.edit().putString("name", name).commit();
    }

}

You can try this storing it the first time in your first activity and then retrive it in the second one. Use a Toast to test.

TextView displays only et.getText().toString(), et1.getText().toString() those text not displaying what im writing

Enrichman Over a year ago

You can use just a single TextView. Edited. :)

See my code. You have wrapped et1.getText().toString() beetween double quotes, like "et1.getText().toString()". You don't have to!

Enrichman Over a year ago

You can save this data in the SharedPreferences.

This code is working properly.

    scrollview=(ScrollView)findViewById(R.id.scrollview1); 
    tb2.setTextSize(30); 
    tb2.setMovementMethod(new ScrollingMovementMethod());
    scrollview.post(new Runnable() { 
    public void run() { 
        scrollview.fullScroll(View.FOCUS_DOWN);  
        }
    }); 
    chat1.setOnClickListener(new OnClickListener() { 
        public void onClick(View v) { 
         {
             textsaring1=edt1.getText().toString();
             tb2.setText(tb2.getText()+" "+textsaring1);
             edt1.setText(" ");
        } 
        }
    }); 
}
