Accessing Another Activity's Textview For Appending Text In Different Activities

First of all thanks for reading and spending your time for solving this problem. I have some Acivities which each contain a button for going to next. The last One contains a TextVi

Solution 1:

Use SharedPreferences as shown here to save your appended string after each activity and just use that in the last one as textview.setText(pref.getString("key",null));

If you dont understand how to create/use SharedPreferences leave a comment and ill be happy to help

Update: in every activity declare-

SharedPreferences pref;
SharedPreferences.Editor editor;

then inside onCreate()-

pref = getSharedPreferences("name", MODE_PRIVATE);editor = pref.edit();

you can use any string instead of "name" above. Its the name of your SharedPreference file.

now to save string -

editor.putString("myString", "some string");
editor.apply();

to get string -

String s=pref.getString("MyString",null);

Just getString in 2nd activity onwards ->append using '+' -> save it again using editor.put. That should do it :) google SharedPreferences for further info

Solution 2:

You can put your text in intents which you use to start your activity.

Intenti=newIntent(FirstScreen.this, SecondScreen.class);   
StringstrName="abc";
i.putExtra("STRING_I_NEED", strName);

Then in the next activity you can get the text by

Bundleextras= getIntent().getExtras();
if(extras == null) {
    newString= null;
} else {
    newString= extras.getString("STRING_I_NEED");
}

Solution 3:

You can use intent.putExtra() method like

   Intent intent = newIntent(this, your_next_activity.class);
   intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
   intent.putExtra("src", textViewResult.getText().toString() );
   startActivity(intent);

then in you next activity in oncreate() method use below to retrieve

Intenti= getIntent();
    Strings= i.getExtras().getString("src");

Solution 4:

In your case, the easiest way is: using Application:

//create class App that extends android.app.ApplicationpublicclassAppextendsApplication {
     publicStringyourTextToShow="";    

     @OverridepublicvoidonCreate() {
         super.onCreate();
    }
}

Modify your AndroidManifest.xml 's <application> tag to have the attribute android:name="your.package.name.App".

From then on, whenever you want to change/access your text to from any Activity, just call: ((App)getApplication()).yourTextToShow = "textyouwant";. In your case, you need to reset your TextView in onResume of your activity.

P/s: dont try to use static TextView. It's the worst practice. It will create memory leaks to your app.
