Question

I have 2 views in my app. A form input and a screen to review the form data and confirm. The user inputs the data on the form submission screen in edittext fields. When the user clicks submit, they are presented with the data they input and a ‘back’ and ‘confirm’ button. I want it so that if the user presses back, they are returned to the form input screen and the data they input should still be in the editText fields.

At the moment, I am using an onClickListener to point to the form submission screen but the forms are all blank. How do I keep the data in them?

This is the onClickListener:

bBack.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Intent j = new Intent(FormConfirm.this, FormCreate.class);
            startActivity(j);
        }
    });

As stated you should save the values somehow, for example by using SharedPreferences.

As an example, when you go from the Input-form Activity to the Submit-form Activity:

bSubmit.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Intent j = new Intent(FormCreate.this, FormSubmit.class);
        saveInput();
        startActivity(j);
    }
});

Where the method saveInput() could look something like:

private void saveInput() {
    EditText input = (EditText) findViewById(R.id.someId);
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
    preferences.edit().putString("input",input.getText().toString()).commit();   
}

And then, when you press back, the back action could simply be something like:

bBack.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        FormConfirm.this.finish();
    }
});

That will cause the current activity to exit and your previous activity will be visible. If you want to display the last saved input when the Input-form Activity starts, you can simply do something like this:

private void loadInput(){
    EditText input = (EditText) findViewById(R.id.someId);
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
    String savedText = getString("input", "default input text");
    input.setText(savedText);   
}

and call that method in the onCreate-method in your Input-form Activity.
