Cannot set text to EditText from custom dialog

Question

I had some problem with setting text to EditText. There are no error occur and I can get text from customDialog, but when I set text to edittext nothing happen.

This is a pact of xml file that use to set up edittext.

<LinearLayout
            android:id="@+id/setting_layout_fname"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="horizontal"
            android:weightSum="100"
            android:clickable="true">

            <TextView
                android:layout_height="wrap_content"
                android:layout_weight="25"
                android:clickable="false"
                android:text="Firstname"
                android:textStyle="bold"
                android:layout_width="wrap_content" />


            <android.support.design.widget.TextInputLayout
                android:id="@+id/setting_textLayout_fname"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:layout_gravity="right"
                android:layout_weight="75"
                android:clickable="false">

                <android.support.design.widget.TextInputEditText
                    android:id="@+id/setting_edittext_fname"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:clickable="false"/>
            </android.support.design.widget.TextInputLayout>

        </LinearLayout>

And this is code to handle my alertdialog.

    toolbar.setCollapsible(true);
    setSupportActionBar(toolbar);
    getSupportActionBar().setTitle("Setting");
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);

    input_fname = (TextInputEditText) findViewById(R.id.setting_edittext_fname);
    input_fname.setText("test");

    layout_list.add(linear_max = (LinearLayout) findViewById(R.id.setting_textLayout_maxglucose));*/

    for(LinearLayout linearLayout : layout_list){
        linearLayout.setOnClickListener(this);
    }
}

public void onClick(View v){
    if(v.getId() == R.id.setting_layout_fname){
        final EditText edittext = new EditText(getApplicationContext());
        alertdialog.setTitle("First Name");
        alertdialog.setMessage("Enter your firstname: ");
        alertdialog.setView(edittext);
        alertdialog.setPositiveButton("Yes", new DialogInterface.OnClickListener(){
            public void onClick(DialogInterface dialog, int whichButton) {
                final String fname = edittext.getText().toString();
                Toast.makeText(setting.this, fname, Toast.LENGTH_SHORT).show();
                setting.this.input_fname.setText( fname,  TextView.BufferType.EDITABLE);
            }
        });
        alertdialog.setNegativeButton("No", new DialogInterface.OnClickListener(){
            public void onClick(DialogInterface dialog, int whichButton) {
            }
        });
        alertdialog.create().show();
    }
}

don't know what happen with my code, Toast always show same value as I put it but it not show in edittext of mainActivity.

Answer 1

code have 2 edittext, the 1st is editText in alertdialog that created programmatically, and the 2nd is editText that create in xml file.

All I want to do is setText to editText in xml with value from editText in alertdialog. I can got the value from edittext in alertdialog but cannot setText to editText in xml file.

private TextInputEditText input_fname;
private List<LinearLayout> layout_list;
private AlertDialog.Builder alertdialog;

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_setting);

    toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.activity_setting_toolbar);
    toolbar.setCollapsible(true);
    setSupportActionBar(toolbar);
    getSupportActionBar().setTitle("Setting");
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);

    input_fname = (TextInputEditText) findViewById(R.id.setting_edittext_fname);
    input_fname.setText("test");
    layout_list.add(linear_fname = (LinearLayout) findViewById(R.id.setting_layout_fname));

    for(LinearLayout linearLayout : layout_list){
        linearLayout.setOnClickListener(this);
    }
}

public void onClick(View v){
    if(v.getId() == R.id.setting_layout_fname){
        final EditText edittext = new EditText(getApplicationContext());
        alertdialog.setTitle("First Name");
        alertdialog.setMessage("Enter your firstname: ");
        alertdialog.setView(edittext);
        alertdialog.setPositiveButton("Yes", new DialogInterface.OnClickListener(){

                Toast.makeText(setting.this, fname, Toast.LENGTH_SHORT).show();
                setting.this.input_fname.setText( fname,  TextView.BufferType.EDITABLE);
            }
        });
        alertdialog.setNegativeButton("No", new DialogInterface.OnClickListener(){
            public void onClick(DialogInterface dialog, int whichButton) {
            }
        });
        alertdialog.create().show();

    }
}

Answer 2

Hmmm... I figure something. When I create new xml class withly slight same element with the old one, It perfectly work either with editText or textView. So I think I did some mistake and overlook it. So I guess that I should answer my own question.
