Try this way,hope this will help you to solve your problem.

activity_main.xml

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:gravity="center"android:orientation="vertical"><TextViewandroid:id="@+id/textview"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="TextView"/><Spinnerandroid:id="@+id/spinner"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="10dp"/></LinearLayout>

strings.xml

<arrayname="colorname"><item>Red</item><item>Yellow</item><item>Green</item><item>Blue</item><item>Pink</item></array><arrayname="colorcode"><item>#FF0000</item><item>#ffff00</item><item>#00ff00</item><item>#0000ff</item><item>#FF0080</item></array>

MainActivity.java

publicclassMainActivityextendsActivity {

    privateSpinner spinner;
    privateTextView textview;
    privateArrayList<String> colorNameList;
    privateArrayList<String> colorCodeList;

    @OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textview = (TextView) findViewById(R.id.textview);
        spinner = (Spinner) findViewById(R.id.spinner);

        colorNameList = newArrayList<String>(Arrays.asList(getResources().getStringArray(R.array.colorname)));
        colorCodeList = newArrayList<String>(Arrays.asList(getResources().getStringArray(R.array.colorcode)));

        final ArrayAdapter<String> dataAdapter = newArrayAdapter<String>(this,
                android.R.layout.simple_spinner_item, colorNameList);
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(dataAdapter);

        spinner.setOnItemSelectedListener(newAdapterView.OnItemSelectedListener() {
            @OverridepublicvoidonItemSelected(AdapterView<?> parent, View view, int position, long id) {
                textview.setTextColor(Color.parseColor(colorCodeList.get(position)));
            }

            @OverridepublicvoidonNothingSelected(AdapterView<?> parent) {

            }
        });
    }
}

Solution 2:

YourSpinner.setOnItemSelectedListener(newOnItemSelectedListener() {
        @OverridepublicvoidonItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id)
        {
           YourTextView.setTextColor(getResources().getColor(R.color.some_color));
            // your code here

        }

        @OverridepublicvoidonNothingSelected(AdapterView<?> parentView) {
            // your code here
        }

    });

It would be nice if you've tried searching on Stack Site.

Solution 3:

publicclassMainActivityextendsActionBarActivity {

private TextView text;
private Spinner spin;
ArrayList al;

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
text=(TextView)findViewById(R.id.textView1);
spin=(Spinner)findViewById(R.id.spinner1);
al=newArrayList();
al.add("RED");
al.add("BLUE");
ArrayAdapter adapter=newArrayAdapter<>(getApplicationContext(), android.R.layout.simple_list_item_activated_1,al);
spin.setAdapter(adapter);
spin.setOnItemSelectedListener(newOnItemSelectedListener() {

    @OverridepublicvoidonItemSelected(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) {
        // TODO Auto-generated method stubswitch(arg2)
        {
        case0:
            text.setText("srikanth");
            text.setTextColor(Color.RED);
            break;
        case1:
            text.setText("SRIkANTH BLUE");
            text.setTextColor(Color.BLUE);
            break;

        }

    }

    @OverridepublicvoidonNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

    }
});


}

}

I hope it helps you
