Activity.xml中TextView的代码

<TextView
    android:id="@+id/textview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

package com.example.android_day001;

import java.util.Random;

import android.os.Bundle; import android.app.Activity; import
android.graphics.Color; import android.view.Menu; import
android.view.View; import android.view.View.OnClickListener; import
android.widget.TextView;

public class MainActivity extends Activity {

    @Override   protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);         TextView textview;
        textview = (TextView) this.findViewById(R.id.textview);

        textview.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                Random random = new Random(255);
                textview.setTextColor(Color.rgb(random.nextInt(),
                        random.nextInt(), random.nextInt()));           }       });     }

List item

    @Override   public boolean onCreateOptiosMenu(Menu menu) {      //
Inflate the menu; this adds items to the action bar if it is
present.        getMenuInflater().inflate(R.menu.main, menu);       return
true;   }

}

编辑器在代码的textview.setTextColor();处报错
