可点击TextView错误

Question

我尝试让TextView像这样可点击

<TextView
        android:layout_marginTop="16dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/fbtxt"
        android:text="@string/fbtext"
        android:layout_margin="16dp"
        android:textSize="@dimen/text_size"
        android:layout_gravity="center_vertical"
        android:clickable="true" />    

在。java类

中

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_about);
TextView fbtxt = (TextView) this.findViewById(R.id.fbtxt);
    fbtxt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) { 
Intent main = new Intent (getApplicationContext(), MainActivity.class);
            startActivity(main);  
        }
    });    

但是什么都没发生，请帮忙
编辑:
实际代码为:

public void onClick(View v) {  
            Intent fbclick = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com"));
            startActivity(fbclick);
        }

替换

  getApplicationContext   

与java类，从你想去MainActivity
