OnClick使我的应用程序崩溃

我在对话框中有一个文本视图，我希望在单击该文本视图时执行某些操作
当我点击文本视图做某事时，我想要它。

我在布局中添加了可点击和点击
这是我的代码

public class Activitytwo extends ActionBarActivity {
    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        //WORKING CODES
        //WORKING CODES
        //WORKING CODES
        //WORKING CODES
    }
    // This one to show the dialog
    //This one works fine!
    public void share(View view){
        sharedialog = new Dialog(Activitytwo.this);
        sharedialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        sharedialog.setContentView(R.layout.postdialog);
        sharedialog.setCanceledOnTouchOutside(true);
        sharedialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
        sharedialog.show();
        }
    public void facebookp(View view){
        //This one for the TextView (onClick)
        //This one doesn't work..
    }
}

这是我的布局（postdialog.xml）
