我的fonttextview类代码

{package com.sgtaxi.driver.widgets;
import android.content.Context;
import android.content.res.TypedArray;
import android.text.TextUtils;
import android.util.AttributeSet;
import android.widget.TextView;
import com.westchester.ride.driver.R;
import com.sgtaxi.driver.utils.FontUtils;
import com.sgtaxi.driver.utils.Fonts;


public class FontTextView extends TextView {

public FontTextView(Context context) {
    super(context);
}

public FontTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    applyAttributes(context, attrs);
}

public FontTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    applyAttributes(context, attrs);
}

private void applyAttributes(Context context, AttributeSet attrs) {
    TypedArray a = context.obtainStyledAttributes(attrs,
            R.styleable.FontTextView);
    String fontName = Fonts.values()   [a.getInt(R.styleable.FontTextView_fontName, 0)].getName();
    a.recycle();
    if (!isInEditMode() && !TextUtils.isEmpty(fontName)) {
        setTypeface(FontUtils.getFonts(getContext(), fontName));
    }
 }
}

My Activity Oncreate方法，其中我使用setContentView 

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.acitivity_login);

    initializeViews();
    setlistners();

}

有一个类关联错误android studio没有识别我的小部件。 我只是删除我的

  

com.sgtaxi.driver.widgets.FontTextView

在xml中再次输入以建立关联..并且它有效。
