我在自定义textview类上获得了膨胀异常，该类正在正确地处理其他项目，但在新项目中有膨胀异常。

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();
}
这是我的布局文件

答案 0 :(得分：0)
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。
