Question

我的Android Studio版本1.2.1.1有问题。正如标题中所提到的，我对API 21/22的预览并没有保持正确的视图大小，但是在手机上，视图看起来就像应该看起来一样。有办法解决这个问题吗？

我有扩展类TextView，因此它支持自定义字体：

public class FontTextView extends TextView{
public FontTextView(Context context){
    super(context);
}

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

public FontTextView(Context context, AttributeSet attrs, int defStyleAttr){
    super(context, attrs, defStyleAttr);
    readAttributes(context, attrs);
}

private void readAttributes(Context context, AttributeSet attrs){
    TypedArray attributes = context.obtainStyledAttributes(attrs, R.styleable.FontTextView);
    int fontIndex = attributes.getInt(R.styleable.FontTextView_customFont, 0);

    this.setTypeface(TypefaceCreator.getTypeface(fontIndex));
    attributes.recycle();
}
}

我有一个在应用程序启动时构建这些字体的类：

public class TypefaceCreator {

public static final int HELVETICA_MEDIUM = 0;
public static final int HELVETICA_LIGHT = 1;
public static final int HELVETICA_ITALIC = 2;
public static final int HELVETICA_ROMAN = 3;

private static Typeface light;
private static Typeface italic;
private static Typeface roman;
private static Typeface medium;

private static TypefaceCreator creator;

private TypefaceCreator(Context context){
    light = Typeface.createFromAsset(context.getAssets(),"HelveticaNeueLTPro-Lt.otf");
    italic = Typeface.createFromAsset(context.getAssets(),"HelveticaNeueLTPro-It.otf");
    roman = Typeface.createFromAsset(context.getAssets(),"HelveticaNeueLTPro-Roman.otf");
    medium = Typeface.createFromAsset(context.getAssets(),"HelveticaNeueLTPro-Md.otf");
}

public static TypefaceCreator getInstance(Context context){
    if(creator == null)
        creator = new TypefaceCreator(context);
    return creator;
}

public static Typeface getTypeface(int index){
    switch(index) {
        case HELVETICA_LIGHT:
            return light;
        case HELVETICA_ITALIC:
            return italic;
        case HELVETICA_ROMAN:
            return  roman;
        default:
            return medium;
    }

}
}
