这是我的片段布局：

    <RelativeLayout

</TableLayout>

还有一个-sw720dp和一个-sw600dp-land适用于10英寸和7英寸的景观设备。

以下是应用于该片段/活动的样式的相关部分：

<style name="IssueLabel">
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:textSize">14sp</item>
    <item name="android:textStyle">bold</item>
    <item name="android:layout_weight">1</item>
</style>

<style name="IssueValue">
    <item name="android:layout_weight">2</item>
</style>

这是相同的，它是默认（手机）版本，还有另一个版本适用于10“和7”景观设备。

这定义的是基本TextView哪个文本应该是粗体这是一个自定义视图，让我们看看它是如何定义的：

public class RobotoTextView extends CustomTypefaceTextView {
    public RobotoTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void createFont() {
        super.createFont("Roboto-Regular.ttf");
    }
}

(in another file:)

public abstract class CustomTypefaceTextView extends TextView {
    private final Context mContext;

    public CustomTypefaceTextView(final Context context, final AttributeSet attrs, final int defStyle) {
        super(context, attrs, defStyle);
        mContext = context;
        createFont();
    }

    public CustomTypefaceTextView(final Context context, final AttributeSet attrs) {
        super(context, attrs);
        mContext = context;
        createFont();
    }

    public CustomTypefaceTextView(final Context context) {
        super(context);
        mContext = context;
        createFont();
    }

    /**
     * This one must call super.createFont(String)
     */
    protected abstract void createFont();

    public void createFont(String typeface) {
        if (isInEditMode()) {
            return;
        }
        try {
            final Typeface font = Typeface.createFromAsset(mContext.getAssets(), typeface);
            setTypeface(font);
        } catch (final Exception e) {
        }
    }
}

以下是Android Studio的概述（蓝色突出显示的部分是包含的布局）：

以下是Nexus 5的结果：

Result on a Nexus 5

如您所见，（并且屏幕上的问题显示:)），前四个字段不是粗体。我没有改变代码中的任何内容，所以我不明白发生了什么。

有任何线索吗？

感谢Timothy Miko，我修复了我的CustomTypeFaceTextView#createFont(String)方法，如下所示：

public void createFont(String typeface) {
    if (isInEditMode()) {
        return;
    }
    try {
        final Typeface font = Typeface.createFromAsset(mContext.getAssets(), typeface);
        Typeface currentFont = getTypeface();
        if (currentFont != null) {
            setTypeface(font, currentFont.getStyle());
        } else {
            setTypeface(font);
        }
    } catch (final Exception e) {
    }
}

现在它按预期工作。

Answer 1

问题在于net.bicou.redmine.widget.RobotoTextView。您可以通过编程方式创建Typface，然后在`TextView上调用setTypeface()，而不是定义自己的自定义TextView。

TextView在应该显示时不显示为粗体
