使用 RemoteView 自动调整 Widget 中的文本大小

Question

我尝试使用this example here (AutoResizeTextView) 和this example here (FontFitTextView) 来调整小部件中文本的大小。

我有一个更新小部件的BroadcastReceiver，在这个BroadcastReceiver 中我有以下内容。我构造了RemoteView：

AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(mContext);
ComponentName thisWidget = new ComponentName(mContext, Widget.class);
RemoteViews views = new RemoteViews(mContext.getPackageName(), R.layout.widget);

然后我设置变量之一：

//convert to Fahrenheit if Fahrenheit selected
views.setTextViewText(R.id.wTemperature, convertTemperature(parts[4]) + "\u00B0");

我已将我的 widget.xml 相应地调整为：

<uk.co.diong.weatherlive_ish.FontFitTextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textColor="#ffffff"
    android:textSize="29sp"
    android:textStyle="bold"
    android:gravity="center"
    android:text="Temp"
    android:id="@+id/wTemperature" />

但我的小部件现在声明 问题加载小部件，所以现在我想知道几个小时后，这是否适用于 RemoteViews？这两个类都扩展了 TextView 而不是 RemoteView。

Answer 1

您无法在RemoteView 中加载自定义视图。

Android Doc 说，Widget 中只能加载少数 Layouts 和 Views。恐怕无法调整大小。

Answer 2

我不知道下面的答案是否正确，但请尝试一下

问题可能是由 com.android.support:appcompat-v7:21.0.3 引起的，这是使用 Android 的新布局功能所需的主要依赖项。尝试回到 v7:20.0.0，这应该可以解决问题。
