How do I change TextView font style in a Home screen widget?

Question

如何在主屏幕小部件中的TextView中更改字体样式？

Answer 1

If you mean in runtime, a simple way is:

Text Size

yourRemoteView.setFloat(R.id.textview, "setTextSize", 30);

Text Color

yourRemoteView.setInt(R.id.textview, "setTextColor", Color.RED);

Answer 2

Like this:

First, define text styles in values/styles.xml :

<resources>
    <style name="AppTheme" parent="android:style/Theme.Light">
        ....
    </style>
    <style name="WidgetEntryTitle" parent="style/AppTheme">
        <item name="android:textSize">24sp</item>
        <item name="android:textStyle">bold</item>
        <item name="android:textColor">@android:color/black</item>
    </style>
    <style name="WidgetEntryDate" parent="style/AppTheme">
        <item name="android:textSize">20sp</item>
        <item name="android:textColor">@android:color/black</item>
    </style>
</resources>

Then, use the styles in mywidget_layout.xml :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    ...>

    <TextView style="@style/WidgetEntryTitle"
        ... />

    <TextView style="@style/WidgetEntryDate"
        ... />
</RelativeLayout>
