我在应用程序中的 TextView 中使用自定义字体，当我使用这些字体时，我发现它消耗了大量内存(泄漏内存)。每次我进入此 Activity 并使用此字体时，堆大小都会增加。当我从此类中删除 TextView 的自定义字体时，我注意到内存消耗减少了。请查看我的示例代码。我在下面发布
public class TrebuchetItalicTextView extends TextView {
private static final String fontName = "Trebuchet-ms-italic";
public TrebuchetItalicTextView(Context context, AttributeSet attrs) {
super(context, attrs);
if (!isInEditMode()) {
synchronized (PSDataCache.getSharedCache().getFontCache()) {
if (!PSDataCache.getSharedCache().getFontCache()
.containsKey(fontName)) {
Typeface tf = Typeface.createFromAsset(context.getAssets(),
"fonts/trebucit_0.ttf");
PSDataCache.getSharedCache().setFontCache(fontName, tf);
}
setTypeface(PSDataCache.getSharedCache().getFontCache()
.get(fontName));
}
}
}
}
我在 XML 中使用此类，如下所示。
<com.android.customviews.TrebuchetItalicTextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginLeft="15dp"
android:text="Lorem ipsum dolor sit amet."
android:textColor="#727272"
android:textSize="16sp"
android:textStyle="italic" />
另外，当使用自定义 View 时，请看一下内存愚蠢。

我已将自定义字体放入 Assets 中。谁能指出我哪里错了。非常感谢在这种情况下的任何帮助。
最佳答案
这是使用自定义字体时非常常见的内存泄漏，我对此问题报告有解决方案:https://code.google.com/p/android/issues/detail?id=9904
关于android - Android 中的自定义字体泄漏内存，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23977114/
