Question

我在我的应用程序中使用自定义字体用于文本视图，当我使用这些字体时，我发现它消耗了大量内存（泄漏内存）。每次进入此活动时，堆大小都会增加，我使用此字体。当我从这个类中删除文本视图的自定义字体时，我注意到内存消耗减少了。请查看我的示例代码。我发布在

下面

 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，请在使用自定义视图时查看内存愚蠢。

我已将自定义字体放入资源中。谁能指出我哪里出错了。在这种情况下，任何帮助都非常感谢。

使用自定义字体时这是一个非常常见的内存泄漏，我在此问题报告中有解决方案：https://code.google.com/p/android/issues/detail?id=9904
