瓷砖绘制有时会延伸 [英] Tiled drawable sometimes stretches

问题描述

我有一个ListView的项目有一个平铺背景。要做到这一点，我用下面绘制的xml：

I have a ListView whose items have a tiled background. To accomplish this, I use the following drawable xml:

<bitmap
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/tile"
    android:tileMode="repeat" />

通常情况下，这个工程。但是，有时在src绘制不是平铺，而是延伸至整个列表项。 （我有几个不同的瓷砖这样的，我用它们混合在一个ListView中，如果有拉伸，而不是平铺，它从来没有在所有的人一下子，什么是值得。）

Usually, this works. Sometimes, however, the src drawable isn't tiled, but stretched to fill the entire list item. (I've got several different tiles like this, and I use them mixed in one ListView. If there is stretching instead of tiling, it's never been in all of them at once, for what that's worth.)

我也尝试添加安卓抖动=真正的到XML，因为我读的地方，没有它可能存在错误。这并没有改变任何东西。

I also tried to add android:dither="true" to that xml, since I read somewhere that without it there might be bugs. That didn't change anything.

有没有人有同样的问题？你是怎么解决的呢？

Has anyone had the same problem? How did you fix it?

推荐答案

我也得到了咬了这个问题。非常难以诊断，甚至难以找到类似的报告和可用的解决方案。

I also got bitten by this problem. Very hard to diagnose, even harder to find similar reports and usable solutions.

小吃就在freenode＃Android的开发IRC频道附带以下实用的方法：

"Tapas" on the freenode #android-dev irc channel came with the following utility method:

public static void fixBackgroundRepeat(View view) {
    Drawable bg = view.getBackground();
    if (bg != null) {
        if (bg instanceof BitmapDrawable) {
            BitmapDrawable bmp = (BitmapDrawable) bg;
            bmp.mutate(); // make sure that we aren't sharing state anymore
            bmp.setTileModeXY(TileMode.REPEAT, TileMode.REPEAT);
        }
    }
}

将其应用到所有具有瓷砖后台设置视图​​（如findViewById他们）。

Apply it to all Views that have a tiled background set (e.g. findViewById them).

另外，我有IM pression这个bug开始设置后演戏anyDensity =真在AndroidManifest.xml中

Also, I have the impression this bug started acting up after setting "anyDensity=true" in AndroidManifest.xml
