kam*_*ych 8 xml android bitmap repeat statelist
这是我的自定义选择器(StateListDrawable)
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="@drawable/common_cell_background" />
<item
android:state_pressed="true"
android:drawable="@drawable/common_cell_background_highlight" />
<item
android:state_focused="true"
android:drawable="@drawable/common_cell_background_highlight" />
<item
android:state_selected="true"
android:drawable="@drawable/common_cell_background_highlight" />
</selector>

common_cell_background和common_cell_background_highlight都是XML.代码如下:
common_cell_background.xml
<bitmap
xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/common_cell_background_bitmap"
android:tileMode="repeat"
android:dither="true">

android:src="@drawable/common_cell_background_bitmap_highlight"
android:tileMode="repeat"
android:dither="true">

位图也完全相同.亮点只是稍微轻一点,没有其他差异.两个位图都是PNG文件.
现在我开始了
convertView.setBackgroundResource(R.drawable.list_item_background);

这是问题所在.我的common_cell_background没有重复,它已经拉长了.但是,当我触摸列表背景的单元格时,令人惊讶的是变为common_cell_background_highlight并猜测是什么?一切都很好,它应该像它应该重复.我不知道问题出在哪里,为什么我的背景不会重复突出显示.有什么想法吗?
这是错误,已在 ICS 中修复,请参阅此答案:/sf/answers/533058431/

请注意,该解决方法仅适用于BitmapDrawable
,对于其他类型的可绘制对象,例如StateListDrawable
您需要做额外的工作。这是我使用的:
public static void fixBackgrndTileMode(View view, TileMode tileModeX, TileMode tileModeY) {
if (view != null) {
Drawable bg = view.getBackground();
if (bg instanceof BitmapDrawable) {
BitmapDrawable bmp = (BitmapDrawable) bg;
bmp.mutate(); // make sure that we aren't sharing state anymore
bmp.setTileModeXY(tileModeX, tileModeY);
}
else if (bg instanceof StateListDrawable) {
StateListDrawable stateDrwbl = (StateListDrawable) bg;
stateDrwbl.mutate(); // make sure that we aren't sharing state anymore
ConstantState constantState = stateDrwbl.getConstantState();
if (constantState instanceof DrawableContainerState) {
DrawableContainerState drwblContainerState = (DrawableContainerState)constantState;
final Drawable[] drawables = drwblContainerState.getChildren();
for (Drawable drwbl : drawables) {
if (drwbl instanceof BitmapDrawable)
((BitmapDrawable)drwbl).setTileModeXY(tileModeX, tileModeY);
}
}
}
}
}
