我从谷歌收到此错误日志,我不知道是什么导致它。此资源位于文件夹中,表示不是。我自己从未遇到过这个错误。这是错误:
android.content.res.Resources$NotFoundException: File res/drawable-mdpi/notebook_ul.jpg from drawable resource ID #0x7f020090
at android.content.res.Resources.loadDrawable(Resources.java:1714)
at android.content.res.Resources.getDrawable(Resources.java:581)
at android.view.View.setBackgroundResource(View.java:7391)
at com.bfreq.dice.fragments.SettingsFrag.onCreateView(SettingsFrag.java:76)
..............................
Caused by: java.lang.NullPointerException.........
这是我在我的片段中调用资源
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View v = inflater.inflate(R.layout.settings, container, false);
// Initializing Background
rLayout = (RelativeLayout) v.findViewById(R.id.relativeLayout_Settings);
switch (background) {
case 0:
rLayout.setBackgroundResource(R.drawable.clay_ul);
break;
case 1:
rLayout.setBackgroundResource(R.drawable.parchment_ul);
break;
case 2:
rLayout.setBackgroundResource(R.drawable.brownpaper_ul);
break;
case 3:
rLayout.setBackgroundResource(R.drawable.notebook_ul);
break;
case 4:
rLayout.setBackgroundColor(Color.WHITE);
break;
}
........
return v;
}
我也是从方法中调用它。现在我知道我不会直接从一个片段到另一个片段进行对话,但它一直没有问题,没有时间重写所有内容。
public void setBackground() {
switch (background) {
case 0:
SettingsFrag.rLayout.setBackgroundResource(R.drawable.clay_ul);
DiceFrag.rLayout.setBackgroundResource(R.drawable.clay_uc);
DiceLogFrag.rLayout.setBackgroundResource(R.drawable.clay_ur);
break;
case 1:
SettingsFrag.rLayout.setBackgroundResource(R.drawable.parchment_ul);
DiceFrag.rLayout.setBackgroundResource(R.drawable.parchment_uc);
DiceLogFrag.rLayout.setBackgroundResource(R.drawable.parchment_ur);
break;
case 2:
SettingsFrag.rLayout.setBackgroundResource(R.drawable.brownpaper_ul);
DiceFrag.rLayout.setBackgroundResource(R.drawable.brownpaper_uc);
DiceLogFrag.rLayout.setBackgroundResource(R.drawable.brownpaper_ur);
break;
case 3:
SettingsFrag.rLayout.setBackgroundResource(R.drawable.notebook_ul);
DiceFrag.rLayout.setBackgroundResource(R.drawable.notebook_uc);
DiceLogFrag.rLayout.setBackgroundResource(R.drawable.notebook_ur);
break;
case 4:
SettingsFrag.rLayout.setBackgroundColor(Color.WHITE);
DiceFrag.rLayout.setBackgroundColor(Color.WHITE);
DiceLogFrag.rLayout.setBackgroundColor(Color.WHITE);
break;
}
}
每当我调用该方法时,我都会确保它不会返回空指针。任何想法都会很棒。如果有人想看,我还可以添加更多代码。谢谢!

当我为特定dpi创建一个资产(即hdpi,xhdpi ...)时,我得到此信息,请确保您的drawable在drawable/
,drawable-hdpi/
,{{1}中可用您可能在一个drawable-mdpi/
目录中创建了一个drawable,但不是当前仿真器/设备所从的目录。
