Fragment填坑

坑A

 No view found for id 0x1020368 (android:id/webviewchromium_color_picker_text) for fragment DeviceConnectFragment{654df8c8 #0 id=0x1020368 com.***.***.***.fragment.DeviceConnectFragment}

如果你看到了如下error，但是这个error有很多种引起的原因，大部分是因为Fragment嵌套。我碰到的原因是：

• Fragment没用进行嵌套
• 使用的是PreferenceActivity和PreferenceFragment配合出现的error
• 使用系统布局替换新Fragment（不是自己写的layout）

出错的是这句

transaction.replace(com.android.internal.R.id.prefs, new DeviceConnectFragment(), FRAGMENT_NAME);

当使用系统布局的时候，在低版本上面，会出现上面的问题。

解决方案

int identifier = Resources.getSystem().getIdentifier("prefs", "id", "android");
transaction.replace(identifier, new DeviceConnectFragment(), FRAGMENT_NAME);

就解决了
