First I should prolly ask if it is indeed possible to do what I’m trying to do.<\/p>\n

I have a custom RelativeView and it contains 4 TextViews and a button defines in an xml layout.<\/p>\n

\n\n      \n       \n      \n      \n      \n      \n\n<\/code><\/pre>\n
This I inflated the views into the RelativeLayout class.<\/p>\n
public void init() {\n        LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);\n\n        mReadDisplay = (TextView)inflater.inflate(R.id.digi_reading, this, true);\n            mReadDisplay.setTypeface(Typeface.createFromAsset(context.getAssets(),\n                    \"font\/DIGITALDREAM.ttf\"));\n            mReadDisplay.setTextSize(18f);\n        mHeadDisplay = (TextView)inflater.inflate(R.id.digi_header, this, true);\n            mHeadDisplay.setTextSize(14f);\n        mMeasureDisplay = (TextView)inflater.inflate(R.id.digi_measurement, this, true);\n            mMeasureDisplay.setTextSize(10f);\n        mTypeDisplay = (TextView)inflater.inflate(R.id.digi_type, this, true);\n            mTypeDisplay.setTextSize(10f);\n        mGrouping = (Button)inflater.inflate(R.id.digi_grouping, this, true);\n            mGrouping.setBackgroundColor(0x00000000);\n    }\n<\/code><\/pre>\n
Everything looks good so far, so I run it and get a massive xml crash saying that it can’t find my resource. Is it because I embedded it in the custom RelativeLayout?<\/p>\n

And this is the first part of the class. It has to deal with initializing the layout.<\/p>\n

    \n
  1. \n
    As mreichelt pointed out in a comment, your use of Layout.inflate seems suspicious. You probably want to do something more like this:<\/p>\n
        \/\/ Assume that the XML file from your question (above) is named MyLayoutFile.xml \n    \/\/ Digital is your derived layout class\n    Digital layout = (Digital) inflater.inflate(R.layout.MyLayoutFile, this, true);\n\n    mReadDisplay = (TextView) layout.findViewById(R.id.digi_reading);\n    \/\/...\n    mHeadDisplay = (TextView) layout.findViewById(R.id.digi_header);\n    \/\/...\n    mMeasureDisplay = (TextView) layout.findViewById(R.id.digi_measurement);\n<\/code><\/pre>\n
    and so on. Notice especially that the ID passed into inflater.inflate<\/code> is prefixed with R.layout.<\/code>, whereas the ID passed into findViewById<\/code> is prefixed with R.id.<\/code> (Unfortunately, passing the wrong kind of resource identifier will never generate a compile-time error.)<\/p>\n<\/li>\n
  2. \n
    You are doing it wrong, you only call inflate for the root view.<\/p>\n
    com.android.appionresourcemanager.Widgets.Digital mDigital = (Digital)View.inflate(this, R.layout.mylayout, null);\n mReadDisplay = (TextView)mDigital.findViewById(R.id.digi_reading);\n \/\/....\n<\/code><\/pre>\n
    hope this helps!<\/p>\n<\/li>\n<\/ol>\n
