Error inflating my Custom TextView from Library

Question

I have customTextView that loads from my custom Library. but it can't inflate in main_layout and my app stops working. I find that If I put MyTextView in main project it works fine and the problem is load from myLib.

public class MyTextView extends TextView {


    public MyTextView(Context context){
    super(context);

}

public MyTextView(Context context, AttributeSet attrs) {
    super(context, attrs);

    initAttr(attrs);
}

public MyTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);

    initAttr(attrs);
}


    private void initAttr(AttributeSet attrs) {
        TypedArray a=getContext().obtainStyledAttributes(
                attrs,
                R.styleable.myView);

        super.setText("blablabla");



        a.recycle();
    }

I get this warning in xml designing: the following classes could not be found on my custom class , although the class loads Auto completely! so I think some thing wrong with library. I create library in android studio by Project Strucure / new module / android library

this is how I call it:

   <com.kenji.mylib.MyTextView
        android:layout_width="50dp"
        android:layout_height="50dp"/>

and this is the error:

yes, can you please post an error, and the code, how you're trying to inflate this TextView — Chaosit, Apr 29 '15 at 10:15

public class MyTextView extends TextView
{
    public MyTextView(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
        init();
    }
    public MyTextView(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        init();
    }
    public MyTextView(Context context)
    {
        super(context);
        init();
    }
    private void init()
    {
        setText("blablabla");
    }
}

And in your layout

<yourpackage.MyTextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

I just delete the excluded possible mistakes...

EDIT

next possible mistake, Your TypedArray:

  TypedArray a=getContext().obtainStyledAttributes(
            attrs,
            R.styleable.myView);

But Your stylable is called MyAttrs, so it should be:

  TypedArray a=getContext().obtainStyledAttributes(
            attrs,
            R.styleable.MyAttrs);

But You have to obtain Your attributes, like this:

public MyTextView(Context context, AttributeSet attrs) {
    super(context, attrs);

    TypedArray a=context.obtainStyledAttributes(
                attrs,
                R.styleable.MyAttrs);
}

public MyTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);

    TypedArray a=context.obtainStyledAttributes(
                attrs,
                R.styleable.MyAttrs);
}

then, how do You have build Your lib and how implemented? – Opiatefuchs Apr 29 '15 at 12:33 — Opiatefuchs, Apr 29 '15 at 12:33

Make sure u must define necessary resources/assets in build.gradle file

  sourceSets {
    main {
      manifest.srcFile 'AndroidManifest.xml'
      java.srcDirs = ['src']
      res.srcDirs = ['res']
      assets.srcDirs = ['assets']
    }

In my case i was missing the declaration for assets

It's because that the app and library package name clashes. you must change one of them.
